Radiography (Lond) 2024; 30:1116-1124. [PMID: 38797044 DOI: 10.1016/j.radi.2024.05.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 05/10/2024] [Accepted: 05/14/2024] [Indexed: 05/29/2024]
Abstract
INTRODUCTION Information on tissue perfusion in the foot is important when treating patients with chronic limb-threatening ischemia. This study aims to test the reliability of different magnetic resonance sequences when measuring perfusion in the foot. METHODS Sixteen healthy volunteers had their right foot scanned in a test/retest study with six different magnetic resonance sequences (BOLD, multi-echo gradient echo (mGRE), 2D and 3D pCASL, PASL FAIR, and DWI with intravoxel incoherent motion (IVIM) with quantitative measurements of perfusion. For five sequences, cuff-induced ischemia followed by a hyperactive response was measured. Images of the feet were segmented into angiosomes and perfusion data were extracted from the five angiosomes. RESULTS BOLD, PASL FAIR, mGRE, and DWI with IVIM had low mean differences between the first and second scans, while the results of 2D and 3D pCASL had the highest differences. Based on a paired t-test, BOLD, and FAIR were able to distinguish between perfusion and no perfusion in all angiosomes with p-values below 0.01. This was not the case with 2D and 3D pCASL with p-values above 0.05 in all angiosomes. The mGRE could not distinguish between perfusion and no perfusion in the lateral side of the foot. CONCLUSION BOLD, mGRE, pASL FAIR, and DWI with IVIM seem to give more robust results compared to 2D and 3D pCASL. Further studies on patients with peripheral artery disease should explore if the sequences can have clinical relevance when assessing tissue ischemia and results of revascularization. IMPLICATIONS FOR PRACTICE This study provides knowledge that could be used to improve the diagnosis of patient with chronic limb-threatening ischemia to explore tissue perfusion.

Abstract
AIM The "2024 ACC/AHA/AACVPR/APMA/ABC/SCAI/SVM/SVN/SVS/SIR/VESS Guideline for the Management of Lower Extremity Peripheral Artery Disease" provides recommendations to guide clinicians in the treatment of patients with lower extremity peripheral artery disease across its multiple clinical presentation subsets (ie, asymptomatic, chronic symptomatic, chronic limb-threatening ischemia, and acute limb ischemia). METHODS A comprehensive literature search was conducted from October 2020 to June 2022, encompassing studies, reviews, and other evidence conducted on human subjects that was published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through May 2023 during the peer review process, were also considered by the writing committee and added to the evidence tables where appropriate. STRUCTURE Recommendations from the "2016 AHA/ACC Guideline on the Management of Patients With Lower Extremity Peripheral Artery Disease" have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with peripheral artery disease have been developed.

Abstract
OBJECTIVES The angiosome concept has significantly impacted diabetic foot ulcer management by highlighting the vascular anatomy's role in wound healing. However, its clinical applicability and validity remain debated due to complexities in foot blood supply and ulcer location determination. METHODS A cross-sectional study was conducted on 84 individuals with diabetic foot ulcers undergoing lower limb angiography. Demographics, ulcer characteristics, and angiographic data were collected and analyzed using descriptive statistics and relevant tests. RESULTS Digital subtraction angiography assessed 89 limbs with diabetic foot ulcers; males comprised 54.8%, primarily type 2 diabetes (96.4%), averaging 64.36 ± 10.09 years. Of 129 angiosomes, angiosome 2 (40.3%) had the highest ulcer incidence. Posterior tibial artery (PTA) involvement was predominant (72.9%), while external iliac artery (EIA) and profunda femoris artery (PFA) were least affected (2.4% each). Posterior tibial artery showed 46.5% complete occlusion. Angiosome 2 correlated notably with anterior tibial artery (ATA), peroneal artery (CPA), and PTA, but categorizing angiosomes by supply patterns showed no significant artery correlation (p > .05). CONCLUSIONS The research indicates inconsistent support for below-the-knee artery involvement correlating with foot ulcer locations in angiosomes. While aiding vascular comprehension, the angiosome concept may not fully elucidate lower limb vascular complexities and ulcer genesis. Factors like collateral circulation should be noticed to understanding ulcer localization and severity, extending beyond angiosomal arterial supply.

Abstract
PURPOSE The purpose of this review and meta-analysis is to determine the clinical outcome differences between patients with chronic limb-threatening ischemia who underwent direct versus indirect angiosome revascularization using either the surgical or endovascular approach. MATERIALS AND METHODS The data sources used for article selection included PubMed, Embase/Medline, Cochrane reviews, and Web of Science (All studies were in English and included up to September 2023). All articles included were comparative in design, including retrospective, prospective, and randomized controlled trials that compared the clinical outcomes between direct and indirect angiosome-guided revascularization in chronic limb-threatening ischemia. A random-effects model was used to determine the measure of association between direct revascularization and amputation-free survival, wound healing, and overall survival. Publication bias was assessed with both Begg's and Egger's test, and heterogeneity was calculated using an I2. RESULTS Data from 9 articles were analyzed and reported in this review. Direct revascularization was associated with improved amputation-free survival (odds ratio [OR]=2.632, confidence interval [CI]: 1.625, 4.265), binary wound healing (OR=2.262, CI: 1.518, 3.372), and overall survival (OR=1.757, CI: 1.176, 2.625). Time until wound healed was not associated with either direct or indirect revascularization (Standard Mean Difference [SMD]=-2.15, p=0.11). There was a low risk of bias across all studies according to the RoB 2.0 tool. CONCLUSION Direct revascularization is associated with improved amputation-free survival, overall survival, and wound healing in chronic limb-threatening ischemic patients compared to the indirect approach. CLINICAL IMPACT Preservation of the lower extremity is critical for preventing mortality and maintaining independence. The benefit of angiosome-guided revascularization for chronic limb-threatening ischemia remains controversial. The authors of this article aim to review the current literature and compare direct and indirect angiosome-guided intervention for preserving the lower extremity. Current findings suggest direct angiosome-guided intervention reduces amputation rates and improves survival; however, many trials neglect to address the multifactorial approach needed in wound care management.

Abstract
BACKGROUND Chronic limb-threatening ischemia (CLTI) in patients with end-stage renal disease (ESRD) poses significant challenges in clinical management due to its unique pathology and poor treatment outcomes. This review calls for a tailored classification and risk assessment for these patients to guide better revascularization choices with early minor amputation as a first-line strategy in advanced stages. METHODS This review consolidates key findings from recent literature on CLTI in ESRD, focusing on disease mechanisms, treatment options, and patient outcomes. It evaluates the literature to clarify the decision-making process for managing CLTI in ESRD. RESULTS CLTI in ESRD patients often results in worse clinical outcomes, such as nonhealing wounds, increased limb loss, and higher mortality rates. While the literature reveals ongoing debates regarding the optimal revascularization method, recent retrospective studies and meta-analyses suggest potential benefits of endovascular treatment (EVT) over open bypass surgery (OB) in reducing mortality and wound complications, with comparable amputation-free survival rates. CONCLUSIONS The selection of revascularization methods in ESRD patients with CLTI is complex, necessitating individualized strategies. The importance of early detection and timely intervention is critical to decelerate disease progression and improve revascularization outcomes. There is a shift in these treatment strategies toward less invasive endovascular procedures, acknowledging the limitations these patients face with open revascularization surgeries. Considering early minor amputations after revascularization could prevent worse consequences, reflecting a shift in the approach to managing CLTI in ESRD patients.

Abstract
OBJECTIVES Many factors affect long-term outcomes after open bypass in patients with chronic limb-threatening ischemia (CLTI). Ambulatory status has been suggested to be associated with clinical outcomes, but there is limited knowledge on the effect of gait speed on outcomes. The purpose of this study is to evaluate the effect of gait speed assessed in a 6-min walk test (6MWT) on outcomes after crural and pedal bypass in patients with CLTI. METHODS A retrospective analysis was performed in patients with CLTI who underwent a 6MWT at 1 month after crural and pedal bypass at a single center from 2014 to 2021. Comparisons were made between those with high gait speed (HG group, 6-min walk distance (6MWD) > 288 m) and those with low gait speed (LG group, 6MWD ≤288 m). The primary endpoint was survival, and the secondary endpoints were graft patency, limb salvage, wound healing, major adverse cardiovascular events (MACEs), and hospital outcomes. RESULTS Of 104 patients with CLTI who underwent a 6MWT after crural and pedal bypass, 46 (44%) and 58 (56%) were placed in the HG and LG groups, respectively. The LG group was older (p < .001), had more female subjects (p = .006), and had a higher prevalence of cerebrovascular disease (p = .042) and tissue loss (p = .007). The median follow-up was 36 (22-57) months. The HG group had significantly higher 3-year primary patency (65% vs 42%, p = .013), 3-year secondary patency (87% vs 66%, p = .018), 3-year overall survival (89% vs 58%, p < .001), and 3-year freedom from MACE (79% vs 67%, p = .039). The 3-year limb salvage and 12-month wound healing rates did not differ between the groups. CONCLUSIONS Gait speed in patients with CLTI after crural and pedal bypass was associated with survival, freedom from MACE, and graft patency but not with limb salvage and wound healing. A detailed study of walking ability in these patients may be needed in the future.

Abstract
OBJECTIVE There is no established consensus or guidelines for wound management after revascularization for patients with chronic limb-threatening ischemia (CLTI) without severe infection. This study is designed to evaluate the clinical effect of the wound management strategy on toe wounds after revascularization for CLTI. METHODS This retrospective cohort study was performed at eight institutions affiliated with Keio University School of Medicine in Japan and included 261 patients who underwent revascularization for CLTI between April 2019 and July 2021. We identified 132 patients with toe wounds from the database who had restored in-line blood flow to the foot. Patients were divided into two groups by the timing of toe resection after revascularization, which dictated the wound management policy. Group A (62 patients) underwent early toe amputation for suspected osteomyelitis, whereas group B (70 patients) underwent watchful waiting. The primary outcome was wound healing after revascularization; the secondary outcome was major amputation. We compared outcomes between groups A and B after propensity score matching. RESULTS Using propensity score matching, each patient in group A (33 patients) was matched with a patient in group B (33 patients). Wound healing in matched group A was significantly better than that in matched group B (respectively: 1-year wound healing rate: 90.0% vs 68.2%, P < .001; median wound healing time: 65 days vs 258 days, P < .01). Although five major amputations were necessary in matched group B, none were required in matched group A (P = .05). The high rate of major amputations in group B was attributed to the sudden exacerbation of infection. Limb salvage rate in matched group A exceeded matched group B (100.0% vs 90.5%: 1-year limb salvage rate, P = .02). CONCLUSIONS Early toe amputation for highly suspected osteomyelitis in patients with CLTI with toe wounds may expedite wound healing compared with watchful waiting, potentially avoiding unnecessary major amputation. Considering the wound management strategy is crucial when evaluating wound healing outcomes in patients with CLTI with revascularization.

J Clin Med 2024; 13:883. [PMID: 38337576 PMCID: PMC10856460 DOI: 10.3390/jcm13030883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 01/22/2024] [Accepted: 01/26/2024] [Indexed: 02/12/2024] Open
Abstract
Background: Revascularization based on the angiosome concept (AC) is a controversial subject because there is currently no clear evidence of its efficacy, due to the heterogeneity of patients (multiple and diverse risk factors and comorbidities, multiple variations in the affected angiosomes). Choke vessels change the paradigm of the AC, and the presence or absence of the plantar arch directly affects the course of targeted revascularization. The aim of this study was to evaluate the effect of revascularization based on the AC in diabetic patients with chronic limb-threatening ischemia (CLTI). Methods: This retrospective analysis included 51 patients (40 men, 11 women), with a mean age of 69 years (66-72) and a total of 51 limbs, who presented with Rutherford 5-6 CLTI, before and after having undergone a drug-coated balloon angioplasty (8 patients) or plain balloon angioplasty (43). Between November 2018 and November 2019, all patients underwent below-the-knee balloon angioplasties and were followed up for an average of 12 months. The alteration of microcirculation was compared between directly and indirectly revascularized angiosomes. The study assessed clinical findings and patient outcomes, with follow-up investigations, comparing wound healing rates between the different revascularization methods. Patient records and periprocedural leg digital subtraction angiographies (DSA) were analyzed. Differences in outcomes after direct revascularization and indirect percutaneous transluminal angioplasty (PTa) were examined using Cox proportional hazards analysis, with the following endpoints: ulcer healing, limb salvage, and also amputation-free survival. Results: Direct blood flow to the angiosome supplying the ulcer area was achieved in 38 legs, in contrast to 13 legs with indirect revascularization. Among the cases, there were 39 lesions in the anterior tibial artery (ATA), 42 lesions in the posterior tibial artery (PTA), and 8 lesions in the peroneal artery (PA). According to a Cox proportional hazards analysis, having fewer than three (<3) affected angiosomes (HR 0.49, 95% CI 0.19-1.25, p = 0.136) was associated with improved wound healing. Conversely, wound healing outcomes were least favorable after indirect angioplasty (p = 0.206). When adjusting the Cox proportional hazard analysis for the number of affected angiosomes, it was found that direct drug-coated angioplasty resulted in the most favorable wound healing (p = 0.091). At the 1-year follow-up, the major amputation rate was 17.7%, and, according to a Cox proportional hazards analysis, atrial fibrillation (HR 0.85, 95% CI 0.42-1.69, p = 0.637), hemodialysis (HR 1.26, 95% CI 0.39-4.04, p = 0.699), and number of affected angiosomes > 3 (HR 0.94, 95% CI 0.63-1.39, p = 0.748) were significantly associated with poor leg salvage. Additionally, direct endovascular revascularization was associated with a lower rate of major amputation compared to indirect angioplasty (HR 1.09, 95% CI 0.34-3.50, p = 0.884). Conclusions: Observing the angiosomes concept in decision-making appears to result in improved rates of arterial ulcer healing and leg salvage, particularly in targeted drug-coated balloon angioplasty for diabetic critical limb ischemia, where multiple angiosomes are typically affected.

Abstract
PURPOSE Surgical revascularization is the standard treatment for chronic limb-threatening ischemia (CLTI). However, some patients may require reintervention. The Global Anatomic Staging System (GLASS), which evaluates the complexity of infrainguinal lesions, was proposed. This study aimed to identify predictors for graft revision and evaluate whether GLASS impacts vein graft revision. METHODS Between 2011 and 2018, CLTI patients who underwent de novo infrapopliteal bypass using autogenous veins were retrospectively analyzed. To assess anatomic complexity with GLASS, femoropopliteal, infrapopliteal, and inframalleolar/pedal (IM) disease grades were determined. The outcomes of patients with or without graft revision were compared. Cox regression analysis was performed. RESULTS Thirty-six of the 80 patients underwent reintervention for graft revision. Compared to the non-graft revision group, the graft revision group exhibited significantly higher rates of GLASS stage III (66% vs 81%, p = 0.046) and grade P2 IM disease (25% vs 58%, p = 0.009). Multivariate analysis revealed that IM grade P2 (hazard ratio [HR], 3.35; 95% confidence interval [CI], 1.66-6.75; p = 0.001) and spliced vein grafts (HR, 3.18; 95% CI, 1.43-7.06; p = 0.005) were significantly associated with graft revision. CONCLUSIONS This study demonstrated that IM grade P2 and spliced vein grafts were predictors of graft revision. The GLASS stratification of IM disease grade may be useful in optimizing treatment for CLTI.

Abstract
Chronic limb-threatening ischemia (CLTI) is associated with a short-term risk of limb loss. Multidisciplinary teams are often involved in CLTI treatment; however, in Asian countries, multidisciplinary teams that include podiatrists specializing in foot wounds and vascular surgeons who can perform distal bypass surgery are lacking. We investigated predictive factors for limb salvage and foot ulcer recurrence in patients with CLTI treated by a Japanese single-center intensive multidisciplinary team over 6 years. We retrospectively investigated 84 patients with CLTI and foot ulcers who had undergone revascularization and wound treatment between October 2013 and December 2019. Following postrevascularization treatment, including undertaking minor amputations, the healing rate was 77.8%, and the average wound healing time was 75 ± 68 days. To achieve adequate blood supply, 17.7% of patients were treated using a combination of endovascular revascularization and bypass surgeries. Thirty-three (44%) patients had wound recurrence and there was wound recurrence within 6 months in 58.9% of these patients. Multivariate logistic regression analysis showed that postrevascularization skin perfusion pressure was significantly associated with wound healing (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.033-1.243, P = .0078). Diabetes mellitus (OR 9.72, 95% CI 1.855-50.937, P = .0071), and heart disease (OR 3.51, 95% CI 1.052-11.693, P = .0411) were significantly associated with wound recurrence (P < .05). Treatment within a single-center intensive multidisciplinary team resulted in good patient outcomes. Our study indicates that the revascularization endpoint of CLTI treatment should be marked by attainment of adequate blood supply and wound healing. The timing of revascularization and debridement is of utmost importance for the successful treatment of CLTI wounds.

Abstract
OBJECTIVES Patients with chronic limb-threatening ischemia (CLTI) have a high risk of lower limb amputation and loss of walking independence. Minor amputations play a key role in ensuring walking independence and they represent a challenge in terms of timing and level for vascular surgeons. A major cause of re-amputation is a defect in wound healing and a possible predictor of re-amputation for non-healing wounds could be the incorrect timing of minor amputation after revascularization. The lack of evidence in the literature leads to a wide variability of choices in clinical practice. The purpose of this study was to try to find the optimal timing analysing the risk of re-amputation in CLTI patients who have undergone successful revascularization and minor amputation focussing on timing of minor amputation. METHODS We conducted a single centre retrospective analysis on a cohort of 151 patients consecutively admitted to our hospital for CLTI (Rutherford 5) between January 2014 and April 2022. All the enrolled patients underwent successful revascularization of lower limbs and a minor amputation for dry acral necrosis. The characteristics of the patients and the revascularization procedures were collected and analysed. Patients were divided into two groups based on the timing of minor amputation performed before (group 1) or after the day (group 2) that best predicts the risk of re-amputation according to a Receiver Operating Characteristic (ROC) curve analysis. The primary outcome of this study was the risk of re-amputation during the first 60 days of follow-up after a primary minor amputation, with revascularization still effective. The impact of the timing of minor amputation after revascularization, the type of revascularization and the presence of risk factors known to prolong the wound healing process were evaluated in a uni- and multi-variable logistic regression model. RESULTS Systemic hypertension, and type of revascularization (i.e. open vs endovascular) were independent predictors of the risk of re-amputation at 60 days (HR 4.26, 95% CI 1.30-14.04, p = .017 and HR 2.35, 95% CI 1.16-4.78, p = .018, respectively). Moreover, time ≤14 days between revascularization and first amputation was associate with a clear, albeit not statistically significant, trend toward increased risk of re-amputation (HR 2.09, 95% CI 0.97-4.51, p = .06). CONCLUSIONS In a cohort of patients who underwent a successful revascularization for CLTI and a minor amputation for dry gangrene in the first 14 days after revascularization, a higher -although not significant-risk of re-amputation was reported. In this cohort of patients, a delayed demolitive procedure should be considered to allow better tissue perfusion and to reduce the risk of re-amputation.

Abstract
Diabetes related foot complications have become a major cause of morbidity and are implicated in most major and minor amputations globally. Approximately 50% of people with diabetes and a foot ulcer have peripheral artery disease (PAD) and the presence of PAD significantly increases the risk of adverse limb and cardiovascular events. The International Working Group on the Diabetic Foot (IWGDF) has published evidence based guidelines on the management and prevention of diabetes related foot complications since 1999. This guideline is an update of the 2019 IWGDF guideline on the diagnosis, prognosis, and management of peripheral artery disease in people with diabetes mellitus and a foot ulcer. For this updated guideline, the IWGDF, the European Society for Vascular Surgery, and the Society for Vascular Surgery decided to collaborate to develop a consistent suite of recommendations relevant to clinicians in all countries. This guideline is based on three new systematic reviews. Using the Grading of Recommendations, Assessment, Development and Evaluation framework clinically relevant questions were formulated, and the literature was systematically reviewed. After assessing the certainty of the evidence, recommendations were formulated which were weighed against the balance of benefits and harms, patient values, feasibility, acceptability, equity, resources required, and when available, costs. Through this process five recommendations were developed for diagnosing PAD in a person with diabetes, with and without a foot ulcer or gangrene. Five recommendations were developed for prognosis relating to estimating likelihood of healing and amputation outcomes in a person with diabetes and a foot ulcer or gangrene. Fifteen recommendations were developed related to PAD treatment encompassing prioritisation of people for revascularisation, the choice of a procedure and post-surgical care. In addition, the Writing Committee has highlighted key research questions where current evidence is lacking. The Writing Committee believes that following these recommendations will help healthcare professionals to provide better care and will reduce the burden of diabetes related foot complications.

Abstract
BACKGROUND The risk of coronary artery disease in peripheral arterial disease (PAD) is high, life prognosis is poor, and lipid-lowering treatment with statins has been reported to improve prognosis. In clinical practice, however, hypolipidemia is more common in patients with severe PAD and statin prescription rates appear to be low, but specific data are scarce in Japan. Therefore, we conducted this cross-sectional study in collaboration with other centers of vascular surgery to determine the rate of statin prescriptions for PAD patients in real-world practice, the rate of achievement of low-density lipoprotein (LDL) cholesterol control targets, and whether statin non-use is a determinant factor of critical limb ischemia (CLI). METHODS A total of 246 PAD patients (97 with CLI) from 5 sites were included in this study. Medical history and blood test data were obtained from medical records and interviews with patients, and were compared between CLI and non-CLI patients. RESULTS Statin prescription rate was only 34 %. The overall LDL cholesterol control target rate was 46 % of CLI cases and 51 % of non-CLI cases, according to the lipid management criteria of the Japanese Society for Atherosclerosis 2022 guidelines. Patients in the CLI group had a lower mean body mass index and lower LDL cholesterol levels than those in the non-CLI group, suggesting that these factors were responsible for the lower statin prescription rate. However, multivariate analysis revealed that statin non-use was one of the determinants of CLI. CONCLUSIONS Statin prescription rates for PAD patients were low in real-world practice settings in the field of vascular surgery. Since statin non-use is a determinant of CLI, there is a need to educate physicians engaged in treatment regarding lipid-lowering treatment with statins.

Abstract
INTRODUCTION Lipoprotein apheresis (LA) is a possible adjunct treatment for no-option chronic limb-threatening ischemia (CLTI). This study aimed to assess the impact of a novel LA for no-option CLTI. METHODS We retrospectively assessed 19 patients with no-option CLTI treated using the novel LA. The primary outcome was a change in the skin perfusion pressure (SPP) after treatment with LA, and the secondary outcomes were changes in the viscosity-related laboratory parameters. RESULTS The wound-healing rate was 68.4%. The SPP at 2-3 weeks after series of LA were significantly higher both in the dorsal (41 vs. 53 mmHg, p = 0.037) and plantar (50.0 vs. 61.0 mmHg, p = 0.018) sides, compared to those at baseline. The viscosity-related laboratory markers were also significantly improved after the treatment; low-density lipoprotein-cholesterol (57.0 vs. 43.0 mg/dL, p = 0.002), fibrinogen (333 vs. 258 mg/dL, p < 0.001), and C-reactive protein (0.99 vs. 0.42 mg/dL, p = 0.001). CONCLUSION The novel LA significantly increased the SPP and improved relevant laboratory findings.

Abstract
Objectives: Rheocarna® therapy has recently been reported to improve peripherally measured blood flow as an adjuvant treatment after revascularization in patients with chronic limb-threatening ischemia. We investigated whether skin perfusion pressure and continuous walking distance were improved by performing Rheocarna® therapy after distal bypass surgery. Methods: This study included 10 patients who underwent Rheocarna® therapy after distal bypass surgery between June 2022 and March 2023. Rheocarna® therapy was performed five times after distal bypass surgery, and the skin perfusion pressure and continuous walking distance after distal bypass surgery were compared with those after Rheocarna® therapy. Results: The average age was 74.7 years, and nine patients (90%) were male. All patients were undergoing dialysis, with an average of 14.5 years of dialysis history. There were six patients (60%) with diabetes mellitus and five (50%) with hyperlipidemia. The ankle-brachial index was 0.62 ± 0.36 before distal bypass surgery and 0.936 ± 0.16 after Rheocarna® therapy, indicating a significant increase (p = 0.0117). Skin perfusion pressure dorsalis pedis was 71.5 ± 27.0 mmHg after Rheocarna® therapy, showing a marked increase from the preoperative value (p = 0.0020). Skin perfusion pressure planta pedis was 65.0 ± 26.3 mmHg after Rheocarna® therapy, which was a significant increase from the preoperative value (p = 0.0293). The continuous walking distance was 78.5 ± 102.7 m after the Rheocarna® therapy, which was a significant increase from the preoperative value (p = 0.0039). Conclusion: The skin perfusion pressure and continuous walking distance were significantly improved by Rheocarna® therapy after distal bypass surgery.

Abstract
As the number of patients affected by peripheral arterial disease continues to increase, new technical approaches and devices have been developed to provide effective and durable treatment options that will lead to improved outcomes. While the mainstay of endovascular intervention remains mostly balloon-based, several innovative techniques and technologies are in development that may provide new solutions. This review highlights recent endovascular advancements in the management of chronic limb-threatening ischemia and additional adjunctive devices that are needed to improve lesion patency, reduce the need for reintervention, and lead to better patient-centered functional outcomes.

Abstract
Limb amputation is a consequence, and the leading complication, of diabetic foot ulcers. Prevention depends on prompt diagnosis and management. Patients should be managed by multidisciplinary teams and efforts should be focused on limb salvage ("time is tissue"). The diabetic foot service should be organized in a way to meet the patient's clinical needs, with the diabetic foot centers at the highest level of this structure. Surgical management should be multimodal and include not only revascularization, but also surgical and biological debridement, minor amputations, and advanced wound therapy. Medical treatment, including an adequate antimicrobial therapy, has a key role in the eradication of infection and should be guided by microbiologists and infection disease physicians with special interest in bone infection. Input from diabetologists, radiologists, orthopedic teams (foot and ankle), orthotists, podiatrists, physiotherapists, and prosthetics, as well as psychological counseling, is required to make the service comprehensive. After the acute phase, a well-structured, pragmatic follow-up program is necessary to adequately manage the patients with the aim to detect earlier potential failures of the revascularization or antimicrobial therapy. Considering the cost and societal impact of diabetic foot problems, health care providers should provide resources to manage the burden of diabetic foot problems in the modern era.

Abstract
OBJECTIVES To assess wound healing after simultaneous endovascular treatment (EVT) and minor forefoot amputation and identify the predictors of delayed wound healing in patients with chronic limb-threatening ischemia (CLTI) and bacterial infections of the wounds. METHODS In this single-center retrospective cohort study, we evaluated 79 consecutive limbs with tissue loss from 73 CLTI patients who underwent simultaneous EVT and minor forefoot amputation between November 2017 and May 2020. To estimate the rate of wound healing after the simultaneous procedure, we used the Kaplan-Meier method. To assess the association between baseline characteristics and delayed wound healing, we used the Cox proportional hazard model. RESULTS All patients who underwent the simultaneous procedure had ischemic wounds with bacterial infection. The rate of wound healing at 6 months reached 82%. The median time for wound healing was 76 days. According to multivariable analysis, Lisfranc/Chopart amputation (hazard ratio (HR) 2.46, 95% confidence interval (CI) 1.09-6.60), absence of above-the-knee (ATK) occlusive lesions (HR 1.89, 95% CI 1.04-3.45), and poor below-the-ankle (BTA) runoff (HR 1.77, 95% CI 1.01-3.11) were independent predictors of delayed wound healing. CONCLUSION Lisfranc/Chopart amputation, absence of ATK occlusive lesions, and poor BTA runoff were independent predictors of delayed wound healing after simultaneous EVT and minor forefoot amputation in patients with CLTI and bacterial infections of the wound.

Abstract
AIM This study aimed to report injury precipitating tissue loss and to provide updated information on the time from tissue loss occurrence to referral to a vascular center for patients who developed chronic limb-threatening ischemia (CLTI) in Japan. METHODS We examined 450 patients who developed CLTI with tissue loss and were registered in a multicenter prospective study between October 2017 and June 2020. They were referred to the participating vascular centers for revascularization. Information on the injury precipitating tissue loss and time to referral was collected at registration. The severity of tissue loss was evaluated using the Wound, Ischemia, and foot Infection classification. RESULTS Injury precipitating tissue loss was absent in 52.0% (95% confidence interval, 47.3%-56.6%) of the patients. The absence was associated with lower albumin levels and preserved pressure sensation. Although the time to referral was significantly shorter in cases without a history of prereferral revascularization, 16.8% (12.8%-20.7%) of the patients were referred to the vascular centers more than 3 months after tissue loss occurrence. Time to referral, but not the lack of a clear precipitant for tissue loss, was significantly associated with the severity of tissue loss. CONCLUSION A clear precipitant for tissue loss was often lacking, particularly in patients with low albumin levels and preserved pressure sensation. Delayed referral to a vascular center is still common.

Abstract
Lower-limb peripheral arterial disease (PAD), is a common manifestation of systemic atherosclerosis, resulting from a partial or complete obstruction of at least one lower-limb arteries. PAD is a major endemic disease with an excess risk of major cardiovascular events and death. It also leads to disability, high rates of lower-limb adverse events and non-traumatic amputation. In patients with diabetes, PAD is particularly frequent and has a worse prognosis than in patients without diabetes. The risk factors of PAD are comparable to those for cardiovascular disease. The ankle-brachial index is usually recommended to screen PAD despite its limited performance in patients with diabetes, affected by the presence of peripheral neuropathy, medial arterial calcification, incompressible arteries and infection. Toe brachial index and toe pressure emerge as alternative screening tools. The management of PAD requires strict control of cardiovascular risk factors including diabetes, hypertension and dyslipidaemia, the use of antiplatelet agents and lifestyle management, to reduce cardiovascular adverse events, but few randomized controlled trials have evaluated the benefits of these treatments in PAD. Several advances have been achieved in endovascular and surgical revascularization procedures, with obvious improvement in PAD prognosis. Further studies are required to increase our understanding of the pathophysiology of PAD and to evaluate the interest of different therapeutic strategies in the occurrence and progression of PAD in patients with diabetes. Here, we present a narrative and contemporary review to synthesize the key epidemiology findings, screening and diagnosis methods, and major therapeutic advances regarding PAD in patients with diabetes.

Abstract
Background Percutaneous transluminal angioplasty (PTA) is widely used as a first-line revascularisation option in patients with chronic limb threatening ischemia (CLTI). This study aimed to evaluate the short-term endovascular revascularisation treatment outcomes of a cohort of Rutherford 6 (R6) CLTI patients, from a multi-ethnic Asian population in Singapore. Patients with R6 CLTI who underwent endovascular revascularisation from June 2019 to February 2020 at Singapore General Hospital, a tertiary vascular centre in Singapore, were included and followed up for one year. Primary outcome measures included number and type of reinterventions required, 3-, 6- and 12-month mortality, 6- and 12-month amputation free survival (AFS), wound healing success and changes in Rutherford staging after 3, 6 and 12 months. Results Two hundred fifty-five procedures were performed on 86 patients, of whom 78 (90.7%) were diabetics, 54 (62.8%) had coronary artery disease (CAD) and 54 (62.8%) had chronic kidney disease (CKD). 42 patients (48.8%) required reintervention within 6 months. Multivariate analysis revealed that the presence of CAD was a significant independent predictor for reintervention. Mortality was 15.1%, 20.9% and 33.7% at 3, 6 and 12 months respectively. AFS was 64.0% and 49.4% at 6 and 12 months. Inability to ambulate, congestive heart failure (CHF), dysrhythmia and CKD were significant independent predictors of lower 12-month AFS. Conclusions PTA for R6 CLTI patients was associated with relatively high mortality and reintervention rates at one year. CAD was an independent predictor of reintervention. More research is required to help risk stratify which CLTI patients would benefit from an endovascular-first approach versus conservative treatment or an immediate major lower extremity amputation policy.

Abstract
Bypass to the peroneal artery has sometimes been effective for pedal gangrene. However, the difficulty of approaching the terminal segment of the peroneal artery because of its anatomic features has been a clinical issue. Surgical access to this area can be achieved via a lateral approach with fibular resection. Although severe complications associated with fibular resection have rarely been reported, a less invasive surgical procedure would enable faster postoperative recovery and reduce the incidence of wound-related complications. We have described our experience with successful terminal peroneal artery bypass via a lateral approach without fibular resection in a 38-year-old male patient with chronic limb-threatening ischemia.

Abstract
IMPORTANCE The Bypass Versus Angioplasty for Severe Ischemia of the Leg randomized controlled trial showed comparable outcomes between endovascular revascularization (ER) and surgical revascularization (SR) for patients with critical limb ischemia (CLI). However, several observational studies showed mixed results. Most of these studies were conducted before advanced endovascular technologies were available. OBJECTIVE To compare ER and SR treatment strategies for 6-month outcomes among patients with CLI. DESIGN, SETTING, AND PARTICIPANTS This retrospective, population-based cohort study used the Nationwide Readmissions Database to identify 66 277 patients with CLI who underwent ER or SR from January 1, 2016, to December 31, 2018. Data analyses were conducted from January 1, 2022, to February 8, 2022. A propensity score with 1:1 matching was applied. Patients with CLI who underwent ER or SR were identified, and those with missing information on the length of stay and/or younger than 18 years were excluded. EXPOSURES Endovascular or surgical revascularization. MAIN OUTCOMES AND MEASURES The primary outcome was a major amputation at 6 months. Significant secondary outcomes were in-hospital and 6-month mortality and an in-hospital safety composite of acute kidney injury, major bleeding, and vascular complication. Subgroup analysis was conducted for major amputation in high-volume centers. RESULTS A total of 66 277 patients were identified between 2016 and 2018 who underwent ER or SR for CLI. The Nationwide Readmissions Database does not provide racial and ethnic categories. The mean (SD) age of the cohort was 69.3 (12) years, and 62.5% of patients were male. A total of 54 546 patients (82.3%) underwent ER and 11 731 (17.7%) underwent SR. After propensity score matching, 11 106 matched pairs were found. Endovascular revascularization was associated with an 18% higher risk of major amputation compared with SR (997 of 10 090 [9.9%] vs 869 of 10 318 [8.4%]; hazard ratio, 1.18; 95% CI, 1.08-1.29; P = .001). However, no difference was observed in major amputation risk when both procedures were performed in high-volume centers. Endovascular revascularization and SR had similar mortality rates (517 of 11 106 [4.7%] vs 490 of 11 106 [4.4%]; hazard ratio, 1.06; 95% CI, 0.93-1.20; P = .39). However, the ER group had a 17% lower risk of in-hospital safety outcomes compared with the SR group (2584 of 11 106 [23.3%] vs 2979 of 11 106 [26.8%]; odds ratio, 0.83; 95% CI, 0.78-0.88; P < .001). CONCLUSIONS AND RELEVANCE The results of this study suggest that ER was safer, without any difference in mortality, but ER was associated with an increased risk of major amputation compared with SR. However, the risk of major amputation was similar when both procedures were performed at high-volume centers.

Abstract
Objective: In this study, we aim to evaluate the efficacy of early closed toe amputation on the wound management of toe ulcers with suspected osteomyelitis after revascularization for chronic limb-threatening ischemia (CLTI). Methods: This retrospective study included patients who have underwent revascularization for toe ulcers associated with CLTI at Shizuoka Red Cross Hospital from 2015 to 2021. Wound management comprised early closed toe amputation for toe ulcers with suspected osteomyelitis (19 toes in 17 patients) or conservative treatment (35 toes in 26 patients). The primary endpoint was wound healing after revascularization. We compared the wound healing rate at 90 days and median healing time of early closed toe amputation versus conservative treatment. Results: Compared with the conservative treatment, early closed toe amputation was able to achieve a better wound healing rate at 90 days (89.5% vs. 68.6%; P<0.01) and a shorter median healing time (19 days vs. 62 days; P=0.01). Conclusion: There remains no established wound management for toe lesions associated with CLTI. Despite its several disadvantages including wound infection and possible foot deformity, early closed toe amputation for toe ulcers with suspected osteomyelitis can be considered a safe approach in terms of wound management.

Abstract
Background: Current assessment standards in chronic limb-threatening ischemia (CLTI) focus on macrovascular function while neglecting the microcirculation. Multispectral near-infrared spectroscopy (NIRS) provides hemodynamic characteristics of the microcirculation (i.e., capillaries) and may be a powerful tool for monitoring CLTI and preventing extremity loss. The aims of this study were to (1) investigate the effects of lower limb revascularization on the microcirculation and (2) determine if macrovascular and microvascular assessments correlate. Methods: An observational, retrospective cohort study of 38 endovascular interventions in 30 CLTI subjects was analyzed pre- and post-intervention for arterial Doppler acceleration times (AcT; macrovascular) and NIRS metrics (microvascular). Pre-intervention ankle-brachial index (ABI) was also analyzed. Results: AcT significantly decreased (p = 0.009) while oxyhemoglobin (HbO) significantly increased (p < 0.04) after endovascular intervention, indicating treatment efficacy. However, macrovascular measurements (ABI, AcT) and NIRS metrics of oxygenation and perfusion did not correlate (p > 0.06, r2 < 0.15, n = 23) indicating that macro- and microvascular assessment are not congruent. Conclusion: These findings suggest that macrovascular and microvascular assessments can determine interventional efficacy in their corresponding vasculature. Their lack of correlation, however, suggests the need for simultaneous assessment as independent use may cause diagnostic information to be missed.

Abstract
BACKGROUND Zinc (Zn) has been reported to play an important role in wound healing (WH). Nevertheless, the effect of Zn in chronic limb-threatening ischemia (CLTI) patients is unclear. This study investigated the effect of Zn on the clinical outcomes of CLTI patients undergoing bypass surgery.Methods and Results:This study reviewed 111 consecutive patients who underwent an infrainguinal bypass from 2012 to 2020. Patients with Zn deficiency (serum Zn level <60 μg/dL) received oral Zn supplementation and maintained a normal level until WH. This study aimed to explore: (1) the effect of Zn deficiency; and (2) Zn supplementation in Zn-deficient patients on the clinical outcomes of this cohort. Patients with Zn deficiency, Zn supplementation, and no Zn supplementation despite Zn deficiency accounted for 48, 21, and 42 patients, respectively. (1) Zn deficiency was associated with WH (HR, 0.47; 95% CI, 0.29-0.78: P=0.003), major adverse limb events (MALE) (HR, 2.53; 95% CI, 1.26-5.09: P=0.009), and major amputation or death (HR, 3.17; 95% CI, 1.51-6.63: P=0.002). (2) Zn supplementation was positively related to WH (HR, 2.30; 95% CI, 1.21-4.34: P=0.011). This result was confirmed using propensity score matching (HR, 2.24; 95% CI, 1.02-4.87: P=0.043). CONCLUSIONS The current study revealed that Zn level was associated with clinical outcomes in CLTI patients after bypass surgery. Oral Zn supplementation could improve WH in these patients.

OBJECTIVE Inframalleolar (IM) bypass has been reported to demonstrate acceptable patency and limb salvage in chronic limb-threatening ischemia (CLTI) patients. However, wound healing after IM bypass and comparisons between pedal artery (PA) bypass and pedal branch artery (PBA) bypass are lacking. METHODS We reviewed prospectively collected data from 208 consecutive patients after IM bypass performed over a period of six years. Patients were divided into two groups based on the distal anastomotic artery: the PA group (dorsal pedis artery or common plantar artery) and the PBA group (medial tarsal, lateral tarsal, medial plantar, and lateral plantar artery). The primary outcome was wound healing, and secondary outcomes included loss of patency and limb and life prognosis. RESULTS Of the 208 patients, 174 (74%) had PA bypass, whereas 34 (16%) had PBA bypass. Patients in the PBA group were significantly younger than those in the PA group (69 ± 7 vs. 73 ± 9, P = .03). Although early (30-day) graft failure was more common in the PBA group, late clinical outcomes, including the wound healing rate (79% in the PA group and 84% in the PBA group, P=.74), were similar between the two groups. The Global Limb Anatomic Staging System (GLASS) IM grade (HR, 0.73; 95% confidence interval [CI], 0.58-0.93: P=.006); wound, ischemia, and foot infection (WIfI) wound grade (HR, 0.67; 95% CI, 0.51-0.89: P<.01); and WIfI foot infection grade (HR, 0.79; 95% CI, 0.65-0.96: P=.02) were independent predictors of wound healing. CONCLUSIONS The current study revealed that wound healing in patients following PBA bypass was acceptable and comparable to that following PA bypass. In the modern era, including high prevalence of infrapopliteal angioplasty, our results could provide useful information to clinicians in actual clinical settings. Moreover, PBA bypass may be an alternative revascularization procedure to avoid major amputation when the pedal artery is occluded, such as in the GVG IM P2 grade. Prospective multicenter larger studies are warranted to confirm the findings of this study and to compare PBA bypass and IM EVT in anatomical "no-option" CLTI.

Abstract
Objective: The perfusion index (PI) is a physiological marker for evaluating the peripheral circulation. We explored the possibility of using PI as a screening tool for development of critical limb ischemia in peripheral artery disease (PAD). Method: We measured the PI in 79 limbs of 70 PAD patients. Data were analyzed to find a correlation between the PI and PAD severity. Result: The PI tended to be lower as PAD became severer. Especially, there were significant differences between the Fontaine 1 and Fontaine 4 groups in average PI and minimum PI, and between Fontaine 1 and two other groups (Fontaine 2 and Fontaine 4 groups) in maximum PI. A mild correlation was found between PI and the ankle brachial index. These data were used to calculate an average PI of 0.27 as a cut-off value for critical limb ischemia (CLI). In 65 asymptomatic PAD patients and claudication, significantly more patients with a PI value greater than the cut-off value developed CLI than those with a PI lower than the cut-off. Conclusion: The PI can be a useful tool for evaluating the development of CLI in mild PAD patients, and patients tended not to progress to CLI when their average PI was higher than 0.27.

Skin Perfusion Pressure Predicts Early Wound Healing After Endovascular Therapy in Chronic Limb Threatening Ischaemia. Eur J Vasc Endovasc Surg 2021; 62:909-917. [PMID: 34690070 DOI: 10.1016/j.ejvs.2021.08.030] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2021] [Revised: 07/12/2021] [Accepted: 08/26/2021] [Indexed: 12/13/2022]
Abstract
OBJECTIVE Skin perfusion pressure (SPP) has been proposed as a method to predict wound healing in chronic limb threatening ischaemia (CLTI). However, studies regarding the impact of SPP before and after endovascular therapy (EVT) on wound healing are limited. This study sought to evaluate the predictive value of SPP for early wound healing in CLTI treated by EVT. METHODS Between January 2018 and June 2020, 236 limbs (172 patients) with CLTI that underwent SPP measurement before and after EVT were included. SPP was measured before and 24 - 48 hours after the procedure. Early wound healing was defined as the achievement of complete epithelisation of all wounds without major amputation within three months of EVT. RESULTS Early wound healing was achieved in 145 (61.4%) limbs after EVT. Baseline SPP (44.1 ± 21.0 mmHg vs. 33.5 ± 21.7 mmHg; p < .001) and post-procedural SPP (61.8 ± 18.5 mmHg vs. 37.4 ± 19.9 mmHg; p < .001) were significantly higher in the wound healing (+) group than in the wound non-healing (-) group. The area under the receiver operating characteristics curve for early wound healing was 0.82 for post-procedural SPP with a cutoff value of 50 mmHg (sensitivity 74.5%, specificity 78.0%). The early wound healing rate was significantly higher with a post-procedural SPP ≥ 50 mmHg compared with a SPP < 50 mmHg (84.4% vs. 35.0%; p < .001). CONCLUSION Post-procedural SPP with a cutoff value of 50 mmHg was capable of predicting early wound healing after EVT in CLTI.

Impact of Controlling a Nutritional Status Score on Wound Healing in Patients with Chronic Limb-Threatening Ischemia after Endovascular Treatment. Nutrients 2021; 13:nu13113710. [PMID: 34835966 PMCID: PMC8625291 DOI: 10.3390/nu13113710] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Revised: 10/14/2021] [Accepted: 10/19/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Chronic limb-threatening ischemia (CLTI) is the most advanced stage of peripheral artery disease. Therefore, a multidisciplinary approach is necessary to avoid major amputation in CLTI patients. Malnutrition worsens the condition of CLTI patients, and therefore, it may be important to evaluate the nutritional status in patients with CLTI. This study was designed to evaluate the baseline patient characteristics and the influence of the controlling nutritional status (CONUT) score on the clinical results. Method and Results: A retrospective, single-center, non-randomized study was conducted to evaluate the associations of death, major amputation, and wound healing rate at 12 months with the CONUT score on admission. Consecutive CLTI patients (mean age 73.2 ± 10.4 years; 84 males) who underwent endovascular therapy (EVT) for infra-popliteal lesions at Fukuoka University Hospital from January 2014 to May 2019 were enrolled and divided into two groups (higher and lower CONUT score groups). The higher CONUT group showed a higher percentage of dialysis (66.7% vs. 33.9%, p < 0.001) and a higher clinical frailty scale (5.9 ± 1.4 vs. 4.9 ± 1.9, p = 0.005) than the lower CONUT group. Rates of amputation-free survival were 89.5% and 69.8% in the lower and higher CONUT groups, respectively. In addition, rates of wound healing at 12 months were 98.0% and 78.3% in the lower and higher CONUT groups, respectively. Multivariate regression analysis demonstrated that a higher CONUT score was an independent predictor for delayed wound healing (OR: 11.2; 95% CI: 1.29–97.5; p = 0.028). Conclusion: An assessment of the nutritional status using the CONUT score could be useful for predicting wound healing, and earlier nutritional intervention may improve the outcome of CLTI patients. Early examination and treatment, along with raising awareness of the issue, may be important for improving the prognosis.

Abstract
OBJECTIVE The purpose of this study was to evaluate the influence of inframalleolar disease (Global Limb Anatomic Staging System Inframalleolar [GLASS IM] modifier) on long term outcomes of patients with chronic limb threatening ischaemia (CLTI) after distal bypass. METHODS Patients who underwent distal bypass for CLTI from January 2012 to December 2019 at a single centre were reviewed retrospectively. Comparisons including baseline characteristics, procedural details, and long term outcomes were made between patients with an intact pedal arch (GLASS IM modifier P0), an absent or severely diseased pedal arch (P1), and no target artery crossing the ankle into the foot (P2), diagnosed by pre- and intra-operative high quality angiography. The primary endpoint was limb salvage. The secondary endpoints were graft patency and wound healing. RESULTS A total of 254 distal bypasses were performed in 206 patients (139 males; median age, 76 years). The GLASS IM modifier was P0 in 80 (32%) limbs, P1 in 127 (50%), and P2 in 47 (18%). During the follow up period, 22 limbs (9%) required major amputation. The limb salvage rates at three years in P0, P1, and P2 cases were 94%, 89%, and 93%, respectively, with no significant differences among the modifiers. The primary patencies at three years in P0, P1, and P2 cases were 49%, 38% and 24%, respectively. The primary patency in P2 cases was significantly lower than that in P0 cases (p < .050). The respective wound healing rates at 12 months were 97%, 93%, and 79%, and again the wound healing rate in P2 cases was significantly lower than those in other cases (p < .050). CONCLUSION Long term outcomes including patency, limb salvage, and wound healing after distal bypass for CLTI patients with an infrapopliteal lesion were acceptable in cases in each GLASS IM modifier.

Abstract
BACKGROUND Almost 38% of all patients with end-stage chronic kidney disease (CKD) have peripheral arterial disease of the lower limbs that can lead to chronic limb threatening ischemia (CLTI). The aim of this study was to assess the impact of several factors to conduct a stratification of the amputation risk in CKD patients with CLTI receiving endovascular revascularization. METHODS Observational, retrospective, single-center study of patients treated from 2010 to 2016. The primary endpoint was the major amputation. The study included adult CKD dialysis patients affected by CLTI (rest pain and/or trophic lesions) with indication to endovascular revascularization and excluded for open repair. RESULTS A total of 82 patients were considered (58 men [70.7%], 24 women [29.3%] mean age 70.4±15.0 years). The number of major amputations was 28 (34.1%). The arterial lesion severity (TASC II-classification) and the trophic lesions extension (WIfI classification) were significantly associated with major amputation (OR and 95%CI, 1.20 [1.07-1.34], P=0.001; 2.65 [1.49-4.72], P=0.001; respectively). Based on the above-mentioned characteristics, a prognostic score was proposed to predict the major amputation risk. A score ≥23 was associated with a 67.6% probability of amputation in the following 12 months. CONCLUSIONS The CLTI revascularization is associated with poor outcomes in CKD patients. The present clinical score provided a pragmatic tool to calculate the major amputation risk. An elevated score could facilitate the decision-making process in order to perform an endovascular treatment vs. conservative approach.

Abstract
OBJECTIVES The aim of this study was to determine the relationship between preoperative nutritional status and wound healing in patients undergoing surgical reconstruction for ischemic tissue loss. METHODS The preoperative nutritional status of patients who underwent surgical reconstruction for ischemic tissue loss for the years 2011-2018 was retrospectively estimated using the Controlling Nutritional Status (CONUT) score. Patients were allocated to two groups: Group I, normal nutrition or mild malnutrition (CONUT score ≤4), and Group II, moderate-to-severe malnutrition (CONUT score ≥5). Wound healing was set as the primary endpoint and major amputation and death as the secondary endpoints. The wound healing, limb salvage, and overall survival rates were calculated after two years using the Kaplan-Meier method, and Cox proportional hazards regression analysis was performed to determine which variables were independently associated with these outcomes. RESULTS Forty-eight patients with missing values for the CONUT score were excluded. A total of 174 limbs in 147 patients were studied (Group I: 115 limbs in 100 patients; Group II: 59 limbs in 47 patients). The mean duration of the study was 519 ± 270 days. The Kaplan-Meier curves showed that wound healing in Group I was superior to that in Group II (Group I vs. II: two-year wound healing, 97% vs. 79%; time to 50% wound healing, 83 vs. 150 days, p < 0.001), and multivariate analysis showed that the CONUT score was an independent predictor of wound healing (hazard ratio, 0.63; 95% confidence interval, 0.41-0.98; p = 0.038). CONCLUSIONS Patients with better preoperative nutritional status are more likely to experience wound healing earlier than those with excessive malnutrition.

Abstract
BACKGROUND/OBJECTIVE This study's goal is to describe wound outcomes at 2 years following intervention for atherosclerotic femoropopliteal lesions in patients with ischemic tissue loss. METHODS A retrospective review of 135 first-time endovascular procedures for chronic femoropopliteal atherosclerotic lesions related to ischemic tissue loss was performed. The final wound outcomes were categorized according to the initial wound healing, recurrence and the need of major/minor amputation. RESULTS At 2-years of follow up, 76 limbs (56.3%) showed complete wound healing without recurrence, however, wound development occurred at other sites on the same foot following complete primary healing in 11 limbs (8.1%). Tolerable wounds persisted or wounds recurred at the same site in 30 limbs (22.2%), and 18 limbs (13.3%) needed major amputations. Independent factors that prevented wound healing without recurrence at 2 years were renal insufficiency (HR = 0.225, 95% C.I. = 0.091-0.556, p = 0.001), ankle pressure < 50 mmHg or flat forefoot PVR (HR = 0.328, 95% C.I. = 0.124-0.867, p = 0.025) and functional performance < 4 metabolic equivalents (MET) (HR = 0.150, 95% C.I. = 0.063-0.360, p < 0.001). CONCLUSION Wound outcome classifications showed detailed information regarding clinical outcomes in patients with ischemic tissue loss. Renal insufficiency, ischemia grade 3 and poor functional performance were independent risk factors that prevented wound healing.

Abstract
Recently, Society for Vascular Surgery guideline recommends evaluating anatomic pattern with use of Global Limb Anatomic Staging System (GLASS) in Chronic Limb-Threatening Ischemia (CLTI) patients. The aim of this study is to validate GLASS stage into CLTI patients on hemodialysis (HD) and investigate the impact of GLASS stage to wound healing and amputation-free survival (AFS). Between April 2009 and March 2018, we performed EVT for 154 limbs in CLTI patients on HD. GLASS was defined as femoropopliteal (FP) and infrapopliteal (IP) segments separately graded (0-4), then combined into three GLASS stages for the limb (I-III). We divided them into three GLASS stages with using this system. We compared the clinical outcomes between three groups (GLASS I, GLASS II, and GLASS III). Patient characteristics were almost similar between the three groups. Lesion characteristics was more complex and the rate of success was lower in GLASS III. Cox regression multivariate analysis revealed that diabetes mellitus (HR 2.4, 95% CI 1.37-4.01, p < 0.01) and WIfI high (HR 2.3, 95% CI 1.04-6.01, p = 0.04) were the predictors of non-wound healing, whereas age (HR 1.6, 95% CI 1.09-2.29, p = 0.01), WIfI clinical stage 4 (HR 2.4, 95% CI 1.30-4.36, p < 0.01), and non-ambulatory status (HR 2.0, 95% CI 1.17-3.29, p = 0.01) were the predictors of AFS. GLASS stage in CLTI patient on HD could not predict wound healing, and AFS in this study.

Abstract
A 74-year-old man with diabetes and end-stage renal failure on regular dialysis required revascularization for gangrene of multiple toes and a heel ulcer on the right foot with chronic limb-threatening ischemia. However, the anterior tibial artery, posterior tibial artery, and peroneal artery, which are the usual targets below the knee, showed obstruction or calcification and were considered inappropriate bypass targets. Instead, a collateral artery developed along the area of the posterior tibial artery, and bypass surgery was performed with this artery. This is a case report showing successful collateral artery bypass grafting in the distal infrapopliteal segment.

Abstract
OBJECTIVES The purpose of this study was to evaluate the results of combining superficial femoral artery endovascular therapy with distal bypass originating from the popliteal artery as a method of lower extremity revascularization in patients with chronic limb-threatening ischemia. METHODS The records of patients undergoing combined superficial femoral artery endovascular therapy with popliteal-to-distal bypass for chronic limb-threatening ischemia from January 2014 to April 2020 at a single institution were retrospectively reviewed. The patients' background, operative details, and long-term outcomes were analyzed. RESULTS Fifty-two popliteal-to-distal bypasses with superficial femoral artery endovascular therapy were performed in 49 patients (33 men; mean age, 76 ± 9 years; diabetes mellitus, 80%; end-stage renal disease with hemodialysis, 47%). The Trans-Atlantic Inter-Society Consensus II classification of superficial femoral artery-popliteal lesion was "A" in 8 (15%) patients, "B" in 14 (27%) patients, "C" in 24 (46%) patients, and "D" in 6 (12%) patients. The intervention for superficial femoral artery lesions was plain old balloon angioplasty in 4 patients, self-expandable nitinol stent in 15 patients, drug-coated balloon in 18 patients, drug-eluting stent in 4 patients, stent graft in 10 patients, and interwoven nitinol stent in 1 patient. Distal bypass originated from the above-knee popliteal artery in 9 (17%) limbs and the below-knee popliteal artery in 43 (83%) limbs. The most common outflow artery was the posterior tibial artery (44%). The mean follow-up period was 17 ± 17 months. The primary and secondary patency of the graft was 44% and 72%, respectively, at 1 year and 39% and 72%, respectively, at 3 years. Primary patency and freedom from clinical-driven target lesion revascularization of superficial femoral artery endovascular therapy lesions were 85% and 90%, respectively, at 1 year and 63% and 75%, respectively, at 3 years. Limb salvage was 97% at 1 year and 92% at 3 years. Wound healing was 67% at 6 months and 83% at 12 months. CONCLUSIONS Combined superficial femoral artery endovascular therapy with popliteal-to-distal bypass may be a promising approach for patients with chronic limb-threatening ischemia because of durable patency, acceptable wound healing, and good limb salvage.

Abstract
Objective: In paramalleolar bypass for critical limb-threatening ischemia (CLTI), excessive skin tension may occur for the closure of surgical wounds around the ankle. Furthermore, these surgical incisions are often proximal to infectious ischemic ulcers. Wound dehiscence caused by skin tension and surgical site infection carries a risk of graft exposure, anastomotic disruption, or graft insufficiency. Patients and Methods: Tension-free wound management was adopted in eight patients who underwent paramalleolar bypass for CLTI. Tension-free closure was adopted for surgical incisions for distal anastomotic site of the paramalleolar bypass, whereas the incisions for saphenous vein harvest were left open. A relief incision was made as needed. The opened incisions were covered with artificial dermis. Results: All surgical incisions and ischemic wounds healed successfully within 1.8 months after bypass. Two postoperative graft stenoses occurred, which were rescued by additional endovascular intervention. Secondary graft patency, wound healing, and limb salvage rates were 100% during an average follow-up period of 30 months. Conclusion: Tension-free wound closure using artificial dermis was effective in selected cases of paramalleolar bypass for CLTI.

Abstract
Introduction: The use of matching techniques in observational studies has been increasing and is not always used appropriately. Clinical experiments are not always feasible in critical patients with renal outcomes, and observational studies are an important alternative.
Objective: Through a scoping review, determine the available evidence on the use of matching methods in studies involving critically ill patients and assessing renal outcomes.
Methods: Medline, Embase, and Cochrane databases were used to identify articles published between 1992 and 2020 up to week 10, which studied different exposures in the critically ill patient with renal outcomes and used propensity matching methods.
Results: Most publications are cohort studies 94 (94. 9 %), five studies (5. 1 %) were cross-sectional. The main pharmacological intervention was the use of antibiotics in seven studies (7. 1%) and the main risk factor studied was renal injury prior to ICU admission in 10 studies (10. 1%). The balance between the baseline characteristics assessed by standardized means, in only 28 studies (28. 2%). Most studies 95 (96 %) used logistic regression to calculate the propensity index.
Conclusion: Major inconsistencies were observed in the use of methods and in the reporting of findings. A summary is made of the aspects to be considered in the use of the methods and reporting of the findings with the matching by propensity index.

Abstract
In the last 15 years an abundance of literature has demonstrated that angiosome-targeted revascularization, either endovascular or open, can lead to better clinical results in patients with chronic limb-threatening ischemia. According to this literature, the angiosome concept should guide our treatment strategy in every chronic limb-threatening ischemia patient. However, in our daily practice, its application is often difficult or impossible. Most foot wounds spread over multiple angiosomes and, moreover, the value of an angiosome-guided revascularization approach can vary according to vascular anatomy, collateral vessel network, type of revascularization, and wound. The aim of this article is to explore values and limits of the angiosome concept, and to propose some “instructions for use” regarding its application in our daily practice.

Abstract
Ischaemic diabetic heel ulcers are difficult to treat and prognosis is often guarded. The aim was to document our outcome of treating heel ulcers following revascularization in a predominantly diabetic Asian cohort presenting with chronic limb threatening ischaemia from Singapore. Retrospective cohort study (n = 66, 66 limbs) over a 5‐year period. Data were collected from hospital electronic health records. Outcomes included time to healing, amputation free survival (AFS), and mortality. Minimum follow‐up period was 6 months. Multivariate regression analysis was performed to look for factors associated with poor outcome. Mean age was 67.4 ± 8.8 years. 62/66 (93.9%) were diabetics. Mean wound size at presentation was 3.6 ± 2.3 cm. Mean Wound, Ischaemia, Foot Infection (WIFI) score was 5 ± 1.6. 12/66 (18%) patients had a patent posterior tibial artery pre‐operatively. Straight line flow was restored in only 31/66 (46.9) patients but 47/66 (71.2%) had successful limb salvage. Median time to wound healing was 90.0 (IQR 60‐180) days. A median of 1 (IQR 0‐2) wound debridement was required. Patients who underwent negative pressure dressing (23/66; 34.8%) required a median of 26 (IQR 13‐33) cycles to achieve healing. Amputation free survival (AFS) was 72% and 68% at 6‐ and 12‐months, respectively. Mortality rate was 16.7% and 19.7% at 6‐ and 12‐months, respectively. Low albumin level and initial Rutherford class were independent predictors of worse 6‐month AFS. Outcomes of heel ulcers post revascularisation may not be as poor as previously described. Persistent attention to wound care with multidisciplinary effort is needed for optimal healing.

Abstract
OBJECTIVE The objective of this study was to determine whether the angiosome concept and WIfI classification in patients undergoing endovascular treatment is associated with the limb salvage rate and wound healing rate in patients with critical limb ischemia(CLI). METHODS This was a retrospective, consecutive cohort study of CLI patients who underwent infrapopliteal angioplasty at the Vascular and Endovascular Surgery Service of the Hospital do Servidor Público Estadual, São Paulo, between January 2013 and January 2019. The primary outcome variable was the limb salvage rate and wound healing rate. The secondary outcome variables were patency, survival, time free from reintervention, and operative mortality rate. RESULTS Overall, 95 infrapopliteal endovascular procedures were performed in 95 patients. The initial technical success rate was 100%. The mean ± standard deviation outpatient follow-up time was 775 ± 107.5 days. The analyses were performed at 360 days for wound healing rate and 720 days for limb salvage rates, overall survival, and time freedom from reintervention. According to the angiosome concept, there were 54 patients (56.8%) classified in the direct group and 41 patients (43.2%) in the indirect group. Regarding the WIfI classification subanalysis, there were 22 patients WIfI 0-1 (23.2%) and 73 patients WIfI 2-3 (76.8%). Furthermore, the indirect group had a higher ulcer healing rate than the direct group; however, it was not statistically significant (82.9%; 66.7%%, respectively, P = 0.059). However, the time to heal the ulcer was faster in the WIfI 0-1 groups than WIfI 2-3 groups (164.82 days versus 251,48; P = 0.017). The limb salvage rates at 720 days were similar among indirect and direct Groups (92.6% and 85.4%, P = 0.79). Likewise, the freedom from reintervention rates at 720 days were also similar in Indirect and direct groups (74.6% and 64%, P = 0.23). The survival rates at 720 days were similar in both indirect and direct groups (86.8 and 85.6%, respectively; P = 0.82). The amputation free survival rate at 720 days by the Kaplan-Meier method was 91.3% in the indirect group and 85.9% in the direct group, but with no statistical significance between the groups (P = 0.37) CONCLUSIONS: This study concluded that, in endovascular treatment, the angiosome concept is no longer important to limb salvage rates, nor ulcer/wound healing rates. Moreover, the WIfI classification 0-1 is associated with faster and higher wound/ulcer healing rates than WIfI classification 2-3.

Predictive Model for Postoperative Ambulatory Function after Lower Extremity Bypass in Chronic Limb-Threatening Ischemia. Ann Vasc Surg 2020; 71:321-330. [PMID: 32768542 DOI: 10.1016/j.avsg.2020.07.033] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 06/29/2020] [Accepted: 07/08/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND In chronic limb-threatening ischemia, maintenance or recovery of ambulatory function is an important goal of treatment. This study aimed to develop a predictive model for ambulatory ability 1 year after bypass based on preoperative risk factors, including the Wound, Ischemia, and foot Infection (WIfI) classification. METHODS We analyzed 146 patients with chronic limb-threatening ischemia (154 limbs) who underwent bypass to below the knee arteries. The patients were classified into 2 groups based on ambulatory status 1 year postoperatively: postoperative ambulation (99 patients, 104 limbs) and postoperative nonambulation (47 patients, 50 limbs). Various factors associated with postoperative ambulation were analyzed and a predictive model of postoperative ambulation was developed. RESULTS Multivariate logistic regression analysis detected preoperative nonambulatory status, functional nonindependence in daily living, older age, WIfI wound grade 3, chronic obstructive pulmonary disease, and hemodialysis as independent risk factors for postoperative nonambulation. The predictive scoring model (scores ranging from -5.0 to 4.4) comprising these risk factors discriminated the postoperative ambulatory status well: the probabilities of postoperative ambulatory ability were ≥85% in those with a score ≤-2, 50% in those with a score of zero, and ≤15% in those with a score ≥2. The area under the receiver operating characteristic curve was 0.898, indicating good performance of the model. CONCLUSIONS Preoperative nonambulatory status, functional nonindependence, advanced age, high WIfI wound grade, chronic obstructive pulmonary disease, and hemodialysis were important predictors of postoperative nonambulatory status. The predictive model will help us identify patients who will benefit from bypass surgery.

Abstract
Objective To determine the predictive factors of postoperative hospital stay and total hospital medical cost among patients who underwent total laryngectomy. Methods A total of 213 patients who underwent total laryngectomy in a tertiary referral center for tumor ablation were enrolled retrospectively between January 2009 and May 2018. Statistical analyses including Pearson's chi-squared test were used to determine whether there was a significant difference between each selected clinical factors and outcomes. The outcomes of interest including postoperative length of hospital stay and inpatient total medical cost. Logistic regression analyses were performed to reveal the relationship between clinical factors and postoperative length of hospital stay or total inpatient medical cost. Results Preoperative radiotherapy (p = 0.007), method of wound closure (p < 0.001), postoperative serum albumin level (p = 0.025), and postoperative serum hemoglobin level (p = 0.04) were significantly associated with postoperative hospital stay in univariate analysis. Postoperative hypoalbuminemia (odds ratio [OR]: 2.477; 95% confidence interval [CI]: 1.189–5.163; p = 0.015) and previous radiotherapy history (OR 2.194; 95% CI: 1.228–3.917; p = 0.008) are independent predictors of a longer postoperative hospital stay in multiple regression analysis. With respect to total inpatient medical cost, method of wound closure (p < 0.001), preoperative serum albumin level (p = 0.04), postoperative serum albumin level (p < 0.001), and history of liver cirrhosis (p = 0.037) were significantly associated with total inpatient medical cost in univariate analysis. Postoperative hypoalbuminemia (OR: 6.671; 95% CI: 1.927–23.093; p = 0.003) and microvascular free flap reconstruction (OR: 5.011; 95% CI: 1.657–15.156; p = 0.004) were independent predictors of a higher total inpatient medical cost in multiple regression analysis. Conclusions Postoperative albumin status is a significant factor in predicting prolonged postoperative hospital stay and higher inpatient medical cost among patients who undergo total laryngectomy. In this cohort, the inpatient medical cost was 48% higher and length of stay after surgery was 35% longer among hypoalbuminemia patients.

Abstract
Although several studies showed that angiosome-guided endovascular treatment improved wound healing and major amputation rates in patients with chronic limb-threatening ischemia (CLTI), effectiveness of the angiosome concept to the treatment of ischemic foot remains to be elucidated, especially in bypass surgery. Arterial anatomy of the foot and ankle shows that there are multiple supplementary circulation including arterial–arterial connections and choke nexus, which indicates angiosome concept may carry limited importance in bypass surgery for CLTI. On the other hand, patients with diabetes or renal dysfunction have partial occlusion of arterial–arterial connections and, therefore, quite a few patients with CLTI in Japan may present with limited but impaired supplementary circulation around the ankle. This article reviews the arterial anatomy and circulation of the foot and ankle and discusses availability and limitations of angiosome-guided bypass surgery.

Abstract
Objective: Clinical guidelines have long recommended referring patients with clerical limb ischemia (CLI) to a vascular specialist early in the course of their disease to plan for revascularization options. However, no data were so far available on how promptly CLI patients were referred to a vascular center in the real-world settings in Japan. This study aimed to survey the duration from wound occurrence to referral to a vascular center in CLI patients in Japan. Materials and Methods: We analyzed a database of a prospective, multicenter registry in Japan, including 428 CLI patients presenting ischemic wounds and referred to vascular centers. The duration of the wound occurrence was surveyed at registration. Results: The wound duration exceeded 1 month in 58.2% [95% confidence interval: 53.2% to 63.1%] of the patients, and 3 months (i.e., one season) in 15.9% [12.4% to 19.4%]. No clinical features were significantly associated with the wound duration. The wound duration was independently associated with the wound severity evaluated using the Wound, Ischemia, and foot Infection classification system (P=0.030). Conclusion: A substantial number of CLI patients referred to vascular centers had a long duration of wounds, i.e., time from wound occurrence to the referral.
