Poor Below Knee Runoff Impacts Femoropopliteal Stent Failure and Fluoropolymer Antithrombotic Effect in Healthy Swine Model. Eur J Vasc Endovasc Surg 2023; 66:722-729. [PMID: 37516380 DOI: 10.1016/j.ejvs.2023.07.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 06/20/2023] [Accepted: 07/21/2023] [Indexed: 07/31/2023]
Abstract
OBJECTIVE Poor below knee (BTK) runoff is a predictor of stent failure after endovascular femoropopliteal artery treatment; however, lack of pathological evaluation has prevented characterisation of stent failure. The study aimed to investigate the impact of poor BTK runoff and the antithrombotic effect of the polymer of fluoropolymer coated paclitaxel eluting stents (FP-PESs) in a healthy swine femoropopliteal artery model. METHODS FP-PESs and bare metal stents (BMSs) and FP-PES and polymer free paclitaxel coated stents (PF-PCSs) were implanted in the bilateral femoral arteries of healthy swine (n = 6, respectively) following coil embolisation in both tibial arteries to induce poor BTK runoff. Histological assessment and intravascular imaging device evaluation were performed at one month. The Japanese Association for Laboratory Animal Science approved the study protocol (reference number: IVT22-90). RESULTS Optical coherence tomography showed significantly lower percent area stenosis in FP-PES compared with BMS (37.3%, [interquartile range (IQR), 25.6 - 54.3] % vs. 92.5% [IQR, 75.5 - 96.1] %, respectively, p = .031), and PF-PCS (8.3% [IQR, 4.5 - 27.0] % vs. 31.2% [IQR, 23.3 - 52.2] %, respectively, p = .031). Histopathological evaluation demonstrated that thin fibrin attachment without re-stenosis was the most dominant neointimal tissue characteristic in FP-PES. On the other hand, neointimal tissue characteristics with significant restenosis of BMS and PF-PCS were mainly organising or organised thrombus. CONCLUSION Organising and or organised thrombus attachment due to poor BTK runoff was the main cause of in stent restenosis of the swine femoral artery. FP-PES demonstrated the least percent area stenosis, suggesting the importance of the antithrombotic effect of polymer.

Results of Excimer Laser Ablation Combined with Drug-Coated Balloon for Atherosclerotic Obliterans of Lower Extremity and Risk Factors for Loss of Primary Patency. Ann Vasc Surg 2023; 91:223-232. [PMID: 36584966 DOI: 10.1016/j.avsg.2022.11.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 11/12/2022] [Accepted: 11/24/2022] [Indexed: 12/29/2022]
Abstract
BACKGROUND The results of excimer laser ablation (ELA) combining with drug-coated balloon (DCB) in the treatment for atherosclerotic obliterans (ASO) remains unclear. METHODS Retrospectively enrolled patients who underwent ELA combined with DCB in 2 centers. The primary endpoint was primary patency, and secondary endpoints included technical success, procedure-related complications, major amputation, clinically driven target lesions reintervention (CD-TLR), measurements of ankle-brachial index (ABI), and quality of life (QoL). RESULTS 102 patients were enrolled. The primary patency was 86.7% (95% confidence interval [CI]: 72.9%-89.0%) at 12 months and 82.6% (95% CI: 78.2%-92.1%) at 24 months. The freedom from reintervention was 87.8% (95% CI: 79.5%-92.9%) at 12 months and 86.6% (95% CI: 78.1%-92.0%) at 24 months. The ABI measurement and QoL were significantly improved at each follow-up point. Sixteen (15.7%) patients lost the primary patency. Patients losing the primary patency demonstrated higher Rutherford class (P = 0.004), worse runoff (P < 0.001), higher Peripheral Arterial Calcium Scoring System (PACSS) (P < 0.001), and smaller ratio of tube diameter to reference vessel diameter (TD/RVD) (P < 0.001) compared with patients without losing it. The run-off ≥7 (adjusted odds ratio [aOR]: 34.3; 95% CI: 2.9-398.3; P = 0.005) and TD/RVD <4.9 (aOR: 24.7; 95% CI: 1.7-359.5; P = 0.019) were independent risk factors for loss of primary patency. CONCLUSIONS ELA combined with DCB seemed an effective and safe treatment for ASO of lower extremity, and it could not only reduce the implantation of stent but significantly improve QoL. The run-off ≥7 and TD/RVD <4.9 were independent risk factors for loss of primary patency.

Abstract
BACKGROUND Bifurcated vein grafts have been described in reconstructive microsurgery. No comparative studies have been published in lower limb arterial revascularization. The aim of this study was to compare non-reversed bifurcated vs. single vein graft in patients with critical limb-threatening ischemia (CLTI) undergoing lower limb distal bypass. METHODS Between January 2015 and December 2021 193 CLTI patients have been treated at our center with vein bypass, and distal anastomosis on infrapopliteal vessels; 137 patients (71%) received a single graft (Group SIN), and 56 patients (29%) had a bifurcated bypass (Group BIF). Primary outcomes measures were time to healing, primary patency, primary assisted patency, secondary patency, and limb salvage. Two-year outcomes according to Kaplan-Meier curves were evaluated and compared. RESULTS Both groups were homogeneous in terms of demographic data, preoperative risk factors, and clinical presentation except for an elderly age in Group BIF (77.5 vs. 71.5 years; P<0.001). Intraoperative technical success was achieved in all patients. Overall median duration of follow-up was 19 months (interquartile range 9-36). Wound healing did not differ between the two groups (77.4% Group SIN vs. 73.2% Group BIF; P=0.33). Mean time to healing was faster in Group BIF (2.4 vs. 6.8 months; P<0.001). At 2-year follow-up there were no differences between the two groups in terms of primary patency (71.4% Group SIN vs. 54% Group BIF; P=0.10), primary assisted patency (81.7% Group SIN vs. 76.4% Group BIF; P=0.53), secondary patency (85.1% Group SIN vs. 80.9% Group BIF; P=0.79), and limb salvage (92.3% Group SIN vs. 87.2% Group BIF; P=0.64). CONCLUSIONS Bifurcated graft improved time to healing in CLTI patients undergoing infrapopliteal non-reversed vein bypass. Two-year overall patencies and limb salvage did not differ accordingly to vein graft configuration (single vs. bifurcated).

Abstract
IntroductionCurrent evidence indicates endovascular intervention is a safe and effective treatment for peripheral artery disease of the lower extremity. However, the clinical outcome of endovascular intervention for femoropopliteal lesions has been shown to be affected by the status of tibial runoff. It remains unclear whether endovascular intervention for tibial runoff is associated with additional benefits.Methods and analysisThis prospective, multicenter, real-world observational study is carried out from January 2021 to December 2022 in 8 designated centers across China with an estimated sample size of 1200 patients with severe femoropopliteal disease. The pre-procedural status of tibial runoff is evaluated with the modified SVS score and categorized as good (SVS <5), compromised (SVS 5–10) or poor (SVS >10). Whether the patient will be treated with endovascular intervention for tibial runoff is determined by the treating vascular surgeons. Patients are dichotomized into the intervention group and the non-intervention group, with each group further divided into the good, compromised and poor tibial run-off subgroup, yielding 6 subgroups in total. Patients within various subgroups are compared with regard to the primary patency rate of the femoropopliteal artery, changes in quality of life, changes of Rutherford category, improvement of the Wound, Ischemia, and Foot Infection Classification, and incidence of major adverse events over 24-months follow-up. The results of this study may provide important information to help vascular sspecialists to decide whether the tibial runoff should be endovascularly intervened and which patient population benefits most from tibial runoff intervention.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/NCT04675632?id=NCT04675632&draw=2&rank=1, NCT04675632.

Ann Vasc Surg 2022; 88:182-190. [PMID: 36007776 DOI: 10.1016/j.avsg.2022.08.004] [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: 06/13/2022] [Revised: 07/17/2022] [Accepted: 08/07/2022] [Indexed: 11/16/2022]
Abstract
OBJECTIVE This study evaluated the mid-term results of endovascular therapy (EVT) for Trans-Atlantic Inter-Society (TASC) II D femoropopliteal lesions in patients with critical limb ischaemia (CLI). METHODS Fifty-seven limbs of 54 patients with CLI due to TASC II D femoropopliteal lesions who underwent EVT at the First Hospital of Hebei Medical University were retrospectively analysed in single-centre, observational study. The patient characteristics, endovascular procedural details, freedom from target lesion revascularisation (TLR), patency rates, ulcer healing rate, and limb salvage rate were accessed. RESULTS The patients' mean age was 68.2 ± 8.2 years. All patients were treated by EVT. The final technical success rate was 98.2% (56/57). There were 23 cases of pain at rest, 18 cases of ulcer, and 15 cases of gangrene. The median length of the treated segment was 286 ± 42 mm (56/56) and the mean number of stents placed per patient was 2.0 ± 0.8 (49/56). The postoperative ankle-brachial index (ABI) was significantly higher than that of the preoperative ABI (P < 0.05). The perioperative complication rate was 10.7% (6/56). The re-stenosis or occlusion rate was 44.6% (25/56). The estimated rates of freedom from TLR at 1 year, 2 years, and 3 years were 86.8%, 67.0%, and 62.5%, respectively. Univariate analysis showed that predictors of freedom from TLR were the number of runoff vessels, length of the lesion, and complexity of the lesion, while predictors for re-stenosis or occlusion were the length and the complexity of the lesion. The ulcer healing rate was 93.8%. The limb salvage rates were 76.4%, 74.4%, and 70.9% at 1, 2, and 3 years after treatment, respectively. CONCLUSIONS The mid-term outcomes of EVT for TASC II D femoropopliteal lesions in patients with CLI indicated that this treatment approach is safe and effective, and is clinically applicable.

Abstract
Background We aimed to characterize the occurrence of major adverse cardiovascular and limb events (MACE and MALE) among patients with peripheral artery disease (PAD) undergoing peripheral vascular intervention (PVI), as well as associated factors in patients with chronic limb threatening ischemia (CLTI). Methods and Results Patients undergoing PVI in the American College of Cardiology's (ACC) National Cardiovascular Data Registry's PVI Registry who could be linked to Centers for Medicare and Medicaid Services data were included. The primary outcomes were MACE, MALE, and readmission within 1 month and 1 year following index CLTI-PVI or non-CLTI-PVI. Cox proportional hazards regression was used to identify factors associated with the development of the primary outcomes among patients undergoing CLTI-PVI. There were 1758 (49.7%) patients undergoing CLTI-PVI and 1779 (50.3%) undergoing non-CLTI-PVI. By 1 year, MACE occurred in 29.5% of patients with CLTI (n=519), and MALE occurred in 34.0% of patients with CLTI (n=598). By 1 year, MACE occurred in 8.2% of patients with non-CLTI (n=146), and MALE occurred in 26.1% of patients with non-CLTI (n=465). Predictors of MACE at 1 year in CLTI-PVI included end-stage renal disease on hemodialysis, congestive heart failure, prior CABG, and severe lung disease. Predictors of MALE at 1 year in CLTI-PVI included treatment of a prior bypass graft, profunda femoral artery treatment, end-stage renal disease on hemodialysis, and treatment of a previously treated lesion. Conclusions Patients ≥65 years old undergoing PVI experience high rates of MACE and MALE. A range of modifiable and non-modifiable patient factors, procedural characteristics, and medications are associated with the occurrence of MACE and MALE following CLTI-PVI.

Abstract
PURPOSE To determine the correlation between upstream atherosclerosis in the femoropopliteal arteries, assessed using angioscopy, and impaired infrapopliteal runoff. MATERIALS AND METHODS Thirty-one patients with peripheral arterial disease who underwent endovascular therapy and angioscopy were prospectively included. Yellow plaque color scores were semiquantitatively determined as 0, 1, 2, or 3. Irregular plaques with rough surfaces, similar to gastric ulcers, were defined as ulcerated plaques (UPs). Angioscopic data were correlated with angiographic runoff scores (ARS). RESULTS UPs were detected in 74.2% of enrolled diseased legs using angioscopy. Mural thrombi were more commonly observed in the femoropopliteal artery in patients with UPs than in those without UPs (91.3% vs 37.5%, respectively; P = .006) and were frequently found on the UPs (21/23 patients with UPs). Univariate and multivariate linear regression analyses revealed that the presence of UPs was positively and independently associated with a poor ARS and that oral anticoagulant use was independently associated with a preferable ARS (standardized β = 0.462, P = .004 and standardized β = -0.411, P = .009, respectively, in the multivariate analysis). CONCLUSIONS UPs, associated with mural thrombi and diagnosed by angioscopic examination, were demonstrated to be one of the factors associated with poor infrapopliteal runoff.

The association of healthcare disparities and patient-specific factors on clinical outcomes in peripheral artery disease. Am Heart J 2021; 239:135-146. [PMID: 34052213 DOI: 10.1016/j.ahj.2021.05.014] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Accepted: 05/20/2021] [Indexed: 01/29/2023]
Abstract
BACKGROUND PAD increases the risk of cardiovascular mortality and limb loss, and disparities in treatment and outcomes have been described. However, the association of patient-specific characteristics with variation in outcomes is less well known. METHODS Patients with PAD from Duke University Health System (DUHS) between January 1, 2015 and March 31, 2016 were identified. PAD status was confirmed through ground truth adjudication and predictive modeling using diagnosis codes, procedure codes, and other administrative data. Symptom severity, lower extremity imaging, and ankle-brachial index (ABI) were manually abstracted from the electronic health record (EHR). Data was linked to Centers for Medicare and Medicaid Services data to provide longitudinal follow up. Primary outcome was major adverse vascular events (MAVE), a composite of all-cause mortality, myocardial infarction (MI), stroke, lower extremity revascularization and amputation. RESULTS Of 1,768 patients with PAD, 31.6% were asymptomatic, 41.2% had intermittent claudication (IC), and 27.3% had chronic limb-threatening ischemia (CLTI). At 1 year, patients with CLTI had higher rates of MAVE compared with asymptomatic or IC patients. CLTI and Medicaid dual eligibility were independent predictors of mortality. CLTI and Black race were associated with amputation. CONCLUSIONS Rates of MAVE were highest in patients with CLTI, but patients with IC or asymptomatic disease also had high rates of adverse events. Black and Medicaid dual-eligible patients were disproportionately present in the CLTI subgroup and were at higher risk of amputation and mortality, respectively. Future studies must focus on early identification of high-risk patient groups to improve outcomes in patients with PAD.

Abstract
PURPOSE OF REVIEW Certain comorbidities and lesion characteristics are associated with increased risk for procedural complications, limb events, and cardiovascular events following peripheral vascular intervention (PVI) in patients with peripheral arterial disease (PAD). The purpose of this review is to provide an overview of high-risk modifiable and unmodifiable patient characteristics and its relative impact on clinical outcomes such as amputation risk and mortality. Furthermore, general approaches to potentially mitigating these risks through pre-intervention planning and use of modern devices and techniques are discussed. RECENT FINDINGS Diabetes, tobacco use, and older age remain strong risk factors for the development of peripheral arterial disease. Recent data highlight the significant risk of polyvascular disease on major limb and cardiac events in advanced PAD, and ongoing studies are assessing this risk specifically after PVI. Challenging lesion characteristics such as calcified disease and chronic total occlusions can be successfully treated with PVI by utilizing novel devices (e.g., intravascular lithotripsy, re-entry devices) and techniques (e.g., subintimal arterial "flossing" with antegrade-retrograde intervention). Understanding high-risk patient comorbidities and lesion characteristics will improve our ability to counsel and manage patients with advanced PAD. Continued device innovation and novel techniques will aid in procedural planning for successful interventions to improve clinical outcomes.

Significance of Distal Runoff Score as a Key Influencer on Clinical Outcomes after Endovascular Interventions for Superficial Femoral Artery Disease. Ann Vasc Surg 2020; 73:234-243. [PMID: 33359690 DOI: 10.1016/j.avsg.2020.11.024] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 11/11/2020] [Accepted: 11/12/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND Endovascular therapy (EVT) is being adopted by many surgeons as a suitable first choice in the treatment of most femoropopliteal disease when clinically indicated. However, there are multiple factors affecting the outcome of EVT including the anatomy of lesions and distal runoff status. The evidence of runoff effect on the outcome of superficial femoral artery (SFA) interventions is still scarce and not well studied in the current literature. The aim of this study was to investigate the effect of runoff score on the outcomes of SFA endovascular interventions. METHODS Retrospective analysis was carried out on prospectively collected data on patients who underwent SFA endovascular intervention for critical limb ischemia (CLI) in a single tertiary center. Patients with Rutherford categories 4, 5, and 6 who did not have any previous vascular interventions were included in the study. The modified SVS runoff score was used after calculating scores from popliteal and all tibial vessels. Runoff was stratified into good (score <5), compromised (score 5-10), and poor (score >10). Amputation-free survival, patency rates, and overall survival were compared between all groups at 5 years. RESULTS Between 2011 and 2018, 254 procedures were performed in 220 patients. Technical success was >92%; 66 patients required SFA stents, and 55 had concomitant tibial angioplasty. There was no significant difference between good, compromised, or poor runoff groups regarding complication rates, with 3.5% overall perioperative mortality (5 cases in the compromised group and 4 in the poor runoff group). A runoff score of <5 was associated with significantly marked clinical improvement (P < 0.001). Patency rates were significantly worse in the compromised and poor runoff groups, with 5-year cumulative primary patency rates of 80%, 50%, and 22% in the good, compromised, and poor runoff groups, respectively (P < 0.001). Amputation-free survival worsened as the runoff got poorer with 98%, 91%, and 78% in the good, compromised, and poor runoff groups, respectively, at 5 years (P < 0.001). SFA stenting and concomitant tibial angioplasty led to slight improvement in patency rates in the poor runoff group. CONCLUSIONS Poor runoff with a score of >10 was associated with significantly reduced amputation-free survival and patency rates at 5 years in patients undergoing SFA endovascular intervention for CLI. Patients with a runoff score of <5 showed marked clinical improvement postoperatively when compared with patients with a runoff score of ≥5.

Abstract
We retrospectively analyzed all endovascular procedures of infrapopliteal arterial lesions (n = 383) performed in 270 patients at our institution between December 2008 and January 2018. The overall technical success rate was 97% and yielded 98% for stenoses (n = 214) and 95% for occlusions (n = 169). Trans-Atlantic Inter-Society Consensus (TASC II) classification had no impact on success rates (TASC A + B vs C + D; 96.5% vs 96.9%, p = 0.837). Freedom from clinically driven target lesion revascularization (TLR) after 6 and 12 months was 88.3% and 77.2%. TLR was comparable for TASC A to C lesions and no difference was observed comparing groups of moderately complex TASC A/B lesions and more complex TASC C/D lesions (TASC A + B vs C + D; 78.5% vs 74.2%, p = 0.457). Freedom from TLR was significantly lower in very complex TASC D lesions (TASC A + B + C vs D; 79.7% vs 42.5%, p < 0.001). Multivariate analysis identified TASC D lesions (hazard ratio D/A: 1.5; overall p = 0.002), Fontaine class III and IV (hazard ratio III or IV/IIa or IIb: 2.4; p = 0.041), and occlusive lesions (hazard ratio occlusion/stenosis: 2.4; p = 0.026) as predictors for TLR. In conclusion, endovascular therapy for infrapopliteal artery disease was safe and accompanied with a promising long-term outcome.

Prevalence and Outcomes of Endovascular Infrapopliteal Interventions for Intermittent Claudication. Ann Vasc Surg 2020; 70:79-86. [PMID: 32866579 DOI: 10.1016/j.avsg.2020.08.097] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2020] [Revised: 08/10/2020] [Accepted: 08/12/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Although endovascular peripheral vascular interventions (PVI) are typically limited to vessels above the knee in intermittent claudication (IC), some patients have concomitant or isolated infrapopliteal disease with IC. The benefits and risks of undergoing tibial intervention remain unclear in IC patients. The purpose of this study is to evaluate the prevalence and outcomes of infrapopliteal PVI for IC. METHODS The Vascular Quality Initiative was queried for PVI procedures performed for IC between 2003 and 2018. Patients were divided into 3 groups: isolated femoropopliteal (FP), isolated infrapopliteal (IP), and combined above and below knee interventions (COM). Multivariable logistic regression models identified predictors of minor and major amputation, as well as freedom from reintervention. Kaplan-Meier plots estimate amputation-free survival. RESULTS We identified 34,944 PVI procedures for IC. There were 31,110 (89.0%) FP interventions, 1,045 (3.0%) IP interventions, and 2,789 (8.0%) COM interventions. Kaplan-Meier plots of amputation-free survival revealed that patients with any IP intervention had significantly higher rates of both minor and major amputation (log rank <0.001). Freedom from reintervention at 1-year was 89.2% for the FP group, 91.3% for the IP group, and 85.3% for the COM group (P < 0.0001). In multivariable analysis, factors associated with an increased risk of major amputation included isolated IP intervention (OR 6.47, 95% CI, 6.45-6.49; P < 0.0001), COM interventions (OR 2.32, 95% CI, 2.31-2.33; P < 0.0001), dialysis dependence (OR 3.34, 95% CI, 3.33-3.35; P < 0.0001), CHF (OR 1.86, 95% CI, 1.85-1.86; P = 0.021) and, nonwhite race (OR 1.64, 95% CI, 1.63-1.64; P = 0.013). CONCLUSIONS PVI in the infrapopliteal vessels for IC is associated with higher amputation rates. This observation may suggest the need for more careful patient selection when performing PVI in patients with IC where disease extends into the infrapopliteal level.

Popliteal Artery Angioplasty for Chronic Total Occlusions with versus without the Distal Landing Zone. Ann Vasc Surg 2020; 68:417-425. [PMID: 32428645 DOI: 10.1016/j.avsg.2020.04.054] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Revised: 04/21/2020] [Accepted: 04/22/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND The purpose of this study was to evaluate the outcome of percutaneous transluminal angioplasty in patients with critical limb ischemia due to popliteal artery (PA) chronic total occlusions depending on the presence of a patent portion of the PA distal to the occlusive lesion-the distal landing zone (DLZ). MATERIALS AND METHODS We retrospectively analyzed 80 patients with critical limb ischemia (all Rutherford class 5-6), who underwent percutaneous transluminal angioplasty with or without stenting for PA chronic total occlusions with no inflow disease. Baseline demographic and clinical variables, periprocedural outcome, 12-month overall survival, limb salvage, primary patency, freedom from target lesion revascularization (TLR), amputation-free survival, and freedom from major adverse limb events in DLZ versus no-DLZ lesions were assessed. RESULTS Of all patients (43 men; mean age 70.2 y), 40 (50%) had DLZ in the PA, whereas another 40 (50%) did not (no-DLZ). Diabetes was significantly more common among DLZ patients and was found to be a risk factor for DLZ compared with no-DLZ lesions (HR 2.58; 95% CI 1.03-6.46; P = 0.04). Other demographic and clinical variables were similar between the groups. The stenting rate was 45.0% versus 42.5% in DLZ versus no-DLZ (P = 1.0). At 12 months, there was no significant difference in primary patency (64.7% vs. 51.6%; P = 0.156), overall survival (73.4% vs. 84.0%; P = 0.283), amputation-free survival (60.0% vs. 68.8%; P = 0.432), and limb salvage rate (93.6% vs. 82.2%; P = 0.126) between DLZ and no-DLZ groups, respectively. However, freedom from TLR (92.1% vs. 67.7%; P = 0.03) and major adverse limb events (80.1% vs. 41.8%; P = 0.003) was significantly higher in DLZ compared with no-DLZ lesions (92.1% vs. 67.7%; P = 0.03). CONCLUSIONS Diabetes was found to be a significant risk factor for DLZ compared to no-DLZ lesions. Technical success and stenting rates were similar in DLZ versus no-DLZ patients. At 12 months, there was no significant difference in limb salvage, primary patency, and overall survival between the study groups. The DLZ lesions were associated with a significantly higher freedom from TLR than no-DLZ lesions.

Abstract
Atherosclerotic diseases may include femoropopliteal artery stenosis or occlusion. Percutaneous transluminal angioplasty (PTA) is an effective and minimally invasive treatment strategy for atherosclerotic femoropopliteal artery stenosis/occlusion disease. Balloon angioplasty is a widely used technique in the management of occlusive disease in almost all arterial segments.We enrolled 111 diabetics with long femoropopliteal lesions, among which 54 received PTA with paclitaxel-coated balloon (the Paclitaxel group), and 57 with standard balloon catheters (the Control group).The primary outcome was set as angiographic late lumen loss (LLL) within 6 months; the secondary angiographic outcome was binary restenosis. Clinical outcomes included Rutherford clarification, ankle-brachial index (ABI) and rate of clinically driven target lesion revascularization (TLR). Two groups had similar basal clinical features, angiographic and procedural characteristics. Compared to controls, the Paclitaxel group had a significantly lower 6-month LLL rate, 12-month binary restenosis rate, 12-month TLR, lower Rutherford grades at 3 and 6 months, and higher ABI at 3 months. For all factors which might influence outcomes, fasting blood glucose was negatively correlated with ABI; the blood urea nitrogen (BUN) was positively related with the Rutherford clarification grades. In addition, the coronary heart disease (CHD) and smoking histories were positively correlated with residual stenosis after treatment.Collectively, the paclitaxel-coated balloon angioplasty can yield more favorable angiographic and clinical outcomes than standard uncoated balloon angioplasty, even in the more challenging lesions (the long and occlusive femoropopliteal lesions) in diabetics, when it had a similar safety profile to the traditional balloon. Blood glucose, BUN, CHD, and smoking imply poor curative effects.
