Abstract
Endovascular management of peripheral arterial disease is continually evolving. Most changes focus on addressing the challenges that hinder optimal patient outcomes; one of the most significant is how to best treat calcified lesions. Hardened plaque results in a variety of technical issues including impaired device delivery, decreased luminal revascularization, poor stent expansion, heightened risk of in-stent stenosis or thrombosis, and increased procedural time and cost. For this reason, plaque modification devices have been developed to mitigate this issue. This paper will describe these strategies and provide the reader with an overview of devices that can be used to treat chronically hardened lesions.

Abstract
Balloon angioplasty with/without utilizing drug eluting technology or stenting constitutes the treatment of choice for a significant percentage of patients with peripheral artery disease requiring an intervention. However, in cases of diffuse disease and plaque complexity, angioplasty may lead to dissection, recoil, and/or early restenosis, making vessel preparation a key component for successful and durable endovascular revascularization outcome. This review of literature aims to present contemporary data for several commercially available specialty balloons that have been designed to minimize the arterial wall stress of conventional balloon angioplasty and facilitate technical success, as well as long-term patency.

Abstract
BACKGROUND Endovascular interventions in infrapopliteal occlusive artery disease are becoming more complex, and this frequently tests the standard method of treatment, plain old balloon angioplasty (POBA). The potential that serration angioplasty could produce a more acceptable tibial artery lumen was assessed in this study. AIM The aim of this single-center subgroup analysis was to compare acute angiographic results after endovascular treatment using the Serranator serration balloon catheter in patients participating in the PRELUDE-BTK trial with POBA of the infrapopliteal arteries. A secondary objective was to assess post-treatment hemodynamic improvements. METHODS Our center enrolled 15 subjects and treated 17 lesions within the multicenter prospective core laboratory-adjudicated PRELUDE-BTK study. A 25 lesions analyzed separately were treated with POBA and then compared with the Serranator subset. In both cohorts, lesions were treated with either plain angioplasty or Serranator as a stand-alone therapy; subsequent methods, such as drug elution technologies, were not used. Acute angiographic results were analyzed by the SynvaCor angiographic core laboratory. To assess volumetric flow rates, data were analyzed with a fluid flow simulation software and compared against Poiseuille's Law. RESULTS Final residual stenosis was 17.2%±8.2% in the Serranator group versus 33.7%±15.7% in the POBA group. The mean lumen diameter (MLD) gain for the Serranator group and the POBA group was 1.64±0.41 mm and 1.33±0.63 mm, respectively. The average atmospheric balloon inflation pressure was 5 ATM in the Serranator group versus 9 ATM in the POBA group. Neither group required a bailout stent; however, it was notable that there were significantly more chronic total occlusions (CTOs) treated in the Serranator group at 41.2% versus 12% in the POBA group. Regarding the effectiveness in improving hemodynamic blood flow for non-CTO lesions, the calculated average ratio of post-treatment to pre-treatment flow rates in the Serranator group was 238% than that for the POBA group. For CTO cases where pre-treatment flow rate was zero, final residual stenosis was used as the parameter for comparison. The Serranator group showed a 62% improvement in final residual stenosis over POBA. CONCLUSION Endovascular treatment of the infrapopliteal arteries by use of the Serranator serration balloon provides a novel and promising method of action compared with standard balloon angioplasty and, thus, may have a leading role in complex below-the-knee arterial lesions. CLINICAL IMPACT The Serranator device might help to adequately address issues with conventional routine techniques for the treatment of complex lesions in infrapopliteal arteries in patients with advanced stages of PAD and critical limb ischemia. Integrating modern technologies such as the Serranator balloon catheter into clinical routine is mandatory in order to gain a more favorable outcome in these severely diseased patients and, particularly, to reduce mortality and morbidity.

Abstract
BACKGROUND Little data guides revascularization of infrapopliteal peripheral arterial disease (PAD) in patients with claudication. We assessed outcomes after infrapopliteal-only intervention for claudication in the LIBERTY 360 observational study. METHODS In this post hoc analysis, LIBERTY 360 patients (N = 128) with claudication and isolated infrapopliteal disease undergoing endovascular revascularization were divided by territory into anterior-vessel, posterior-vessel, or all-vessel groups. Patients were followed for periprocedural, in-hospital, and long-term outcomes. Logistic regression for odds ratios, Cox proportional hazard models, ANOVA, and Kaplan-Meier estimates were utilized to compare outcomes. RESULTS Patients underwent anterior (N = 37), posterior (N = 76), or all-vessel (N = 15) infrapopliteal revascularization. Initial procedural success was 86%, 86%, and 69% for anterior, posterior, and all-vessel groups, respectively. Each group had improvements in Rutherford classification (RC) from baseline to 2 years (mean RC change: -1.3, -1.5, and -1.5, respectively). Compared with all-vessel intervention, both anterior and posterior groups had lower rate of major adverse events (MAE) and target vessel revascularization (TVR) at 3 years (MAE: 12% and 15% in anterior and posterior groups, respectively compared with 51% in the all-vessel group; hazard ratios and 95% CIs 0.22 [0.06-0.74], p = .015; 0.24 [0.09-0.64], p = .004). Other outcomes were similar among the three groups. The anterior group showed more improvement in pain subdomain and total VascuQoL scores compared with posterior and all-vessel groups at 2 years (p = .016, p = .020 and p = .068, p = .009, respectively). CONCLUSIONS Both anterior or posterior revascularization have favorable outcomes and may be beneficial for improvement of symptoms in claudicants with isolated infrapopliteal PAD.

Abstract
Critical limb ischemia (CLI) is defined as chronic rest pain and/or the presence of tissue loss (ulcers or gangrene) in the lower extremities secondary to ischemia. CLI is a limb and potentially life-threatening disease associated with a poor prognosis with only 50% of patients being able to preserve both limbs within 12 months of diagnosis. CLI related to diabetes is often more extensive with multi-level long segmental arterial disease resulting in a 5–30-fold increased rate of amputation. As the incidence and prevalence of diabetes mellitus increases within our aging society, the rate of infrapopliteal artery occlusive disease (IPOD) and the need for intervention rises with it. The aim of this manuscript is to provide the reader with an overview of the various devices available for vessel preparation (VP) and treatment of IPOD in order to optimize patency rates, symptom resolution, healing of wounds, and minimize complications.

Abstract
Endovascular revascularization has been increasingly utilized to treat patients with chronic limb-threatening ischemia (CLTI), particularly atherosclerotic disease in the infrapopliteal arteries. Lesions of the infrapopliteal arteries are the result of 2 different etiologies: medial calcification and intimal atheromatous plaque. Although several devices are available for endovascular treatment of infrapopliteal lesions, balloon angioplasty still comprises the mainstay of therapy due to a lack of purpose-built devices. The mechanism of balloon angioplasty consists of adventitial stretching, medial necrosis, and dissection or plaque fracture. In many cases, the diffuse nature of infrapopliteal disease and plaque complexity may lead to dissection, recoil, and early restenosis. Optimal balloon angioplasty requires careful attention to assessment of vessel calcification, appropriate vessel sizing, and the use of long balloons with prolonged inflation times, as outlined in a treatment algorithm based on this systematic review. Further development of specific devices for this arterial segment are warranted, including devices for preventing recoil (eg, dedicated atherectomy devices), treating dissections (eg, tacks, stents), and preventing neointimal hyperplasia (eg, novel drug delivery techniques and drug-eluting stents). Further understanding of infrapopliteal disease, along with the development of new technologies, will help optimize the durability of endovascular interventions and ultimately improve the limb-related outcomes of patients with CLTI.

Abstract
BACKGROUND To evaluate the safety, feasibility and effectiveness of high-pressure, noncompliant balloon angioplasty in the management of long infrapopliteal calcified lesions. METHODS Consecutive patients, presenting with chronic limb-threatening ischemia (CLTI) and long (>100 mm) calcified infrapopliteal lesions who were treated with a high pressure, noncompliant balloon (JADE, OrbusNeich, Hong Kong) between January 2016 and July 2016 were retrospectively analyzed. Angioplasty was performed by inflating the balloon to a pressure of 22 to 24 atm for 90 seconds. Primary outcome was technical success. Secondary outcomes were procedure-related complications, limb salvage, amputation-free survival (AFS), wound healing, overall survival, freedom from clinically driven target lesion reintervention (CD-TLR), and resolution of CLTI at 2 and 3 years. RESULTS Overall, 23 lesions in 21 limbs of 20 patients were treated. All patients had tissue loss (Rutherford 5 or 6). The mean lesion length was 374.8 mm. Of all lesions, 56.5% were occlusions, 91.3% were classified as TransAtlantic Inter-Society Consensus (TASC) C and D lesions, and 78.3% had severe calcification classification. Of all lesions, 52.2% extended into the below-the-ankle arteries. Technical success was achieved in 22 lesions (95.7%). There were no procedure-related complications. No bailout stenting was required. At 2 and 3 years, limb salvage was 84.7% and 78.7%, AFS was 71.4% and 56.1%, wound healing was 81.0% and 85.7%, overall survival was 75.0% and 64.3% and freedom from CD-TLR was 77.6% and 63.5%, respectively. Resolution of CLTI without TLR was 81.0% at 2 and 3 years. CONCLUSIONS This study is the first to analyze safety and feasibility of a high-pressure, noncompliant balloon for long, calcified infrapopliteal and inframalleolar lesions.

Abstract
The incidence of in-stent restenosis (ISR) has declined dramatically, but once it develops, no current treatment option, such as drug-eluting stents, drug-coated balloons, or cutting balloons (CBs), prevents re-narrowing of the stented atherosclerotic artery. In this preclinical study, we aimed to improve the efficacy of ISR treatment by coating CBs with paclitaxel (paclitaxel-eluting cutting balloon; PECB) and to characterize the histological features of neo-ISRs that arise after ISR treatment. ISR was induced by bare metal stent (BMS) implantation in coronary arteries in pigs. After one month of follow-up, the BMS-induced ISR was treated with either CB or PECB. After another month, we performed quantitative coronary angiography, explanted the treated arteries and assessed histopathological and histomorphometric parameters. In addition, we compared the histological features of neo-ISRs with pre-treatment ISRs. Injury, inflammation, fibrin deposition, and endothelialization scores were similar between the CB and PECB groups at one month after ISR treatment. Neointimal area (0.87±0.61 vs. 1.95±1.14 mm², p=0.02), mean neointimal thickness (0.40±0.39 vs. 0.99±0.56 mm, p=0.01), and percent area stenosis (27.3±20.4 vs. 48.3±22.9%, p=0.04) were decreased in PECB-treated coronary arteries compared to CB-treated arteries, respectively. Density of cells (predominantly smooth muscle cells; SMCs) was increased in neo-ISRs (3.51±3.05×10³ vs. 6.35±2.57×10³ cells/mm², p<0.01), but significantly more CD68⁺ and CD20⁺ cells were found in the pre-treatment ISRs. In conclusion, PECB treatment of ISRs led to better results in terms of smaller neointimal area and %area stenosis of the neo-ISR. SMC density was increased in neo-ISRs in contrast with higher percentage of CD68⁺ and CD20⁺ cells in pre-treatment ISRs.

Abstract
INTRODUCTION Percutaneous transluminal angioplasty (PTA) currently remains the endovascular treatment of choice in a large percentage of patients suffering from peripheral artery disease (PAD). However, the mechanism of angioplasty itself can cause some extent of arterial dissection leading to early vessel restenosis/reocclusion. Current endovascular imaging studies have reported a higher rate of arterial dissection than previously reported in literature and advocated the correlation of dissection with poor patency. Thus, there is the need of developing devices to minimize dissection and bailout stenting. AREAS COVERED The present review focuses on newly-developed balloon angioplasty technologies designed to minimize arterial wall distress and consequently the rate of dissections. Available literature regarding three new specialty balloons is being reviewed, highlighting their value and limitations. Authors' future perspective about the benefits of utilizing specialty balloons towards a metal free and dissection free future is also provided. EXPERT OPINION By understanding the mechanism of angioplasty and thus developing devices which cause minimal or no arterial wall distress, the rate of dissections and bailout stenting can be minimized and long-term clinical outcomes of endovascular therapy can be optimized.

Abstract
BACKGROUND Chronic total occlusion (CTO) of femoropopliteal artery (FP) continues to be a lesion subset where maintaining long-term patency after endovascular treatment is challenging. We evaluated the efficacy of cutting balloon angioplasty (CBA) for de novo FP-CTOs in patients with symptomatic lower limb ischemia. METHODS Seventy-three limbs of 67 symptomatic patients with de novo FP-CTOs successfully recanalized using CBA alone were enrolled in this study. Primary patency was defined as the absence of recurrent symptoms and no deterioration of the ankle-brachial index (ABI) >0.10 from the immediate postinterventional value. RESULTS The mean age was 73.5 ± 7.3 years, and 59.7% of patients had diabetes mellitus. Most lesions were classified as Trans-Atlantic Inter-Society Consensus II type C (n = 18; 24.7%) or type D (n = 44; 60.3%), with mean lesion and occluded lengths of 24.8 ± 11.4 and 17.8 ± 11.2 cm, respectively. No procedure-related adverse events occurred, except one distal embolization. The ABI significantly increased after intervention from 0.52 ± 0.12 to 0.80 ± 0.15 (P < 0.0001), with marked improvement in clinical symptoms (Rutherford stage: 2.7 ± 1.0 to 1.1 ± 1.2, P < 0.0001). The mean follow-up period was 31.2 ± 18.0 months, and the primary patency rates at 12 and 24 months were 75.3% and 60.6%, respectively. The independent predictive factors of failed patency were baseline hemoglobin A1c (P = 0.031, hazard radio [HR] 1.51 per 1%), occluded length ≥15 cm (P = 0.036, HR 2.90), and severe dissection (P = 0.033, HR 2.85). Vessel calcification and diameter did not affect primary patency. CONCLUSIONS CBA is a feasible option for endovascular treatment of FP-CTOs. Diabetic status, occlusion length, and severe dissection after CBA are independent negative predictors of long-term patency.

Abstract
Modern therapy, including endoluminal procedures and improved medical management, still yield less than desired results for tibial vessel occlusive disease. Despite the recent focus on these newer interventions, few modern series have evaluated the efficacy of popliteal-to-distal bypass procedures. The authors aimed to determine the efficacy of popliteal-distal bypass and to identify adverse prognostic factors for ultimate limb salvage. Eighty-seven patients (54 men; average age: 63 years) underwent 92 popliteal-distal bypasses. Duplex ultrasound was utilized to assess patency of all grafts. Data were analyzed by life-table analysis to determine patency rates at postoperative intervals. Median patient follow-up was 2.4 years. Major indications for bypass included chronic limb ischemia (86%) and disabling claudication (8%); 62% of the limbs were considered threatened, and 74% of the proximal anastomoses were above-knee. All procedures were technically successful. There were no perioperative (<30 days) deaths, and 86% of patients were alive at 5 years. Cumulative patency rates were 74% at 6 months, 70% at 2 years, and 63% at 5 years. Limb salvage rates closely paralleled patency rates. At 5 years, 62% of the affected limbs were intact; 72% of the limbs lost were associated with early (<180 days) bypass failures. Predictors of limb loss included early graft failure (84 days vs 1,288 days, p <0.0001), younger age (57 years vs 64 years, p = 0.039), history of previous ipsilateral vascular procedures (50% vs 21%, p = 0.03), heavy (>1 ppd) tobacco use (p = 0.001), and a thrombosed femoral-popliteal bypass at presentation (p = 0.002). When successful, popliteal-distal bypass is associated with excellent long-term patency and limb salvage rates. Early failures are often associated with limb loss. Heavy tobacco use, younger age, early graft failures, repeat revascularization, and presentation with a thrombosed femoral-popliteal graft are associated with limb loss.

Abstract
Considerable advances have been made over the last decade in percutaneous technology for the treatment of atherosclerotic diseases in the femoro-popliteal arteries. While treatment strategies are well defined in the iliac segment, where angioplasty and stenting perform well in appropriately selected lesions, the search for a durable transcatheter therapy for femoro-popliteal lesions continues. Whereas balloon angioplasty (PTA) is the accepted therapy for short lesions, long diffuse lesions are still recommended for surgical treatment. However, attractive new technologies ranging from transcatheter plaque excision to laser ablation, rotational atherectomy, cryoplasty, brachytherapy, and placement of drug-eluting stents to simple angioplasty with drug-coated balloons may have the potential to replace femoro-popliteal bypass surgery as a treatment of choice for complex lesions. This article reviews the status of percutaneous endovascular techniques for the treatment of femoro-popliteal artery occlusive disease.

Abstract
Endovascular therapy for disease of the superficial femoral artery (SFA) and the popliteal artery remains controversial. Percutaneous treatment of this arterial segment presents a particular technical challenge, as the extent of disease varies from short, focal, and stenotic to long, diffuse, and occluded lesions. Over the last 2 decades, multiple therapies have been evaluated, including simple balloon angioplasty, directional atherectomy, stenting (both balloon-expandable and self-expanding), and more recently, intra-arterial radiation, laser, and cryotherapy. Regardless of which modality is used, however, endovascular therapy as a revascularization strategy has the potential to improve symptoms and quality of life and, in selected patients, to avoid limb amputation. While percutaneous endovascular treatment has been historically associated with high procedural success and favorable short and intermediate-term patency rates, long-term clinical results have proven disappointing. Conventional balloon angioplasty is limited by elastic recoil, dissection, and restenosis. Balloon-expandable stents (particularly in the distal SFA) are associated with late stent deformation and mechanical compression, with resultant late clinical failure. Newer self-expanding stents have shown improved initial results but have been limited by late mechanical fatigue and associated restenosis. With the development of several newer endovascular techniques in recent years, the possibilities for treating this condition have increased dramatically. Currently, no long-term comparative data exist regarding the role of these alternative technologies. This article summarizes and compares important data about new endovascular options for intervention therapy in SFA and popliteal disease. In addition, based on this analysis, we propose a contemporary treatment strategy, integrating older and newer technologies into a real-world algorithm.

Abstract
BACKGROUND The aim of the proposed study was to conduct a feasibility study using a flat rectangular (3 mm × 10 mm) MRI compatible transducer operating at 5.3 MHz for destroying calcified material in an in vitro model. The proposed method can be used in the future for treating atherosclerosis plaques of the coronary, carotid or peripheral arteries. METHODS The system was tested initially on calcium rods. Another test was performed in a hydroxyapatite-polylactide model. RESULTS A parametric study was performed where the mass of calcified material removed was studied as a function of intensity, pulse repetition frequency (PRF), duty factor (DF) and presence of bubbles. CONCLUSIONS The amount of calcified material removed is directly related to the intensity, PRF and DF. It was found that the presence of bubbles accelerates the removal of calcified material. In order to ensure that pure mechanical mode ultrasound was used, the protocols were designed so that the temperature does not exceed 1 °C.

Abstract
PURPOSE To evaluate the safety, feasibility, and effectiveness of cutting balloon angioplasty in the management of infrapopliteal bifurcation disease. METHODS Between November 2010 and March 2013, 23 patients (mean age 69.6±9.01 years, range 56-89; 16 men) suffering from critical limb ischemia were treated using cutting balloon angioplasty (single cutting balloon, T-shaped double cutting balloon, or double kissing cutting balloon technique) for 47 infrapopliteal artery bifurcation lesions (16 popliteal bifurcation and 9 tibioperoneal bifurcation) in 25 limbs. Follow-up consisted of clinical examination and duplex ultrasonography at 1 month and every 3 months thereafter. RESULTS All treatments were technically successful. No 30-day death or adverse events needing treatment were registered. No flow-limiting dissection was observed, so no stent implantation was necessary. The mean postprocedure minimum lumen diameter and acute gain were 0.28±0.04 and 0.20±0.06 cm, respectively, with a residual stenosis of 0.04±0.02 cm. Primary and secondary patency rates were estimated as 89.3% and 93.5% at 6 months and 77.7% and 88.8% at 12 months, respectively; 1-year primary and secondary patency rates of the treated bifurcation were 74.2% and 87.0%, respectively. The survival rate estimated by Kaplan-Meier analysis was 82.5% at 1 year. CONCLUSION Cutting balloon angioplasty seems to be a safe and effective tool in the routine treatment of short/ostial infrapopliteal bifurcation lesions, avoiding procedure-related complications, overcoming the limitations of conventional angioplasty, and improving the outcome of catheter-based therapy.

Abstract
PURPOSE To compare the acute outcomes of orbital atherectomy treatment in diabetic vs. non-diabetic patients with peripheral artery disease (PAD). METHODS The CONFIRM registry series contained 1842 diabetic patients (1111 men; mean age 70.6±10.2 years) with 2819 lesions and 1247 non-diabetic patients (732 men; mean age 72.9±10.7 years) with 1885 lesions. The composite rate of procedure-related complications, including dissection, perforation, slow flow, vessel closure, spasm, embolism, and thrombus formation, was analyzed for the diabetic and non-diabetic groups. RESULTS Diabetics were younger but had a higher prevalence of coronary artery disease (p<0.001), renal disease (p<0.001), hypertension (p<0.001), hyperlipidemia (p<0.001), and lower ankle-brachial index scores (p=0.007). Diabetics had more severe PAD (Rutherford category 4-6; p<0.001), longer lesions (p<0.001), more infrapopliteal lesions (58% vs. 46%, p<0.001), and more lesions with severe and moderate calcium (86% vs. 78%, p<0.001). Diabetic and non-diabetic patients had the same (21.8%) composite rate of procedure-related complications, as well as similar rates of dissection (11.4% vs. 10.8%, p=0.68), embolism (2.2% vs. 2.4%, p=0.67), and thrombus formation (1.3% vs. 1.1%, p=0.75). However, diabetics had lower rates of perforation (0.5% vs. 1.1%, p=0.03) and spasm (5.5% vs. 7.6%, p=0.005), but a higher rate of slow flow (5.0% vs. 3.5%, p=0.02) and a tendency toward increased vessel closure (1.7% vs. 0.9%, p=0.06). CONCLUSION Plaque modification with orbital atherectomy resulted in similar low procedure-related complication rates in both the diabetic and non-diabetic groups, despite diabetics having more unfavorable baseline clinical and lesion characteristics. This study suggests that orbital atherectomy is a safe and effective treatment modality in both the diabetic and the non-diabetic populations.

Abstract
The complex pathophysiology response to injury of the lower-extremity arteries has prompted the development of several unique balloon technologies to overcome initial technical failures and short-term intimal hyperplasia. Cryoplasty alters the cellular and mechanical properties of the vessel wall during angioplasty. Cutting balloons incise the wall, preventing elastic recoil and allowing expansion of the lumen at a lower pressure, thus limiting barotrauma. Drug-eluting balloons actively transfer inhibitory compounds to the wall during the initial therapy, while brachytherapy balloons allow for localized delivery of radiation to inhibit the proliferative response seen after angioplasty. These platforms provide unique means to enhance immediate and short-term results and also reduce stent usage in the lower extremity.

Abstract
INTRODUCTION Lower limb ischemia may cause nonhealing ulcers, infection, amputation and even mortality in diabetic patients. In this study, we review our data of ischemic lower limb revascularization procedures in diabetic patients and present the early, mid- and long-term results. MATERIAL AND METHODS From March 2004 to September 2008, 83 patients with lower limb ischemia in Fontaine class III and IV underwent distal arterial bypass procedures. Saphenous vein grafts were used for below-knee arterial bypasses in all patients. In 16 (19%) patients femoropopliteal bypasses were performed with PTFE grafts. Short-term and long-term surgical results were evaluated. RESULTS Ulcer recovery was determined in 36% of patients. Graft patency was 95% and 1 death (1%) occurred in short-term follow-up. In long-term follow-up the total effectiveness rate was 74%. Graft patency was 79% and 6 deaths (7%) occurred during the follow-up. CONCLUSIONS Lower limb ischemia is a serious event in patients with diabetes mellitus. The consequences may include increased mortality and morbidity in this particular patient population. However, distal arterial revascularizations are considerably effective procedures to avoid amputation, to eliminate symptoms, to promote ulcer recovery and to help the patient participate in social life with acceptable short, mid- and long-term follow-up results.

Abstract
Critical limb ischemia (CLI) represents the most severe clinical manifestation of peripheral arterial disease, defined as the presence of chronic ischemic rest pain, ulcers, or gangrene attributable to objectively proven arterial occlusive disease. The dominant pathology underlying CLI is atherosclerosis, distributed at multiple levels along the length of the lower extremity and with a propensity for involvement of the tibial vessels in the leg and the small vessels of the foot. To achieve limb salvage in patients with CLI, revascularization of the affected limb is generally required. In contemporary practice, endovascular techniques are rapidly replacing surgical bypass as the first option for revascularization for CLI based on high technical success rates and low rates of procedure-related morbidity and mortality. This review will describe the clinical strategy of the authors who have adopted an endovascular-first approach to revascularization in treating patients with CLI and summarize the clinical outcomes of endovascular therapy in this population.

In case of ureteral stenosis, to allow a correct insertion of the stent, a predilatation of the ureter stenosis with a conventional balloon catheter can be necessary. In exceptional cases, it can be difficult to advance an 7-8 Fr JJ-catheter over a tight resistant ureter stenosis following unsuccessful high-pressure balloon dilatation. In the present report, we describe two cases of resistant ureter stenosis successfully dilated by a cutting-balloon following the failure of high-pressure balloon dilatation, allowing a correct and uncomplicated antegrade stent insertion.

Abstract
Critical limb ischemia (CLI) remains a poorly understood, rarely reported, and inconsistently treated major global healthcare epidemic. The incidence in the US is estimated at 1% of the population aged 50 years and older and at approximately double that rate in the over-70 age group. These frequencies are expected to increase significantly with the aging population and the expected increase in diabetes. Within 1 year of being diagnosed with CLI, 40% to 50% of the now 20 million US diabetics will experience an amputation, and 20% to 25% will die. The estimate for treating CLI in the US alone is $10 to $20 billion per year, but just a 25% reduction in amputations could save $2.9 to $3.0 billion annually. Infrainguinal bypass surgery (IBS) utilizing autogenous saphenous vein has been considered the "24-carat gold standard" treatment for CLI, but over the last decade, endovascular therapy has emerged to seriously challenge IBS, which has created considerable controversy. Despite an overall lack of "hard" level I data, many interventionists are questioning the role of IBS as a first-line CLI therapy or are at least now considering IBS a "tainted" gold standard ("14-carat"). This review will examine the available evidence, but there should be no doubt regarding the huge global clinical and economic impact of CLI and amputations.

Abstract
Critical limb ischemia (CLI) is the term used to designate the condition in which peripheral artery disease has resulted in resting leg or foot pain or in a breakdown of the skin of the leg or foot, causing ulcers or tissue loss. If not revascularized, CLI patients are at risk for limb loss and for potentially fatal complications from the progression of gangrene and the development of sepsis. The management of CLI requires a multidisciplinary team of experts in different areas of vascular disease, from atherosclerotic risk factor management to imaging, from intervention to wound care and physical therapy. In the past decade, the most significant change in the treatment of CLI has been the increasing tendency to shift from bypass surgery to less invasive endovascular procedures as first-choice revascularization techniques, with bypass surgery then reserved as backup if appropriate. The goals of intervention for CLI include the restoration of pulsatile, inline flow to the foot to assist wound healing, the relief of rest pain, the avoidance of major amputation, preservation of mobility, and improvement of patient function and quality of life. The evaluating physician should be fully aware of all revascularization options in order to select the most appropriate intervention or combination of interventions, while taking into consideration the goals of therapy, risk-benefit ratios, patient comorbidities, and life expectancy. We discuss the incidence, risk factors, and prognosis of CLI and the clinical presentation, diagnosis, available imaging modalities, and medical management (including pain and ulcer care, pharmaceutical options, and molecular therapies targeting angiogenesis). The endovascular approaches that we review include percutaneous transluminal angioplasty (with or without adjunctive stenting); subintimal angioplasty; primary femoropopliteal and infrapopliteal deployment of bare nitinol, covered, drug-eluting, or bioabsorbable stents; cryoplasty; excimer laser-assisted angioplasty; excisional atherectomy; and cutting balloon angioplasty.

Abstract
PURPOSE To report the 12-month follow-up data from the prospective 16-center Below-the-Knee (BTK) Chill Trial, which examined the use of primary cryoplasty for BTK occlusive disease in patients with critical limb ischemia (CLI). METHODS The trial included 108 patients (77 men; mean age 73 +/- 11 years, range 41-101) with CLI (Rutherford categories 4-6) involving 111 limbs with 115 target infrapopliteal lesions. Angiographic inclusion criteria were reference vessel diameter > or = 2.5 mm and < or = 5.0 mm and target lesion stenosis > or = 50%. The primary study endpoints were acute technical success (the ability to achieve < or = 50% residual stenosis and continuous inline flow to the foot) and absence of major amputation of the target limb at 6 months. Secondary endpoints were serious adverse events specifically related to use of primary cryoplasty and absence of major amputation of the target limb at 1, 3, and 12 months. RESULTS Acute technical success was achieved in 108 (97.3%) of treated limbs, with only 1 clinically significant dissection (> or = type C) and 2 residual stenoses >50%; stent placement was required following cryoplasty in only 3 (2.7%) procedures. At 6 months and 1 year, major amputation was avoided in 93.4% (85/91) and 85.2% (69/81) of patients, respectively. Through 1 year, 21% (17/81) of patients underwent target limb revascularization. Rates of major amputation and death at 1 year were 0% for limbs of patients with initial Rutherford category 4; 11.4% and 0%, respectively, for initial category 5; and 40.0% and 31.8% for initial category 6. One-year rates of major amputation and death were 20.4% and 8.8%, respectively, for diabetics, versus 4.0% and 10.7% for non-diabetics. At 1 year, major amputation occurred in 16.7% (2/12) of limbs that were expected to be amputated at the time of treatment. CONCLUSION Cryoplasty therapy is a safe and effective method of treating infrapopliteal disease, providing excellent results and a high rate of limb salvage in patients with CLI. Study outcomes through 1 year support the use of cryoplasty as a primary treatment option for patients with CLI secondary to BTK occlusive disease.

Abstract
The AngioSculpt Scoring Balloon Catheter (AngioScore, Inc., Fremont, CA) is composed of a semicompliant balloon encircled by three nitinol spiral struts providing targeted lesion scoring on balloon inflation. Between April 2005 and April 2006, procedural and follow-up data on 31 patients (mean age 76 years; 54.8% males) endovascularly treated for severe infrapopliteal disease were collected. The AngioSculpt catheter was used to treat 36 complex, tibioperoneal, atherosclerotic lesions. All patients had symptomatic critical limb ischemia (Rutherford 4–5) and single-vessel runoff to the ankle. Complication-free survival at 1 month was the safety end point, whereas primary patency and limb salvage were the efficacy end points evaluated at 1 year. The AngioSculpt balloon was successfully inflated in all 36 target lesions. Eleven patients (35.5%) required additional stenting for minor dissections or suboptimal stenosis reduction. The 1-month complication-free survival was 96.8%. One-year survival, primary patency, and limb salvage rates were 83.9 ± 6.6%, 61.0 ± 9.3%, and 86.3 ± 6.4%, respectively. The 1-year data show the AngioSculpt Scoring Balloon Catheter to be an effective and safe treatment for infrapopliteal, atherosclerotic lesions in patients with critical limb ischemia. However, more patients, a longer follow-up, and randomized studies comparing it with conventional balloon angioplasty and stenting in the infrapopliteal region are required.

Abstract
PURPOSE To compare midterm results of cutting balloon angioplasty (CBA) to conventional percutaneous transluminal angioplasty (PTA) for the treatment of short femoropopliteal arterial stenosis. METHODS Between February 2004 and June 2006, 84 consecutive patients (49 men; mean age 68.5 years, range 53-89) with a total of 142 focal (<3 cm), calcified femoropopliteal occlusive lesions underwent endovascular treatment via an antegrade approach: 40 patients (67 lesions) were treated with PTA and 44 patients (75 lesions) underwent CBA. Follow-up consisted of clinical examination and color duplex ultrasonography at intervals to 2 years. RESULTS All treatments were technically successfully, without any major complication. In 4 (6%) of 67 lesions treated with PTA, a self-expanding stent was implanted due to a flow-limiting dissection; no patient treated with CBA had recoil, dissection, or arterial tears requiring stent placement. In the PTA group, primary and secondary patency rates, respectively, were 91.0% and 95.5% at 6 months, 83.1% and 92.4% at 12 months, and 66.6% and 76.5% at 2 years. In the CBA patients, the primary and secondary patency rates, respectively, were 93.2% and 95.9% at 6 months, 90.4% (p<0.001 versus PTA at same interval) and 94.5% at 12 months, and 79.7% (p<0.001) and 85.6% (p<0.001) at 2 years. CONCLUSION CBA seems to be a valuable tool in the endovascular treatment of short femoropopliteal stenotic lesions, achieving better patency at midterm compared to conventional PTA.

Abstract
Abstract Chronic critical limb ischemia (CLI) occurs when arterial perfusion is reduced below a threshold level that results in rest pain and/or tissue breakdown in the lower extremities. Importantly, it is associated with high cardiovascular morbidity and mortality. Without prompt revascularization, CLI may result in loss of a limb (i.e. amputation) and/or life. The goal of endovascular therapy is the re-establishment of pulsatile, straight-line flow to the distal extremity. Percutaneous transluminal angioplasty (PTA) has been shown to be effective and safe in the setting of CLI, with limb salvage rates that compare favorably with surgical procedures. Stents are indicated for failed PTA, while adjunctive therapies such as lasers, thermal angioplasty and atherectomy devices lack data demonstrating improved efficacy compared with conventional lower extremity interventions. In addition to successful revascularization, the institution of lifestyle changes, atherosclerotic risk factor modification, and pharmacologic therapies are indicated to reduce cardiovascular morbidity and mortality.

Abstract
In this article, current evidence-based treatment recommendations for acute and chronic lower limb ischemia will be presented considering the varied possibilities of endovascular techniques and open surgical vascular strategies. Beside presentation of the different therapeutic possibilities, advantages of the combination of both techniques will be described. Despite the BASIL trial, there are no prospective randomised controlled trials comparing endovascular and open surgical interventions. Different therapeutic rules along the different vascular segments will be discussed for both acute and chronic peripheral arterial disease. Generally it can be stated that aortoiliac revascularization for chronic obstructions is increasingly being carried out by endovascular means or hybrid procedures using a minimally invasive femoral approach, whereas acute occlusions in this vascular segment are still treated with open surgical techniques (Fogarty balloon thrombectomy). In the infrainguinal region, endovascular therapeutic strategies are gaining favor. However, multilevel occlusions and long-segment obstructions in the femoral and popliteal segment are still treated by bypass procedures. Acute ischemia in the infrainguinal segment is increasingly treated with endovascular methods (local thrombolysis and percutaneous thrombectomy).

Abstract
The use of percutaneous closure devices post arterial punctures has been introduced to reduce time to haemostasis, reduce haemorrhage, improve patient comfort and reduce time to ambulation. Their increased use has been a result of larger access sites for more complicated procedures, periprocedural anticoagulation and concomitant use of anti-platelet therapy. Although complication rates are not increased with their use as compared with mechanical compression, complications may be more severe and are an important consideration in their use. We report two cases of iatrogenic stenoses secondary to suture-mediated closure device. The first managed with open surgical repair and the second with cutting balloon angioplasty.

Abstract
A retrospective study was carried out to evaluate the efficacy and safety of cutting-balloon angioplasty (CBA) for the predilatation of tight fibrocalcified carotid stenosis before carotid artery stenting (CAS). We also compared the intraprocedural results of CBA with those of conventional percutaneous transluminal angioplasty (PTA) in terms of postdilatation rate. The study population was composed of 32 patients who underwent CAS requiring predilatation before stent implantation. In detail, predilatation was performed by using a conventional balloon (PTA) in 14 patients (group A) and a cutting balloon (CBA) in 18 patients (group B). Intraprocedural and periprocedural mortality, major and minor procedural and neurologic complications, arterial damage, and embolic debris found in the distal filter were recorded. We statistically compared the rate of postdilatation obtained in the two groups. Technical success was obtained in 100% of the cases. No death, major neurologic or periprocedural complications, or arterial damage were recorded in either group. Minor neurologic reactions were recorded in 1 patient from group A (4%) and in 1 patient from group B (3%). Embolic debris was found in the distal filter in 2 patients from group A (8%) and in 3 patients from group B (10%). Postdilatation was necessary in 14 patients from group A (100%) and in 9 patients from group B (50%) (p < 0.05). Although limited to a small number of patients, compared with PTA, CBA seems to be a safe and effective procedure for the predilatation of tight fibrocalcified carotid stenoses before stent placement and may decrease the need for postdilatation in this patient population.

Abstract
PURPOSE To report the 1-year angiographic and clinical outcome from a prospective single-center study investigating the infrapopliteal application of sirolimus-eluting versus bare metal stents in patients with critical limb ischemia (CLI) who underwent below-the-knee endovascular revascularization. METHODS Stenting was performed as a bailout procedure for suboptimal angioplasty results (flow-limiting dissection, elastic recoil, or postangioplasty residual stenosis >30%). In the first 29 patients, infrapopliteal stenting was performed with bare metal stents (group B) and with sirolimus-eluting stents in the other 29 patients (group S). RESULTS Below-the-knee angioplasty and stenting involved 65 lesions in 40 infrapopliteal arteries of 29 limbs in group B and 66 lesions in 41 infrapopliteal arteries of 29 limbs in group S. Baseline comorbidities (hyperlipidemia and symptomatic cardiac and carotid disease) were more pronounced in group S (p<0.05). At 6 months, sirolimus-eluting stents demonstrated significantly higher primary patency (OR 5.625, 95% CI 1.711 to 18.493, p = 0.004) and decreased in-stent binary restenosis (OR 0.067, 95% CI 0.021 to 0.017, p<0.001) and in-segment binary restenosis (OR 0.229, 95% CI 0.099 to 0.533, p = 0.001). After 1 year, sirolimus-eluting stents were steadily associated with increased primary patency (OR 10.401, 95% CI 3.425 to 31.589, p<0.001) and significantly less in-stent (OR 0.156, 95% CI 0.060 to 0.407, p<0.001) and in-segment (OR 0.089, 95% CI 0.023 to 0.349, p = 0.001) binary restenosis. In addition, sirolimus-eluting stents were associated with significantly fewer cumulative target lesion reinterventions at 6 months (OR 0.057, 95% CI 0.008 to 0.426, p = 0.005) and 1 year (OR 0.238, 95% CI 0.067 to 0.841, p = 0.026). No significant differences between groups B and S were noted at 1 year with respect to mortality (10.3% versus 13.8%, respectively), minor amputation (17.2% versus 10.3%), or limb salvage (100% versus 96%). CONCLUSION The application of sirolimus-eluting stents reduces the restenosis rate in the infrapopliteal arteries and the rate of repeat endovascular procedures the first year after treatment.
