Abstract
PURPOSE Infrapopliteal lesions are generally complex to treat due to small vessel diameter, long lesion length, multilevel disease, and severe calcification. Therefore, different vessel preparation devices have been developed to contribute to better peri- and postprocedural outcomes. This systematic review aims to compare different vessel preparation techniques prior to plain old balloon angioplasty (POBA) or drug-coated balloon (DCB) angioplasty with POBA or DCB alone in infrapopliteal arterial disease. METHODS Medline, EMBASE, and Cochrane databases were searched for studies published between 2000 and 2022 assessing the value of adjunctive vessel preparation in infrapopliteal arterial disease. The primary outcomes were 12-month primary patency and limb salvage. RESULTS A total of 1685 patients with 1913 lesions were included in 11 POBA studies. Methodological quality was assessed as poor to moderate in these studies. Only 2 studies with 144 patients assessed vessel preparation in conjunction with DCB angioplasty. These randomized trials were assessed as high quality and found no significant benefit of adjunctive atherectomy to DCB angioplasty. The pooled Kaplan-Meier estimates of 12-month primary patency and limb salvage in the POBA studies were 67.8% and 80.9% for POBA, 62.1% and 86.4% for scoring balloons, 67.9% and 79.6% for mechanical atherectomy (MA), and 79.7% and 82.6% for laser atherectomy, respectively. Within the pooled data only scoring balloons and MA demonstrated significantly improved 12-month limb salvage compared to POBA. CONCLUSIONS Different forms of adjunctive vessel preparation demonstrate similar 12-month outcomes compared to POBA and DCB angioplasty alone in infrapopliteal disease, with the exception of improved 12-month limb salvage in scoring balloons and MA. However, since the included studies were heterogeneous and assessed as poor to moderate methodological quality, selection bias may have played an important role. Main conclusion is that this systematic review found no additional value of standard use of vessel preparation. CLINICAL IMPACT Infrapopliteal arterial disease is associated with chronic limb-threatening ischemia (CLTI) and generally complex to treat due to small vessel diameter, long lesion length, multilevel disease and severe calcification. A wide range of vessel preparation devices have been developed to contribute to improved peri- and postprocedural outcomes in these complex lesions. This systematic review aims to compare different vessel preparation techniques prior to plain old balloon angioplasty (POBA) or drug coated balloon (DCB) angioplasty with POBA or DCB angioplasty alone in infrapopliteal arterial disease. Different forms of adjunctive vessel preparation demonstrate similar 12-month outcomes compared to POBA and DCB angioplasty alone in infrapopliteal disease, with the exception of improved 12-month limb salvage in scoring balloons and mechanical atherectomy (MA). However, since the included studies were heterogeneous and assessed as poor to moderate methodological quality, selection bias may have played an important role. Main conclusion is that this systematic review found no additional value of standard use of vessel preparation.

Abstract
OBJECTIVE The article aimed to compare the efficiency and safety of atherectomy plus balloon angioplasty (BA) with BA alone for the treatment of infrapopliteal arterial disease. METHODS According to the inclusion and exclusion criteria, PubMed, Embase, and Cochrane Library database were searched for studies comparing atherectomy plus angioplasty and angioplasty alone in treating infrapopliteal artery lesions until November 2022. The endpoints included technical success, primary patency, clinically-driven target lesion revascularization (CD-TLR), periprocedural complications, distal embolization, target limb major amputation, and all-cause mortality. RESULTS Ten studies met the requirements of our meta-analysis, including 7723 patients in the atherectomy plus BA group and 2299 patients in the BA alone group. The meta-analysis showed that atherectomy plus BA was associated with reduced CD-TLR (odds ratio [OR]: 0.51, 95% confidence interval [CI]: 0.34, 0.78, p=0.002) and target limb major amputation (OR: 0.43, 95% CI: 0.19, 1.01, p=0.05) at 12-month follow-up. No statistically significant difference was found in technical success, primary patency, periprocedural complications, distal embolization, or all-cause mortality. Subgroup analysis found a higher rate of primary patency at 6 and 12 months (6 months: OR: 2.26, 95% CI: 1.11, 4.60, p=0.02; 12 months: OR: 2.38, 95% CI: 1.16, 4.86, p=0.02), and lower rates of CD-TLR (OR: 0.45, 95% CI: 0.25, 0.82, p=0.009) and target limb major amputation (OR: 0.43, 95% CI: 0.19, 1.01, p=0.05) at 12 months in patients treated with atherectomy plus drug-coated balloon (DCB) but not in patients treated with atherectomy plus plain old balloon angioplasty (POBA). CONCLUSIONS This meta-analysis suggests that compared with BA alone, atherectomy plus BA may reduce the need for CD-TLR and the incidence of target limb major amputation at 12-month follow-up in the treatment of infrapopliteal artery occlusive lesions, even though there are no significant advantages in technical success, primary patency, periprocedural complications, distal embolization, or all-cause mortality. To go further, atherectomy plus DCB shows significant benefits in primary patency, CD-TLR, and target limb major amputation rate but atherectomy plus POBA does not'. However, due to the limitations of this article, more randomized controlled trials (RCTs) are needed to confirm these conclusions. CLINICAL IMPACT According to our research, atherectomy combined with BA has the advantages of higher primary patency rate, lower CD-TLR and target limb significant amputation rate in treating infrapopliteal artery occlusive lesions, which may replace the current mainstream surgical method ---BA alone. For the clinician, although the surgery may take longer, it will significantly improve the prognosis and quality of life of patients and hold considerable significance for the management of patients with infrapopliteal arterial disease. Based on the characteristics of infrapopliteal artery disease, this study explored the feasibility of atherectomy combined with BA for infrapopliteal artery disease. Moreover, we found that atherectomy combined with DCB had better clinical efficacy, which should be the innovation of this study.

Abstract
INTRODUCTION Infra-popliteal peripheral arterial disease (IPPAD) poses challenges due to high restenosis and occlusion rates. The BASIL-2 trial demonstrated the superiority of endovascular treatment compared with surgical bypass in patients with IPPAD. However, the association between different endovascular modalities and clinical outcomes has not been conclusive. HYPOTHESIS Combining plain old balloon angioplasty (POBA) with atherectomy is associated with improved clinical outcomes compared with POBA alone. METHODS Patients who underwent POBA vs POBA+atherectomy for IPPAD from the Vascular Quality Initiative database were identified. To mitigate potential selection bias, we employed propensity score matching (PSM) to balance the distribution of confounding variables for mortality identified on multivariable logistic regression. Subsequently, we compared patient characteristics and long-term outcomes between the 2 treatment groups. RESULTS Among patients who underwent endovascular intervention for IPPAD, 19 979 individuals (80.8%) were treated with POBA alone, while 4747 (19.2%) were treated with both POBA+atherectomy after PSM. Propensity score matching ensured minimal differences in baseline characteristics, such as indication for lower extremity revascularization (LER) and history of LER. After PSM, patients receiving POBA+atherectomy experienced higher rates of technical success and lower perioperative complications, such as renal complications and hematoma, compared with POBA alone. During long-term follow-up, patients who underwent atherectomy had lower rates of major amputation and major adverse limb events (MALE) but slightly lower freedom from reintervention. Nonetheless, there were no differences in mortality. CONCLUSION Combining POBA with atherectomy appears to be a safe approach in patients with IPPAD, with lower rates of long-term amputation and MALE at the cost of a higher risk of reintervention. CLINICAL IMPACT The use of adjunctive atherectomy is associated with improved long-term outcomes in patients with infra-popliteal disease.

Abstract
PURPOSE Vessel calcification is estimated to be present in 30% to 50% of patients with peripheral arterial disease (PAD) and is one of the main challenges in endovascular treatment. The popliteal artery is unique compared with other arteries due to its exposure to significant deformation and biomechanical stress during knee motion. Intravascular lithotripsy (IVL) is a novel technique that uses acoustic pressure waves to cause microfractures within the intimal and medial wall calcification. Intravascular lithotripsy is safe in femoropopliteal and infrapopliteal lesions, but follow-up studies are lacking. Therefore, the purpose of this study was to describe the first follow-up outcomes of IVL in popliteal and infrapopliteal arterial disease. METHODS This prospective, multicenter cohort study included all patients treated with IVL in the popliteal and infrapopliteal arteries at 4 sites. Standardized follow-up with duplex ultrasonography was scheduled at 6 to 8 weeks and 12 months. The primary safety endpoint was a composite of major adverse events (MAEs) at 30 days. Primary efficacy endpoints were primary patency, limb salvage, and amputation-free survival (AFS) at 12 months. Secondary endpoints were primary-assisted patency and freedom from target lesion revascularization (TLR). Endpoints were distributed for patients with chronic limb-threatening ischemia (CLTI) and intermittent claudication (IC) and estimated using the Kaplan-Meier method. RESULTS Between April 2021 and March 2023, 29 patients with 30 limbs were treated. Diabetes mellitus (DM) and CLTI were present in 62.1% and 80.0% of patients, respectively. Within the 32 treated lesions, severe calcification was present in 84.4% and bailout stenting was necessary in 12.5% of the lesions. Four MAEs occurred within 30 days: 1 closure device failure, 1 major amputation, and 2 deaths, neither of which was related to the study device. The primary patency, primary-assisted patency, freedom from TLR, limb salvage, and AFS at 12 months were 68.8%, 90.0%, 93.3%, 83.9%, and 57.1% for CLTI patients, respectively. No events occurred in restenosis, re-occlusion, TLR, major amputation, or mortality in patients with IC. CONCLUSIONS This first-ever analysis on follow-up outcomes of IVL in the popliteal and infrapopliteal arteries demonstrated promising safety and efficacy outcomes with a low rate of bailout stenting. CLINICAL IMPACT Vessel calcification is a common feature in peripheral arterial disease (PAD) and is one of the main challenges in endovascular treatment. The popliteal artery is subjected to biomechanical stress during knee motion, which makes stenting unappealing and often leads to worse clinical outcomes. This study aimed to describe the first follow-up outcomes of IVL in popliteal and infrapopliteal arterial disease. As in line with previous studies, no relevant procedural complications were found and the rate of bail-out stenting was only 12.5%. Moreover, in a complex patient population, this study demonstrated promising safety and efficacy outcomes. The comparison of IVL with angioplasty alone or other vessel preparation devices for popliteal and infrapopliteal arterial disease is warranted.

Abstract
PURPOSE To compare procedural complications in patients undergoing atherectomy plus angioplasty (A+A) and plain balloon angioplasty (POBA). MATERIALS AND METHODS Patients in the Vascular Quality Initiative (VQI) registry undergoing first-time peripheral vascular intervention (PVI) were included. Those undergoing aortoiliac or pedal interventions, primary stenting, or hybrid procedures were excluded. Patients were stratified by lesion location (femoropopliteal [FP] or tibial [TIB]). The primary outcomes were target vessel dissection, distal embolization, and provisional stent placement. Secondary outcomes included postoperative complications and the need for subsequent interventions. RESULTS 12 499 patients undergoing FP (49.6% A+A) and 6736 patients undergoing TIB (17.0% A+A) interventions were identified. In the FP group, A+A was associated with greater intraoperative target vessel dissection (4.5% vs 2.6%, p<0.001), distal embolization (1.5% vs 0.7%, p =0.001), and provisional stent placement (1.5% vs 0%, p<0.001); and greater postoperative target vessel dissection (4.2% vs 2.0%, p<0.001) and distal embolization (0.9% vs 0.4%, p=0.034). In the TIB group, A+A was associated with fewer intraoperative vessel dissection (0.8% vs 2.3%, p=0.011) but greater provisional stent placement (0.3% vs 0%, p<0.001). TIB A+A was also associated with higher rates of technical success (97.6% vs 95.1%, p<0.001). CONCLUSIONS Atherectomy was associated with increased procedural-related complications in femoropopliteal, but not in tibial vessels. Future studies addressing lesion morphology, device design, and technique may help define its role in peripheral vascular interventions.

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
Objective We evaluated how contemporary data on infrapopliteal vessel preparation have been reported to identify knowledge gaps and opportunities for future research. Methods A literature search was performed on Web of Science, PubMed, and Google Scholar to identify clinical research studies reporting on the outcomes of vessel preparation in below-the-knee lesions between 2006 and 2021. Studies were excluded if they were case reports or case series with a sample size of <10. Results A total of 15 studies comprising 5450 patients were included in this review, with vessel preparation performed in 2179 cases (40%). Of the 15 studies, 2 were randomized controlled trials, 6 were prospective cohort studies, and 7 were retrospective studies. Only 2 of the 15 studies evaluated intravascular lithotripsy devices, and 6 were noncomparative studies. The mean diameter stenosis treated was 86.7% ± 12.6%, and the lesion length was 71.7 ± 55.3 mm. Large heterogeneity was found in the choice and definitions of end points and lesion characterization. Procedural success ranged between 84% and 90%, and bailout stenting was performed in 0.8% to 15% of cases. Of the five studies comparing procedural success of atherectomy with or without balloon angioplasty to balloon angioplasty alone, only one was in favor of the former (99% vs 90%; P < .001). The remaining studies did not show any statistically significant differences. Similarly, atherectomy had a significantly superior limb salvage rate in only one of seven studies (91% vs 73%; P = .036). In contrast, the seven studies evaluating target lesion revascularization reported conflicting outcomes, with two in favor of atherectomy, two against atherectomy, and three reporting similar outcomes between atherectomy and balloon angioplasty alone. None of the studies evaluating intravascular lithotripsy was comparative. Conclusions The current body of evidence on vessel preparation in tibial arteries is largely based on observational studies with a large amount of heterogeneity and a number of inconsistencies. Further clinical and experimental studies with more robust study designs are warranted to investigate the comparative efficacy and safety of vessel preparation in calcified tibial arteries.

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
OBJECTIVE We evaluated limb salvage (LS), amputation-free survival (AFS), and target extremity reintervention (TER) after plain old balloon angioplasty (POBA), stenting, and atherectomy for treatment of infrapopliteal disease (IPD) with chronic limb-threatening ischemia (CLTI). METHODS All index peripheral vascular interventions for IPD and CLTI were identified from the Vascular Quality Initiative registry. Of the multilevel procedures, the peripheral vascular intervention type was indexed to the infrapopliteal segment. Propensity score matching was used to control for baseline differences between groups. Kaplan-Meier and Cox regression were used to calculate and compare LS and AFS. RESULTS The 3-year LS for stenting vs POBA was 87.6% vs 81.9% (P = .006) but was not significant on Cox regression analysis (hazard ratio [HR], 0.91; 95% confidence interval [CI], 0.56-0.76; P = .08). AFS was superior for stenting vs POBA (78.1% vs 69.5%; P = .001; HR, 0.73; 95% CI, 0.60-0.90; P = .003). LS was similar for POBA and atherectomy (81.9% vs 84.8%; P = .11) and for stenting and atherectomy (87.6% vs 84.8%; P = .23). The LS rate after propensity score matching for POBA vs stenting was 83.4% vs 88.2% (P = .07; HR, 0.71; 95% CI, 0.50-1.017; P = .062). The AFS rate for stenting vs POBA was 78.8% vs 69.4% (P = .005; HR, 0.69; 95% CI, 0.54-0.89; P = .005). No significant differences were found between stenting and atherectomy (P = .21 for atherectomy; and P = .34 for POBA). The need for TER did not differ across the groups but the interval to TER was significantly longer for stenting than for POBA or atherectomy (stenting vs POBA, 12.8 months vs 7.7 months; P = .001; stenting vs atherectomy, 13.5 months vs 6.8 months; P < .001). CONCLUSIONS Stenting and atherectomy had comparable LS and AFS for patients with IPD and CLTI. However, stenting conferred significant benefits for AFS compared with POBA but atherectomy did not. Furthermore, the interval to TER was nearly double for stenting compared with POBA or atherectomy. These factors should be considered when determining the treatment strategy for this challenging anatomic segment.

Abstract
Endovascular treatment of peripheral arterial disease has evolved and expanded rapidly over the last 20 years. New technologies have increased the diversity of devices available and have made it possible to approach even the most challenging and high-risk lesions using endovascular techniques. In this review, we examine the clinical evidence available for several categories of endovascular devices available to treat peripheral arterial disease, including intravascular lithotripsy, atherectomy, and drug-coated devices. The best application for some technologies, such as intravascular lithotripsy and atherectomies, have yet to be identified. In contrast, drug-coated devices have an established role in patients at high risk for long-term failure, but have been the subject of much controversy, given recent concerns about possible adverse effects of paclitaxel. Future investigation should further assess these technologies in patients with complex disease using updated staging systems and outcomes with direct clinical relevance, such as functional improvement, wound healing, and freedom from recurrent symptoms.

Abstract
Background: Our aim was to review the current literature of the use of directional
atherectomy (DA) in the treatment of lower extremity critical-limb
ischemia. Methods: A search for relevant literature was performed in PubMed and PubMed Central
on 16 April 2020, sorted by best match. Three searches across two databases
were performed. Articles were included that contained clinical and
procedural data of DA interventions in lower extremity critical-limb
ischemia patients. All studies that were systematic reviews were
excluded. Results: Eleven papers were included in this review. Papers were examined under
several parameters: primary patency and secondary patency, limb
salvage/amputation, technical/procedural success,
complications/periprocedural events, and mean lesion length. Primary and
secondary patency rates ranged from 56.3% to 95.0% and 76.4% to 100%,
respectively. Limb salvage rates ranged from 69% to 100%. Lesion lengths
were highly varied, representing a broad population, ranging from 30 ± 33 mm
to 142.4 ± 107.9 mm. Conclusions: DA may be a useful tool in the treatment of lower extremity critical-limb
ischemia.

Abstract
INTRODUCTION To evaluate the current role of atherectomy techniques (ATH) in treatment of peripheral arterial disease (PAD) at below the knee (BTK) arteries. EVIDENCE ACQUISITION The PubMed and Embase were searched (last search on 11 September 2021) for studies reporting on the early and mid-term outcomes of ATH in BTK vessels. Analysis included the data from six studies, with a total of 1062 PAD patients treated with various ATH techniques. We compared them the ATH outcomes with the contemporaneous outcomes of plain balloon angioplasty alone or with bailout stenting. Early safety and efficacy were accessed with perioperative and 30-day technical success rate, which included the primary patency of the treated BTK arterial segment. Evaluation of clinical performance was based on target limb revascularization (TLR) and on major limb adverse events (MALEs) rates. EVIDENCE SYNTHESIS The current body of literature mainly includes retrospective observational studies, and the level of derived evidence is low. The mean perioperative and 30-day technical success rate was 87.3%. The mean reported TLR and MALEs rates at 12 months were 6.6% and 4.7% respectively. The relevant rates in studies reporting at 24 months were 24.3% and 31.7% while in studies reporting at 36 months the rates were 37.0% and 23.0% respectively. CONCLUSIONS Based in low-quality evidence, it seems that ATH in BTK vessels has a high safety, high efficacy profile and durable outcomes at 12 months. In the midterm, the clinical success of ATH is compromised by increased TLR and MALEs rates. Comparison of ATH with other endovascular techniques in BTK treatment of PAD shows a slight lead of ATH at 1-year and equivalent clinical performance in the mid-term. Overall, ATH has a significant and potentially predominant role in treatment of BTK vessels.

Abstract
BACKGROUND Patients with peripheral artery disease (PAD) present with claudication or chronic limb threatening ischemia (CLTI). CLTI patients have a more advanced stage of atherosclerosis and increased comorbidities compared to claudicants, and are at an elevated risk of major amputation and mortality after lower extremity revascularization (LER). However, the frequency of reinterventions for claudication and CLTI have not been compared. Our hypothesis is that patients with CLTI undergo more frequent reinterventions to prevent major amputation. METHODS A single-center retrospective chart review of consecutive patients undergoing lower extremity revascularization (LER) for PAD in 2013-2015 was performed. Patients were stratified based on indication for revascularization into claudication or CLTI. Patient characteristics, outcomes, and reinterventions were compared between the 2 groups. RESULTS There were 826 patients undergoing LER and 44% (N = 361) had CLTI. Patients treated for CLTI were more likely to be smokers (P < 0.001), to have diabetes (P< 0.001), chronic renal insufficiency (P< 0.001), end stage renal disease (P< 0.001), and cardiac disease (P< 0.001). CLTI patients were less likely to be on optimal medical management as reflected by decreased rate of aspirin (P< 0.001), ADP receptor/P2Y12 inhibitors (P< 0.001), and statins (P< 0.001) compared to patients with claudication. Patients with CLTI had significantly higher major amputation (3.7% vs. 0.2%, P< 0.001) and mortality (1.4% vs. 0.2%, P = 0.092) at 30 days. At long-term follow up, patients with CLTI had higher rates of major amputation (15.5% vs. 1.3%, P < 0.001) and mortality (37.1% vs. 18.1%, P < 0.001) compared to patients with claudication. There was a significant difference in mean follow-up time between the 2 cohorts (claudication: 3.7 ± 1.5 years versus CLTI: 2.6 ± 1.8 years, P < 0.001). There was no significant difference in the ipsilateral reintervention rate between the 2 groups (claudication: 39.6% vs. CLTI: 42.7%, P = 0.37) or the mean number of ipsilateral reinterventions (claudication: 2.0 ± 1.6 vs. CLTI: 2.0 ± 1.7). However, after adjusting for follow-up time, the mean number of reinterventions per year was significantly higher for CLTI patients compared to patients with claudication (1.4 ± 2.2 vs. .6 ± 0.7 intervention per year, P < 0.001). CONCLUSIONS Patients undergoing LER for CLTI undergo more frequent reinterventions over time compared to patients treated for claudication. Research on reinterventions after LER should include reporting of the frequency of reintervention adjusted for the follow up period in addition to the reintervention rate defined as the percentage of patients undergoing reintervention.

J Vasc Surg 2021; 75:697-708.e9.

Abstract
OBJECTIVE Atherectomy has become increasingly used as an endovascular treatment of lower extremity atherosclerotic disease in the United States. Concerns and controversies about its indication and outcomes exist. The goal of this systematic review and meta-analysis was to investigate the outcomes and complications related to atherectomy to treat femoropopliteal atherosclerotic disease. METHODS A systematic review following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was performed. Four major scientific repositories, MEDLINE, EMBASE, The Cochrane Library, and Thompson Web of Sciences were queried from their inception to April 5, 2020. Data was reviewed and entered in a dedicated dataset by the investigators. Outcomes included patency rates, clinical and hemodynamic improvement, and morbidity and mortality associated with atherectomy interventions. RESULTS Twenty-four studies encompassing 1900 patients met inclusion criteria for this study. 74.3% of patients presented with Rutherford class (RC) 1-3 and 25.7% presented with RC class 4-6. 1445 patients underwent atherectomy, and 455 patients were treated without atherectomy. Atherectomy patients underwent directional atherectomy (DA, n = 851), rotational atherectomy (RA, n = 851), laser atherectomy (LA, n = 201), and orbital atherectomy (OA, n = 78). The majority of patients additionally received adjunct treatments which were variable across studies and included a combination of stenting, balloon angioplasty (BA), or drug coated balloon (DCB) angioplasty. Technical success was achieved in 92.3% of cases. Distal embolization, vessel perforation, and dissection occurred in 3.4%, 1.9%, and 4% of cases respectively. Initial patency was 95.4% and at 12-month median follow up primary patency was 72.6%. ABI improved from pre-operative mean of 0.6 to post-operative mean of 0.84. Incidence of major amputation and mortality over the follow up period was 2.2% and 3.4% respectively. CONCLUSIONS This review of the published data suggests that femoropopliteal atherectomy can be completed safely while modestly improving ABIs and maintaining one-year patency in nearly three out of four patients; however, this is based on heterogeneous studies that skew generalizable conclusions about atherectomy's efficacy. Atherectomy places a high cost burden on the healthcare system and is utilized in the United States at a higher rate than in other countries. Our review of the literature does not demonstrate clear atherectomy superiority to alternatives that would warrant pervasive and increasing use of this costly technology. Future work should focus on developing high quality randomized controlled trials to determine specific patient and lesion characteristics in which atherectomy can add value.

Abstract
PURPOSE Restenosis remains a limitation of endovascular angioplasty with a patency of 30% in BTK at 12 months. Several studies on drug-coated balloons have not demonstrated any improvements in terms of patency and target lesions revascularization in BTK lesions. This prospective single-centre cohort study evaluates the safety and efficacy of a new generation low-dose drug-coated balloon (DCB) with a reduced crystalline structure to treat below the knee (BTK) lesions in patients with critical limb ischemia (CLI). MATERIALS AND METHODS Between November 2016 and November 2017, 30 consecutive patients (mean 68.8 ± 12.7 years, 6 female) with BTK lesions and CLI were included in this single-centre, prospective non-randomized cohort study. All patients with rest pain and/or ischemic wound associated with BTK lesions were included in the study. Mean lesion length was 133.6 ± 94.5 mm and 18(60%) were chronic total occlusions. The primary safety outcome parameter was a composite of all-cause mortality and major amputation at 6 months. The primary efficacy outcome parameter was the primary angiographic patency at 6 months (defined as freedom from clinically driven target lesion revascularization and the absence of significant restenosis (> 50%) as determined by core laboratory angiography assessment. Immediate technical success, late lumen loss (LLL), clinical target lesion revascularization (TLR) and ulcer healing rates at 12 months were also evaluated. RESULTS Immediate technical success was 97%(29/30): one patient had an acute thrombosis at the completion of index procedure. Primary safety outcome parameter was 94%(28/30): one patient underwent major amputation and one patient died of other comorbidities at 2 months. Another patient had a major amputation at 7.5 months. Angiographic follow-up was available in 20 patients. Primary angiographic patency was 57%(12/21 lesions), and LLL was 0.99 ± 0.68 mm at 6 months. Freedom from TLR was 89% at 12 months. The rate of ulcer healing was 76% at 12 months. CONCLUSION Ranger DCB balloons to treat CLI patients demonstrated a positive trend with good safety outcomes parameters. Further randomized studies are needed to understand the usefulness compared to POBA.

Abstract
This meta-analysis aimed to evaluate the device performance of conventional balloon catheters (POBA), drug-coated balloons (DCB), bare-metal stents (BMS), and drug-eluting stents (DES) in below-the-knee (BTK) ischemic lesions with regard to lesion characteristics. Online searches of PubMed, Web of Science, and Cochrane databases (2010–2019) were conducted for each of the test devices. Primary patency rates (pp) and major amputation rates 1 year after the use of each device were analyzed using a random-effects meta-analysis model. Meta-regression analysis was conducted to test associations between the outcomes and lesion characteristics. The analysis included 18 studies reporting on 24 separate cohorts comprising 2,438 patients. DES demonstrated the best pp among the test devices (83.6%; 95% confidence interval = 78.4–88.8%, studies = 8; I2 = 66%, P = 0.005). A negative coefficient between lesion length and pp (P = 0.002) was obtained. The ratio of critical limb ischemia (CLI) patients impacted the amputation rates (P = 0.031), whereas no statistically significant difference was found between the devices. DES showed favorable pp in BTK lesions; however, as the lesion lengths using DES were short, pp in long lesions still needs to be evaluated. Shorter lesions gained better pp. A higher ratio of CLI patients resulted in increased amputation rates.

Abstract
INTRODUCTION The past 25 years have been witness to a revolution in how vascular care is delivered. The majority of arterial and venous interventions have converted from open surgery to minimally invasive percutaneous endovascular procedures. METHODS This surgical innovations symposium article reviews current endovascular therapy in multiple vascular beds with a primary focus on carotid artery occlusive disease, aortic pathologies, and lower extremity arterial occlusive disease. Mesenteric arterial occlusive disease and lower extremity venous endovascular therapies are also briefly discussed. Indications for intervention, treatment examples and outcomes analysis are presented. While not reviewed in this article, endovascular therapy has also become first line in the treatment of coronary artery disease, chronic mesenteric arterial occlusive disease, superficial venous reflux, central vein occlusion, and acute venous thrombus intervention when indicated. CONCLUSION Endovascular therapies are used in all vascular beds to treat the full spectrum of vascular pathologies. Aneurysm disease, atherosclerotic arterial occlusive disease, acute arterial and venous thrombosis, ongoing hemorrhage, and venous reflux are among the issues which can be addressed by endovascular means. The minimally invasive nature of endovascular treatments in what is largely a very co-morbid patient cohort is an attractive method of avoiding major procedural related morbidity and mortality.

Abstract
OBJECTIVES To compare perioperative outcomes related to atherectomy with percutaneous transluminal angioplasty versus percutaneous transluminal angioplasty alone for the treatment of lower extremity chronic limb threatening ischemia using a national patient database. METHODS Patients with chronic limb threatening ischemia treated with atherectomy and percutaneous transluminal angioplasty or percutaneous transluminal angioplasty alone from 2011 to 2016 in the National Surgical Quality Improvement Program database were identified. Primary outcomes were major adverse limb events (30-day untreated loss of patency, major reintervention, major amputation) and major adverse cardiac events (cardiac arrest, composite outcome of myocardial infarction or stroke). Secondary outcomes included 30-day mortality, length of stay, and any unplanned readmission within 30 days. Multivariate regression analyses were performed to determine independent predictors of outcome. Propensity score matched cohort analysis was performed. A p-value <0.05 was considered statistically significant. Subgroup analyses of femoropopliteal and infrapopliteal interventions were performed. RESULTS In total, 2636 (77.2%) patients were treated with percutaneous transluminal angioplasty and 778 (22.8%) were treated with atherectomy and percutaneous transluminal angioplasty. Multivariate analyses of the unadjusted cohort revealed no significant differences in major adverse cardiac events or major adverse limb events between the two groups (p-value >0.05). Subgroup analysis of femoropopliteal interventions demonstrated a significantly decreased likelihood of untreated loss of patency in 30 days in the atherectomy group compared to the percutaneous transluminal angioplasty group (1.1% vs. 2.7%, respectively; p-value = 0.034), which persisted on propensity score matched analysis (1.1% vs. 3.1%, respectively; p-value = 0.026). CONCLUSION Atherectomy with balloon angioplasty of femoropopliteal disease provides a significant decrease in untreated loss of patency compared to balloon angioplasty alone.

Abstract
OBJECTIVE Limited data exist comparing atherectomy (At) with balloon angioplasty for infrapopliteal peripheral arterial disease. The objective of this study was to compare the outcomes of infrapopliteal At with angioplasty vs angioplasty alone in patients with critical limb ischemia. METHODS This is a retrospective, single-center, longitudinal study comparing patients undergoing either infrapopliteal At with angioplasty or angioplasty alone for critical limb ischemia, between January 2014 and October 2017. The primary outcome was primary patency rates. Secondary outcomes were reintervention rates, assisted primary patency, secondary patency, major adverse cardiac events, major adverse limb events, amputation-free survival, overall survival, and wound healing rates. Data were analyzed in multivariate generalized linear models with log rank tests to determine survival in Kaplan-Meier curves. RESULTS There were 342 infrapopliteal interventions, 183 percutaneous balloon angioplasty (PTA; 54%), and 159 atherectomies (At) with PTA (46%) performed on 290 patients, with a mean age of 67 ± 12 years; 61% of the patients were male. The PTA and At/PTA groups had similar demographics, tissue loss (79% vs 84%; P = .26), ischemic rest pain (21% vs 16%; P = .51), mean follow-up (19 ± 9 vs 20 ± 9 months; P = .32), mean number of vessels treated (1.7 ± 0.8 vs 1.9 ± 0.8; P = .08) and the mean lesion length treated (6.55 ± 5.00 cm vs 6.02 ± 4.00 cm; P = .08), respectively. Similar 3-month (96 ± 1% vs 94 ± 1%), 6-month (85 ± 2% vs 86 ± 3%), 12-month (68 ± 3% vs 69 ± 4%), and 18-month (57 ± 4% vs 62 ± 4%) primary patency rates were seen in the two groups (P = .87). At/PTA patients had significantly higher reintervention rates as compared with the PTA patients (28% vs 16%; P = .02). Similar assisted primary patency rates (67 ± 4% vs 69 ± 4%; P = .78) and secondary patency rates (61 ± 4% vs 66 ± 4%; P = .98) were seen in the PTA and At/PTA groups at 18 months. The 30-days major adverse cardiac event rates (3% vs 2%; P = .13) and 30-day major adverse limb event rates (5% vs 4%; P = .2) were similar in both groups. Wound healing rates (72 ± 3% vs 75 ± 2%; P = .12), 1-year amputation-free survival (68 ± 4.1% vs 70 ± 2%; P = .5), and 1-year overall survival (76 ± 4% vs 78 ± 4%; P = .39) rates did not differ in the PTA and At/PTA groups. THE At/PTA group had higher local complication rates (7 [4%] vs 1 [0.5%]; P = .03) CONCLUSIONS: At with angioplasty provides similar patency rates compared with angioplasty alone for infrapopliteal peripheral arterial disease, but associated with higher reintervention and local complication rates. Further appropriately designed studies are required to determine the exact role of At in this subset of patients.

Abstract
GUIDELINE SUMMARY Chronic limb-threatening ischemia (CLTI) is associated with mortality, amputation, and impaired quality of life. These Global Vascular Guidelines (GVG) are focused on definition, evaluation, and management of CLTI with the goals of improving evidence-based care and highlighting critical research needs. The term CLTI is preferred over critical limb ischemia, as the latter implies threshold values of impaired perfusion rather than a continuum. CLTI is a clinical syndrome defined by the presence of peripheral artery disease (PAD) in combination with rest pain, gangrene, or a lower limb ulceration >2 weeks duration. Venous, traumatic, embolic, and nonatherosclerotic etiologies are excluded. All patients with suspected CLTI should be referred urgently to a vascular specialist. Accurately staging the severity of limb threat is fundamental, and the Society for Vascular Surgery Threatened Limb Classification system, based on grading of Wounds, Ischemia, and foot Infection (WIfI) is endorsed. Objective hemodynamic testing, including toe pressures as the preferred measure, is required to assess CLTI. Evidence-based revascularization (EBR) hinges on three independent axes: Patient risk, Limb severity, and ANatomic complexity (PLAN). Average-risk and high-risk patients are defined by estimated procedural and 2-year all-cause mortality. The GVG proposes a new Global Anatomic Staging System (GLASS), which involves defining a preferred target artery path (TAP) and then estimating limb-based patency (LBP), resulting in three stages of complexity for intervention. The optimal revascularization strategy is also influenced by the availability of autogenous vein for open bypass surgery. Recommendations for EBR are based on best available data, pending level 1 evidence from ongoing trials. Vein bypass may be preferred for average-risk patients with advanced limb threat and high complexity disease, while those with less complex anatomy, intermediate severity limb threat, or high patient risk may be favored for endovascular intervention. All patients with CLTI should be afforded best medical therapy including the use of antithrombotic, lipid-lowering, antihypertensive, and glycemic control agents, as well as counseling on smoking cessation, diet, exercise, and preventive foot care. Following EBR, long-term limb surveillance is advised. The effectiveness of nonrevascularization therapies (eg, spinal stimulation, pneumatic compression, prostanoids, and hyperbaric oxygen) has not been established. Regenerative medicine approaches (eg, cell, gene therapies) for CLTI should be restricted to rigorously conducted randomizsed clinical trials. The GVG promotes standardization of study designs and end points for clinical trials in CLTI. The importance of multidisciplinary teams and centers of excellence for amputation prevention is stressed as a key health system initiative.

Abstract
Background The long-term effectiveness of atherectomy treatment for peripheral arterial disease is unknown. We studied 5-year clinical outcomes by endovascular treatment type among patients with peripheral arterial disease. Methods and Results We queried the Medicare-linked VQI (Vascular Quality Initiative) registry for endovascular interventions from 2010 to 2015. The exposure was treatment type: atherectomy (with or without percutaneous transluminal angioplasty [ PTA] ), stent (with or without PTA ), or PTA alone. The outcomes were major amputation, any amputation, and major adverse limb event (major amputation or any reintervention). We used the center-specific proportions of atherectomy procedures performed in the 12 months before a patient's procedure as the instruments to perform an instrumental-variable Cox model analysis. Among 16 838 eligible patients (median follow-up: 1.3-1.5 years), 11% underwent atherectomy, 40% received PTA alone, and 49% underwent stenting. Patients receiving atherectomy commonly underwent femoropopliteal artery treatment (atherectomy: 65%; PTA : 49%; stenting: 43%; P<0.001) and had worse disease severity (Trans-Atlantic Inter-Society Consensus score [TASC] B and greater; atherectomy: 77%; PTA : 68%; stenting: 67%; P<0.001). The 5-year rate of major adverse limb events was 38% in patients receiving atherectomy versus 33% for PTA and 32% for stenting (log rank P<0.001). Controlling for unmeasured confounding using instrumental-variable analysis, patients treated with atherectomy experienced outcomes similar to those of patients treated with PTA , except for a higher risk of any amputation (hazard ratio: 1.51; 95% CI , 1.08-2.13). However, compared with stenting, atherectomy patients had a higher risk of major amputation (hazard ratio: 3.66; 95% CI , 1.72-7.81), any amputation (hazard ratio: 2.73; 95% CI , 1.60-4.76), and major adverse limb event (hazard ratio: 1.61; 95% CI , 1.10-2.38). Conclusions Atherectomy is used to treat severe femoropopliteal and tibial peripheral arterial disease even though long-term adverse outcomes occur more frequently after this treatment modality.

Abstract
BACKGROUND Use of atherectomy for the treatment of peripheral arterial disease (PAD) is increasing as an adjunctive treatment to either conventional or drug-coated balloon angioplasty. There is limited data on atherectomy outcomes in below-the-knee (BTK) endovascular interventions. METHODS Data from the multicenter Excellence in Peripheral Artery Disease (XLPAD) registry (NCT01904851) were analyzed to examine predictors of atherectomy use and its associated 1-year patency rate. We analyzed 518 BTK procedures performed between January 2005 and December 2016. RESULTS Overall a total of 518 BTK procedures were treated in 430 patients, and 43% of interventions used atherectomy. African American patients were less likely (13% vs 25%; |standard residual| = 3.41) to be treated with atherectomy. Use of atherectomy was lower in chronic total occlusive (CTO) lesions (48% vs 58%; P = 0.02). There were no significant associations of baseline comorbidities, critical limb ischemia (CLI), ankle-brachial index, number of BTK vessel run-off, or vessel location with atherectomy use. Compared with patients without atherectomy, use of atherectomy was associated with lower incidence of repeat target limb intervention at 1 year after adjusting for age, CLI, in-stent restenosis, heavy calcification, presence of diffuse disease, and CTO lesion traits (Hazard Ratio 0.41, 95% confidence interval 0.23-0.72; P < 0.01). CONCLUSIONS Compared with no atherectomy, use of atherectomy in BTK interventions is associated with lower rates of 1-year repeat target limb revascularization. These findings require confirmation in prospective, randomized clinical studies.

Abstract
Purpose: To compare outcomes of outpatient tibial artery procedures between an office endovascular center and a hospital angiography suite. Methods: A retrospective review was conducted of 204 outpatient tibial interventions performed on 161 patients (mean age 72±11.5 years; 81 men) in either an office (n=100) or hospital (n=104) angiography suite from April 2011 through September 2013. Patients who had an existing ipsilateral bypass that was completely proximal to the tibial trifurcation were eligible, as were patients with prior proximal endovascular interventions. Exclusion criteria included previous ipsilateral bypass involving the infrapopliteal vessels, in-patient status at the time of the procedure, planned admission after the procedure, and infrapopliteal stenting. Treatment included percutaneous transluminal angioplasty (PTA) or PTA with atherectomy. Primary outcomes were unplanned admission, emergency room visits, acute complications, and patency. Results: There were no significant differences in demographics or baseline Rutherford category between patients treated in an office endovascular suite vs a hospital angiography suite. Factors more prevalent in the hospital group included chronic obstructive pulmonary disease (16% vs 8%, p=0.045), renal insufficiency (37% vs 25%, p=0.017), and previous proximal bypass (12% vs 4%, p=0.045). Of the 100 office procedures, 25 involved PTA and 75 were PTA with atherectomy, while in the 104 hospital procedures, PTA was applied in 68 patients and PTA with atherectomy in 36. Thirty-day local complication rates (7% vs 11%, p=0.368), systemic complication rates (4% vs 8%, p=0.263), and mortality (1% vs 2%, p=0.596) in the office vs hospital setting were not statistically different. Unplanned postprocedure hospital admission rates for medical reasons were lower in the office group (2% vs 11%, p=0.01). Kaplan-Meier estimates of the 1-year follow-up data were better in the office group for primary patency (69% vs 53%, p=0.050), assisted primary patency (90% vs 89%, p=0.646), and amputation-free survival (89% vs 83%, p=0.476), but the differences were not statistically significant. Conclusion: Efficacy and safety of outpatient endovascular tibial artery interventions between office and hospital settings were similar, with lower unplanned admission rates and better patency. With appropriate patient selection, the office endovascular suite can be a safe alternative to the hospital angiography suite.

Abstract
OBJECTIVE Peripheral atherectomy has been shown to have technical success in single-arm studies, but clinical advantages over angioplasty and stenting have not been demonstrated, leaving its role unclear. We sought to describe patterns of atherectomy use in a real-world U.S. cohort to understand how it is currently being applied. METHODS The Vascular Quality Initiative was queried to identify all patients who underwent peripheral vascular intervention from January 2010 to September 2016. Descriptive statistics were performed to analyze demographics of the patients, comorbidities, indication, treatment modalities, and lesion characteristics. The intermittent claudication (IC) and critical limb ischemia (CLI) cohorts were analyzed separately. RESULTS Of 85,605 limbs treated, treatment indication was IC in 51% (n = 43,506) and CLI in 49% (n = 42,099). Atherectomy was used in 15% (n = 13,092) of cases, equivalently for IC (15%; n = 6674) and CLI (15%; n = 6418). There was regional variation in use of atherectomy, ranging from a low of 0% in one region to a high of 32% in another region. During the study period, there was a significant increase in the proportion of cases that used atherectomy (11% in 2010 vs 18% in 2016; P < .0001). Compared with nonatherectomy cases, those with atherectomy use had higher incidence of prior peripheral vascular intervention (IC, 55% vs 43% [P < .0001]; CLI, 47% vs 41% [P < .0001]), greater mean number of arteries treated (IC, 1.8 vs 1.6 [P < .0001]; CLI, 2.1 vs 1.7 [P < .0001]), and lower proportion of prior leg bypass (IC, 10% vs 14% [P < .0001]; CLI, 11% vs 17% [P < .0001]). There was lower incidence of failure to cross the lesion (IC, 1% vs 4% [P < .0001]; CLI, 4% vs 7% [P < .0001]) but higher incidence of distal embolization (IC, 1.9% vs 0.8% [P < .0001]; CLI, 3.0% vs 1.4% [P < .0001]) and, in the CLI cohort, arterial perforation (1.4% vs 1.0%; P = .01). CONCLUSIONS Despite a lack of evidence for atherectomy over angioplasty and stenting, its use has increased across the United States from 2010 to 2016. It is applied equally to IC and CLI populations, with no identifiable pattern of comorbidities or lesion characteristics, suggesting that indications are not clearly delineated or agreed on. This study places impetus on further understanding of the optimal role for atherectomy and its long-term clinical benefit in the management of peripheral arterial disease.

Abstract
Traditional percutaneous balloon angioplasty and stent placement is based on mechanical plaque disruption and displacement within the arterial wall. On the contrary, transcatheter atherectomy achieves atherosclerotic plaque clearance by means of directional plaque excision or rotational plaque removal or laser plaque ablation. Debulking atherectomy may allow for a more uniform angioplasty result at lower pressures with consequently less vessel barotrauma and improved luminal gain, thereby decreasing the risk of plaque recoil and dissection that may require permanent metal stenting. It has been also argued that atherectomy may disrupt the calcium barrier and optimize drug transfer and delivery in case of drug-coated balloon applications. The authors discuss the various types of atherectomy devices available in clinical practice to date and critically appraise their mode of action as well as relevant published data in each case. Overall, amassed randomized and observational evidence indicates that percutaneous atherectomy of the femoropopliteal and infrapopliteal arteries may achieve high technical success rates and seems to lessen the frequency of bailout stenting, however, at the expense of increased risk of peri-procedural distal embolization. Long-term clinical outcomes reported to date do not support the superiority of percutaneous atherectomy over traditional balloon angioplasty and stent placement in terms of vessel patency or limb salvage. The combination of debulking atherectomy and drug-coated balloons has shown promise in early studies, especially in the treatment of more complex lesions. Unanswered questions and future perspectives of this continuously evolving endovascular technology as part of a broader treatment algorithm are discussed.

Abstract
BACKGROUND The aim of the study was to investigate the clinical results of laser atherectomy in the treatment of peripheral arterial disease. METHODS Retrospective analysis of consecutive patients underwent laser atherectomy at a single institution during a 7-year period by vascular surgeons and interventional cardiologists in a tertiary university-affiliated hospital. Clinical data were retrieved from patient charts and hospital electronic medical records along with the associated arteriograms. RESULTS A total of 461 lesions in 343 limbs were treated in 300 patients with a mean age of 70 years. The indication was critical limb ischemia (CLI) with rest pain or tissue loss in 227 (66%) of interventions and claudication in 116 (34%). All procedures included an associated balloon angioplasty, while stenting was performed in 33%. Technical success was achieved in 99% with only 2 (<1%) cases with an acute procedure-related complication requiring surgical intervention. At a mean follow-up of 28 months (range, 1-87 months; median 24 months), 156 patients (45%) became asymptomatic or achieved significant clinical improvement (resolution of tissue loss or rest pain), 60 (17%) remained with CLI, 30 (9%) had a major proximal amputation, and 18 (5%) had a minor amputation. Freedom from major amputation was 90% at 5 years by life-table analysis. Univariate statistical analysis demonstrated the risk of a major amputation to be associated with diabetes, hemodialysis, and tissue loss (P < 0.05 to P < 0.005), while multivariate logistic regression analysis indicated diabetes to be overwhelmingly important (RR: 4.84; 95% confidence interval [CI]: 1.1-21.3; P < 0.05). In a similar manner, multivariate analysis indicated dialysis (RR: 2.46; 95% CI: 1.01-5.98; P < 0.05) and CLI (RR: 2.27; 95% CI: 1.42-3.65; P < 0.01) were associated with higher likelihood for lack of clinical improvement. There was no difference in major amputation rates between surgeons and interventional cardiologists (RR: 1.5; 95% CI: 0.7-2.1; P < 0.1) although it was 3 times more likely for the patients treated by surgeons to suffer from CLI (odds ratio: 3.2; 95% CI: 1.9-5.4; P < 0.0001). CONCLUSIONS Laser atherectomy is a safe and useful adjunct in limb salvage. Diabetics have much higher probability of requiring a proximal amputation, while those on dialysis and with CLI are least likely to gain clinical benefit.

Abstract
Critical limb ischemia (CLI) remains a significant cause of morbidity and mortality in patients with peripheral arterial disease. Optimal treatment strategies for CLI remain controversial. The only randomized trial comparing surgical with endovascular revascularization suggests no significant difference in limb salvage between open surgical bypass and angioplasty. Although novel endovascular strategies are now available, their efficacies remain largely untested in a randomized fashion. This review provides an overview of the data surrounding contemporary outcomes of endovascular therapy with an emphasis on current knowledge gaps.

Abstract
Peripheral atherectomy is a class of procedures that is rapidly increasing in volume. Multiple classes of devices exist, and newer variants are added to the market annually. The devices see wide application for de novo lesions, in-stent restenosis, and adjunctive therapy for drug-coated balloons. The body of evidence supporting atherectomy is less robust than for many other peripheral therapies. The frequency and severity of complications from atherectomy can be significant compared with angioplasty and stenting, and familiarity with preventative and bailout techniques is essential for the interventionalist.

Abstract
The confluence of several chronic conditions--in particular ageing, peripheral artery disease, diabetes, and chronic kidney disease--has created a global wave of lower limbs at risk for major amputation. While frequently asymptomatic or not lifestyle limiting, at least 1% of the population has peripheral artery disease of sufficient severity to be limb threatening. To avoid the critical error of failing to diagnose ischaemia, all patients with diabetic foot ulcers and gangrene should routinely undergo physiologic evaluation of foot perfusion. Ankle brachial index is useful when measurable, but may be falsely elevated or not obtainable in as many as 30% of patients with diabetic foot ulcers primarily because of medial calcinosis. Toe pressures and skin perfusion pressures are applicable to such patients.

Abstract
BACKGROUND The aim of this study was to evaluate the outcome of tapered balloon use in recanalization of long occlusions of below-the-knee (BTK) arteries in diabetic patients with critical limb ischemia (CLI). METHODS Forty-nine occluded BTK arteries in 35 diabetic patients with CLI were revascularized in our Diabetic Foot Center between January and September 2014 using tapered balloons. Twelve-month outcomes were evaluated in terms of healing of the lesions, survival, limb salvage, primary patency, primary assisted patency, and secondary patency. RESULTS The patients were predominantly male (27/35, 77.1%) with a mean age of 70.9 years (±10.3 standard deviation [SD]). During the follow-up (mean duration 12.4 months ± 4 SD), healing of the lesions was obtained in 27 of the 35 cases (77.1%). Estimated 12-month survival and limb salvage were 85.7% and 91.1%, respectively. Estimated 12-month primary patency, primary assisted patency, and secondary patency were 78.3%, 79%, and 88.9%, respectively. Univariate analysis demonstrated that the presence of chronic renal failure affected survival (P = 0.005), and assignment to Rutherford class 6 affected limb salvage (P = 0.005), primary patency (P < 0.001), and primary assisted patency (P < 0.001). Furthermore, the presence of coronary artery disease affected primary patency (P = 0.001) and primary assisted patency (P = 0.05). CONCLUSIONS Tapered balloons are a safe and effective means to recanalize long occlusions of BTK arteries in diabetic patients with CLI. Outcomes are poorer in patients with major tissue loss and with a history of coronary artery disease. Further experience with larger groups is needed to validate these outcomes.

Abstract
Critical limb ischemia (CLI) is the most severe and debilitating form of peripheral arterial disease and is associated with high rates of limb loss and cardiovascular mortality. The unique physical environment of tibial occlusive disease underlying most CLI cases limits treatment options and long-term durability, with resulting frequent rates of persistent obstruction, restenosis, and reintervention. Atherectomy represents a potential strategy to improve acute and late results when treating patients with CLI. Available atherectomy devices each have specific performance characteristics, evidentiary rationale, and limitations that mandate a clear understanding of the optimal albeit evolving use of this category of interventional tools.

Abstract
Vascular calcification (VC), particularly medial (Mönckeberg's medial sclerosis) arterial calcification, is common in patients with diabetes mellitus and chronic kidney disease and is associated with increased cardiovascular morbidity and mortality. Although, the underlying pathophysiological mechanisms and genetic pathways of VC are not fully known, hypocalcemia, hyperphosphatemia, and the suppression of parathyroid hormone activity are central to the development of vessel mineralization and, consequently, bone demineralization. In addition to preventive measures, such as the modification of atherosclerotic cardiovascular risk factors, current treatment strategies include the use of calcium-free phosphate binders, vitamin D analogs, and calcium mimetics that have shown promising results, albeit in small patient cohorts. The impact of intimal and medial VC on the safety and effectiveness of endovascular devices to treat symptomatic peripheral arterial disease (PAD) remains poorly defined. The absence of a generally accepted, validated vascular calcium grading scale hampers clinical progress in assessing the safety and utility of various endovascular devices (e.g., atherectomy) in treating calcified vessels. Accordingly, we propose the peripheral arterial calcium scoring system (PACSS) and a method for its clinical validation. A better understanding of the pathogenesis of vascular calcification and the development of optimal medical and endovascular treatment strategies are crucial as the population ages and presents with more chronic comorbidities.
