Abstract
OBJECTIVE The purpose of this study is to compare the initial outcomes of using the Chocolate balloon pre-dilatation (CLP) and sequential enlarging angioplasty pre-dilatation (sequential balloon pre-dilation [SP]) techniques versus the conventional balloon pre-dilatation (CP) method prior to drug-coated balloon (DCB) treatment for femoropopliteal (FP) lesions. METHODS This was a retrospective analysis of prospectively collected data from the CIVILIAN (Clinical InVestigation of different lesIon preparation modaLIty followed by DCB in femoropopliteal Artery occlusioN disease) registry. Between March 2021 and November 2022, 3 pre-dilation techniques used prior to the DCB angioplasty were included. The study endpoint included intraoperative finial severe dissection after provisional stent placement, bailout stenting rate, the diameter of the largest pre-dilation balloon and DCB, as well as major adverse events (MAEs), including death, major limb amputation, or target vessel revascularization at 6 months. RESULTS During the study period, 435 limbs (429 patients) were pre-dilated before DCB treatment in FP lesions, 166 limbs were pre-dilated with Chocolate balloons, 93 limbs with sequential enlarging balloon pre-dilation technique, and 176 limbs with CP. The largest pre-dilation balloon was significantly larger in CLP and SP groups than that in the CP group (CLP 4.74±0.52 mm vs CP 4.36±0.64 mm, p<0.001; SP 4.82±0.69 mm vs CP 4.36±0.63 mm, p<0.001). A consistent result was shown in DCB diameter (CLP 4.86±0.44 mm vs CP 4.71±0.51 mm, p=0.003; SP 4.90±0.58 mm vs CP 4.71±0.51 mm, p=0.006). The bailout stenting rate was significantly lower in the CLP group than that in the CP group (18.1% vs 30.1%, p=0.011). The rates of MAEs at 6 months in the CLP and SP groups were comparable to those in the CP group (7.2% and 8.6% vs 6.3%, p>0.05). The risk for intraoperative bailout stenting rate was related to TASC D classification (3.59, 95% CI: 1.83-7.05, p<0.001), chronic total occlusion (CTO) lesion (1.82, 95% CI: 1.07-3.10, p=0.028), as well as pre-dilated with the conventional balloon (1.64, 95% CI: 1.00-2.69, p=0.048). CONCLUSIONS By utilizing chocolate balloon and sequential enlarging angioplasty, it becomes possible to use larger pre-dilation balloons and DCBs. In addition, the use of the chocolate balloon can significantly reduce the need for bailout stenting when compared with conventional balloons. CLINICAL IMPACT The utilization of a chocolate balloon and sequential enlarging angioplasty has emerged as a promising technique for angioplasty procedures. This approach allows for the use of larger pre-dilation balloons and drug-coated balloons. The use of the chocolate balloon can significantly reduce the need for bail-out stenting when compared to conventional balloons. Further research is required to determine the impact of vessel preparation techniques on the primary patency.

Abstract
OBJECTIVE Indications for endovascular treatment of femoropopliteal (FP) lesions have steadily increased over the past decade. Accordingly, the number of devices has also increased but the choice of the best endovascular treatment remains to be defined. The aim of this meta-analysis was to summarize all studies investigating endovascular treatment of FP lesions greater than 150 mm from 2010 to 2021. METHODS Articles were searched using PubMed, Scopus, and Cochrane. Included studies were randomized controlled trials (RCTs), cohort studies, and case series (prospective and retrospective) that evaluated any endovascular procedure in patients with long FP lesions classified TASC (Trans-Atlantic Inter-Society Consensus document II on management of peripheral arterial disease) C and/or D, and a mean length >150 mm, primary outcome had to be the 1-year primary patency. Overall estimate of primary patency, secondary patency, and freedom from target lesion revascularization (TLR) at 1 year depending on the different devices were investigated. The meta-analysis was conducted following the requirements of the MOOSE (Meta-analysis of Observational Studies in Epidemiology) checklist. RESULTS Forty-four papers comprising 4847 patients and 5282 treated limbs were included. Mean lesions length ranged from 150.5 to 330 mm. The pooled 1-year primary and secondary patencies, and freedom from TLR rates were 0.71 (95% CI: 0.67-0.74), 0.87 (95% CI: 0.83-0.91), and 0.79 (95% CI: 0.74-0.84), respectively. Primary permeability at 1 year were 0.68 (95% CI: 0.62-0.73), 0.67 (95% CI: 0.60-0.74), 0.74 (95% CI: 0.64-0.84), and 0.83 (95% CI: 0.78-0.88) for bare metal stents, covered stents (CSs), drug-eluting stents, and drug-coated balloons (DCBs), respectively. Lesions treated with DCB had the highest 1-year primary patency rate. CONCLUSIONS At 1-year, endovascular procedures for FP lesions greater than 150 mm obtain satisfactory results. High primary patency rates were obtained with drug-coated devices, while CSs obtained less favorable results. Randomized studies comparing different devices in the treatment of long FP lesions remain necessary to determine the most optimal approach for the management of these patients. CLINICAL IMPACT This paper highlights on the one hand the satisfactory results of endovascular treatment on complex femoropopliteal lesions formerly reserved for conventional surgery. On the other hand, among the available devices, paclitaxel-eluting devices seem to show superior results which should make them recommended as first-line treatment.

Algorithm of Femoropopliteal Endovascular Treatment. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58091293. [PMID: 36143968 PMCID: PMC9501396 DOI: 10.3390/medicina58091293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Revised: 09/06/2022] [Accepted: 09/12/2022] [Indexed: 12/04/2022]
Abstract
Background and Objectives: Indications for the endovascular treatment of femoropopliteal lesions have steadily increased over the past decade. Accordingly, the number of devices has also increased, but the choice of the best endovascular treatment remains to be defined. Many devices are now available for physicians. However, in order to obtain a high success rate, it is necessary to respect an algorithm whose choice of device is only one step in the treatment. Materials and Methods: The first step is, therefore, to define the approach according to the lesion to be treated. Anterograde approaches (femoral, radial, or humeral) are distinguished from retrograde approaches depending on the patient’s anatomy and surgical history. Secondarily, the lesion will be crossed intraluminally or subintimally using a catheter or an angioplasty balloon. The third step corresponds to the preparation of the artery, which is essential before the implantation of the device. It has a crucial role in reducing the rate of restenosis. Several tools are available and are chosen according to the lesion requiring treatment (stenosis, occlusion). Among them, we find the angioplasty balloon, the atherectomy probes, or intravascular lithotripsy. Finally, the last step corresponds to the choice of the device to be implanted. This is also based on the nature of the lesion, which is considered short, up to 15 cm and complex beyond that. The choice of device will be between bare stents, covered stents, drug-coated balloons, and drug-eluting stents. Currently, drug-eluting stents appear to be the treatment of choice for short lesions, and active devices seem to be the preferred treatment for more complex lesions, although there is a lack of data. Results: In case of failure to cross the lesion, the retrograde approach is a safe and effective alternative. Balloon angioplasty currently remains the reference method for the preparation of the artery, the aim of which is to ensure the intraoperative technical success of the treatment (residual stenosis < 30%), to limit the risk of dissection and, finally, to limit the occurrence of restenosis. Concerning the treatment, the drug-eluting devices seem to present the best results, whether for simple or complex lesions. Conclusions: Endovascular treatment for femoropopliteal lesions needs to be considered upstream of the intervention in order to anticipate the treatment and the choice of devices for each stage.

Abstract
BACKGROUND Endovascular balloon angioplasty is a common practice to treat femoropopliteal arterial lesions. The precise balloon inflation duration to obtain the best lesion dilatation is unclear. The aim of this study was to assess angiographic images after 3- and 5-minute balloon inflation in femoropopliteal de-novo atherosclerotic lesions. METHODS We randomly assigned 61 femoropopliteal arterial lesions to undergo balloon angioplasty for 3 and 5 minutes. The primary endpoint was the rate of favorable angiographic images after balloon angioplasty. The correlation between angiographic image and degree of calcification was studied. The secondary endpoint was the need of additional ballooning or stenting of the dilated lesion. RESULTS Thirty-two (52%) lesions were randomized to a 3-minute inflation time and 29 (48%) lesions to a 5-minute inflation time. Median lesion length was 83±32mm in the 3-minute group and 89±31mm in the 5-minute inflation group (P=0.47). After deflation, vessel recoil was significantly higher in the 3-minute group compared to the 5-minute group (P=0.04), in mild to moderate calcified lesions, 18 (56%) and 9 (31%) cases, respectively. The angiographic result after balloon angioplasty was significantly more favorable (P=0.007) in the 5-minute group with 20 (69%) cases compared to 10 (31%) cases in the 3-minute group. An increase of vessel recoil of 62% has been seen in severe calcified lesions in the 5-minute group. Additional intervention rate was significantly higher (P=0.007) in the 3-minute group compared to the 5-minute group. CONCLUSIONS A prolonged inflation time of 5 minutes has an overall better angiographic image in the femoropopliteal segment and especially in non- or mildly calcified lesions.

Abstract
A method to manage ST-segment elevated myocardial infarction (STEMI) caused by very late stent thrombosis (VLST) has yet to be established. In this case series, we present several cases of STEMI caused by VLST, which were successfully revascularized using a perfusion balloon. Since the perfusion balloon (Ryusei: Kaneka Medix Corporation, Osaka, Japan) has the unique advantage of maintaining blood flow during balloon inflation, we can keep dilating the target lesion for more than several minutes. Extended inflation might work to prevent acute recoil, and to achieve optimal expansion without an additional stent. Our case series may provide a reasonable option for the treatment of VLST.

Abstract
Symptomatic peripheral arterial disease management involves medical treatment and interventional procedures. Intermittent claudication and critical limb threatened ischemia (CLTI) should be individually considered with specific outcomes and procedures. When intervention is required, an endovascular approach is usually the first-line option. Plain balloon angioplasty was previously used to dilate clinically significant femoropopliteal lesions with variable results. However, over recent years, the use of self-expanding nitinol stents has enabled treatment of long lesions, yielding significantly improved clinical results. Drug-eluting technology has also exhibited a capacity to limit in-stent restenosis and to drive target revascularization. Nevertheless, calcifications and elastic recoil of the arterial wall remain risk factors for early restenosis and failure. Therefore, vessel preparation using specific devices is required to modify vessel compliance and debulk obstructive calcification. In this short review, we provide an overview of the options for gaining lumen before stenting or dilation using drug-coated balloons.

Abstract
PURPOSE The knowledge regarding the benefits of the scoring balloon (SB) in comparison to the plain balloon (PB) is limited. This study aims to elucidate the difference in efficacy between SB and PB as pre-balloon in superficial femoral artery angioplasty. METHODS We retrospectively analyzed angiographic images of 113 lesions in 98 patients treated with endovascular surgery. 37 lesions were prepared by SB and 76 lesions by PB. Lesions without significant residual stenosis nor a flow-limiting dissection were treated by drug-coated balloon and the others by drug-eluting stent. Severity of dissection was evaluated by Kobayashi dissection grade and NHLBI classification. The rate of stent implantation was compared between the 2 groups. Kaplan-Meier analysis estimated freedom from target lesion revascularization (TLR) rate at 12 months. RESULTS Severe dissections (>1/3 of lumen) occurred less frequently in the SB group (SB 40.5% vs. PB 75.0%, P = 0.001). Overall stent implantation rate was lower in the SB group (SB 27.0% vs. PB 55.3%, P = 0.005). In subgroup analysis for the complex lesions, the SB group had lower rate of severe dissection(>1/3 of lumen) in patients with long lesions(>15 cm) (SB 51.7% vs. PB 76.9%, P = 0.020) and lesions of calcium grade ≥2 (SB 43.8% vs. PB 72.5%, P = 0.009). SB group had lower stent implantation rate in patients with long lesions (SB 34.5% vs. PB 59.6%, P = 0.030), lesions of calcium grade ≥2 (SB 31.3% vs. PB 56.9%, P = 0.023), and total occlusion (SB 30.8% vs. PB 80.0%, P = 0.002). There were no procedure-related complications in either group except 1 case of puncture-site hematoma. There was no significant difference in TLR rate between both groups at 12 months (P = 0.509). CONCLUSION SB reduces the incidence of severe dissection (>1/3 of lumen) and rate of overall stent implantation in comparison with PB. The use of SB is a safe and effective method of lesion preparation in SFA angioplasty.

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
Purpose: To evaluate a new scoring balloon, the non-slip element (NSE) percutaneous transluminal angioplasty (PTA) balloon, in the treatment of femoropopliteal lesions by comparing angiographic dissection patterns to those of a conventional balloon. Methods: This retrospective, single-center study included 71 symptomatic patients (mean age 77.4±8.8 years; 33 men) with de novo femoropopliteal lesions <20 cm long treated with balloon angioplasty between January 2017 and May 2018. Thirty-four patients were treated with 3 inflations of an NSE balloon and 37 patients were treated with a conventional balloon. Results: Severe dissections were fewer (8.8% vs 29.7%, p=0.027) and the total dissection length was shorter (11.5±12.8 vs 35.7±24.1 mm, p=0.027) in the NSE group. The bailout stenting rate was also lower in the NSE group (17.6% vs 40.5%, p=0.035). There were no significant differences between the groups regarding lesion length (70.3±50.4 vs 77.8±56.6 mm, p=0.28), inflation time (294±162 vs 353±179 seconds, p=0.08), or inflation pressure (10.6±5.0 vs 11.3±5.3 atm, p=0.31). Conclusion: Three NSE balloon inflations may reduce severe dissections induced by balloon angioplasty in femoropopliteal lesions.

Purpose: To explore the provisional use of a drug-eluting stent (DES) after suboptimal drug-coated balloon (DCB) angioplasty in complex, calcified femoropopliteal lesions. Materials and Methods: A prospective, single-center, investigator-initiated pilot study enrolled 15 patients (mean age 71.3 years; 9 men) with symptomatic stenosis (n=6) or occlusion (n=9) of the native superficial femoral and/or proximal popliteal arteries who experienced suboptimal DCB dilation despite postdilation. Lesion characteristics were evaluated with computed tomography angiography and duplex ultrasound confirmed by intravascular ultrasound. Follow-up included clinical and imaging evaluations as well as blood tests to monitor inflammatory markers. Endpoints included systemic inflammation, acute/chronic thrombosis, aneurysm formation, and mortality. Results: Provisional stenting was required for residual stenosis >50% in 4 cases and flow-limiting dissection in 11. Provisional spot stenting was done using the Zilver PTX DES. Clinical improvement was observed in all cases. After 24-month follow-up all patients were alive and in good clinical condition. One- and 2-year primary patency rates were 93.3% and 92.9%, respectively; secondary patency was 100%. Restenosis required reintervention in 2 cases. No local or systemic complications or toxicity were observed due to the use of a double dose of paclitaxel. No significant increase in any inflammation marker was observed in the perioperative period, and no aneurysm formation was seen over 24 months of follow-up. Conclusion: Combined DCB plus DES therapy seems to be safe and correlated with high primary patency following suboptimal angioplasty. Larger studies are required to confirm the safety and efficacy of this approach.

Prolonged versus brief balloon inflation during arterial angioplasty for de novo atherosclerotic disease: a systematic review and meta-analysis. CVIR Endovasc 2019; 2:29.

Abstract
OBJECTIVE Angioplasty is a fundamental treatment for atherosclerotic disease and may be performed as the sole therapy in small vessel disease. However, the ideal duration of balloon inflation has not yet been identified. Our study investigated whether prolonged inflation of at least 1-min duration, when compared with brief inflation, affects residual stenosis after arterial angioplasty. DATA SOURCES AND METHODS Two independent reviewers conducted a systematic review of EMBASE, MEDLINE, CENTRAL, trial registries and grey literature, using pre-specified search syntax. Data abstraction and quantitative analysis was performed independently, according to pre-specified criteria. The primary outcome was residual stenosis after initial angioplasty, in addition to other pre-specific clinical and radiographic outcomes. All analyses were stratified by coronary, cerebrovascular, and peripheral territory. The study protocol is published and registered on PROSPERO (CRD42018092702). RESULTS Six relevant articles were identified, of which one investigated peripheral vascular angioplasty and five investigated coronary artery angioplasty, encompassing 1496 procedures. The studies were at moderate risk of bias. Minimal heterogeneity within coronary studies allowed for subgroup meta-analysis. Prolonged inflation was significantly associated with lower risk of residual stenosis post-inflation in the pooled coronary trials (RR 1.76 [95% CI 1.46-2.12], I2 = 0%, p < 0.001) in addition to approaching significance in the peripheral vascular trial (RR 2.40 [95% CI 0.94-6.13], p = 0.07). Prolonged inflation was associated with less risk of arterial dissection and need for adjunctive procedures such as stenting. Following adjunctive procedures, less residual stenosis was still observed in the prolonged angioplasty group in the reported coronary studies. Follow-up data did not reveal a significant difference in the presence of restenosis, however there was a long-term benefit of prolonged inflation in reducing overall severity of stenosis. DISCUSSION This is the first review investigating outcomes related to duration of balloon inflation. Both coronary and peripheral vascular evidence are in agreement that prolonged angioplasty balloon inflation greater than 60 s appears to be associated with improved immediate post-inflation results. However, long-term data is heterogeneous and inconsistently reported. We propose further investigation to address outstanding long-term outcomes, particularly in small vessel territories such as tibial vessels where angioplasty is often used as the only endovascular therapy. TRIAL REGISTRATION This protocol has been registered with the International Prospective Register of Systematic Reviews (PROSPERO: CRD42018092702 ) prior to conduct of the review.

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
Purpose: To systematically review the literature and extract information on the definitions, prevalence, implications, and treatment of dissections after infrainguinal balloon angioplasty, with a goal of summarizing current data and identifying gaps in knowledge to help direct future research. Materials and Methods: A systematic review was performed according to the PRISMA guidelines. Medline (PubMed), Scopus, and Cochrane CENTRAL databases were reviewed for prospective and retrospective studies reporting dissection identification, characterization, incidence, severity, and/or outcomes after infrainguinal balloon angioplasty up to January 30, 2019. The electronic search resulted in 288 studies. From these, 153 full-text articles were assessed, and 51 published from 1964 to 2018 were selected as relevant to this systematic review. Because of the significant between-study differences in lesion characteristics, reporting methods, and lack of core laboratory adjudication, the findings were summarized from each study, but the results were not pooled. Results: The mechanism of percutaneous transluminal angioplasty (PTA) consists of adventitial stretching, medial necrosis, and controlled dissection or plaque fracture. PTA-induced dissections can precipitate pathological high and low shear hemodynamic defects and have been implicated as a contributing factor in procedural complications as well as restenosis at the treatment site. The development of significant dissection after PTA often leads to the use of adjunctive therapies, including stent placement. Despite the ubiquitous nature of dissection after balloon angioplasty (incidence 7.4% to 84%), limited data are available to categorize dissections in the peripheral arteries and direct subsequent treatments to improve vessel patency. With the increased utilization of drug-coated balloon angioplasty, understanding the outcomes of postangioplasty dissection has become increasingly important, as the decision to treat dissections with additional strategies has therapeutic and economic implications. Conclusion: All post-PTA dissections in the femoropopliteal arteries may benefit from a treatment approach that ensures optimal hemodynamics with long-term durability in treated lesions. Further understanding the importance of postangioplasty dissections, along with the development of new technologies, will help optimize the patency of endovascular interventions.

Abstract
Purpose: To report outcomes of a multicenter feasibility study using the FLEX Vessel Prep (VP) System, a novel technology that facilitates plaque incision and lumen gain in stenosed or occluded femoropopliteal arteries prior to balloon angioplasty. Materials and Methods: Two hundred fifty-five patients (mean age 71.8±9.1 years) were treated with the FLEX VP System at 38 centers between December 2015 and November 2017. Average lesion length was 133±88 mm. Average baseline stenosis was 92%±11%; 112 (44.3%) of 253 patients presented with a chronic total occlusion. Conventional or drug-coated balloon (DCB) angioplasty was performed in all patients after vessel preparation. Vessel measurements were derived from angiograms acquired at baseline, after FLEX passage, and after subsequent ancillary procedures. Logistic regression analyses were performed to identify baseline or procedure variables that predicted the need for provisional stenting. Results: Average percent reduction in vessel stenosis following treatment with the FLEX VP System was 27%±17%. No flow-limiting dissection, vessel perforation, or embolization was observed; 15 (5.9%) patients had minor (type A or B) dissections. Provisional stenting was performed in 49 (19.2%) patients. Average stenosis following angioplasty ± stenting was 9.1%±7.4%; 9 (3.6%) patients had significant residual stenosis ≥30%. Logistic regression analyses found that patients with dissections, longer lesions, and those receiving conventional balloon dilation alone were most likely to undergo stenting. Conclusion: In a real-world patient population with long, complex femoropopliteal lesions, use of the FLEX VP System as vessel preparation for angioplasty improved acute outcomes compared to historical controls. The rate of provisional stenting was low, and no serious vessel complications were observed.

Abstract
BACKGROUND Angioplasty is a fundamental treatment for atherosclerotic disease in the cardiac, cerebrovascular, and peripheral vascular beds. However, the optimal duration of balloon inflation has not been identified. Our study will investigate whether prolonged angioplasty balloon inflation of at least 1 min duration, when compared with brief inflation, affects residual stenosis after arterial angioplasty. METHODS In compliance with PRISMA, two independent reviewers will conduct a systematic review of EMBASE, MEDLINE, CENTRAL, trial registries, grey literature, and ancestry and citation search. Data abstraction, quantitative, and quantitative meta-analysis will be performed according to pre-specified criteria. The primary outcome is residual stenosis immediately after initial angioplasty; however, secondary outcomes will include multiple short and long term pre-specific clinical and radiographic outcomes. Risk of bias, subgroup analyses, and sensitivity analyses are planned. DISCUSSION Despite the ubiquitous use of angioplasty in atherosclerotic disease and multiple trials investigating the ideal balloon inflation duration, there are no systematic reviews evaluating prolonged angioplasty balloon inflation. Currently synthesized evidence is insufficient to confidently direct clinical decision-making, and the current variation in operator preference of balloon angioplasty duration suggests ongoing clinical equipoise. Given the known availability of current primary evidence, our study intends to synthesize the evidence and guide future clinical decision making and investigation.

Abstract
INTRODUCTION Hemodialysis patients with an arteriovenous fistula can use buttonhole techniques for cannulation. Although buttonholes generally work well, patients may report difficult and painful cannulation, and buttonholes may fail over time. We aimed to assess the effectiveness of tract dilation in treatment of failing buttonholes. METHODS We retrospectively analyzed data from patients treated with buttonhole tract dilation at an outpatient vascular access center between January 2013 and August 2015. RESULTS Data from 23 patients were analyzed. There were 51 tract dilation procedures during 36 encounters for failing arteriovenous fistula buttonhole tract(s). The technical success rate for established tract dilation with "blunt-recanalization" was 90% (n = 46). The five remaining buttonholes had "sharp-recanalization" to create and dilate new tract through the buttonhole. For 46 buttonholes treated with "blunt-recanalization," there was an 85% clinical success rate at one week (39 buttonholes), and one was lost to follow-up; there was a 70% clinical success rate after one month (32 buttonholes). In the five buttonholes with "sharp-recanalization," there was only one clinical success with p < 0.05 for difference in success rate compared to "blunt-recanalization" at both one week and one month. There was one complication from "sharp-recanalization" requiring abandonment of the buttonhole tract. DISCUSSION Buttonhole tract dilation is a useful method to treat difficult cannulation and painful cannulation and has the potential to extend the life of failing buttonholes.

Abstract
Purpose: To investigate if balloon angioplasty with a prolonged inflation time (>3 minutes) can prevent postdilation dissection in femoropopliteal lesions. Methods: A retrospective single-center analysis examined 294 consecutive patients (mean age 74.1±8.7 years; 215 men) with de novo femoropopliteal lesions treated with balloon angioplasty between 2013 and 2018. The patients were classified into 2 groups to compare angiographic dissection patterns: 175 patients treated with balloon angioplasty for 3 minutes (3-minute group) and 119 treated for >3 minutes (>3-minute group). Results: Mean balloon inflation time was 7.8±2.7 minutes in the >3-minute group. Severe dissections (type C or higher) were observed less frequently after balloon dilation in the >3-minute group (22.7% vs 50.9%, p<0.001); therefore, significantly more patients in the >3-minute group had successful endovascular treatment after initial balloon angioplasty (57.1% vs 38.3%, p=0.001). Additional balloon dilation was attempted more frequently in the 3-minute group (30.9% vs 14.3%, p=0.001); as a result, there were more patients in whom additional balloon dilation repaired severe dissection that occurred after the initial dilation (25.1% vs 10.9%, p=0.001). Multivariate analysis revealed that chronic total occlusion (p<0.001) and longer lesion (p<0.001) were independent predictors of severe dissection, and prolonged dilation time was independently related to preventing severe dissection (p<0.001). Among 171 patients undergoing successful balloon angioplasty without stent implantation, the Kaplan-Meier estimates of primary patency within 1 year did not differ significantly according to inflation time. Conclusion: Balloon dilation with prolonged inflation time (>3 minutes) may be effective as an initial strategy to prevent severe dissection in femoropopliteal lesions compared to inflation for 3 minutes.

A Single-Center Retrospective Analysis of the Efficacy of a New Balloon Catheter in Autogenous Arteriovenous Fistula Dysfunction Resistant to Conventional Balloon Angioplasty. Ann Vasc Surg 2017; 48:79-88.

Abstract
PURPOSE The purpose of the study was to present a new alternative balloon catheter option for autogenous arteriovenous fistula (AVF) dysfunction with a stiff constriction resistant to conventional balloon angioplasty. METHODS Our first series of 51 patients with autogenous AVF dysfunction who were simultaneously treated with VascuTrak™ balloon catheter, following failed conventional balloon therapy (failure was defined as residual stenosis of >30%), were retrospectively observed and analyzed. The indices that were used to evaluate the clinical efficacy of VascuTrak balloon catheter included the immediate technical success rate, residual stenosis, successful dilation times, degree of pain assessed using the Visual Analog Scale, complications, and follow-up patency rate. RESULTS The stenotic or occlusive lesions of all 51 cases resistant to conventional balloon angioplasty were promptly eliminated or alleviated (residual stenosis rate ≤ 30%), with a 100% immediate technical success rate. VascuTrak balloon catheters were successful in achieving full dilation under working pressure, of which 44 cases required a 1-time dilation (86.3%) and 7 cases required 2 dilations, which differed significantly from the average of 2.4 dilations required by the preceding conventional balloon therapy (P < 0.0001). A statistically significant improvement in the degree of pain experienced by patients who received VascuTrak balloon dilation was observed compared to that of the preceding conventional balloon dilation (P < 0.0001). One case of a brachial artery pseudoaneurysm complication occurred in the perioperative period. The primary patency rate was 88.2% at 6 months and 74.5% at 12 months. CONCLUSION The use of VascuTrak balloon catheter to treat autogenous AVF dysfunction resistant to conventional balloon angioplasty appears to be safe and effective, although further, large randomized controlled trials are necessary.

Abstract
The endovascular treatment of atherosclerotic disease of the infra-inguinal arteries has changed significantly over the last decades. In an attempt to overcome the high restenosis rates that characterize plain balloon angioplasty and stenting using bare mate stents drug-eluting balloon technology has been applied in the treatment of lesions of the superficial femoral and popliteal artery. This paper will give an overview of the rationale and the technology of drug-eluting balloons and will review currently available data from registries and randomized controlled trials.

Abstract
Local drug delivery of an anti-proliferative drug from balloon catheter systems to the site of arterial injury has been attempted repeatedly over the years with limited success in drug uptake and retention. Accessibility of the drug at the site is critical to combat the body's response to the procedural trauma of angioplasty. Recently, formulations have been designed which achieve delivery of therapeutic doses of the anti-proliferative drug paclitaxel to arteries with higher efficiency and longer tissue retention. These formulations succeed through formation of a drug reservoir in the artery wall enabling release after the initial angioplasty procedure. These formulations have become the cornerstone of several drug coated balloon (DCB) technologies which have found an initial, broad therapeutic application in the treatment of stenosis of the superficial femoral artery (SFA). DCBs achieve drug delivery while leaving no implant behind and represent a new class of combination products developed at the interface of engineering, chemistry and medical science. This review article summarizes the development of the LUTONIX® drug coated balloon catheter. The introduction of DCB technology has provided clinicians and patients with new SFA treatment options while ongoing clinical evidence in additional vascular beds is generated.

Abstract
Purpose: To report the findings from a multicenter study of patients treated with cryoplasty who were then followed for an average of >2 years post-treatment. Methods: Extended clinical follow-up was obtained for 70 patients (45 men; mean age 70.5±8.8 years) who originally received cryoplasty therapy to treat symptoms of intermittent claudication as part of a multicenter investigational device exemption (IDE) study. For all subjects, cryoplasty was used to treat stenoses or occlusions ≤10 cm in the femoropopliteal arteries. The original IDE study protocol enrolled 102 patients with a primary endpoint of target lesion patency at 9 months post-treatment. This collection of additional longer term follow-up data was initiated 2.5 years after the onset of study enrollment. Results: Extended clinical follow-up ranged from 11 to 41 months (mean 31). The clinical patency rate (freedom from target lesion revascularization) calculated by the Kaplan-Meier method was 83.2% after the original follow-up period of 300 days. After >3 years (1253 days), the clinical patency rate was well maintained at 75.0%. Conclusions: Long-term data indicate that cryoplasty is a durable therapy, with relatively low long-term restenosis rates compared to other endovascular treatment approaches.

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
PURPOSE To examine the 2-year mortality in hemodialysis (HD) patients with critical limb ischemia (CLI) and determine predictors that may aid in the selection of a revascularization strategy [bypass surgery or endovascular therapy (EVT)] according to current guidelines. METHODS From 2007 to 2009, 246 consecutive CLI patients (mean age 69±10 years; 170 men) on HD underwent revascularization for de novo infrainguinal lesions (178 EVT and 68 bypass grafting). The majority of the patients had diabetes (170, 69%) and tissue loss (194, 79%); nearly half (111, 45%) were nonambulatory. Overall survival after revascularization was estimated by Kaplan-Meier analysis. Predictors for 2-year mortality after revascularization were determined using a Cox proportional hazards model; results are given as the hazard ratio (HR) and 95% confidence interval (CI). RESULTS Overall survival rate was 77% at 1 year and 66% at 2 years. Predictors of 2-year mortality after revascularization were age >75 years (HR 1.82, 95% CI 1.14 to 2.91, p=0.012), albumin <3 g/dL (HR 2.31, 95% CI 1.39 to 3.84, p=0.001), and ejection fraction <50% (HR 1.73, 95% CI 1.06 to 2.83, p=0.027). Patients with more predictors had a higher incidence of death within 2 years after revascularization. CONCLUSION Advanced age, low albumin level, and low ejection fraction were independently associated with 2-year mortality after revascularization in HD patients with CLI. Risk stratification by these factors would be useful for deciding on a revascularization strategy.

Abstract
To date, no ideal endovascular strategy has been established for traumatic arterial occlusion. Here, we report the outcomes of a combination of endovascular recanalization techniques applied in two patients with high risk of leg amputation. A 33-year-old man with popliteal artery occlusion due to blunt trauma was treated by balloon angioplasty with long inflation time and aspiration thrombectomy. A 74-year-old woman with popliteal artery occlusion after total knee replacement was treated by aspiration thrombectomy and stent placement. In both cases, we achieved satisfactory recanalization, and peripheral ischemia was absent even 1 year later.

Abstract
Predictors of provisional stenting in patients undergoing lower extremity arterial interventions remain unclear. We performed an ad hoc analysis on the predictors of provisional stenting during infrainguinal arterial percutaneous interventions using data from the Percutaneous Lower Extremity Arterial Interventions Using Primary Balloon Angioplasty versus Silverhawk Atherectomy (SA) and Adjunctive Balloon Angioplasty trial. In the above trial, SA of infrainguinal de novo arterial lesions was shown to reduce significantly provisional stenting compared with primary percutaneous transluminal angioplasty (PTA). In this ad hoc analysis, patients were divided into two groups based on whether provisional stenting has occurred. Univariate analysis was conducted between the stent versus the no-stent group. Logistic regression (LR) analysis was performed to model for the predictors of provisional stenting. Variables included were diabetes, presence of moderate calcification (versus none to little), age, gender, hypercholesterolemia, Transatlantic Intersociety Consensus (TASC) D lesion (vs. TASC A to C), and treatment method (primary PTA vs. SA with adjunctive PTA). By LR analysis, predictors of stenting were as follows: moderate calcification (odds ratio [OR] 6.56, 95% confidence interval [CI] 1.21 to 35.56, p = 0.029), primary PTA (vs. SA) (OR 0.19, 95% CI 0.04 to 0.93, p = 0.04), and TASC D lesions (vs. A to C) (OR 0.10, 95% CI 0.01 to 0.87, p = 0.037). Provisional stenting in infrainguinal interventions is predicted by the use of primary PTA, presence of moderate calcification, and TASC D lesions after controlling for gender, age, hypercholesterolemia, and diabetes.

Abstract
PURPOSE Target lesion revascularization (TLR) with primary percutaneous transluminal angioplasty (PTA) versus SilverHawk atherectomy and adjunctive PTA of de novo infrainguinal disease has not been well defined. This study was conducted to compare the two approaches. MATERIALS AND METHODS In this prospective, two-center randomized trial of PTA versus atherectomy of infrainguinal vessels, the primary endpoint of TLR was evaluated at 1 year. Secondary endpoints included the rate of "bailout" stent placement for suboptimal acute angiographic results and the rate of target vessel revascularization (TVR). RESULTS Fifty-eight patients were included in the study. Of these, 29 (36 vessels) were randomized to the atherectomy arm and 29 (48 vessels) to the PTA arm. Final acute angiographic success rates were 100% in the PTA arm and 97.2% in the atherectomy arm (P value not significant). There was no statistical difference in TLR (16.7% vs 11.1%) or TVR (21.4% vs 11.1%) between the PTA and atherectomy groups, respectively. Bailout stent placement was performed in 18 of 29 patients (62.1%) in the PTA arm and eight of 29 patients (27.6%) in the atherectomy arm (P = .017). Major adverse events were similar between the PTA and atherectomy arms. Finally, when embolic filter protection was used, distal macroembolization occurred in 11 of 17 patients (64.7%) treated with atherectomy versus none of 10 in the PTA group (P < .001). CONCLUSIONS TLR and TVR at 1 year were statistically similar in atherectomy and primary PTA. Atherectomy reduced the need for bailout stent placement compared with primary PTA.

Abstract
PURPOSE Symptomatic atherosclerotic disease of the popliteal artery presents challenges for endovascular therapy. We evaluated the technical success, complications, and midterm outcomes of atherectomy and angioplasty involving the popliteal segment. METHODS We conducted a retrospective review of outcomes of popliteal artery intervention using atherectomy or angioplasty performed between 2003 and 2008. RESULTS A total of 56 patients (36% women, age 72.8 +/- 12.2 years, 77% critical limb ischemia) underwent popliteal atherectomy (n = 18) or angioplasty (n = 38). These patients had similar clinical characteristics, TransAtlantic Intersociety Consensus (TASC)/ TASC II classification, mean lesion length, and runoff scores. We observed a trend toward higher rates of technical success defined as <30% residual stenosis after atherectomy compared to angioplasty (94% vs 71%, P = .08). While angioplasty was associated with a higher frequency of arterial dissection (23% vs 0%, P = .003), atherectomy was associated with a higher rate of thromboembolic events (22% vs 0%, P = 0.01). Adjunctive stenting was used more frequently following angioplasty compared to atherectomy (45% vs 6%, P = .005). Thrombolysis was used to treat embolization in 4 patients in the atherectomy group. The improvement in the ankle-brachial index (ABI) was similar between the 2 treatment groups. Primary patency of the popliteal artery at 3, 6, and 12 months was 94%, 88%, and 75% in the atherectomy group and 89%, 82%, and 73% in the angioplasty group (P = not significant [NS]). There were no significant differences in limb salvage and freedom from reintervention at 1 year between the atherectomy and angioplasty groups. CONCLUSIONS Our experience with popliteal artery endovascular therapy indicates a distinct pattern of procedural complications with atherectomy compared to angioplasty but similar midterm patency, limb salvage, and freedom from intervention.

Abstract
Objective: We analyzed our results with percutaneous rotational atherectomy catheters and specifically examined whether they were more likely to be associated with a successful outcome when used to treat smaller diameter vessels such as infrapopliteal (IP) arteries compared to larger diameter femoropopliteal (FP) arteries and infrainguinal arterial autogenous vein grafts (GRAFTS). Material and Methods: Between January 1, 2005, and December 31, 2006, athrectomies were performed on 32 patients for claudication (14), gangrene (9), rest pain (4), and failing GRAFTS (5). Treated vessels included 14 superficial femoral, 1 popliteal, 5 anterior tibial, 4 posterior tibial, and 3 peroneal arteries along with 5 failing GRAFTS. All procedures were performed by vascular surgeons in an endovascular operating suite using a mobile C-arm. Results for larger diameter vessels including FP arteries and GRAFTS were combined (FP + BYPASSES) and compared to results of IP artery lesions. Follow-up averaged 10 weeks (range, 0.5-34 weeks). Results: Length of treated lesions averaged 4.2 cm (range, 1—15 cm) for FP + GRAFT lesions (9 occlusions, 11 stenoses) versus 1.8 cm (1-4 cm) for IP lesions (6 occlusions, 6 stenoses; P = ns). Procedural success rate based on postoperative segmental pressures, pulse volume recordings, and duplex ultrasound was 70% (14/20) for FP + GRAFTS versus 83% (10/12) for IP lesions (P = .03). Need for concomitant adjunctive balloon angioplasty to treat residual stenosis tended to be higher for FP + GRAFT lesions (40% [8/20]) compared to IP lesions (25% [3/12]; P = ns). During follow-up, 25% (5/20) of FP + GRAFTS lesions required reintervention (3 balloon angioplasties, 1 thrombectomy, 1 GRAFT pseudoaneurysm) versus none for the IP lesions (P = .03). Limb salvage rates were 90% (18/20) for FP + GRAFT lesions versus 100% (12/12) for IP lesions during this short follow-up. Conclusions: These preliminary results suggest that short segment IP arterial stenoses and occlusions can be successfully treated with atherectomy catheters with a lower rate of reintervention during short-term follow-up, less need for concomitant adjunctive balloon angioplasty and a lower complication rate compared to FP + graft lesions.

Abstract
OBJECTIVE We have observed that some patients with isolated popliteal artery occlusions (PAOs) harbor varying degrees of organized clot, as suggested by the rapidity with which these occlusions are traversed with the Glidewire. We hypothesized that debulking such PAOs by using rheolytic thrombectomy without adjunctive thrombolysis before percutaneous transluminal angioplasty and selective stenting (PTA/S) is safe and enables single-session treatment with minimal risk of embolization. METHODS Between February 2004 and January 2007, 16 male patients (mean age, 68.9 +/- 11.1 years; range, 54-84 years) presenting with disabling claudication (n = 1), rest pain (n = 5), and tissue loss (n = 10; mean duration, 11 +/- 8 weeks; range, 4-26 weeks) were prospectively followed up after rheolytic thrombectomy and angioplasty and selective stenting of their PAO. RESULTS The mean occlusion length was 11.6 +/- 4.5 cm. After rheolytic thrombectomy, the occlusions were converted to long stenoses (mean length of 7.6 +/- 3.6 cm). Self-expanding stents were used in 10 of 16 (mean length of 8.3 +/- 4.4 cm). Additional recanalizations of occlusions of the iliac artery and proximal superficial femoral artery were performed before popliteal artery recanalizations in two patients. Ankle-brachial indexes increased from 0.27 +/- 0.22 to 0.94 +/- 0.13. No case of distal embolization was observed. Adjuvant thrombolysis was used in only one case to improve runoff. Inline flow to the foot was achieved in 15 of 16 cases. Three occlusions occurred at 3, 6, and 20 months after surgery (mean follow-up, 15.7 +/- 10.0 months), and two patients underwent successful thrombolysis. The third patient refused further intervention and remains a claudicant. One-year primary and secondary patency rates were 84% and 92%, respectively. Two limb losses occurred at 7 and 9 months as a result of recurrent foot infection in patients with diabetes, both with patent popliteal arteries (1-year limb salvage rate, 83%). CONCLUSIONS We advocate debulking isolated subacute PAOs with rheolytic thrombectomy when they are easily crossed, because this enables recanalization of these lesions in a single setting, thus obviating the additional need for thrombolysis in most cases, with seemingly minimal risk of distal embolization. This simple approach is effective and widely available.

Abstract
PURPOSE To determine midterm clinical outcomes among patients with lower extremity peripheral arterial disease who underwent revascularization with catheter-based plaque excision (PE). METHODS Between August 2003 and February 2005, 19 institutions participating in the observational, nonrandomized, multicenter TALON registry enrolled 601 consecutive patients (353 men; mean age 70+/-11, range 36-98) with 1258 symptomatic lower extremity atherosclerotic lesions (748 limbs) treated by plaque excision with the SilverHawk catheter. Approximately 50% of the patients had diabetes, and nearly one third of the procedures were indicated for Rutherford ischemia category > or =4. Mean lesion lengths above and below the knee, respectively, were 62.5+/-68.5 mm (interquartile range [IQR], 20.0-80.0) and 33.4+/-42.7 mm (IQR 15.0-37.5). The primary endpoints of the study were target lesion revascularization (TLR) at 6 and 12 months. RESULTS The device achieved < or =50% residual diameter stenosis in 94.7% of lesions; procedural success was 97.6%. Nearly half (41.9%) of the procedures involved PE of > or =2 lesions. Nearly three quarters (73.3%) of the lesions did not require adjunctive therapy, and stent placement following PE occurred in only 6.3% of lesions. The 6- and 12-month rates of survival free of TLR were 90% and 80%, respectively. Rates of TLR were similar among patients with diabetes (11%) and without diabetes (9%). In the multivariate analysis, significant predictors of TLR at 6 months were a history of MI or coronary revascularization (HR 5.49, 95% CI 1.87 to 16.10, p=0.0008), multiple (> or =2) lesions (HR 1.37, 95% CI 1.11 to 1.70, p=0.0019), and increasing Rutherford category (HR 1.84, 95% CI 1.28 to 2.65, p=0.0003). Lesion length >50 mm was associated with a 2.9-fold increased risk for TLR (HR 2.88, 95% CI 1.18 to 7.01, p=0.012); lesion length >100 mm was associated with a 3.3-fold increase in TLR (HR 3.32, 95% CI 1.15 to 9.56, p=0.016). CONCLUSION In patients undergoing revascularization for lower extremity atherosclerotic disease, catheter-based PE achieves favorable procedural success and avoids the need for repeat revascularization at midterm follow-up. These findings support PE as a primary endovascular therapy for patients undergoing lower extremity arterial revascularization.

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
PURPOSE To compare through digital morphometry, the intimal thickening of the common ilíac arteries (CIA) in pigs, submitted to angioplasty and angioplasty followed by stent implantation. METHODS Angioplasty was performed in 10 pigs in both CIA, followed by a stent implantation in the left CIA. After four weeks, the aorto-iliac segment was dissected. Histologic slices where divided in three groups: left CIA in the area of the proximal (group 1) and distal (group 2) implantation site of the stent and the region of angioplasty in the right CIA (group 3). The histological slices were digitalized to be analyzed by morphometry with calculation of the luminal, intimal and media layers areas. Descriptive statistics analysis was performed through average and standard deviation of areas on each group, using ANOVA, with LSD Post-Hoc test (p<0.05). RESULTS A significant statistic difference was observed when the median area of intimal layer of the groups 1 and 2 where compared with group 3 and in the media layer area of the groups 1 and 2 when compared with group 3. No difference was observed in luminal areas among the three groups. CONCLUSION Angioplasty followed by stent insertion produces an intimal thickening larger than that observed after simple angioplasty. However, the area of the media layer is smaller in the "angioplasty plus stent" group and there is no significant change in the luminal area among the three groups.

Abstract
OBJECTIVE The objectives of this study were to show the feasibility of intraarterial MR angiography of the infrainguinal arteries and to compare the accuracy of intraarterial MR angiography with selective intraarterial digital subtraction angiography for the detection of stenoses before and after percutaneous balloon angioplasty. SUBJECTS AND METHODS Fifteen patients underwent digital subtraction angiography and intraarterial MR angiography before and after balloon angioplasty. For intraarterial MR angiography, 30 mL of diluted contrast agent (5 mL of gadodiamide diluted in 55 mL of 0.9% saline solution) was injected through a sheath in the superficial femoral artery using a flow rate of 2.5 mL/sec. A 3D gradient-echo sequence was performed. Four independent blinded observers assessed differences in the quantitative measurement of stenoses and localization of lesions between digital subtraction angiography and intraarterial MR angiography. The overall impression of the intraarterial MR angiography images was documented on a 4-point scale (1 = excellent, 4 = poor). Interobserver variability was calculated. RESULTS Intraarterial MR angiography from the upper leg to the trifurcation was feasible in all 30 examinations with a mean overall impression of all segments of 1.3 (SD, 0.68). For the detection of significant stenoses (> or = 50% stenosis), the overall sensitivity and specificity for the femoropopliteal and crural vessels were 92.4% and 91.7% and 91.9% and 87.8%, respectively. For the complete leg, sensitivity and specificity were 92.2% and 88.6%, respectively. Interobserver variability for intraarterial MR angiography of the crural vessels exceeded that of the femoropopliteal arteries. CONCLUSION Intraarterial MR angiography of the infrainguinal arteries is feasible in humans using injections of diluted contrast agent at concentrations as low as 8%. It has a high sensitivity for detecting stenoses and an acceptable interobserver variability.

Abstract
PURPOSE Despite suboptimal results, angioplasty of femoropopliteal arterial lesions has been a mainstay of endovascular therapy for many years. The recent introduction of cryoplasty marks a potential advance in the ability to effectively treat peripheral arterial atherosclerotic stenoses. This article presents the results of a prospective, multicenter trial that evaluated the efficacy of cryoplasty for femoropopliteal disease. MATERIALS AND METHODS One hundred two patients with claudication and lesions of the superficial femoral and popliteal arteries of no greater than 10 cm were studied. All patients were treated with a primary strategy of stand-alone cryoplasty with use of the PolarCath cryoplasty system. The primary endpoints of the study were acute technical success and clinical patency at 9 months. Technical success was defined as the ability to achieve residual angiographic stenosis no greater than 30% and residual stenosis less than 50% by duplex ultrasound (US) imaging. Clinical patency was defined as freedom from target lesion revascularization within 9 months. Primary patency was defined by a duplex US systolic velocity ratio no greater than 2.0. RESULTS A total of 102 patients were enrolled at 16 centers. Of those treated, 31% had diabetes and 31% were active cigarette smokers. The majority of the lesions were confined to the superficial femoral artery (84.3%) and 14.7% presented with total occlusions. The mean vessel diameter treated was 5.5 mm +/- 0.5, the mean stenosis diameter was 87% +/- 10%, and the mean lesion length was 4.7 cm +/- 2.6. The technical success rate was 85.3% with a mean residual stenosis after cryoplasty of 11.2% +/- 11.2% (P < .05 vs baseline). Clinical patency in this group was 82.2%, as only 16 patients required target lesion revascularization during the 9-month surveillance period. Primary patency determined by duplex US was 70.1%. CONCLUSIONS Cryoplasty demonstrated a high degree of acute angiographic success and a low frequency of target lesion revascularization. The patency rate observed compares favorably to that previously documented with conventional angioplasty.

Abstract
OBJECTIVE The aim of this study was to demonstrate the possibility of performing magnetic resonance (MR)-guided interventional therapy for femoral and popliteal artery stenoses with commercially available materials supported by MR real-time imaging and intra-arterial MR angiography. MATERIALS AND METHODS A total of 15 patients suffering from symptomatic arterial occlusive disease of the lower limbs with 19 stenoses were included. Interventional intra-arterial digital subtraction angiography was performed before and after angioplasty on each patient as standard of reference. MR images were acquired on a 1.5-T MR scanner. A fast-low-angle shot (FLASH) 3D sequence was applied for a contrast enhanced MR-angiography (ceMRA). A total of 5 mL of diluted gadodiamide was injected via the arterial access. Maximum intensity projections (MIPs) were used as roadmaps and localizers for the interactive positioning of a continuously running 2D-FLASH sequence with a temporal solution of 2 images/second. The lesion was crossed by a balloon-catheter, which was mounted on a guidewire. The visibility was provided by the radiopaque markers on the balloon and was improved by injection of 1 mL of gadolinium into the balloon. Postinterventional control was performed by intra-arterial MR angiography and catheter angiography. RESULTS Stenoses were localized by intra-arterial MR angiography. The guidewire/balloon combination was visible, and the balloon was placed correctly to cover the entire stenoses. Balloon dilation reduced the degree of stenosis by approximately 57% on average. No complications were observed. CONCLUSION MR-guided balloon dilation of femoral and popliteal artery stenoses supported by real-time MR imaging and intra-arterial MR angiography is feasible with commercially available materials.

Abstract
Infrainguinal angioplasty has less initial and long-term success compared with more proximal sites. These suboptimal initial technical results may be related to the heavy calcific burden in the femoral and popliteal arteries and, subsequently, higher incidence of distal dissection. Cutting balloon angioplasty (CBA) is a newer technique that is thought to limit distal dissection in heavily calcified vessels; although CBA has been evaluated in the coronary circulation, there are few reports of its use in peripheral vessels. This study evaluates our initial experience with CBA for the management of femoropopliteal disease. Eleven patients underwent infrainguinal CBA for symptomatic limb ischemia at a community hospital. Ten procedures (91%) were technically successful, with no distal dissections, iatrogenic vessel perforations, or surgical target vessel revascularizations. In eight patients available for follow-up, the limb salvage rate was 100% and of seven and eight CBA sites (88%) were still widely patent (mean follow-up, 3 months; range, 2-12 months). This preliminary study suggests that CBA is safe and feasible for electively performed femoropopliteal chronic occlusive disease with acceptable success rates on short-term follow-up. Long-term results and comparison with other endovascular modalities require evaluation.
