Abstract
PURPOSE Surgical thromboendarterectomy has been the gold standard treatment for common femoral artery (CFA) disease. However, endovascular therapy (EVT) is conducted in certain patients with CFA lesions because of multiple comorbidities. The interwoven nitinol stent (IWS) has been developed to prevent stent fracture. Thus, this study aimed to evaluate the feasibility of EVT using IWS for CFA lesions in clinical practice. MATERIALS AND METHODS This retrospective multicenter registry analyzed patients who had symptomatic lower-extremity artery disease due to CFA lesions and underwent EVT using IWS between 2019 and 2021. The primary endpoint was restenosis 2 years after EVT. RESULTS This study enrolled a total of 177 patients with 196 CFA lesions. The 2-year estimate of freedom from restenosis was 88.0%. The 2-year freedom rates from the target-lesion revascularization, major amputation, and all-cause death were 92.9%, 99.0%, and 75.2%, respectively. The clinical features significantly associated with restenosis risk were the reference vessel diameter (RVD, per 1.0 mm, hazard ratio [HR], 0.24 [0.08-0.70]; p=0.009), external iliac artery (EIA) involvement (HR=4.03 [1.56-10.4]; p=0.004), superficial femoral artery (SFA) involvement (HR=3.05 [1.00-9.25]; p=0.049), body mass index (BMI; per 1.0, HR=0.85 [0.73-0.99]; p=0.032), occlusion of deep femoral arteries (DFAs) at baseline (HR=7.89 [2.04-30.5]; p=0.003), and chronic limb-threatening ischemia (CLTI, HR=2.63 [1.02-6.78]; p=0.045). Their significant association was also confirmed by the random survival forest analysis. During a median follow-up of 12.0 months, guiding sheaths were inserted via CFAs implanted IWSs in 73 cases (37.2%), and no patients had cannulation-related complications, such as failed hemostasis, fracture of IWS, and stent occlusion. CONCLUSIONS Endovascular therapy using IWS in CFA lesions showed acceptable 2-year patency rates at 88.0% and might preserve the arterial access via the ipsilateral CFAs. Small RVD, involving EIA and SFA lesions, emaciation, occluded DFA, and CLTI are associated with poor 2-year patency rates following EVT, thus, IWS implantation in CFA lesions may be an option for patients unsuitable for surgical revascularization. CLINICAL IMPACT This retrospective multicenter registry enrolled 177 patients with 199 CFA lesions treated with EVT using interwoven nitinol stents, because surgical thromboendarterectomy was difficult due to their multiple comorbidities. The 2-year estimate of freedom from restenosis was acceptable at 88.0%. The 2-year freedom rate from major amputation was also high at 99.0%. Moreover, during a median follow-up of 12.0 months, guiding sheaths were inserted via CFAs implanted IWSs in 73 cases, and no patients had cannulation-related complications such as failed hemostasis, fracture of IWS, and stent occlusion.

Impact of Procedural Techniques on Midterm Patency of Fluoropolymer-Based Drug-Eluting Stent Placed in the Femoropopliteal Artery. J Vasc Interv Radiol 2024; 35:259-268. [PMID: 37898458 DOI: 10.1016/j.jvir.2023.10.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 10/16/2023] [Accepted: 10/20/2023] [Indexed: 10/30/2023] Open
Abstract
PURPOSE To investigate the impact of compliance with recommended procedural techniques on the midterm patency of a fluoropolymer-based drug-eluting stent (FP-DES) in the femoropopliteal artery. MATERIALS AND METHODS This retrospective study included 200 femoropopliteal lesions (chronic limb-threatening ischemia, 59%; chronic total occlusion, 41%) in 173 patients (male, 66%; diabetes mellitus, 62%; hemodialysis, 40%) with lower extremity arterial disease who underwent intravascular ultrasound (IVUS)-guided endovascular therapy with FP-DES between January 2016 and July 2021. The primary outcome measure was restenosis, defined as a peak systolic velocity ratio of >2.4 based on the duplex US findings. The association between procedural techniques and incidence of restenosis was investigated using Cox proportional hazards regression models. RESULTS The 2-year cumulative incidence of restenosis was 19.5% (SD ± 3.3). Multivariate analysis revealed that noncompliance with recommended procedural techniques, such as plaque burden at the stent edge of <50%, a minimum stent area (MSA) of >12 mm2, and stent placement within the P1 segment, was independently associated with an increased risk of restenosis (hazard ratios [HRs], 3.22, 4.71, and 4.67 and P = .004, P < .001, and P < .001, respectively). The 2-year restenosis risk for procedures performed in compliance with all 3-technical criteria was 8.4% (SD ± 3.4), whereas the risks for those in compliance with 2-technical criteria or 0- or 1-technical criteria were 25.0% (SD ± 6.2) and 48.6% (SD ± 10.4), respectively. HRs relative to 3-technical criteria compliance were 3.79 (P = .007) and 11.85 (P < .001), respectively. CONCLUSIONS Noncompliance with recommended procedural techniques, including plaque burden at the stent edge of <50%, MSA of >12 mm2, and stent placement within the P1 segment, was significantly associated with an increased risk of 2-year restenosis after FP-DES implantation in the femoropopliteal artery.

Abstract
OBJECTIVE The objective of this study was to summarize whether the application of additional intravascular ultrasound (IVUS) can change the outcomes of endovascular treatment in femoropopliteal atherosclerotic lesions compared with conventional angiography alone based on the existing study and evidence. METHODS Studies published until September 2022 were searched from PubMed, Embase, and Cochrane databases using the methods of combination of Medical Subject Headings and free text words. The outcomes included in these studies were primary patency rate or restenosis rate and freedom from clinically driven target lesion revascularization (cdTLR) rate, and most studies were concerned about the 12-month results. Two independent authors conducted the process of study selection. And the pooled analysis was attempted. RESULTS Finally, the inclusion criteria were met by 4 studies (1 randomized controlled trial and 3 retrospective studies) involving 1160 patients. IVUS played its role in measuring lesions and/or guiding wiring passage. Most of the included studies showed that IVUS could achieve a higher 12-month primary patency rate (from 70% to 90%) and higher 12-month freedom from cdTLR rate (from 83.9% to 94.7%) than angiography. The tentative pooled analysis also showed that IVUS significantly improved the 12-month primary patency rate (OR: 2.21, 95%CI: [1.38-3.55], p=0.001) and the 12-month freedom from cdTLR rate (OR: 1.70, 95%CI [1.04-2.78], p=0.03) compared with angiography alone. CONCLUSIONS Intravascular ultrasound-guided endovascular treatment of femoropopliteal artery lesions may have its own advantages such as higher primary patency rate and freedom from cdTLR rate at 12 months. As a novel technology, IVUS is expected to become another beneficial option to guide clinicians performing endovascular therapy in addition to angiography and may achieve better clinical outcomes. More prospective and high-quality studies are needed in the future to investigate the role of IVUS in the process of femoropopliteal artery lesions endovascular treatment. CLINICAL IMPACT This review summarized a few available studies to promote understanding of IVUS and reveal its potential. This novel technology shows the possibility of achieving better clinical outcomes than angiography in femoropopliteal artery lesions endovascular therapy such as higher 12-month primary patency rate shown in some studies. Currently, it is important to consider suitable technologies applied to individualized treatment. IVUS seems to provide clinicians additional option in clinical practice and benefit patients well in the future. And it needs us to conduct more high-quality studies to explore its roles and advantages in endovascular treatment.

Abstract
AIM This study aimed to reveal whether a larger postprocedural minimum lumen area (MLA) would reduce restenosis risk after endovascular therapy (EVT) using drug-coated balloons (DCBs) in femoropopliteal (FP) lesions. METHODS This retrospective, nonrandomized, single-arm, and multicenter registry analyzed patients with FP lesions undergoing intravascular ultrasound (IVUS)-guided EVT with DCB between 2017 and 2021. The primary outcome was restenosis 1 year after EVT. The association between IVUS-based MLA and restenosis risk was investigated using a generalized propensity score (GPS) method to address imbalance of baseline covariates. The dose-response function of IVUS-measured MLA for restenosis risk was developed using the GPS-adjusted Cox proportional hazards regression model. RESULTS This study enrolled consecutive 489 patients with 595 lesions undergoing DCB treatment. The median MLA (interquartile range) was 13.20 (9.90-16.91) mm2. Kaplan-Meier estimates showed that freedom from restenosis was 84.4% at 1 year. The GPS-adjusted dose-response function showed that MLA was inversely associated with restenosis risk. The upper limit of 95% confidence interval (CI) of the slope was lower than 0 between 10.6 and 17.0 mm2 of MLAs. The 1-year cumulative incidence of restenosis was estimated to be 9.8% (95% CI, 5.8%-13.7%) for the 3rd quartile of MLA (16.91 mm2) versus 18.5% (12.3%-24.1%) for the 1st quartile (9.90 mm2), with a hazard ratio of 0.51 (95% CI, 0.39-0.67; p<0.001). CONCLUSIONS The present GPS analysis suggested that larger IVUS-measured MLA might be associated with lower risk of 1-year restenosis after DCB treatment for FP lesions.

Abstract
Background and Aims Polymer-coated drug-eluting stents (Eluvia) have shown favorable clinical outcomes in real-world registries. There are no reports on recurrent predictors after Eluvia placement based on intravascular ultrasound (IVUS) findings. Methods We analyzed clinical data from the ASIGARU PAD registry, a retrospective, multicenter, observational study that enrolled patients who underwent endovascular therapy for superficial femoral and proximal popliteal arteries lesions using Eluvia or drug-coated balloon. The primary outcome was the identification of recurrent predictors, including IVUS parameters at 12 months. The rate of target lesion recurrence was also assessed. Results IVUS images were obtained in 54 of 65 cases. Seven recurrent cases (13.0%) were observed within 12 months. The random survival forest method presented eight predictive variables of recurrence: Clinical Frailty Scale (CFS), distal stent edge area, distal plaque burden, age, sex, distal external elastic membrane (EEM) area, minimum stent area (MSA), and distal lumen area. Furthermore, the partial dependence plot showed that frailty (CFS ≥ 6), smaller distal stent edge area, higher and lower distal plaque burden, older and younger age, female sex, smaller distal EEM area, smaller MSA, and smaller and larger distal lumen area predicted recurrence after Eluvia placement within 12 months. Conclusion CFS, distal stent edge area, distal plaque burden, age, sex, distal EEM area, MSA, and distal lumen area were significant recurrent predictors after Eluvia placement.

Abstract
Isolated atherosclerotic popliteal lesions (IAPLs) have been considered challenging. This study aimed to investigate the efficacy of endovascular therapy (EVT) using the newer devices for IAPLs. This retrospective multicenter registry analyzed patients with lower extremity artery disease having IAPLs who underwent EVT using the newer devices between 2018 and 2021. The primary outcome was primary patency 1 year after EVT. A total of 392 consecutive patients undergoing EVT for IAPLs were enrolled. The Kaplan-Meier analysis showed that the primary patency and the freedom from target lesion revascularization were 80.9% and 87.8% 1 year after EVT, respectively. The multivariate Cox proportional hazards regression analysis showed that the clinical features that were independently associated with restenosis risk were drug-coated balloon (DCB) use for younger age (< 75 years old; adjusted hazard ratio, 3.08 [95% confidence interval 1.08-8.74]; P = 0.035), non-ambulatory status (2.74 [95% confidence interval 1.56-4.81]; P < 0.001), cilostazol use (0.51 [95% confidence interval 0.29-0.88]; P = 0.015), severe calcification (1.86 [95% confidence interval 1.18-2.94]; P = 0.007), and small external elastic membrane (EEM) area measured by intravascular ultrasound (IVUS) (< 30 mm2) (2.07 [95% confidence interval 1.19-3.60]; P = 0.010). From the univariate analysis, among patients treated with DCB, younger patients (n = 141) were associated with more comorbidities including smoking (P < 0.001), diabetes mellitus (P < 0.001), end-stage renal disease (P < 0.001), history of revascularization (P = 0.046) and small EEM area (P = 0.036), compared to older patients (n = 140). Moreover, smaller post-procedural minimum lumen area measured by IVUS after DCB dilatation was observed in younger patients (12 ± 4 vs. 14 ± 4 mm2, P = 0.033). This retrospective study demonstrated that the current EVT provided an acceptable 1-year primary patency rate in patients with IAPLs. The primary patency was lower following DCB in younger patients, likely due to the higher rates of comorbidities in this patient population.

Abstract
OBJECTIVE To compare the results of endovascular treatment with drug-eluting stents (DES) and drug-coated balloons (DCB) in atherosclerotic lesions in the femoropopliteal artery, as well as to assess restenotic patterns. METHODS Clinical data from 617 cases treated with DES or DCB for femoropopliteal diseases were analyzed in this multicenter, retrospective cohort study. From these, 290 DES and 145 DCB cases were extracted by propensity score matching. Outcomes investigated were 1- and 2-year primary patency, reintervention, and restenotic pattern and its impact on symptoms in each group. RESULTS The primary patency rates at 1 and 2 years in the DES group were superior to those in the DCB group (84.8% and 71.1% vs 81.3% and 66.6%, P = .043), whereas there was no significant difference in freedom from target lesion revascularization (91.6% and 82.6% vs 88.3% and 78.8%, P = .13). Compared with what was measured before the index procedures, exacerbated symptoms, rate of occlusion, and an increase in the occluded length at loss of patency were more frequent in the DES group than in the DCB group. The odds ratios were 3.53 (95% confidence interval, 1.31-9.49; P = .012), 3.61 (1.09-11.9; P = .036), and 3.82 (1.15-12.7; P = .029), respectively. On the other hand, the frequency of an increase in lesion length and requirement of target lesion revascularization were similar between the two groups. CONCLUSIONS Primary patency was significantly higher at 1 and 2 years in the DES than in the DCB group. However, DES were associated with exacerbated clinical symptoms and complicated lesion characteristics at the point of loss of patency.

Abstract
Although various devices and strategies were introduced into endovascular therapy, factors associated with chronic outcomes remain unclear. Therefore, this study aimed to build preliminary data of Japanese femoropopliteal lesions in a period of transition from non-drug to drug technology. This research was a multicenter, prospective, and observational study. A total of 1003 consecutive patients with a mean age of 73.6 ± 8.3 years from 67 institutes were registered from February 2017 to June 2018 in Japan. In addition to the baseline data, angiographic findings affecting primary patency were studied. Lesion length was 16.4 ± 9.6 cm, and chronic total occlusion was found in 42%. Calcified lesions were found in 75% of patients. The 1-year and 2-year freedom from target lesion revascularization were 81% and 75%, respectively, and maximum walking distance showed improvement over the two years (pre; 234 m ± 211 m, 1-year; 402 m ± 241 m, 2-year; 428 m ± 231 m). The independent predictors for primary patency were pre-procedure ankle-brachial index, history of minor amputation, ostium lesion, and drug-coated balloon use. Angiographic analysis revealed that only lesion length and full cover stent were related to primary patency. Two-year freedom from target vessel revascularization was 75% in the Japanese transitional period of drug-eluting devices. Maximum walking distance was improved and well maintained for up to 2-year.

Intravascular ultrasound-based decision tree model for the optimal endovascular treatment strategy selection of femoropopliteal artery disease-results from the ONION Study. CVIR Endovasc 2022; 5:52.

Abstract
BACKGROUND The role of catheter-based imaging in peripheral interventions for lower extremity artery disease (LEAD) has increased with percutaneous interventions. To clarify the relation between intravascular ultrasound (IVUS) information and procedure selection strategy for endovascular treatment therapy (EVT) of the femoropopliteal artery in the real-world clinical settings wherein new endovascular technologies (NETs), including drug-coated balloon (DCB), drug-eluting stent (DES), and covered stent-graft (CS). Our retrospective multicenter analysis examined symptomatic 970 patients treated by EVT for de novo femoropopliteal lesions with IVUS guidance. The decision tree analysis was performed retrospectively to determine the association of IVUS and angiography parameters with the strategy selection of endovascular procedures. We divided the study population according to the developed tree, and identified the most popular strategy selection in each subgroup. We finally examined whether the restenosis risk would be different among respective subgroups of the tree. RESULTS During the study periods, plain old balloon angioplasty, DCB, and bare nitinol stent were most frequently selected (25.3%, 23.9%, and 23.8%, respectively). The drug-eluting stent (DES), covered stent (CS), and spot stent strategies were used in 7.3%, 11.5%, and 8.1%. NETs had the lowest restenosis risk in the overall population. The decision tree had a depth of six branches and divided the patients into 11 subgroups by IVUS and angiography parameters. The restenosis rate was similarly low among these 11 subgroups when the most popular NET in each subgroup was selected (P = 0.94). CONCLUSIONS The use of IVUS data along with angiography data would standardize the selection of endovascular procedures and can improve patency outcomes if NETs are used properly.

Abstract
In this review article, we summarize the clinical benefit of intravascular ultrasounds (IVUS) in the endovascular therapy (EVT) of complex femoropopliteal (FP) lesions. Due to the development of novel FP-dedicated devices, outcomes of FP-EVT have been improved. As a result, revascularization methods for the FP lesions have shifted to EVT. However, the long-term durability in complex FP lesions has not yet reached that of bypass surgery using autogenous vein. Strategies for EVT of complex FP lesions are still inconsistent and have room for improvement. Long-term results generally depend on the patient and lesion backgrounds but are also affected by the quality of the procedure. Previous reports have shown IVUS evaluation can better assess vessel size compared to conventional angiographic evaluation. In contrast to angio-guided EVT, which evaluates vessel size by inner diameter, IVUS can be evaluated it with an external elastic membrane, which leads to the selection of a more appropriate (basically, larger) size device. Conversely, angiographic evaluation underestimates the vessel size, suggesting that it may lead to insufficient result. Furthermore, IVUS can also assess the adequate guidewire route, presence of severe dissection etc. As the evidence so far shows, the use of IVUS may improve the quality of EVT procedure, resulting in improved long-term outcomes. In conclusion, despite the widespread use of IVUS in FP-EVT practice, it still conditionally applied. The purpose of IVUS in the EVT of complex FP lesions should be clarified. More evidence regarding the IVUS in complex FP lesions is needed.

Abstract
This review details the utility of intravascular ultrasound (IVUS) for the management of peripheral artery and venous disease. The purpose of this document is to provide an update in the use of IVUS in peripheral arterial and venous pathology and demonstrate the use of IVUS as a practical diagnostic imaging procedure to evaluate and treat peripheral vascular disorders. IVUS, a diagnostic tool that relies on sound waves to produce precise images of the vessel being evaluated, was originally introduced to the medical community for the purposes of peripheral artery imaging, though it was quickly adapted for coronary interventions with positive outcomes. The utility of IVUS includes vessel measurement, pre- and post-procedural planning, treatment optimisation, and detection of thrombus, dissection or calcium severity. While angiography remains the standard imaging approach during peripheral intervention, multiple observational studies and small prospective trials have shown that in comparison, IVUS provides more accurate imaging detail, which may improve procedural outcomes. IVUS can also address limitations of angiography, including the need to administer contrast medium and eliminate the ambiguity associated with other forms of imaging. This review provides contemporary examples of where IVUS is being used during peripheral intervention as well as representative imaging to serve as a resource for the practising clinician.

Catheter Cardiovasc Interv 2022; 100:687-695. [PMID: 35842776 DOI: 10.1002/ccd.30339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Revised: 04/27/2022] [Accepted: 07/07/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVES The aim of this study was to compare the ability of two different atherectomy modalities, the directional atherectomy system (DAS) and the orbital atherectomy system (OAS), to modify plaque and augment luminal gain as evaluated by angiography and intravascular ultrasound (IVUS) in patients with symptomatic femoro-popliteal peripheral arterial disease (PAD). BACKGROUND Atherectomy is frequently utilized in the treatment of complex PAD. To date, there are no head-to-head comparisons of existing devices and their selection is based mostly on operator preference rather than on supportive data. METHODS This was a single-center, prospective, randomized trial designed to assess the impact of DAS in comparison to OAS on atherosclerotic plaque. Pre- and postatherectomy lesion characterization was performed by angiography and IVUS. Drug-coated balloon (DCB) angioplasty was performed after atherectomy with similar analysis repeated. RESULTS Sixty patients were randomized to undergo either DAS or OAS. Pretreatment angiographic and IVUS characteristics were similar in the DAS and OAS groups. DAS led to a greater reduction in plaque volume throughout the entire lesion (5.9% vs. 1.1%, p = 0.003). This corresponded to a greater increase in total vessel and lumen volume by IVUS (161.5 mm3 vs. 50.2 mm3 , p = 0.001; 178.6 mm3 vs. 47.0 mm3 , p = 0.004, respectively), as well as a reduction in angiographic stenosis (40% vs. 70%, p < 0.001). After DCB, 10 patients required stenting for suboptimal results in the OAS group compared with two in the DAS group (p = 0.021). CONCLUSIONS Compared to OAS, DAS demonstrated a greater plaque volume reduction and luminal gain with significantly fewer stents needed post-DCB.

Abstract
INTRODUCTION To assess whether intravascular ultrasound (IVUS)-guided angioplasty in femoropopliteal lesions would improve clinical outcomes and predict restenosis. EVIDENCE ACQUISITION Studies in which IVUS-guided angioplasty was used for femoropopliteal lesions were searched from the MEDLINE, Embase, Web of Science, and Cochrane databases; articles with the full text were included. The primary endpoint of this study was primary patency at 12 months, while the secondary endpoints were primary patency at 24 months, freedom from target lesion revascularization (TLR) at 12 months, and correlation of restenosis with the distal external elastic membrane (EEM) area, post-intervention minimum lumen area, lesion length, dissection, and calcification. EVIDENCE SYNTHESIS Altogether, 11 observational studies involving 1521 patients (1703 lesions) were analyzed. The quality of the evidence for 7 main outcomes was assessed as "very low" by The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) classification. The mean follow-up period was 1.5 years. The pooled rates were: 78% for 12-month primary patency (95% confidence interval [CI], 0.72-0.83), 74.3% for 24-month primary patency (95% CI, 0.71-0.78), and 80% for 12-month freedom from TLR (95% CI, 0.74-0.86). The 12-month primary patency of IVUS use (relative risk [RR], 2.01; 95% CI, 1.48-2.74) was higher compared to non-IVUS use. The minimum lumen (stent) area (standard mean difference (SMD) = -0.30; 95% CI, -0.46 to -0.15) and dissection (OR 1.58; 95% CI, 1.01-2.49, P = 0.047), were associated with midterm patency in terms of restenosis. CONCLUSIONS In IVUS-guided angioplasty in patients with femoropopliteal lesions, the minimum lumen (stent) area and dissection were associated with restenosis. Nevertheless, there is limited and heterogeneous evidence regarding the usefulness and Predictability of IVUS in patients with peripheral arterial disease in the femoropopliteal artery, especially in long-term patency and as a predictor of declining patency. The optimal role of IVUS in such patients should be elucidated in the future.

Abstract
PURPOSE Drug-coated balloons (DCBs) are commonly used for endovascular treatment of femoropopliteal lesions. Here, we employed intravascular ultrasound (IVUS) to investigate the predictors of restenosis after DCB treatment. METHODS This retrospective and single-center study was performed to examine 1-year primary patency after DCB treatment and to identify the risk factors for restenosis by analyzing clinical characteristics, angiographic findings, and IVUS measurements. We included 111 consecutive patients undergoing DCB treatment for de novo femoropopliteal lesions at our hospital from July 2018 to March 2020. RESULTS The primary patency rate was found to be 80.0% at 1 year. The Cox proportional hazard multivariate analysis revealed that restenosis was independently associated with chronic total occlusion (CTO; p < 0.001), circumferential calcification (p = 0.023), and smaller postprocedural minimum lumen area (MLA; p = 0.036). Furthermore, receiver operating characteristic curve analysis showed that the cutoff value of postprocedural MLA to prevent restenosis was 12.7 mm2, with an area under the curve of 0.774 (p< 0.001). The multivariate analysis indicated that patients with a postprocedural MLA below 12.7 mm2 (n = 44) had a significantly smaller distal reference vessel size (p < 0.001) compared to those with a postprocedural MLA over 12.7 mm2 (n = 67). CONCLUSIONS Restenosis after DCB treatment was shown to correlate with CTO, circumferential calcification, and postprocedural MLA as evaluated by IVUS. Moreover, smaller vessel sizes might represent a particular challenge to the DCB strategy due to the difficulty of restoring a sufficient postprocedural lumen area by balloon dilatation.

Abstract
Both polymer-coated paclitaxel-eluting stents (PC-PESs) and drug-coated balloons (DCBs) are used in conjunction with endovascular therapy (EVT) for the treatment of peripheral artery disease (PAD). We aimed to identify the risk factors for the loss of patency following the use of PC-PES and DCB in a real clinical setting. We assessed the multi-center registry data of 151 lesions from 151 patients who underwent EVT for symptomatic PAD in the superficial femoral and proximal popliteal arteries using PC-PES or DCB. One-year primary patency (PP) and clinically driven target lesion revascularization (CD-TLR) were evaluated using Kaplan-Meier analysis. The predictive risk factors for 1-year outcomes were analyzed using the random survival forest method. PC-PES and DCB were used in 65 (43.0%) and 86 (57.0%) cases, respectively. There were no significant differences in 1-year PP or freedom from CD-TLR between PC-PES and DCB. PP occurred in 85.4% and 80.2% of cases in the PC-PES and DCB groups, respectively (log-rank p = 0.65), while freedom from CD-TLR was noted in 92.7% and 94.1% of cases in the PC-PES and DCB groups, respectively (log-rank p = 0.73). In order of importance, a Clinical Frailty Scale score ≥ 6, female sex, lower proximal vessel diameter, lower body mass index, and younger and older age were identified as predictive risk factors of restenosis in the PC-PES group. Peripheral artery calcification scoring system grade of ≥ 2, post-dissection pattern ≥ D, lower proximal and distal vessel diameter, and lesion length ≥ 100 mm were identified as predictive risk factors of restenosis, in order of importance, in the DCB group. Both PC-PES and DCB were associated with favorable clinical outcomes within 1 year in patients with femoropopliteal artery disease. Furthermore, several factors that could predict restenosis within 1 year following the use of each device were detected.

Abstract
PURPOSE To determine the predictive factors for in-stent restenosis (ISR) following stent-supported endovascular therapy (EVT) with intravascular ultrasound (US) evaluation for femoropopliteal chronic total occlusion. MATERIALS AND METHODS This was a single-center, retrospective, observational study. The study included 276 lesions in 251 patients who underwent stent-supported EVT with intravascular ultrasound evaluation for femoropopliteal chronic total occlusion from July 2012 to June 2019. The wire passage route was assessed using intravascular US, and lesions were classified accordingly into 2 groups: intraluminal and subintimal passage. In this study, the intraluminal group was further divided into 3 subgroups by severity of calcification: none, <180°, and ≥180° circumferential. The subintimal group was further divided into 2 subgroups: subintimal passage without or with calcification. The primary outcome measure was ISR. Cox proportional hazards regression was used to determine the association of clinical characteristics with ISR rates. RESULTS The mean follow-up period was 19 months ±16, during which time ISR was observed in 31% of lesions. After multivariate analysis, an increased degree of plaque burden (hazard ratio [HR] = 1.101) and subintimal passage with calcification (HR = 3.408) were associated with an increased risk of ISR; a larger distal external elastic membrane area (HR = 0.898) and use of a stent graft (HR = 0.130) were significantly associated with a reduced risk of ISR. CONCLUSIONS This study revealed that factors associated with ISR after stent-supported EVT with intravascular US evaluation were distal external elastic membrane area, plaque burden, subintimal passage with calcification, and use of a stent graft.
