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.

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
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
Background The subintimal approach (SA) is widely used in endovascular therapy for femoropopliteal chronic total occlusion lesions. However, when compared with the intraluminal approach (IA), the safety and efficacy of SA in real‐world practice are not well characterized. Furthermore, there is a paucity of data on the clinical impact of subintimal and intraluminal wire passage (SWP and IWP, respectively) assessed by intravascular ultrasound. Methods and Results From the IVORY (Intravascular Ultrasound‐Supported Endovascular Therapy in Superficial Femoral Artery) registry, this study included 500 patients undergoing endovascular therapy for femoropopliteal chronic total occlusion lesions (SA, n=67; IA, n=433; and SWP, n=186; IWP, n=314). The primary end point was the cumulative 1‐year incidence of restenosis. The rate of perioperative complications was also assessed. Propensity score matching analysis was performed to adjust for the intergroup differences. After propensity score matching, the final study population consisted of 59 pairs (SA, n=59; IA, n=348) and 170 pairs (SWP, n=170; IWP, n=293), respectively. Cumulative 1‐year incidence of restenosis was comparable between the SA and IA groups (41.0% versus 43.4%, P=0.40). No significant difference in 1‐year restenosis rate between the SWP and IWP groups was observed (48.2% versus 40.8%, P=0.40), although the SWP group tended to be a higher rate of perioperative complications than the IWP group (8.2% versus 4.1%, P=0.07). Conclusions At 1 year, both SA and IA showed acceptable results for femoropopliteal chronic total occlusion lesions. Cumulative 1‐year incidence of restenosis was not significantly different between SWP and IWP, whereas perioperative complications occurred more frequently in SWP than in IWP.

Feasibility of using the balloon backed-up microcatheter technique to treat superficial femoral artery occlusion under extra-vascular ultrasound guidance via radial access. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2021; 40S:162-166.

Abstract
BACKGROUND Endovascular treatment (EVT) of superficial femoral artery (SFA) lesions that can be reached through transradial access (TRA) has often been performed due to its low invasiveness. For complex lesions such as chronic total occlusion (CTO) treated via TRA, EVT is still challenging due to poor device backup and guidewire operability. However, TRA might be preferred in patients with a high risk of bleeding or restricted access sites. CASE SERIES Both patients were diagnosed with peripheral artery disease and had an occlusion in one of their SFAs. They were treated using the balloon backed-up microcatheter technique (BBQ), a novel technique devised by us to treat patients with CTO through TRA. No complications were observed in either patient; therefore, we consider that both the procedures using this technique were successful. CONCLUSIONS We devised a technique that improved the backup of devices and maintained the torque response of the guidewire. This is because the 0.035-inch balloon catheter was anchored in the blood vessel and the microcatheter was trapped inside the monorail lumen of a 0.035-inch balloon catheter without crushing the lumen of the microcatheter. We introduce this technique in our report.

Heart Vessels 2021; 36:646-653. [PMID: 33392645 DOI: 10.1007/s00380-020-01740-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Accepted: 11/20/2020] [Indexed: 11/30/2022]
Abstract
The optimal revascularization for in-stent occlusion (ISO) lesions after femoropopliteal (FP) bare-nitinol stenting has not been established. We, therefore, investigated the comparison between drug-coated stent (DCS) implantation and bypass surgery (BSX) for ISO lesions after FP bare-nitinol stenting. This study was a dual-center, observational study from January 2004 to December 2015. A total of 172 ISO lesions were observed, and after excluding 120 ISO lesions, 52 ISO lesions (50 patients; mean age, 71.0 ± 9.2 years; male, 59.6%) after FP bare-nitinol stenting were enrolled. The included patients with clinical symptoms underwent either DCS implantation (n = 28) or BSX (n = 22). The primary endpoint was recurrent in-stent restenosis (ReISR); secondary endpoints were recurrent target lesion revascularization (ReTLR), recurrent occlusion (reocclusion) and major adverse limb events (MALE), and perioperative complications (POCs), respectively. ReISR or reocclusion was defined as ISR or occlusion after TLR. Stent restenosis was defined as a peak systolic velocity ratio (PSVR) > 2.4 on a duplex scan or ≥ 50% stenosis on angiography. Graft restenosis was defined as a PSV > 300 cm/s and velocity ratio 3.5 or uniformly low PSV < 45 cm/s throughout the entire graft based on graft surveillance. The mean follow-up period was 36.6 ± 25.5 months. At 2 years, the rates of freedom from ReISR, ReTLR, and MALE were not significantly different between the DCS implantation and BSX groups (68.9% vs. 73.7%, p = 0.81; 84.7% vs. 73.7%, p = 0.45; 84.7% vs. 78.6%, p = 0.60, respectively). However, the freedom from reocclusion rate was significantly lower in the DCS implantation group (81.6% vs. 100%, p = 0.04). The occurrence of POCs was not significantly different between the DCS implantation and BSX groups (7.1% vs 4.2%, p = 1.0). Although BSX was the gold-standard therapy for ISO lesions after FP bare-nitinol stenting, DCS implantation might be a good option because the rates of freedom from ReISR, ReTLR, and MALE were similar.
