Popis: 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.
