This database is composed of 7 fields including treatment of aneurysms, chronic arterial occlusive disease, acute arterial occlusive disease, vascular injury, complication of previous vascular reconstruction, venous diseases, and other vascular treatments. The number of vascular treatments in each field was 23,826, 17,100, 4,947, 2,369, 674, 54,023, and 51,521, respectively. In the field of aneurysm treatment, 20,369 cases of abdominal aortic aneurysm (AAA) including common iliac aneurysm were registered, and 63.3% were treated by endovascular aneurysm repair (EVAR). Among AAA cases, 1,739 (8.5%) cases were registered as ruptured AAA. The operative mortality rates of ruptured and un-ruptured AAA were 15.0%, and 0.6%, respectively. 43.8% of ruptured AAA were treated by EVAR, and the EVAR ratio was gradually increasing, but the operative mortality rates of open repair and EVAR for ruptured AAA were 12.6%, and 15.4%, respectively. Regarding chronic arterial occlusive disease, open repair was performed in 8,026 cases, including 1,250 distal bypasses to the crural or pedal artery, whereas endovascular treatment (EVT) was performed in 8,879 cases. The EVT ratio was gradually increased at 51.9%. Varicose vein treatment was decreased in 42,313 cases (1.9% less than in 2018), and 79.8% of the cases were treated by endovenous thermal ablation (ETA) including endovenous laser ablation (EVLA) and radio-frequency ablation (RFA). Regarding other vascular operations, 47,605 cases of vascular access operations and 1,703 lower limb amputation surgeries were included. <b>Conclusions:</b> The number of vascular treatments increased since 2011, and the proportion of endovascular procedures increased in almost all fields of vascular diseases, especially EVAR for AAA, EVT for chronic arterial occlusive disease, and ETA for varicose veins.

Nevertheless, the efficacy of their concomitant treatments is still controversial for a decade. In the guidelines of the Japanese Society of Phlebology, concomitant phlebectomy of tributary varicose veins with ETA is described that it is not recommended officially. In our hospital, RFA without concomitant phlebectomy of tributary varicose veins accounts for 74% of the RFA cases and it shows a relatively higher percentage than other institutions in Japan. The data of RFA without concomitant phlebectomy of tributary varicose veins are evenly matched in RFA with concomitant treatments in our data concerning recurrence, remnants, endovenous heat-induced thrombosis (EHIT), and complications. This article provides the conclusion that it would be acceptable to perform isolated RFA compared to RFA with concomitant phlebectomy or foam sclerotherapy of tributary varicose veins in short- and mid-term periods. In addition, concomitant treatments might contribute to rapid improvement of the short-term and better long-term outcomes, not to mention cosmetic problems that are not identified demonstrably.
