Objectives: This is an annual report indicating the number and early clinical results of annual vascular treatment performed by vascular surgeon in Japan in 2016, as analyzed by database management committee (DBC) members of the JSVS.
Materials and Methods: To survey the current status of vascular treatments performed by vascular surgeons in Japan, the DBC members of the JSVS analyzed the vascular treatment data provided by the National Clinical Database (NCD), including the number of treatments and early results such as operative and hospital mortality.
Results: In total 136,414 vascular treatments were registered by 1,070 institutions in 2016. 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 21,653, 17,560, 4,983, 2,557, 846, 54,462 and 34,353, respectively. In the field of aneurysm treatment, 19,144 cases of abdominal aortic aneurysm (AAA) including common iliac aneurysm were registered, and 60.3% were treated by endovascular aneurysm repair (EVAR). Among AAA cases, 1,714 (9.4%) cases were registered as ruptured AAA. The operative mortality of ruptured and unruptured AAA was 15.7%, and 0.6%, respectively. 35.9% of ruptured AAA were treated by EVAR, and the EVAR ratio was gradually increasing, but the operative mortality of open repair and EVAR for ruptured AAA was 15.8%, and 15.3%, respectively. Regarding chronic arterial occlusive disease, open repair was performed in 9,303 cases, including 1,329 distal bypasses to the crural or pedal artery, whereas endovascular treatment (EVT) was performed in 8,257 cases. The EVT ratio was gradually increased at 47.0%. The number of varicose vein treatment tremendously increased to 52,639, and 68.5% of the cases were treated by endovenous laser ablations (EVLA). Regarding other vascular operations, 32,779 cases of vascular access operations and 1,411 lower limb amputation surgeries were included.
Conclusions: The number of vascular treatments increased since 2011, and the proportion of endovascular procedures increased in almost all field of vascular diseases, especially EVAR for AAA, EVT for chronic arterial occlusive disease, and EVLA for varicose veins.

Objectives: This is an annual report indicating the number and early clinical results of annual vascular treatment performed by vascular surgeon in Japan in 2015, as analyzed by database management committee (DBC) members of the JSVS.
Materials and Methods: To survey the current status of vascular treatments performed by vascular surgeons in Japan, the DBC members of the JSVS analyzed the vascular treatment data provided by the National Clinical Database (NCD), including the number of treatments and early results such as operative and hospital mortality.
Results: In total 124,299 vascular treatments were registered by 1,038 institutions in 2015. 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 22,041, 15,671, 4,779, 2,313, 857, 48,837, and 29,801, respectively. In the field of aneurysm treatment, 18,907 cases of abdominal aortic aneurysm (AAA) including common iliac aneurysm were registered, and 57.6% were treated by endovascular aneurysm repair (EVAR). Among AAA cases, 1,850 (9.8%) cases were registered as ruptured AAA. The operative mortality of ruptured and un-ruptured AAA was 16.0%, and 0.6%, respectively. 33.6% of ruptured AAA were treated by EVAR, and the EVAR ratio was gradually increasing, but the operative mortality of open repair and EVAR for ruptured AAA was 16.6%, and 14.5%, respectively. Regarding chronic arterial occlusive disease, open repair was performed in 8,230 cases, including 1,194 distal bypasses to the crural or pedal artery, whereas endovascular treatment (EVT) was performed in 7,441 cases. The EVT ratio was gradually increased at 47.4%. Venous treatment including 47,046 cases with varicose vein treatments and 531 cases with lower limb deep vein thrombosis were registered. Regarding other vascular operations, 29,801 cases of vascular access operations and 1,511 lower limb amputation surgeries were included.
Conclusions: The number of vascular treatments increased since 2011, and the proportion of endovascular procedures increased in almost all field of vascular diseases, especially EVAR for AAA, EVT for chronic arterial occlusive disease, and endovenous laser ablation (EVLA) for varicose veins.

Since 2013, the Japanese Society for Vascular Surgery has started the project of nationwide registration and tracking database for patients with critical limb ischemia (CLI) who are treated by vascular surgeons. The purpose of this project is to clarify the current status of the medical practice for patients with CLI to contribute to the improvement of the quality of medical care. This database, called JAPAN CLI Database (JCLIMB), is created on the National Clinical Database and collects data of patients’ background, therapeutic measures, early results, and long-term prognosis as long as 5 years after the initial treatment. The limbs managed conservatively are also registered in the JCLIMB, together with those treated by surgery and/or endovascular treatment. In 2018, 1,145 CLI limbs (male 758 limbs, 66%) were registered by 90 facilities. Arteriosclerosis obliterans has accounted for 97% of the pathogenesis of these limbs. In this manuscript, the background data, ischemic status, treatment, and the early prognosis (within 1 month) of the registered limbs are reported.
