This is an annual report indicating the number and early clinical results of annual vascular treatments performed by vascular surgeons in Japan during 2011, as analyzed by database management committee (DBC) members of the Japanese Society for Vascular Surgery (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 from National Clinical Database (NCD), including the number of treatments and early clinical results such as operative and in-hospital mortality. Given that NCD data were prospectively built by a nationwide registration, this annual report reports prospective clinical data.

Results: In total 71,707 vascular treatments including open repairs and endovascular treatments were registered by 992 institutions in 2011. This database is composed of 7 fields including treatment of aneurysms, chronic arterial occlusive disease, acute arterial occlusive disease, vascular injury, complication of vascular reconstruction, venous diseases, and other vascular treatments. The number of vascular treatments in each field was 17,524, 11,278, 3,799, 1,030, 1,615, 19,371, and 17,510, respectively. In the field of aneurysm treatment, 13,218 cases with abdominal aortic aneurysms (AAA) including iliac aneurysms were registered, including 1,253 ruptured cases. Forty-five percent of AAA cases were treated by stent graft. The operative mortality of ruptured and non-ruptured AAA was 18.8% and 0.8%, respectively. Regarding chronic arterial occlusive disease, open repair was performed in 7,115 cases including 984 distal bypasses to the crural or pedal artery, whereas endovascular procedures were performed in 4,163 cases. For acute arterial occlusive disease, more than 90% of cases were treated with open repair. Vascular injury treatment included 81 venous injury cases and 949 arterial injury cases, and 60% of arterial injuries were iatrogenic. Treatment for complication of previous vascular treatment included 445 cases of graft infections, 240 cases of anastomotic aneurysms, and 811 cases of graft revision operations. The venous treatment included 18,864 varicose vein treatments, 343 cases with lower limb deep venous thrombosis, and 67 cases with vena cava reconstructions. Regarding other vascular operations, 16,296 cases of vascular access operations and 1,037 amputation surgeries are included.

Conclusions: This vascular surgery database indicates not only the number of vascular treatments but also the early clinical outcomes for each treatment procedure, thereby representing a useful source for researching the clinical background of poor outcomes and for finding improvements in the quality of treatment. Continuing this work will provide information regarding changing the treatment modality in response to the changing structure of disease and societal needs.
