Abstract
Since 2013, the Japanese Society for Vascular Surgery started the project of nationwide registration and tracking database for patients with critical limb ischemia (CLI) treated by vascular surgeons. The purpose of this project is to clarify the current status of the medical practice for the patients with CLI to contribute to the improvement of the quality of medical care. This database, called JAPAN Critical Limb Ischemia Database (JCLIMB), is created on the National Clinical Database (NCD) and collects the data of patients' background, therapeutic measures, early results, and long-term prognosis as long as five years after the initial treatment. The limbs managed conservatively are also registered in JCLIMB, together with those treated by surgery and/or endovascular treatment. The basic and early prognostic data of CLI, registered during the four years from 2013 to 2016, have been reported as annual reports. In this paper, for the purpose of clarifying the picture of clinical practice of CLI in Japan, we have compiled these data over the past four years.
