2016 JAPAN Critical Limb Ischemia Database (JCLIMB) Annual Report

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 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 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 EVT. In 2016, 1,092 CLI limbs (male 755 limbs: 70%) were registered by 91 facilities. ASO has accounted for 98% of the pathogenesis of these limbs. In this manuscript, the background data, the early prognosis, and 6-months’ prognosis of the registered limbs are reported.
