One Case of Takayasu Arteritis that Resulted in Anastomotic Aneurysm 26 Years After Bypass Occlusion

Abstract

A 65-year-old woman with Takayasu arteritis had the chief complaint of a pulsatile mass in the right lower abdomen. As the result of the detailed examinations, the diagnosis was an anastomotic aneurysm at the external iliac artery–axillary artery bypass graft anastomotic site. The graft had occluded 26 years ago. An endovascular repair was performed successfully. As Takayasu’s arteritis is associated with low age of morbidity and favorable long term prognosis under treatment, long-term observation is necessary. The risk of an anastomotic aneurysm increases with time, and monitoring of the anastomosis is needed even if the bypass is occluded.
