A Case of Dacron Graft Aneurysm 18 Years after Left Subclavian Artery-Descending Aortic Bypass / 日本心臓血管外科学会雑誌

ABSTRACT

Dacron grafts have made great progress and the material has become almost perfect recently. However, we encountered a rare case of a late-graft complication. A 34-year-old man was operated on for coarctation of the aorta in July 1982. Left subclavian artery-descending aortic bypass was performed using a Cooley double velour knitted graft. Eighteen years later, the patient was admitted to our hospital with an abnormal shadow in his chest X-ray. Angiography and computed tomography demonstrated a non-anastomotic aneurysm of the graft. Under cardiopulmonary bypass and deep hypothermic circulatory arrest, reoperation with a woven Dacron graft was successfully performed. This case suggests that it is important to follow up patients with implanted Dacron arterial prostheses because of the potential for rupture.
