title: Atherosclerotic aneurysm of the intrathoracic segment of the subclavian artery: a case report.
abstract: True aneurysms of the intrathoracic segment of the subclavian artery are extremely rare. Atherosclerosis is the most common etiology. The surgical approach and timing of repair remain controversial. We successfully treated a patient with a large proximal subclavian artery aneurysm which was secondary to atherosclerosis. The patient was asymptomatic for 30 years as the aneurysm enlarged. Three-dimensional computed tomography provided the most useful information regarding anatomy of the cervical vasculature. The patient underwent closure of the inlet port of the aneurysm and repair using a 6-mm Dacron bypass graft (Gelsoft , VASCTEK, Scotland) via a minimally invasive surgical approach.
