"Grape cluster" aneurysm of the right subclavian artery: an unusual manifestation of fibromuscular dysplasia.
Aneurysmal lesions affecting the intrathoracic portion of the subclavian artery are rare. We present a patient who had a right hemispheric stroke and transient ischemic attacks caused by a complex right subclavian artery aneurysm with unusual morphological features. Successful surgical repair of this lesion is described along with pathological studies demonstrating fibromuscular dysplasia. The occurrence of such lesions and their management is reviewed.
