[Surgical treatment of right subclavian aneurysm--a case report]

A case of arteriosclerotic aneurysm of right subclavian artery is reported. The patient was 74 years old male. A huge arteriosclerotic aneurysm was found at the origin of right subclavian artery. Calcification of thoracic aorta and arch vessels was prominent. Under the temporary bypass between brachiocephalic artery and right common carotid artery, replacement of the aneurysm with 8 mm Dacron graft was successfully performed. To avoid the systemic embolism, partial clamp was applied to intact arteries. As the perfusion of the brain was maintained through the temporary bypass during the reconstruction of right common carotid and subclavian arteries, intracranial complication was prevented.
