Carotid artery aneurysm of granulomatous origin.
A native of the Western Caroline Islands presented with a granulomatous aneurysm of the right common carotid artery measuring 7 to 8 cm, which was resected and replaced with a reversed segment of saphenous vein. Adequacy of the collateral circulation to the brain was established by occlusion of the common carotid artery with local anesthesia. This was followed by definitive operation with general endotracheal anesthesia and induced hypertension. Although tuberculosis was the most likely etiologic agent, sarcoid could not be ruled out. Granulomatous aneurysms of the common carotid are extremely rare, and if this case was sarcoid in origin, it is the first such case reported. Only one other similar aneurysm could be found in the literature. Of the various methods of reconstruction of the common carotid artery reported, autogenous reversed saphenous vein is recommended strongly.
