두개강외 경동맥류 3예 치험보고 = Extracranial Carotid Artery Aneurysms

다국어 초록 (Multilingual Abstract)

Aneurysms of the extracranial carotid arteries are rare vascular lesions but serious complications may result, eg. Rupture, thrombosis or ernboli. The majority of carotid aneruysms are due to atheroscleosis and the most common presenting manifestation is a painful pulsating mass in the neck. Most extracranial carotid aneurysms are confined to the level of the bifurcation and proximal segment of the internal carotid artery, and direct construction is preferable to ligation. Generally, surgical treatment is direct toward aneurysm resection with restoration of arterial continuity, while avoiding neurological complications from either low flow or thromboembolism. Routine use of an intraluminal shunt to maintain cerebral blood flow during reconstruction of the carotid artery has been advocatd in the past but may not be necessary.
In the past 3 years the authors have experienced 3 cases of extracranial carotid artery aneurysms, who are all female and were treated surgically, successfully. The etiologies were atherosclerosis in all 3 cases and one non-specific inflammatory change in carotid artery was combined. The diagnosis was made by arteriography, CT and ultrasonogram. Each aneurysms were exposed through vertical incision, excised, and both ends were anastomosed with or without Goretex graft. Intraluminal shunt was used in one case and other 2 cases were tolerable to clamping of carotid artery. No neurologic deficits were developed. All patients were recovered uneventfully and are followed for 1 to 2 years without any complications.
