Open surgical and endovascular treatment of extracranial internal carotid artery aneurysms.

ABSTRACT

Internal carotid artery (ICA) aneurysms are rare. The symptoms are related to cerebral embolization, local compression and rupture. Options for treatment include open surgery or endovascular treatment with a covered stent. We report a case of a 67 year old woman with bilateral idiopathic internal carotid artery aneurysms, found during the diagnostic evaluation for an episode of syncope. The right ICA aneurysm was treated with resection and end-to-end anastomosis of the ICA. There were no perioperative complications. Six months later the patient underwent endovascular repair of left carotid artery aneurysm with a covered stent. There were no complications in postoperative period. Treatment options for ICA aneurysms are surgical or endovascular, depending of size, location and anatomic relation to surrounding structures.
