Aneurysms of the extracranial carotid arteries are uncommon vascular lesions. We report a case of giant extracranial internal carotid artery aneurysm and its repair with an autogenic double layer jugular venous patch. A 46-year-old female patient had a growing mass in her neck for two years. On physical examination, a pulsatile mass was palpated under the sternocleidomastoid muscle between the mandibular angle and the mastoid process. Angiographic examination showed a saccular aneurysm of the internal carotid artery, measuring 6x8 cm, starting 1 cm after the carotid artery bifurcation and ending at the cranial base. The sac was not completely excised to avoid damage to the vagus and ansa cervicalis nerves which were attached to the aneurysmal sac. Then, a double layer jugular venous patch was sutured to the defect on the vessel wall. On control examinations in the first postoperative month, the patient had no complaints and normal blood flow pattern was observed in Doppler ultrasonography and control angiography. Partial aneurysmectomy with double layer venous patch repair is an appropriate alternative in extracranial internal carotid artery aneurysms with cranial nerve attachment to the aneurysmatic sac.
