Carotid artery pseudoaneurysm after carotid endarterectomy: case report

Extracranial carotid artery aneurysms are quite rare. They account for 0.4% to 4% of all peripheral arterial aneurysms. Precise treatment is essential in order to avoid neurological complications of aneurysms. A 67-year-old male patient was admitted to the cardiology outpatient clinic of our hospital three months ago, with complaints of chest pain during exertion. The effort test of the case revealed a positive result, and coronary angiography revealed stenosis in the coronary arteries. The carotis doppler ultrasonography revealed plaque in the left internal carotid artery, causing 80% narrowing in the lumen. Four vessels were determine to be bypassed, and a left carotid endarterectomy was applied in the same session. Swelling and cyanosis were present in the patient’s neck two days after the operation. The control doppler ultrasonography revealed the development of an aneurysm in the left internal carotid artery. The patient was operated on again one week after the first operation, and end-to-end anastomosis was applied with a saphenous vein interposition graft. The decision was made for follow-ups with doppler ultrasonography controls in six-month intervals
