Introduction:

the management and treatment of a spontaneous carotid aneurysm using a minimally invasive endovascular technique is a rare procedure. This case resulted in the exclusion of the aneurysm from circulation, maintaining the patency of the internal carotid artery and its terminal cerebral branches.

Case report:

we present the case of a 61-year-old man with a history of arterial hypertension and six previous cerebrovascular events with brain micro-injuries without neurological focus. Angiographic investigation revealed an aneurysm of the left internal carotid artery, cervical segment (C1) of wide neck, saccular, possibly causing the patient's symptoms.

Discussion:

definitive percutaneous endovascular management of the aneurysm was indicated using standard technique and micro malted stent placement (CGuard™), covering the neck and achieving immediate exclusion of the carotid aneurysm. Follow-up one month after the procedure confirmed closure, carotid patency and resolution of symptoms.
