Symptomatic patients requiring intervention for revascularization of chronic occlusion of the internal carotid artery, meeting the surgical criteria. 3. Patients able to undergo magnetic resonance imaging without any contraindications.

Patients with implants or prostheses in the head or neck region. 3. Patients with arterial occlusion in the head and neck due to non-atherosclerotic causes such as arteritis or radiation therapy. Interventional Cohort 1. Patients with concomitant cerebral vascular diseases such as aneurysms, arteriovenous malformations, or fistulas. 2.
