Thrombus Formation: Structure and Evolution in Intracranial Aneurysms Treated by Balloon Occlusion
Nine Patients with intracavernous (N=S) or supraclinoid (n=4) carotid aneurysms were treated by occlusion of the ipsilateral carotid artery with detachable ballons placed as near the origin of each aneurysm as possible. All patients had serial evaluation with CT scans, angiography, and magnetic resonance (MR). Since not all of the nine patients were examined with MR exactly at the same follow up interval, patients were divided into those studied pretreatment (n = 6), within 48 hours of treatment (n = 6), 5–10 days after treatment (n = 4), 4–6 weeks after treatment (n = 4), and at greater than 11 months after treatment (n = 4).
