CAROTID-ARTERY REVASCULARIZATION FOLLOWING CRUTCHFIELD CLAMP PLACEMENT - REPORT OF 2 CASES

Several types of adjustable clamp have been widely utilized to gradual ly occlude the carotid artery for the treatment of various intracrania l vascular lesions. A fairly large number of patients, many of whom ha ve not been adequately followed, have these clamps still in place. The authors report two patients, initially treated with a Crutchfield cla mp for an intracranial aneurysm, in whom carotid artery system revascu larization occurred through the clamp many years later, leading to con tinued filling of the aneurysm. Recommendations are given on monitorin g patients with Crutchfield clamps in order to minimize long-term comp lications.
