Abstract | BACKGROUND AND PURPOSE: MATERIALS AND METHODS: RESULTS: Angiography showed severe proximal vasospasm in 1 patient, proximal and distal in 3 patients, and distal in 3 patients. There was also moderate proximal vasospasm in 4 patients, proximal and distal in 1 patient, and distal in 1 patient. Complete occlusion of the aneurysm was achieved in 5 patients, incomplete occlusion in 3 patients, and a small neck remnant in 2 patients. Final angiograms also demonstrated complete clearance of a proximal spasm in 4 patients, and complete clearance of proximal and distal spasms in another 4 patients. Mean initial dose of nimodipine was 1.375 mg, and mean continuous infusion dose was 1.275 mg (mean total dose, 2.65 mg). No medical complications related to extended infusion of nimodipine occurred. CONCLUSION: In this small series, extended intra-arterial infusion of nimodipine up to the end of the embolization procedure was effective and safe in patients with a ruptured aneurysm and associated vasospasm. This technique seems to increase the security of the procedure as well as force further vasorelaxation when the endovascular route is used to treat both the aneurysm and vasospasm in a single step.
