Abstract

Background Sudden internal carotid artery (ICA) occlusive vasospasm is a serious complication of intracranial aneurysm embolization. Conventional spasmolysis with papaverine yields a generally poor outcome. We believe that arterial infusion of lidocaine may offer a better outcome.

Materials and Methods We retrospectively reviewed the outcome of patients treated with either papaverine or lidocaine infusion for vasospasm during embolization.

Results 14 patients undergoing intracranial aneurysm embolization had a ICA occlusive vasospasm. Among the 8 patients who received conventional treatment with papaverine the vasospasm improved partially in 5. In 3 cases, treatment was ineffective. 6 of the patients died within 3 days. 2 patients developed hemispheric infarction and underwent a decompressive craniectomy and subtotal resection of the infarct; 1 of these 2 patients died after 4 months and the other was severely disabled. In the 6 patients treated with lidocaine, spasmolysis and subsequent aneurysm treatment was succesful in 5. In 1 patient who had preoperative stenosis of the carotid artery proximal to the aneurysm spasmolysis failed.

Conclusions ICA occlusive spasm is an extremely serious and often lethal complication in embolization of intracranial aneurysms. Conventional treatment with papaverine has a poor outcome, whereas arterial infusion of lidocaine may achieve better results.
