Prevention and treatment of cerebral complications in patients with carotid stenosis in perioperative period

Objective To investigate the causes of and prevention for cerebral complications in perioperative period in patients with carotid stenosis. Methods The causes and treatment of cerebral complications among 133 cases of carotid stenosis during perioperative period from May 2004 to Jun 2009 were analysed retrospectively. Results Among 133 cases, 94 cases underwent carotid endarterectomy (CEA) and 39 cases had carotid artery stenting(CAS). Cerebral complications developed in 16 cases including 3 cases of more than two attacks. 5 cases suffered from tansient ischemia attacks (TIA)or cerebral ischemia before operation. 5 developed TIA or cerebral hyperperfusion syndrome (CHPS) among those undergoing CEA and 4 developed TIA or CHPS among CAS cases. During postoperative period, 8 cases developed TIA, CHPS,cerebral infarction or cerebral hemorrhage. Conclusions Prevention and treatment of cerebral complications is extremely important durning surgical therapy of carotid stenosis.
