脑血管意外是经皮冠状动脉介入治疗（percutaneous coronary intervention，PCI）后最严重的并发症之一。研究表明，高龄、高血压、糖尿病、卒中史、肾脏衰竭、心力衰竭、主动脉内球囊反搏（intra-aortic bal oon pump，IABP）、紧急冠状动脉造影等是PCI后脑血管意外的危险因素。PCI后发生脑血管意外的患者住院时间延长，住院费用增加，致死致残率高，多数患者在出院后有持久的神经系统缺陷。研究认为可以通过优化药物治疗，减小导管口径，避免低血压等措施来降低脑血管意外的发生率。%Percutaneous coronary intervention-related cerebrovascular accidents (PCI-CVA) is reported to occur in 0.18% to 0.44% of all PCI procedures, which is one of the most debilitating complications. An advanced age, arterial hypertension, diabetes mellitus, history of stroke, congestive heart failure, renal failure, the use of an intra-aortic balloon pump, coronary angiography performed under emergency conditions have been identiifed as risk factors for PCI-CVA. PCI-CVA patients suffer from longer hospital stay, higher expenses, higher mortality and persistent neurological defects. We can optimize drug therapy, use smaller-caliberguides, and avoid hypotension to reduce the PCI-CVA's incidence.
