CAS围手术期卒中发生风险因素分析

Analysis of Perioperative Stroke Risk Factors in Carotid Angio Plasty and Stenting

颈动脉血管成形和支架置入术(Carotid angio plasty and stenting,CAS)是包括颈动脉球囊扩张术和支架置入术在内的介入治疗手段。CAS已经被证实是一种治疗颈动脉狭窄和预防卒中的有效方法。尽管CAS是一种微创手术,且手术器材及技术有了很大的改进,但仍然存在许多潜在的并发症,其中围手术期卒中仍是一个令人关注的问题。操作者技术熟练程度、术前病人的筛选、CAS器材的选择(包括栓子保护装置和支架的选择)、颈动脉斑块性质的确定等与围手术期卒中的发生密切相关。充分认识CAS围手术期卒中发生风险因素有利于CAS病例及器材的合理选择,尽可能降低围手术期卒中发生率。本文就CAS围手术期卒中发生风险因素做一个分析。

Carotid angioplasty and stenting（CAS） is an interventional treatment including dilation of aortic sac and stenting.It has been confirmed a modus operandi in carotid artery stenosis and apoplexy precaution.CAS is a mini-operation with fairly improved equipment and skills,but It still has many potential complications,periprocedural apoplexy is one of the problems,it is highly emphasized.Operators＇proficiency,preoperative selection of the patients,selection of the equipment in CAS（embolus protective equipment and stentings） and qualitative ascertainment of carotid artery plaque etc,are all closely correlated with periprocedural apoplexy.So sufficient recognition of periprocedural risk factors of apoplexy in CAS profits the reasonable selections of the patients and equipment and can also decrease the incidence rate.The paper analyze these factors in periprocedural apoplexy.
