ABSTRACT

Objective To evaluate the mechanism,prevention and prognosis of complications after stent angioplasty in the treatment of carotic artery stenosis. Methods[WT5”BZ] From 1997 to 2003,312 cases of carotid artery stenosis were treated by transluminal stent-assistant angioplasty. Results Procedure-related complication developed in 23 cases including 19 cases of transient mild complications such as transient arrhythmia and hypotension in 10 cases (3.2%) during deploying stent or balloon dilation,transient cerebral ischemia symptoms in 6 cases after balloon dilation,hypotension in 3 cases after the procedure. Severe complications occurred in 4 cases after the procedure,including embolus detachment,stent migration,carotic artery occlusion and fatal cerebral hemorrhage. Conclusion Although stent-assistant angioplasty are effective for treatment of carotid artery stenosis,severe complications could develop.
