Clinical Study Of Stent Placement In The Treatment Of Symptomatic Intracranial Artery Stenosis

Objective：To observe the clinical efficacy in the short term and complicationsof stent placement in the treatment of symptomatic intracranial arterystenosis,and analysis the short-term therapeutic effect and safety.Methods:From September2012-September2014, select in43patients whohas a clear diagnosis of intracranial artery stenosis with DSAexamination.the main clinical manifestations are frequently transientdizziness, ataxia,amaurosis,blurred vision,speech impairment,aphasia,limb movement disorder,transient loss of consciousness.Therewere23males,female20cases,mean age58.14±6.53years old,thepatients were grouped according to age(group A≤50years old; groupB50-60years old; group C>60years old),8cases in A group,17casesin B group,18cases in C group.The morphology of intracranial arterystenosis according to Mori classification,including29cases of type A,14cases of type B.According to the degree of stenosis type,The severestenosis (70%-89%) in34cases, very severe stenosis (more than90%)in9cases. The definition of the degree of restenosis for luminal stenosis rate is greater than or equal to50%.From3days before theoperation,oral aspirin (300mg,1/d)and clopidogrel (75mg,1/d). Operationmode via femoral artery puncture, for endovascular stent implantationoperation,postoperative patients given a positive drug treatment, Analysisof arterial morphology, degree of stenosis, operation effect andcomplications.Result:43cases of operation are all successful, The average rate oftenosis from preoperative80.81%±6.72%to postoperative15.12%±6.02%; no complications occurred,8cases of postoperative complications,According to Mori classification,2cases in type A,6cases in type B;According to the stenosis,4cases in severe stenosis and4cases in verysevere stenosis. According to age, A group has2cases occurredrestenosis and B group has1case occurred restenosis at6months afteroperation.Conclusion:1)Stent implantation in the treatment of symptomatic intracranialartery stenosis with better security and the short term clinicaleffect.2)The probability of complications after operation has a certaineffect with the narrow shape and the degree of stenosis of intracranialartery stenosis,and the age of the patients also have a certain effect onthe incidence of restenosis.
