Intracranial aneurysms are a common cerebrovascular disease and the leading cause of subarachnoid hemorrhage.With the development of endovascular interventional techniques,more and more patients are being treated with stents or flow diverter.For this reason,antiplatelet therapy has become a routinely administered drug before and after endovascular interventions.This review intends to summarize the common antiplatelet drug classes,drug mechanisms,platelet function tests and clinical applications.

Objective To investigate the safety and effectiveness of Solitaire FR stent mechanical thrombectomy combined with 5F Navien catheter aspiration technique for the treatment of acute middle cerebral artery occlusion.Methods From February 2016 to May 2016,the case data of 11 consecutive patients with acute middle cerebral artery occlusion treated with Solitaire FR stent mechanical thrombectomy combined with 5F Navien catheter aspiration technique at the Department of Neurosurgery,Xuanwu Hospital,Capital Medical University were enrolled retrospectively.The age,gender,National Institutes of Health Stroke Scale (NIHSS) score on admission,thrombolysis in cerebral infarction (TICI) grade,operation-related complications,NIHSS score at 24 h after operation,and modified Rankin Scale (mRS) score at day 90 after operation were documented.The relevant data differences before and after treatment were analyzed with the SPSS software.Results Among the 11 patients with acute middle cerebral artery occlusion,7 were men and 4 were women,the age ranged from 44 to 78 years,and the mean age was 66 ± 11 years.The preoperative and postoperative NIHSS scores were 18 ± 3 and 8 ±4 respectively.There was significant difference before and after treatment (t =5.327,P ＜ 0.01).The recanalization of occluded middle cerebral artery achieved successfully.The follow-up at day 90 after operation,the good prognosis of the patients (mRS 0-2) was in 7 cases.No complications associated with severe M1 segment catheter operation occurred.Conclusion The preliminary experience showed,Solitaire FR stent mechanical thrombectomy combined with 5F Navien catheter aspiration technique for the treatment of acute middle cerebral artery occlusion was a safe and effective endovascular mechanical thrombectomy method.
