Abstract
Objective To observe the clinical efficacy and safety of tirofiban in stent-assisted coil(SAC)embolization for patients with acutely ruptured wide-necked intracranial aneurysms.Methods Patients with acutely ruptured wide-necked intracranial aneurysms who underwent SAC embolization were divided into the control group and the treatment group according to cohort method.The control group was treated with aspirin enteric-coated tablets(300 mg,qd)and clopidogrel bisulfate tablets(300 mg,qd,oral administration)at 2 h before surgery.The treatment group was treated with tirofiban hydrochloride and sodium chloride injection at 10 μg·kg-1 during surgery,which was administrated via intravenous injection at a constant speed within 10 min.Then,the injection rate was adjusted to 0.1 µg·kg-1·min-1 for 12-24 h.The two groups were compared on clinical efficacy,platelet activation function[platelet alpha granule membrane glucoprotein(CD62p)positive rate,platelet adhesion rate and platelet aggregation rate],and perioperative complications.The patients were followed up for 6 months after surgery.The Glasgow Outcome Scale(GOS)scores,recurrence rate and safety were recorded.Results Fifty-three cases and forty-seven cases were included in the treatment group and the control group,respectively.After treatment,the total effective rates of embolization in the treatment group and the control group were 91.49％(43 cases/47 cases)and 81.13％(43 cases/53 cases),without statistically significant difference(P＞0.05).On day 7 after surgery,CD62p positive rates were(56.31±7.41)％and(60.71±7.38)％;platelet adhesion rates were(37.56±3.64)％and(38.04±3.89)％;platelet aggregation rates were(27.03±3.39)％and(30.19±3.63)％.The differences in above indicators between the treatment group and the control group were statistically significant(all P＜0.05).During 6 months of follow-up,the good prognosis rates in the treatment group and the control group were 89.36％and 81.13％;recurrence rates were 4.26％and 9.43％.There were not statistically significant differences in above indicators between the treatment group and the control group(all P＞0.05).The perioperative complications in the two groups mainly included rerupture and bleeding of arterial aneurysms,subdermal ecchymosis,gingival bleeding,thrombotic events,etc.The total incidences of complications in the treatment group and the control group were 10.64％and 28.30％,with statistically significant difference(P＜0.05).Conclusion Tirofiban hydrochloride and sodium chloride injection can effectively reduce the incidence of thrombotic events in patients with acutely ruptured wide-necked intracranial aneurysms during perioperative period of SC A embolization,and improve platelet activation function.关键词
