Clinical trial of intra-arterial tirofiban during mechanical thrombectomy for acute anterior circulation cerebral infarction
Objective To observe the application effect of intra-arterial tirofiban during mechanical thrombectomy for acute anterior circulation cerebral infarction.Methods The clinical data of patients with acute anterior circulation cerebral infarction were retrospectively analyzed.According to cohort method,they were divided into control group and treatment group.The control group was treated with mechanical thrombectomy,while the treatment group was additionally given intra-arterial therapy with tirofiban 0.25-0.5 mg on the basis of the control group.The perioperative indicators(surgical time,number of thrombectomy,vascular recanalization time,vascular recanalization rate),National Institutes of Health Stroke Scale(NIHSS)score before treatment and at 24 hours and 7 days after treatment,platelet indicators[mean platelet distribution width(PDW),mean platelet volume(MPV),plateletcrit(PCT)],hemorheological indicators[plasma viscosity(PV),low whole blood viscosity(LWBV),high whole blood viscosity(HWBV)],serum indicators[high-sensitivity C-reactive protein(hs-CRP),tumor necrosis factor-α(TNF-α),vascular endothelial growth factor(VEGF)]and clinical efficacy were compared,and the safety of the treatment regimen was assessed.Results There were 92 patients were finally included in this study,including 49 cases in control group and 43 cases in treatment group.The effective rates in treatment group and control group were 75.51％(37 cases/49 cases)and 93.02％(40 cases/43 cases),with significant difference(P＜0.05).The surgical times in treatment group and control group were(93.53±9.86)and(91.59±8.36)min;the vascular recanalization times were(78.46±9.69)and(77.40±10.32)min;the vascular recanalization rates were 93.02％and 83.67％;the NIHSS scores were(10.32±2.90)and(9.59±2.84)points at 24 hours after treatment,all with no significant difference(all P＞0.05).At 7 days after treatment,the NIHSS scores in treatment group and control group were(3.34±1.25)and(4.12±1.48)points;the PDW values were(12.58±1.81)％and(14.15±1.95)％;MPV values were(9.16±1.24)and(11.26±1.86)fL;PCT levels were(0.33±0.05)％and(0.29±0.04)％;PV values were(1.64±0.27)and(1.99±0.24)mPa·s-1;LWBV values were(4.16±0.48)and(5.01±0.49)mPa·s-1;HWBV values were(8.12±0.54)and(9.27±0.68)mPa·s-1;serum hs-CRP levels were(3.57±0.45)and(4.48±0.83)mg·L-1;TNF-α levels were(20.42±4.55)and(27.34±4.95)ng·L-1;VEGF levels were(738.80±52.41)and(664.72±41.68)ng·L-1,all with significant difference(all P＜0.05).Incidence rates of adverse drug reactions in treatment group and control group were 8.16％(4 cases/49 cases)and 4.65％(2 cases/43 cases)respectively,with no significant difference(P＞0.05).Conclusion Intra-arterial tirofiban therapy during thrombectomy for acute anterior circulation cerebral infarction has good neurological function and prognosis,and it may be related to the improvement of platelet function and cerebral tissue blood flow and relief of inflammatory response.
