Abstract:
Objective To study the clinical efficacy of intra-arterial thrombolysis with recombinant tissue plasminogen activator (rt-PA) for the treatment of ischemic cerebrovascular disease caused by cerebral thrombosis. Methods A total of 245 patients accepted by our hospital during May 2013 and July 2015 were divided into the observation group (n=148) and the control group (n=97). All patients were given conventional process for controling blood pressure and blood lipids. Patients in observation group received intra-arterial thrombolysis with rt-PA, while patients in control group accepted conventional treatment. At the time of admission, the demographic characteristic, vascular influencing factors, baseline clinical findings, laboratory findings and neurological deficits were collected. The improvement of neurological function was evaluated by the modified Rankin scale 3 months after treatment. The levels of fibrinogen (FIB), D-Dimer, activated partial thromboplastin time (APTT) and thrombin time (PT) were measured before and 24 h after the treatment. Results There were no significant differences in demographic characteristic and general clinical data between the two groups ( P>0.05). The proportion of patients with improved neurological function was significantly higher in observation group than that of the control group (83.11％vs. 53.61％, P<0.05). There were no significant difference in coagulation index and fibrinolysis index before treatment between the two groups (P>0.05). Twenty-four hours after the treatment, the levels of FIB, D-Dimer, APTT and PT were significantly improved in the observation group compared with those before treatment. The level of FIB was significantly decreased, D-Dimer was significantly increased, APTT and PT were significantly prolonged in observation group compared with those of control group (P<0.05). Conclusion The rt-PA can effectively dissolve thrombosis and correct the coagulation system and fibrinolytic system.
