ObjectiveTo study whether intravenous thrombolysis combined with interventional thrombectomy can effectively improve the prognosis of patients with acute cerebral infarction.

MethodsThirty-three patients with acute cerebral infarction were selected and randomly divided into intravenous thrombolysis group (group A, 17 cases) and intravenous thrombolysis combined with interventional thrombectomy group (group B, 16 cases) according to different treatment methods.Relevant clinical data of all patients before and after treatment, including gender, age, smoking history, blood pressure, blood sugar level, total cholesterol level, waiting time for thrombolytic therapy and so on were collected.The risk factors of acute cerebral infarction and the changes of the National Institutes of Health stroke scale (NIHSS) score and Barthel index score between before and after treatment were analyzed, and the prognosis and living ability of patients were compared.

ResultsThe levels of blood pressure, blood glucose, total cholesterol, plasma D dimer, fibrinogen degradation products and smoking history were positively correlated with the NIHSS score after admission to the hospital (P < 0.05 to P < 0.01).Pearson correlation analysis found that the patient's blood pressure and blood glucose level were the key factors affecting the occurrence of acute cerebral infarction(r=0.768, 0.559).The treatment effect and prognosis of patients with acute cerebral infarction were closely related to the waiting time and treatment methods for treatment.The changes of NIHSS score of patients in group A at 7 days after treatment, and at 24 hours after treatment and 7 days after treatment in group B were tightly related to the length of waiting time for treatment, i.e.the improvement of NIHSS score was more obvious with shorter waiting time for treatment (P < 0.05).There was no significant correlation between the changes of NIHSS score of patients in group A and the waiting time for treatment at 24 h after treatment (P>0.05), while which in group B had different degrees of improvement.At the same time, the improvement of the patient's Barthel score was more obvious with shorter the waiting time for thrombolysis (P < 0.01).At 24 h and 7 d after receiving treatment, the improvement of NIHSS score and Barthel score of patients in group B was more obvious than that in group A(P < 0.01).

ConclusionsThe better the recovery of patients with acute cerebral infarction can be obtained with shorter time from onset to thrombectomy.Intravenous thrombolysis combined with interventional thrombectomy has better recovery effect for patients with acute cerebral infarction than intravenous thrombectomy alone.
