采用尿激酶（ＵＫ）对１３例急性脑梗塞病人做溶栓治疗。静脉溶栓１２例，动脉溶栓１例。并在治疗前后对临床、ＣＴ、脑血管造影（ＤＳＡ）进行分析。有效８例（６１．５２％）、无效３例（２３．０７％）、恶化２例（１５．３８％），无死亡。１例动脉溶栓后无症状性脑实质出血。尿激酶超早期溶栓有较好的临床效果及安全性，溶栓的同时应该加强脑保护 Thrombolytic therapy was performed on 13 patients with acute cerebral infarction using urokinase (UK). Intravenous thrombolysis in 12 cases, arterial thrombolysis in 1 case. And before and after treatment of clinical, CT, cerebral angiography (DSA) analysis. 8 cases were effective (61.52%), 3 cases (23.07%) were ineffective and 2 cases (15.38%) were exacerbated without death. One patient had asymptomatic cerebral parenchymal hemorrhage after thrombolysis. Urokinase ultra-early thrombolysis has a better clinical effect and safety, thrombolysis should also strengthen the protection of the brain
