Background And Objectives:
Randomized trials have demonstrated the benefit of intra-arterial thrombolysis (IAT) for treatment of acute ischemic stroke, if performed within 6 hours of symptom onset.
Methods:
We report our experience with 350 acute stroke patients who were treated with IAT using urokinase at a single center. Predictors of favorable outcome were low National Institute of Health Stroke Scale (NIHSS) at admission (p<0.001), good collaterals (p<0.001) and successful endovascular recanalization (p<0.001). Recanalization rates of more than 75% could be achieved, when additional endovascular techniques such as mechanical fragmentation of the thrombus, thromboaspiration, percutaneous transluminal angioplasty, and implantation of stents were used.
Results And Conclusions:
Predictors of unfavorable outcome were diabetes mellitus (p<0.001) and symptomatic hemorrhages (p<0.001). The latter occurred in 5% of our population. Preliminary results of new techniques including sonothrombolysis, angiojet aspiration, and laser recanalization of thromboembolic occlusions are discussed.
