Abstract:
Objective To evaluate the safety and efficacy of intra-arterial thrombolysis in patients with acute cerebral ischemic stroke.Methods Twenty-one patients with acute internal carotid circulation infraction(internal carotid 3,MCA 12,ACA 5,lenticulostriate in 1) were treated with intra-arterial thrombolysis of recombinant tissue plasminogen activator(rt-PA) which was performed within 2-6 hours of symptom onset.Recanalization was observed during the operation.Intracerebral hemorrhage(ICH) was monitored immediately and 24 h after the treatment by CT or MRI scanning.Chinese stroke scale was used to evaluate the recovery of neurological functions pre-operatively and 30 d after the treatment.Results All the 21 patients were 100% success in receiving intra-arterial thrombolysis technique and revealed 16 having the degree of recanalization of 2 to 3 grade as regards to TMI,16 patients' degree of recanalization reached 2 to 3 grade according to TMI;5 patients showed 1 to 2 grade.Symptomatic ICH was observed in 3 patients,with two dead.Arterial dissection was found in one patient.Thirty days after the operation,17 patients' cerebral function reduced over 50 percent;2 less than 50 percent;and 2 died.The patients achieved 2 to 3 grade of recanalization were obviously getting better than those achieving 0 to 1 grade.Conclusions It is adapt to have intra-arterial thrombolysis with six hours from onset;but still have the danger of severe ICH.The treatment should be started as early as possible.
