Balloon catheter disruption of thrombus in conjunction with thrombolysis for the treatment of acute middle cerebral artery occlusion / 介入放射学杂志

ABSTRACT

Objective To assess the feasibility, safety, and efficacy of balloon disruption of thrombus by using a deflated balloon catheter combined with intraarterial thrombolysis for the treatment of acute middle cerebral artery(MCA) occlusion. Methods Five consecutive patients with acute MCA occlusion underwent balloon disruption combined with intra-arterial thrombolysis. The microballoon was inflated in the distal carotid artery and then deflated and advanced just distal to the occlusion site in the MCA. Thereafter, intra-arterial thrombolysis of the MCA was applied and the maximum dosage of urokinase was 500,000 U. Results Complete recanalization was achieved in 3 patients and partial recanalization in 2. All patients got favourable clinical outcome. There was no major intracerebral hemorrhage. Conclusion The penetration of the MCA with a deflated balloon catheter combined with an intra-arterial thrombolysis may be a safe and effective treatment for acute ischemic stroke.
