The balloon disruption was performed with a low-profile microballoon catheter. The microballoon was inflated in the distal carotid artery and then deflated and advanced just distal to the occlusion site in the MCA. Thereafter, an intra-arterial thrombolysis of the MCA was applied. The maximum time from the onset of symptoms to the start of treatment and maximum dosage of urokinase was 6 hours and 600,000 U. The outcome was classified as good for a modified Rankin Scale (mRS) score of 0 or 1, moderate for a score of 2 or 3, and poor for a score of 4 or 5.RESULTS: Complete recanalization was achieved in 5 patients and partial recanalization in 3. Three patients recovered to an mRS score of 0 or 1; 3, to scores of 2 or 3; and 1, to a score of 4. No patients died. There was no major intracerebral hemorrhage.CONCLUSIONS: 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.
