Abstract
Angioplasty of the proximal portions of major cerebral arteries at the base of the brain has shown promise as a therapy for symptomatic vasospasm after subarachnoid hemorrhage. The blind-ended, single-lumen balloon-dilatation catheter most widely used to date lacks steerability, limiting its application to unbranched stems and single branches at bi- or trifurcation points. To extend the capabilities of cerebral angioplasty, we describe two modifications of the basic technique that have allowed increased selectivity and successful angioplasty of multiple branches, both proximal and distal, involved by vasospasm. Of four patients treated, three showed early improvement in their clinical condition, likely attributable to the angioplasty procedure. Our modifications to the basic angioplasty technique enhanced its success. Further refinement of this technique in the treatment of vasospasm will make it safer in treating this serious and widespread disorder.
