Safety and efficacy of balloon angioplasty of the anterior cerebral artery for vasospasm treatment after subarachnoid hemorrhage

Balloon angioplasty is often performed for symptomatic vasospasm following aneurysmal subarachnoid hemorrhage. Angioplasty of the anterior cerebral artery (ACA), however, is perceived to be a challenging endeavor and not routinely performed due to technical and safety concerns. Here, we evaluate the safety and efficacy of balloon angioplasty of the anterior cerebral artery for vasospasm treatment. Patients with vasospasm following subarachnoid hemorrhage who underwent balloon angioplasty at our institution between 2011 and 2016 were retrospectively reviewed. All ACA angioplasty segments were analyzed for pre- and post-angioplasty radiographic measurements. The degree of vasospasm was categorized as mild ( 50%), and relative change in caliber was measured following treatment. Clinical outcomes following treatment were also assessed. Among 17 patients, 82 total vessel segments and 35 ACA segments were treated with balloon angioplasty. Following angioplasty, 94% of segmen...
