title: Angioplasty for the treatment of symptomatic vasospasm following subarachnoid hemorrhage.
abstract: Angioplasty of narrowed cerebral arteries was performed in 10 patients who became symptomatic from vasospasm following subarachnoid hemorrhage. This procedure was accomplished with a microballoon catheter via percutaneous transfemoral insertion. Patients were selected for treatment if they had delayed neurological deficits due to vasospasm which were not responsive to hypervolemic hypertensive therapy. Eight patients (80%) showed sustained improvement in neurological function following the procedure. In two patients transcranial Doppler ultrasound recordings were obtained which revealed decreased mean blood flow velocities following angioplasty. Two patients died, one from an aneurysmal rebleed, and one secondary to diffuse vasospasm. There was one case of delayed stroke 6 weeks following the procedure. The overall results of this series indicate that in selected cases percutaneous balloon angioplasty can offer marked improvement to patients with ischemic deficits due to vasospasm following subarachnoid hemorrhage.
