From journal article: the safety and efficacy of noncompliant balloon angioplasty was reported for treatment of subarachnoid haemorrhage-induced cerebral vasospasm at three major academic institutions in the united states.Vessels treated include the internal carotid artery (ica), middle cerebral artery (mca), anterior cerebral artery (aca), basilar artery (ba), posterior cerebral artery (pca), posterior inferior cerebellar artery (pica) and vertebral artery (va).Aneurysmal subarachnoid haemorrhage (sah) was present in 50 patients, whereas the sah was from an unknown source in 2 patients.The sprinter legend balloon was the most commonly used balloon during the angioplasty procedures.During the procedure, the balloon was inflated to nominal pressure at a rate of 2-4 atm per minute using a manual insufflation device and repositioned after deflation as needed.All procedures used noncompliant balloons.The mca and intracranial ica were the most commonly treated vessels.No procedure related complications were reported.There was improvement in angiographic vasospasm in 97% of cases without any associated procedural morbidity or mortality.Outcome included delayed cerebral ischemia.Functional outcome after discharge from icu included patient death.One patient presented with a ruptured anterior choroidal internal carotid artery aneurysm, which was subsequently treated with endovascular embolization.The procedure was complicated by thrombosis of the right anterior cerebral and middle cerebral arteries, which was treated with medical thrombolysis and mechanical thrombectomy.The patient developed significant cerebral edema of the right hemisphere and underwent hemicraniectomy.On hospital day 4, the patient had a decline in mental status and was taken for digital subtraction angiography.Angiographic vasospasm was found in the right m1 segment of the middle cerebral artery and right a1 segment of the anterior cerebral artery.Angioplasty was performed with a sprinter legend balloon (1.5 mm x 10 mm) in the right m1 segment, and intra-arterial verapamil was infused in both right m1 and a1 segments.Vasospasm of the right m1 segment improved from severe to moderate.The patient¿s clinical condition remained poor, and the patient died on hospital day 10.
