Neuroendovascular management of vasospasm following aneurysmal subarachnoid hemorrhage.

Cerebral vasospasm continues to be the leading treatable cause of death and disability in patients with subarachnoid hemorrhage. Transluminal balloon angioplasty has been considered a safe and effective treatment for cerebral vasospasm resistant to maximal medical treatment. However, it should be performed in a timely manner, any delays could potentially increase the risk of hemorrhagic infarct. Angioplasty in the affected territory may be of benefit in improving not only the angiographic appearance but also the ultimate outcome for the patient, if performed in a timely fashion.
