Endovascular Ultraviolet Laser-Facilitated Reversal of Vasospasm Induced by Subarachnoid Hemorrhage in Canines

Background: Because treatments for cerebral arterial spasm—a delayed consequence of subarachnoid hemorrhage (SAH)—are clinically inconsistent, we describe here a new method for reversal of arterial spasm, possibly extensible to nitric oxide (NO)-sensitive microvasculature.
