Description
Takahiro Morita and colleagues report rescue use of clazosentan for brain vessel spasm after bleeding in a 2026 case. A 61-year-old man bled from a ruptured fistula in the front skull base. After surgical closure, preventive drug care failed to stop severe spasm in both front and middle brain arteries by day 10, with growing drowsiness.
Direct artery drug doses helped only briefly. Clazosentan then ran for 4 days as rescue care, and vessel imaging showed marked widening, most of all in small far vessels. Fluid build-up was handled with diuretics without breathing decline. No brain infarction arose, and the patient transferred out with a near-normal function score.
