vasospasms
Arterial squeezing episodes
Vasospasms are sudden, temporary contractions of blood vessel walls that reduce blood flow.
They occur most dangerously in coronary arteries, where they can trigger chest pain or heart attacks, and in the brain following hemorrhage.
The singular vasospasm describes a single episode: The patient experienced a vasospasm after the aneurysm ruptured.
