Detection of Vasospasm After Subarachnoid Hemorrhage Using Fully-Autonomous, Robotic TCD


Vasospasm is a pathological, diffuse, and long-lasting narrowing of a vessel lumen that can occur after Subarachnoid Hemorrhage (SAH) and result in Delayed Cerebral Ischemia (DCI). Occurring between 4 and 15 days after initial hemorrhage, it is thought to be a result of pathological signaling secondary to hemorrhagic vessel injury, and requires emergency detection and treatment. Vasospasm has been reported in as many as 70% of SAH patients and results in morbidity and mortality rates of approximately 30%. Detection of vasospasm is critical but difficult as only 20-30% of cases present with notable clinical deficits.1

Transcranial Doppler (TCD) ultrasound is an important tool for detection of cerebral vasospasm after subarachnoid hemorrhage, but is limited by availability of skilled operators.
