Vasospasm Monitored by Transcranial Doppler

Abstract

Vasospasm almost always occurs following rupture of an aneurysm in the Circle of
Willis. Spasm is less likely in peripherally located aneurysms, for example those complicating
bacterial endocarditis.
For a day or two spasm is often absent or minimal. If the patient’s condition is good,
many surgeons will proceed at this time either with surgery or endovascular placement of coils
in the aneurysm to make it undergo thrombosis.
