Answer

Although vasospasm may be treated with intra-arterial pharmaceutical agents, such as verapamil or nicardipine, balloon angioplasty can be used for opening larger vessels (see the images below). The combination of the 2 treatments appears to provide safe and long-lasting therapy for severe, clinically significant vasospasm. [56]

There is significant narrowing of the proximal left ACA, left M1 segment, and left supraclinoid internal carotid artery, indicating vasospasm.

Superimposed road map image demonstrates placement of a wire across the left M1 segment and balloon angioplasty. The left proximal ACA and supraclinoid internal carotid artery (ICA) were also angioplastied, and intra-arterial verapamil was administered. Follow-up image on the right after treatment demonstrates resolution of the left M1 segment and distal ICA, which are now widely patent. Residual narrowing is seen in the left proximal ACA.
