FIG 2. Case 4. This patient with right hemiparesis was treated with intra-arterial nimodipine for symptomatic cerebral vasospasm following SAH. This patient had moderate vasospasm of tICA, ACA and MCA on the left side.

A, Lateral angiogram of the left internal carotid artery shows vasospasm involving also the distal cerebral branches (arrows).

B, Lateral angiogram of the left internal carotid artery obtained after the intra-arterial injection of nimodipine 2 mg shows a slight increase in the size of the distal arteries (arrows) and the internal carotid system. Despite the poor angiographic results, the patient’s condition improved significantly within 12 hours, and no recurrence of symptoms was observed.
