FIG 3. Case 12. Patient presenting with left hemiparesis and diffuse and severe vasospasm. After an intra-arterial injection of 3 mg of nimodipine into both carotid arteries and the basilar artery, angiographic and clinical results were poor. A second session with injection of 5 mg of nimodipine into the same vessels achieved good angiographic results and clinical improvement.

A, This angiogram obtained before the intra-arterial injection of nimodipine shows a moderate vasospasm of the left vertebral artery. (Vasospasm was severe in the other vessels, not shown.)

B, After nimodipine therapy, this left vertebral artery angiogram shows increased size of the basilar artery. Despite these results, the patient later died from cardiopulmonary complications.
