Serial angiograms, CT scans and clinical courses of 40 patients with vasospasm are analyzed. Angiographic vasospasm has a tendency to develop on arteries adjacent to ruptured aneurysms. The configuration of spasm changes from smooth narrowing into irregular narrowing. The former is observed after the 5th day and the latter after the 9th day of the rupture. Resolution of spasm follows irregular narrowing.
Angiographic vasospasm, neurological symptoms, and low density areas on CT scan develops at intervals of 2 to 3 days.
Optimal timing for direct aneurysmal surgery is discussed in relation to the time course of vasospasm.
