Saccular aneurysms of the distal anterior cerebral artery

Abstract

✓ A series of 13 patients with saccular aneurysms of the distal anterior cerebral artery, operated on by the same surgeon with microtechniques, is reviewed. The incidence of aneurysms in this location was 3.4%, the median age of the patients 44 years, and the median time from most recent hemorrhage to surgery 13 days. There were five cases of multiple aneurysms. No operative mortality occurred; the operative morbidity was 15%. Because of their multiplicity, characteristic broad base, and the small subarachnoid space in the interhemispheric fissure, these aneurysms are judged technically difficult.
