Relationship between decreased cerebral blood flow and amnesia after microsurgery for anterior communicating artery aneurysm.

ABSTRACT:

Objective

Postoperative amnesia after surgery for anterior communicating artery aneurysm might be associated with the damage of the basal forebrain. Our purpose was to verify whether decreased regional cerebral blood flow (rCBF) in basal forebrain could be related to the degree of postoperative amnesia.

Methods

Regional voxel rCBF data analyzed using three-dimensional stereotactic surface projection on ¹²³I-IMP-SPECT were compared between ten patients with postoperative amnesia and 13 normal subjects. The Severity (average Z score of the voxels with a Z score that exceeds a threshold value of 2) was calculated. The cerebral lobes with rCBF exhibiting Severity > 2 in all patients were identified. In these lobes, we then examined whether there was a gyrus exhibiting
