  Purpose

To clarify whether amnesia after treatment of anterior communicating aneurysm (ACoA)is related to infarcts caused by occlusion or damage of the perforating artery of the ACoA, we used 3.0-T 3D high resolution MR imaging to identify and localize infarcts in patients with amnesia following treatment of ACoA aneurysm.


Condition
Subarachnoid Hemorrhage
Cerebral Aneurysm
Amnesia

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Cross-Sectional
Target Follow-Up Duration: 6 Years
Official Title: Basal Forebrain Amnesia After Surgery for Anterior Communicating Aneurysm: High Resolution 3-dimensional (3D) Magnetic Resonance (MR) Imaging Findings

Primary Outcome Measures:
  • cerebral infarction identified and localized in the basal forebrain on MR imaging [ Time Frame: within 15 months from the aneurysmal treatment(an expected average 4 months) ] [ Designated as safety issue: No ]

Enrollment: 14
Study Start Date: December 2007
Study Completion Date: July 2013
