Abstract
|
|
|
We present our recent experience f two rare rare cases of ruptured aneurysm of the azygos anterior cerebral together with a review of the literature On admission. the patients were in clinical Grade 4 of Hunt and Hess classification Cerebral
angiograms
showed a giant saccular aneurysm (25×10×10 mm in size0 on the distal bifurcation portion of the azygos anterior cerebral artery in one patient. and a medium sized saccular aneurysm (7×9 mm in size) on the proximal portion of azygos anterior
cerebral
artery in the other patient Both the patients underwent a successful. direct clipping of the aneurysmal neck through an interhemispheric and left parietal approach. respectively. One month later after the operations one patient showed mutism and
spastic
paraparesis and the other remained ina drowsy mental status with lett side hemiparesis. The pre-operative neurologic status and further neurologic deficits attributed to cerebral vasospasm are thought to be the most important prognostic factors
in
deciding the post-operative outcome in these patients.
