| ABSTRACT |
|
A case of large aneurysm of azygos anterior cerebral artery(Azygos ACA) is reported. This 52-year-old male patient became unconscious suddenly on working. The CT scan demonstrated small amount of hemorrhage in the interhemispheric fissure and basal cistern and huge intraventricular hematoma with marked dilatation of all ventricles. Emergency external ventricular drainage was done and his consciousness recovered to the level of possible spontaneous eye opening. 4-vessels angiography done a month later revealed a large revealed a large fusiform aneurysm at the bifurcation of distal end of azygos ACA. Authors preferred interhemispheric approach and clipped the aneurysmal neck uneventfully. Despite the successful clipping of the aneurysm confirmed by postoperative angiography, preoperative mutism, spastic weakness of lower extremities and urinary incontinence didn't recovered. This case suggests that preoperative neurological status is no less critical to the postoperative outcome than surgical technique. This is the first case of large aneurysm at this site so far as we know. |
