Background:
Aneurysmal subarachnoid hemorrhage (A-SAH), despite improvement in surgical and medical treatments, is still a serious disease with high fatality and morbidity rates. Despite the huge advances in neurosurgical management of the disease, there has not been a proportional improvement in outcome of this condition.
Purpose:
We studied various factors which can influence the final outcome and these included: World federation of neurosurgical societies (WFNS), Hunt & Hess (H&H) and Fisher grade, size of aneurysm, intra operative rupture (IOR), temporary clipping (TC) - and correlate their individual impact in final outcome.
Methods:
We studied 100 patients of aneurysmal subarachnoid hemorrhage prospectively all of whom were operated upon .Post operative course was followed and final outcome studied.
Results:
Pre operatively, higher WFNS and H&H grades had a worse outcome. This correlation was not found for Fisher grade. Nonetheless, presence of IVH(Fisher grade 4) acted as an independent risk factor for poor outcome.
Conclusion:
Diabetes and smoking led to a worse outcome in contrast to hypertension . IOR led to poor outcome while temporary clipping did not.
