摘要

“Subarachnoid Hemorrhage is non-traumatic nasty bleeding into the subarachnoid area, the territory between the arachnoid and the piamater of the central nervous system showing prompt developing signs of neurological sequelae”. It is one among the neurological emergencies which is a very distressing cerebrovascular disease with complicated mechanisms that risks brain perfusion and its function, having higher morbidity and mortality rates. Its mortality rate is still ranged between 8.3% and 66.7%, with noticeable regional variations, beside recent advances in treatment approaches. The incidence of SAH among the population of 2 - 22.5/100,000 was reported with a minimum of 60% of aneurysm ruptures occurring amid ages of 40 and 60 years with 3:2 male:female ratio. The rupture risks for unruptured aneurysms are increased by the issues like present smokers, larger size of aneurysm, and amid young population. The surgical treatment decision should be contemplated upon factors such as aneurysm’s size, aneurysm’s location, patient’s illness history, and surgeon’s operative experiences. Latest technical progresses in imaging techniques, increased consideration of illness history, more awareness of incidences of aneurysms and use of micro neurosurgery, have raised the chance for detection of subarachnoid hemorrhage (SAH) and possible better outcomes with surgical management. Factors that may affect outcome include age, size and site of aneurysm, interval between ictus and surgery, CT Fisher Grade & Hunt and Hess Grading earlier to surgery, & Glasgow Coma Scale at the while of discharge. The studies here support the wide spread concept that surgical clipping of SAH for Hunt and Hess Grade 4, 5 SAH, which is also considered as poor Grade SAH stipulates an effective treatment if done earlier provides better outcome.
