Abstract
Objective: Subarachnoid hemorrhage (SAH) often results in devastating neurological deficits requiring hospitalization and loss of independence. This is often a difficult time for patients and their families who are struggling to cope with this sudden illness. Current treatment options include surgical clipping of the aneurysm or endovascular obliteration using Guglielmi detachable coils. Our purpose in writing this paper was to review the factors that determine the choice of treatment. In addition to this we wanted to study the benefits of surgical clipping for ruptured aneurysms over endovascular coiling. Material and Methods: We studied - retrospectively - 450 cases of ruptured cerebral aneurysms admitted to our institution from 1997 to 2003. Out of these, 324 were subjected to surgical clipping and 126 to endovascular techniques. The outcome was studied using the Glasgow Outcome Score (GOS). Results: Of the 324 cases of surgical clipping 222 had a good recovery, 38 had moderate disability, 15 had severe disability, 13 became vegetative and 36 patients died. In the endovascular group 34 had a good recovery, 22 had moderate disability, 18 had severe disability, 15 became vegetative and 37 patients died. Grade to Outcome was compared for both forms of treatment. In our series clipping for ruptured aneurysm was preferred to coiling in fusiform-shaped aneurysms, large or giant aneurysms, MCA aneurysms, blister aneurysms, complex configurations, partially thrombosed aneurysms and aneurysms associated with cerebral hemorrhage. Coiling was performed for basilar tip and trunk aneurysms, high anterior communicating artery aneurysms, patients in subacute stages of subarachnoid hemorrhage, and those with associated medical complications. Conclusion: Based on this study we were able to formulate a few definite indications for clipping, even in the times of advanced endovascular techniques. In addition we could also prove the benefits of surgical clipping over the endovascular technique in severe subarachnoid hemorrhage.
