Objective: This study evaluated the prognostic factors that influence the surgical outcomes of elderly patients older than 65 years old with an aneurysmal subarachnoid hemorrhage.
Methods: Ninety-two patients older than 65 years old, who were operated in our hospital between 1998 and 2005, were reviewed retrospectively. The clinical outcomes were evaluated using the modified Rankin Scale three months after surgery.
Results: The preoperative neurological status, such as the Hunt-Hess grade (p<0.001), World Federation of Neurological Surgeons (WFNS) grade (p<0.001), and the Fisher grade (p=0.001), was significantly associated with the surgical outcomes in this series. The vasospasm (0.016) and ventriculostomy (0.039) are factors influencing the surgical outcomes. However, the other factors including hypertension (0.831), smoking (0.228), accompanying disorder (0.706), size of aneurysms (0.177), location of aneurysms (0.755), shunt operation (0.356), and timing of surgery (0.194) had no influence on the surgical outcome.
Conclusion: In elderly patients with intracranial aneurysms, the preoperative neurological status, vasospasm, and ventriculostomy are the most significant prognostic factors.
