What factors affect the outcomes of older patients after aneurysmal subarachnoid hemorrhage?
Several factors can affect the outcomes of older patients after aneurysmal subarachnoid hemorrhage, including the presence of medical complications, hospital-related factors such as case volume, and endovascular services. Studies have found that older patients tend to have poorer outcomes than younger patients, with higher mortality rates. Factors such as global cerebral edema, the size of the aneurysm, and the presence of warning signs have also been associated with poorer outcomes. Additionally, older patients may have more difficulty accessing or tolerating endovascular treatment, which can lead to a worse outcome.
