Aneurysmal Subarachnoid Hemorrhage in the Elderly over Age 75: A Systematic Review
The number of elderly patients with an aneurysmal subarachnoid hemorrhage (aSAH) has been increasing in aging- or aged societies in many countries. A treatment strategy for the elderly with aSAH has not been established, although many studies have been published emphasizing poor outcome for aSAH. Th...

Summary: | The number of elderly patients with an aneurysmal subarachnoid hemorrhage (aSAH) has been increasing in aging- or aged societies in many countries. A treatment strategy for the elderly with aSAH has not been established, although many studies have been published emphasizing poor outcome for aSAH. The aim of this study was to analyze the factors and treatments affecting outcome in aSAH in the elderly in a systematic review of the literature by investigating patients over age 75. A literature search was done for “elderly aSAH” in PubMed and Embase. Literature with a clear description of treatment measures for aneurysmal occlusion and outcome was selected. Twelve studies, consisted of 816 cases, met the eligibility criteria. Patient characteristics included 83.2% female, 33.8% poor clinical grade on admission, 57.1% Fischer group 3, and 41% internal carotid artery aneurysm. As complications, symptomatic vasospasm was seen in 25.5% of patients, hydrocephalus in 31.1%, and medical complication in 38.4%. Favorable outcome was 35.0% in total, 45.3% for clipping, 36.3% for coiling, and 9.0% for conservative treatment. Several studies by multivariate analysis indicated that poor clinical grade on admission could be a risk factor for neurological outcome and mortality. Advanced age and selection of conservative treatment without aneurysmal occlusion could be a risk factor for mortality. Patients under age 85 with good clinical grade on admission can be candidates for treatment of aneurysm repair. However, treatment for patients over age 85 or with poor clinical grade should be carefully determined. |
