Symptomatic vasospasm in elderly patients with aneurysmal subarachnoid hemorrhage: Comparison with nonelderly patients

Abstract

Objective: To clarify the influence of age on the occurrence of symptomatic vasospasm (SVS), we retrospectively compared 34 elderly (over 70 years) and 71 nonelderly patients with aneurysmal subarachnoid hemorrhage (SAH). Methods: Between 2008 and 2010, at our hospital 105 patients (Hunt and Kosnik grades I-IV) underwent aneurysm surgery within 72 h of the insult. They were divided into four groups based on their age (younger/older than 70 years) and treatment (aneurysmal clipping or coiling). In all patients, we used the same protocol, which included the delivery of intrathecal urokinase and intravenous fasudil chloride; in patients with angiographic evidence of vasospasm, we also injected fasudil chloride intra-arterially. Results: Among the elderly patients, 4.3% of those treated by clipping and 9.1% of those treated by coiling experienced SVS; the comparative incidence in younger patients was 6.5% and 4.0%, respectively. The differences were not statistically significant (p = 0.40). The ratio of ventriculo peritoneal (VP) shunts was higher in the elderly patients (p = 0.00007). The incidence of favorable treatment outcomes was significantly lower in elderly patients (p = 0.00004). Conclusion: Under our treatment protocol, patient age did not affect the incidence of SVS. Our protocol may be effective for the prevention of SVS after aneurysmal SAH regardless of patient age. © 2013 Springer-Verlag Wien.
