What are the differences between Finnish and Dutch patients with subarachnoid hemorrhage?
van Munster et al. (2008) found differences in aneurysm and patient characteristics between Finnish and Dutch patients with subarachnoid hemorrhage. They compared cohorts from 1986 and 2005 and found that the Finnish cohort had a higher proportion of female patients, while the Dutch cohort had a higher proportion of patients aged 65 or older. In addition, the Finnish cohort had a higher rate of aneurysms located in the posterior circulation, while the Dutch cohort had a higher rate of aneurysms located in the anterior circulation. Additionally, the Finnish cohort had a higher rate of aneurysms with a diameter of 10 mm or less, while the Dutch cohort had a higher rate of aneurysms with a diameter of greater than 10 mm. Finally, the Finnish cohort had a higher rate of aneurysm location in the anterior communicating artery, while the Dutch cohort had a higher rate of aneurysm location in the middle cerebral artery.
