Background and Purpose— Stroke is a significant economic, social, and medical problem worldwide. This retrospective follow-up study aimed to review the pattern, types, and case fatality of stroke in Nigeria.

Methods— Records of all stroke patients admitted into Ogun State University Teaching Hospital (OSUTH), Sagamu, from December 1993 to November 2003 were reviewed. Patients were classified into hemorrhage or infarct using the World Health Organization criteria. Information was obtained as to the time of death in those who died and case fatality at 24 hours, 7 days, 30 days, and 6 months recorded. Autopsy records were also reviewed.

Results— A total of 708 stroke patients were reviewed and this constituted 2.4% of all emergency admissions. On clinical grounds, 49% of the patients had cerebral infarction (CI) and 45% had intracerebral hemorrhage (ICH), whereas 6% had subarachnoid hemorrhage. Stroke constituted 1.8% of all deaths at the emergency unit and the case fatality was 9% at 24 hours, 28% at 7 days, 40% at 30 days, and 46% at 6 months.

Conclusion— Stroke constitutes a significant cause of mortality and the need for prompt institution of intensive treatment is emphasized. A changing pattern with an increasing frequency of hemorrhagic stroke in our population is suspected. However, because this was a retrospective study based on clinical examination in a highly selected stroke population, neuroimaging confirmation would be needed for any future prospective hospital or population-based studies.
