ABSTRACT
OBJECTIVE: To examine the pattern of stroke subtypes found on Computed Tomography (CT), Magnetic Resonance Imaging (MRI) at the University Hospital of the West Indies (UHWI), Kingston, Jamaica. METHOD: A retrospective review was conducted for all patients diagnosed with stroke and who were subjected to CT or MRI evaluation at UHWI between January 2001 and December 2004. Data were collected for patient age and gender and type of stroke. RESULTS: Four hundred and thirty-three patients were identified and classified as having cerebral infarct, intra-parenchymal haemorrhage or subarachnoid haemorrhage. There were 414 patients who had CT scans and 19 had MRI scans. Within and across genders, over 80% suffered infarcts with no significant statistical difference between male and female patients. Subarachnoid haemorrhage was the least frequent subtype and occurred in younger patients. CONCLUSION: The pattern of stroke subtypes seen in this population was similar to that of Australian and European cohorts of patients but differed from that reported in Asians. Ischaemic infarct was the most frequent stroke subtype followed by intra- parenchymal haemorrhage and subarachnoid haemorrhage. There was no gender predilection for any specific type of stroke.
RESUMEN
OBJETIVO: Examinar el patrón de los subtipos de accidente cerebrovascular encontrados en las imágenes de TAC y MRI en el Hospital Universitario de West Indies (HUWI), Kingston, Jamaica. MÉTODO: Se realizó un examen retrospectivo de todos los pacientes con diagnóstico de accidente cerebrovascular, sometidos a evaluación mediante TAC o MRI, entre enero 2001 y diciembre 2004. Los datos fueron recogidos teniendo en cuenta la edad y el género del paciente, así como el tipo de accidente. RESULTADOS: Cuatrocientos treinta y tres (433) pacientes fueron identificados y clasificados como pacientes con un infarto cerebral, hemorragia intraparenquimal o hemorragia subaracnoidea (HSA). Hubo 414 pacientes examinados con TAC y 19 con MRI. Dentro de ellos, ambos géneros incluidos, más del 80% sufrió infartos sin que hubiese diferencias estadísticas significativas entre hombres y mujeres. La hemorragia subaracnoidea fue el tipo menos frecuente, y se produjo en pacientes jóvenes. CONCLUSIÓN: El patrón de subtipos de accidente cerebrovascular en esta población fue similar al de cohortes de pacientes australianos y europeos, pero diferente al reportado para los asiáticos. El infarto isquémico fue el subtipo de accidente cerebrovascular más frecuente, seguido por la hemorragia intraparenquimal y la hemorragia subaracnoidea. No hubo preferencia de géneros en relación con ninguno de los tipos específicos de accidente cerebrovascular.
