ABSTRACT

ABSTRACT Objective: This study was undertaken to determine the positive rate for computed tomography pulmonary angiograms (CTPAs) at the University Hospital of the West Indies (UHWI), to compare the positive rate at the UHWI to that reported in the literature and to compare the rates of positive CTPAs between the genders. Method: Data were obtained from the databases of the Radiology Department of the UHWI. All CTPAs performed to confirm a clinical diagnosis of pulmonary embolism and the results issued during the period January 1st 2013 and December 31st 2013 inclusive were reviewed. Only initial examinations of adequate diagnostic quality were included in the study. Results: Three hundred and thirteenth CTPAs were performed for initial diagnosis of pulmonary embolism. Sixteen examinations were excluded for inadequate diagnostic quality. Two hundred and ninety-seven examinations on 223 females and 74 males were included in the study. The means for age were 49.7 years and 55.1 years, respectively; the difference in the means was significant (p < 0.05). Ninety-four examinations (31.6%) on 22 males (7.4%, mean age 58.4 years) and 72 females (24.2%, mean age 57.5 years) were positive for pulmonary embolism. The difference in the means was not significant (p = 0.8). On Chi-squared test there was no significant difference in the percentage of positive CTPAs between males and females (p = 0.7). Conclusions: The percentage of positive CTPAs at the UHWI is high. There was no significant difference between the genders in the percentage of positive CTPAs or the mean age at which pulmonary emboli were detected.


ABSTRACT Objetivo: Este estudio se llevó a cabo con el propósito de determinar la tasa positiva de las angiografías pulmonares por tomografía computarizada (APTC) en el Hospital Universitario de West Indies (UHWI), comparar la tasa positiva en el UHWI con la que se reporta en la literatura, y comparar las tasas de APTC positivas entre géneros. Método: Se obtuvieron datos de las bases del Departamento de Radiología de UHWI. Se examinaron todas las APTC realizadas para confirmar un diagnóstico clínico de embolia pulmonar y los resultados emitidos durante el período del 1ero de enero de 2013 y 31 de diciembre de 2013 inclusive. En el estudio se incluyeron únicamente exámenes iniciales de calidad diagnóstica adecuada. Resultados: Trecientos trece APTC fueron realizadas para el diagnóstico inicial de embolia pulmonar. Se excluyeron 16 exámenes por poseer una calidad diagnóstica inadecuada. Doscientos noventa y siete exámenes de 223 hembras y 74 varones fueron incluidos en el estudio. Los promedios de edad fueron 49.7 años y 55.1 años respectivamente. La diferencia de los promedios fue significativa (p < 0.05). Noventa y cuatro exámenes (31.6%) de 22 varones (7.4%, edad promedio 58.4 años) y 72 hembras (24.2%, edad promedio 57.5 años) fueron positivos a la embolia pulmonar. La diferencia de los promedios no fue significativa (p = 0.8). En la prueba de Chi-cuadrado no hubo diferencias significativas en el porcentaje de APTC positivas entre varones y hembras (p = 0.7). Conclusiones: El porcentaje de APTC positivas en el UHWI es alto. No hubo diferencias significativas de género en el porcentaje de APTC positivas o la edad promedio a la que se detectaron los émbolos pulmonares.
