Abstract

The authors evaluated the diagnostic yield of chest multidetector computed tomography MDCT in acute pulmonary embolism PE and the proportion of other clinically relevant findings in a large cohort of consecutive inpatients and patients referred from the emergency department outpatientsA total of 327 radiological reports of chest MDCT scans performed for suspected acute PE in 327 patients 158 men 169 women mean age 69 years standard deviation 1733 years 233 inpatients 94 outpatients were retrospectively evaluated and classified into four categories 1 positive for PE 2 negative for PE but positive for other findings requiring specific and immediate intervention 3 completely negative or positive for findings with a potential for significant morbidity requiring specific action on followup 4 indeterminate The distribution of findings by categories among the entire population and inpatients and outpatients separately was calculated chisquare test α=005In the entire population the diagnostic yield ie proportion of cases classified as category 1 was 202 66/327 Proportions of cases classified as categories 2 3 and 4 were 275 90/327 443 145/327 and 79 26/327 respectively No statistically significant difference was found between inpatients and outpatients p=0193Scopo del nostro lavoro è stato valutare la resa diagnostica della tomografia computerizzata multidetettore TCMD del torace nell’embolia polmonare acuta EP e la proporzione di altri reperti clinicamente rilevanti in un’ampia coorte di pazienti consecutivi sia ricoverati che provenienti dal Pronto Soccorso PSSono stati retrospettivamente considerati 327 referti radiologici di TCMD del torace eseguite per sospetta EP acuta in 327 pazienti 158 M 169 F età media 69 anni deviazione standard DS 1733 anni 233 ricoverati 94 provenienti dal PS Gli esami sono stati classificati in quattro categorie 1 positivi per EP 2 negativi per EP ma positivi per altri reperti richiedenti intervento specifico ed immediato 3 negativi del tutto o positivi per reperti con potenziale significato di morbilità richiedenti specifico intervento al followup 4 indeterminati È stata calcolata la distribuzione dei reperti in categorie nell’intera popolazione e separatamente nei pazienti ricoverati e nei pazienti provenienti dal PS test Chiquadrato α=005Nell’intera popolazione la resa diagnostica vale a dire proporzione di casi classificati in categoria 1 è stata del 202 66/327 Le proporzioni di casi classificati in categoria 2 3 e 4 sono state del 275 90/327 443 145/327 e 79 26/327 rispettivamente Non sono state rilevate differenze statisticamente significative tra i pazienti ricoverati e quelli provenienti dal PS p=0193Nei pazienti con sospetta EP acuta la TCMD del torace evidenzia condizioni richiedenti un intervento specifico ed immediato vale a dire categorie 1 e 2 in quasi il 50 dei casi senza differenze tra i pazienti ricoverati e quelli provenienti dal PS
