The Role of CT Scan in Recognizing Blunt Diaphragmatic Rupture

Abstract

ABSTRACT Background Blunt traumatic diaphragmatic rupture (BTDR) occurs when signicant deceleration mechanism and energy are applied to the torso, and it is associated with signicant injuries and high morbidity and mortality. Although it has limitations, CT scan is the diagnostic of choice for BTDR. This study is a retrospective analyse of our experience in diagnosing BTDR using the 64-slice CT scanner. Sensitivity and specicity of this exam were assessed. Methods We reviewed reports from 2006 to 2009 of all CT scans of the abdomen that were done in the rst 24 hours of hospitalization of blunt trauma patients. We compared CT ndings to surgery reports. Results Our cohort consisted of 2670 patients; 69% were male. We found 28 cases of BTDR, most of them on the patient s left side (54%). Eleven percent of cases were bilateral. BTDR was often caused by motor vehicle collisions. We found sensitivity of 86%, specicity of 99%. Conclusion CT scan is reliable tool in blunt trauma patients. As new technologies arise, its sensibility and specicity also increases. How to cite this article Passos E, Nascimento B, Netto FS, Tien H, Rizoli S.
