Spiral computed tomography with three-dimensional reconstructions for severe blunt abdominal traumas: a useful...

Spiral computed tomography (CT) has proved to be a valuable tool by providing three-dimensional (3D) images of the studied structures. We hypothesized that a more realistic depiction of lesions by 3D CT could be of interest for surgeons who are treating blunt abdominal traumas and lead to less inappropriate triage. A good working relationship between surgeons and radiologists allowed us to perform a 3D CT examination in six patients. In the first patient, the 3D CT accurately demonstrated spleen fragmentation without devascularized fragment. The second patient had complete devascularization of the spleen upper pole. Conservative treatment was pursued for both patients. For the third patient, 3D CT helped us to differentiate peritoneal-perisplenic fluid from subcapsular fluid. The fourth patient had minor spleen injury associated with severe lacerations of the left kidney. 3D CT showed a complete separation of the kidney lower pole. A delayed partial lower nephrectomy was performed. The fifth patient presented a fragmented spleen and transient massive haematuria related to a well-contained laceration of the kidney upper pole that were amenable to nonoperative management. The sixth patient was emergency operated for active bleeding from a fragmented spleen. 3D CT performed 2 months after spleen repair allowed the assessment of the amount of devascularized tissue, as well as the status of the upper abdomen arteries. For haemodynamically stable patients, 3D CT could be a helpful addition to conventional axial CT for quantifying blunt abdominal traumas, for making the choice between nonoperative and operative treatment, but also between emergency and delayed surgical strategy.
