[Lesions of the spleen caused by blunt trauma. Proposal of a classification based on CT and correlation with prognosis and treatment].

The use of CT scan has had a profound influence on the evaluation and treatment of closed abdominal injuries, enabling a progressive reduction to be achieved in the total number of emergency laparotomies. The authors review CT performed over the past two years in adult hemodynamically stable patients with traumatic splenic lesions. In 19 cases it was possible to commence non-surgical treatment which was successful in 18/19 cases. A simple and precise scoring system was elaborated on the basis of data obtained from CT by evaluating 4 parameters: extent of free intraperitoneal effusion, concomitant lesions to other abdominal organs, severity and site of splenic lesion. This classification gives a high degree of prognostic accuracy and provides a useful guideline in the choice of the most appropriate treatment.
