[Traumatic retroperitoneal haematoma]

The management of traumatic retroperitoneal haematomas is still a much debated question. Although the diagnosis has become easier using CT with contrast medium, the therapeutic decisions are still difficult because of the great variability of the lesions, which may be simple but very often complicated. Our study is based on 1086 treated patients, 29.5% of the 3682 critical abdominal polytrauma seen in 35 years. Mortality has been 12.9% with a medium ISS (Injury Severity Score) of 23.4. 71.4% of the cases were closed traumas, 28,6% were open traumas. The most common single lesions have been pelvic (43%), followed by the renal traumas (39%). Regarding the associated lesions, the thoracic traumas cause an increment of the ISS score up to 26.2% and of mortality up to 14.6%. The maxillofacial traumas associated with traumatic retroperitoneal haematomas represent 11%, mainly associated with motorcycle accidents, which have increased in the last years from 2,4% in the 70s to 32% these days. Our approach to these patients has been basically conservative. Following the indications obtained by the CT, we widely used interventional angiography, especially for renal lesions and, after pelvic stabilization, for pelvic haematomas. We have chosen surgery considering the kind of traumas (open or closed), the location of the haematoma and especially, the clinical course of the patient's hemodynamic condition.
