RESUMO
Temporary abdominal closure (TAC) has increasingly been employed in the management of severely injured patients to avoid abdominal compartment syndrome (ACS) and as part of damage control surgery (DCS). Although the use of TAC has received great interest, few data exist describing the morbidity and mortality associated with its use in trauma victims. The main goal of this study is to describe the incidence of surgical complications following the use of TAC as well as to define the mortality associated with this procedure. A retrospective review of patients admitted to a state-designated level 1 trauma center from April 2000 to February 2003 was performed. Inclusion criteria were age >18 years, traumatic injury, and need for exploratory laparotomy and use of TAC. A total of 120 patients were included in the study. The overall mortality of trauma patients requiring TAC was 59.2 per cent. The most common causes of death were acute inflammatory process (50.7%), followed by hypovolemic shock (43.7%). The incidence of surgical complications was 26.6 per cent. Intra-abdominal abscesses were the most frequent surgical complication (10%). After multiple logistic regression analysis, increasing age and a numerically greater initial base deficit were found to be independent predictors of mortality in trauma patients that require TAC.

BACKGROUND: The radiologic study of choice for evaluation of traumatic arterial injuries is conventional arteriography, but it poses the risks of an invasive procedure. Computed tomographic arteriography (CTA) is emerging as a new way to study arterial anatomy, with the additional advantages of being noninvasive and a technique that allows evaluation of different body areas simultaneously. Our experience using CTA for evaluation of traumatic arterial injuries is provided in this study. METHODS: A retrospective review over a 22-month period of all adult patients undergoing CTA for evaluation of traumatic injuries to the extremities was performed. RESULTS: A total of 97 CTA studies were performed in the 95 patients. CTA adequately demonstrated the nature and location of all the arterial injuries when compared with conventional arteriography or surgical exploration. Abnormal CTA results included 21 arterial occlusions, 2 intimal flap defects, and 2 pseudoaneurysms. Nine of these 25 injuries were confirmed by surgery only, 10 by surgery and arteriography, and 6 by arteriography only. Normal CTA results were confirmed with arteriography in 10 cases. No missed injuries were encountered in patients with normal CTA results. CONCLUSION: CTA is a reliable technique for the detection and characterization of traumatic extremity arterial injuries. These results suggest CTA may be an alternative to conventional arteriography for the diagnosis of traumatic arterial injuries.
