Diagnostic Accuracy of Multidetector Computed Tomography in Evaluation of Retroperitoneal Traumatic Injuries and Retroperitoneal Hemorrhage

Abstract
Background: Abdominal trauma represents a main daycare activity in radiology.non surgical treatment has become the standard of care in hemodynamically stable abdominal trauma patients as a result of comprehensive assessment of injury by imaging.
MDCT is very sensitive method to detect traumatic injuries and determine the grading of this injuries on which the management will be performed.
Aim of Study: To assess diagnostic accuracy of multi-detector CT in evaluation of retroperitoneal traumatic injuries and retroperitoneal hemorrhage.
Patients and Methods: Prospective study included 60 patients with abdominal trauma (40 male, 20 females), their age ranged from 7 years to 70 years (mean age 34.8 year). Ultrasonography and MDCT were performed for all patients.
Results: 30 patients (50% of the total studied patients) had retroperitoneal injuries, 27 patients of them (90%) were secondary to blunt abdominal trauma and 3 patients (10%) suffered from stab trauma. Fifteen patients had renal injuries; 3 of them associated with adrenal injuries, 2 patients had bowel injuries, 5 patients had pancreatic injuries, 3 patients had vascular injuries and 5 patients had retroperitoneal hematoma related to other injuries; 3 of them had psoas muscle injury and the other 2 patients had urinary bladder rupture.
Conclusion: MDCT proved to be accurate and sensitive to evaluate retroperitoneal traumatic injuries and determine the grading and severity of these injuries on which the man-agement will be performed. In addition MDCT proved to be highly sensitive in detection of active hemorrhage which is a life threatening condition.
