Traumatic abdominal aortic injury: clinical considerations for the diagnostic radiologist

Abstract: Traumatic abdominal aortic injury (TAAI) is a severe complication of penetrating and blunt trauma with significant morbidity and mortality, particularly if diagnosis is delayed. In patients with life-threatening injuries, accurate and prompt diagnosis of TAAI can be made with computed tomography (CT). Once the diagnosis of TAAI is made, the radiologist should provide an accurate description of the aortic lesion and the extent of injury in order to guide management whether it be non-operative, open aortic repai… Show more

“…A third model suggests that increased intraluminal pressure from compression may result in a "water hammer" eff ect that may help explain injury to the ascending thoracic aorta [24]. Within the abdomen, injury is thought to be due to compression of the aorta against the vertebral column [25]. While current studies seem to best support the rapid deceleration hypothesis, some combination of these mechanisms is most likely ultimately responsible for TAI.…”

“…18 Peritoneal lavage is a controversial procedure that carries a high risk of false positive or false negative results. 19 The emergency physician should look for lap belt marks, steering wheelshaped contusions, ecchymosis in the flanks and abdominal distension. Auscultatory bowel sounds and bruits may be present in diaphragmatic injury and indicate an underlying vascular disease.…”

“…Regarding ATAI of the abdominal aorta, penetrating trauma is the most frequent cause as blunt abdominal aortic injury is quite rare, comprising less than 1% of all blunt traumatic injuries (Figure 2) (16). The relative fixation of the abdominal aorta against the vertebral column predisposes it to injury from adjacent vertebral body fractures (1,17). The most commonly involved aortic segments are: infrarenal (67%), suprarenal (33%), and extension from a thoracic aortic injury (25%) (12).…”

“…For example, the identification of thoracic or lumbar vertebral body fractures should prompt a search for aortic injury at these levels. Similarly, the retroperitoneal organs should be evaluated, given the high association between organ injury and aortic trauma (17). A meticulous search for retroperitoneal hematoma and periaortic fat stranding is also essential given that these signs are sensitive for abdominal aortic injury detection (Figure 2) (12,17,30).…”
