[Indexed for MEDLINE] 12. Radiographics. 2022 Mar-Apr;42(2):E50-E67. doi: 10.1148/rg.210092. Roles of Trauma CT and CTA in Salvaging the Threatened or Mangled Extremity. Dreizin D(1), Smith EB(1), Champ K(1), Morrison JJ(1). Author information: (1)From the Division of Trauma and Emergency Radiology (D.D., E.B.S.), Department of Diagnostic Radiology and Nuclear Medicine (D.D., E.B.S., K.C.), and Department of Vascular Surgery (J.J.M.), University of Maryland and R Adams Cowley Shock Trauma Center, 655 W Baltimore St, Baltimore, MD 21201. Extremity arterial injuries account for up to 50% of all arterial traumas. The speed, accuracy, reproducibility, and close proximity of modern CT scanners to the trauma bay have led to the liberal use of CT angiography (CTA) when a limb is in ischemic jeopardy or is a potential source of life-threatening hemorrhage. The radiologist plays a critical role in the rapid communication of findings related to vessel transection and occlusion. Another role of CT that is often overlooked involves adding value to surgical planning. The following are some of the key questions addressed in this review: How does CTA help determine whether a limb is salvageable? How do concurrent multisystem injuries affect decision making? Which arterial injuries can be safely managed with observation alone? What damage control techniques are used to address compartment syndrome and hemorrhage? What options are available for definitive revascularization? Ideally, the radiologist should be familiar with the widely used Gustilo-Anderson open-fracture classification system, which was developed to prognosticate the likelihood of a functional limb salvage on the basis of soft-tissue and bone loss. When functional salvage is feasible or urgent hemorrhage control is required, communication with trauma surgeon colleagues is augmented by an understanding of the unique surgical, endovascular, and hybrid approaches available for each anatomic region of the upper and lower extremities. The radiologist should also be familiar with the common postoperative appearances of staged vascular, orthopedic, and plastic reconstructions for efficient clinically relevant reporting of potential down-range complications.
