Imaging in renal trauma

Figure 9 Grade V injury. Renal vascular injury. Devascularization following renal artery thrombosis. A: Axial contrast enhanced computed tomography (CECT) section at the level of left renal artery of a 48-year-old male patient who had blunt trauma to the abdomen, showing non-enhancing left kidney with abrupt cutoff of the enhancing proximal segment of left main renal artery (arrow) with non enhancing distal segment; B: Axial CECT scan of a different patient shows reflux of contrast in to the right renal vein (arrow) from inferior vena cave of the decasualized right kidney, also a sign seen in devascularized kidneys.
