Figure 79A: Axial contrast-enhanced CT image of the upper abdomen demonstrates thrombus within the anterior abdominal aorta (arrow). Figure 79B: Axial contrast-enhanced CT image of the upper abdomen demonstrates multiple peripheral wedge-shaped regions of hypodensity in the spleen (arrowheads), compatible with splenic infarcts. Figure 79C: Sagittal contrast-enhanced CT image of the abdominal aorta demonstrates filling defects in the enlarged proximal celiac artery and mid and distal superior mesenteric artery, consistent with acute thromboemboli (arrows). Figure 79D: Axial contrast-enhanced CT image of the abdomen demonstrates absent mural enhancement of the small bowel (arrows). The bowel was nonviable during surgery.
