Representative CT scan findings. A: shown is the entry of the dissection at the proximal SMA. An abnormal origin of the right hepatic artery from the proximal SMA can be seen as an anatomical variant. B: An embolism of a distal branch of the SMA is shown. C: Reconstruction of the CT scan after admission. Almost complete decline of intestinal perfusion of the right abdominal side could be observed. D: findings of the control CT scan 5 days after operation. No residual membrane could be observed, normal perfusion of the SMA and the right hepatic artery.
