CT shows a narrow angle and reduced distance between the aorta and SMA. (A) The distance between the aorta and SMA was 12 mm on preoperative CT. (B) The distance between the aorta and SMA on postoperative CTwas 2mm. (C, D) The angle between the aorta and SMA on postoperative CT was 36°. Localization of the pouch deep in the pelvis causes relative stretching of the SMA and flattens it against the aorta in the retroperitoneum.
