Fig. 1 Diagnosis and treatment of patient with isolated superior mesenteric artery rupture. (a) No abnormal changes were observed upon abdominal inspection. (b, c) The abdominal computed tomography (CT) suggested the ruptured superior mesenteric artery (arrow in b) and blood accumulation around the small intestine (arrow in c). (d) Digital subtraction angiography (DSA) revealed extravasation of contrast medium (white arrow). (e) No extravasation of contrast medium was seen on the angiographic review after treatment. (f) The lumens of the superior and inferior mesenteric arteries were well filled with contrast medium, and there were no signs of stenosis or dilation. A: anterior; R: right; L: left; P: posterior.
