Abdominal contrast-enhanced computed tomography and digital subtraction angiography of superior mesenteric artery of the patient. (A) Abdominal contrast-enhanced computed tomography demonstrated a round abnormal enhancement (arrow) in the small intestinal lumen within the left upper quadrant. (B) Digital subtraction angiography of superior mesenteric artery demonstrated a rim-like staining (arrow) in the left upper quadrant. (C) A microcatheter was inserted into the feeding artery (arrow head); rim-like staining (arrow) was revealed after contrast medium injected in the microcatheter. (D) Digital subtraction angiography of the superior mesenteric artery demonstrated no contrast medium extravasation when the blood pressure was 90/70 mmHg. (E) Digital subtraction angiography of the superior mesenteric artery demonstrated contrast medium extravasated into the intestinal tract (arrow) when the blood pressure was raised to 120/80 mmHg. (F) Digital subtraction angiography of the superior mesenteric artery demonstrated no contrast medium extravasation after injection of 5 ml suspension of gelatin sponge particles (500 μm) and contrast medium.
