[A case of multiple aneurysms originated from the superior mesenteric artery branch, and a review of literature].
A case of multiple aneurysm of superior mesenteric artery (SMA) branch is presented. A 54-year-old man with sudden onset of back pain was admitted to our hospital. Severe abdominal pain was developed and he fell into shock. Selective angiography of the SMA demonstrated aneurysm of the accessory middle colic artery to splenic flexure. Laparotomy disclosed much intraperitoneal blood and a large clot under the pancreatic body with a gushing hemorrhage. The bleeding vessel was ligated and sutured. The postoperative course was uneventful, but the subsequent angiography revealed another aneurysm of SMA branch, which was not able to be seen in the previous angiography because of overlapping with main SMA trunk. Resection of the aneurysm was done. The etiology of the latter aneurysm was suggested to be medial degeneration histologically. Fourty-nine cases of SMA aneurysm from the Japanese literature were reviewed and discussed. Emphasis is placed on early diagnostic laparotomy for appropriate management and the role of angiography in confirmation of bleeding site in case of spontaneous intraabdominal hemorrhage.
