Ruptured aneurysm of the middle colic artery is very rare. Its concomitance with isolated dissection of the superior mesenteric artery (SMAD) has not yet been reported in the literature.Case report:
A previously well 56-year-old man was referred to our hospital with acute-onset pain throughout the entire abdomen. A ruptured aneurysm of the middle colic artery and isolated SMAD were revealed using a computed tomography (CT) scan. Coil embolization was successfully performed for a ruptured aneurysm of the middle colic artery. During the immediate postprocedural period, the patient had ischemic colitis, but he recovered in a few days with conservative treatment. Close observation was elected to address the SMAD because the condition was not thought to be responsible for any symptoms. The CT scan followed after 2 years showed no change in SMAD.Conclusions:
We successfully performed endovascular treatment for a ruptured aneurysm of the middle colic artery. For the incidentally detected SMAD, close observational management was chosen.
