A case of spontaneous dissection of the superior mesenteric artery.

Spontaneous Dissection of the Superior Mesenteric Artery in Four Cases Treated with Anticoagulation Therapy

“…The condition is characterized by the sudden onset of abdominal pain or back pain, and symptom aggravation after meals or attenuation of intestinal murmur. Upper abdomen bruit, which was confirmed in three of the present cases, is regarded as an important physical finding of this disease (6). However, it is difficult to distinguish this from other types of acute abdomen based on clinical symptoms.…”

Spontaneous isolated dissection of the superior mesenteric artery

“…In 20 cases the location of the dissection was described. It was located in the proximal part of the SMA within the first centimetre in 4 cases 13,18,26 (patient 3), and between 1.5 and 3 cm in 15 cases 8±12, 15,17,19,20,22,23,28,29,31 (patient 2), and after 4 cm in one case. 24 Solis 17 hypothesised that the dissection was caused by the stress on the arterial wall at the inferior edge of the pancreas, where the transition from the fixed and to the mobile part of the SAM takes place.…”

“…It was normal in three cases. 10,13,15 In one case, 32 CT scan showed a 90% stenosis of the SMA associated with signs of small bowel ischaemia. In the remaining case, 19 the authors described an image of``an opaque mass located anteriorly in the proximal segment of the SMA'' without another precision.…”

Three isolated superior mesenteric artery dissections: Update of previous case reports, diagnostics, and treatment options

“…Aortomesenteric bypass 14,16,17,21,23,28,33,34 is the most common surgical procedure (8 of 34, 23.5%). Patch angioplasty with or without intimectomy 2,13,17,19,23 and endoaneurysmorraphy 17,29,41 are the most basic surgical revascularization procedures (9 of 34, 26.5%) and have shown good short-term outcomes without failure or reoperation.…”
