Abstract:
OBJECTIVETo investigate the characteristics of the spontaneous isolated superior mesenteric artery dissection (SISMAD) on computed tomography angiography (CTA).
METHODSTwenty-five patients with unexplained acute abdominal pain received CTA.
RESULTSFour cases with the SISMAD were found and all were male with a mean age of (45.3±6.7) years. Two patients had hypertension history. CT showed enlarged diameter of the superior mesenteric artery with dissection in 4 cases, intimal flap and visible false lumen in 2 cases, ulcer-like laceration in 1 case, and intramural hematoma in 1 case. The proximal lacerations or entries were all at the proximal segment of the superior mesenteric artery. CTA classifications were type Ia (n=2), IIb (n=1), and III (n=1). Two patients underwent repeated CTA when discharged, and progressive changes were discovered.
CONCLUSIONCTA can clearly show the characteristics of the superior mesenteric artery dissection, confirm the diagnosis, and provide an important basis for the classification and follow-up observation.
