Conservative management of spontaneous isolated superior mesenteric artery dissection: A case report

Takashi Miyata et al. Clin Case Rep. .

Abstract

Spontaneous isolated superior mesenteric artery dissection (SISMAD) is a rare and potentially fatal cause diagnosis presenting with acute abdominal; however, because of its rarity, the pathogenic factors of SISMAD remain unknown and no clear cause has been found. Moreover, there is a lack of evidence-based treatment guidelines.

Keywords: conservative therapy; spontaneous dissection; superior mesenteric artery.

Initial imaging findings. Initial axial and sagittal imaging by enhanced abdominal computed tomography (CT) shows spontaneous isolated superior mesenteric artery (SMA) dissection (SISMAD) (A, B, red arrow) with extension into the ileocolic artery (C, red arrow)

Three‐dimensional CT angiogram. The arterial arcade from MCA (yellow arrows) and SISMAD (red arrow) are shown

FIGURE 3
Follow‐up CT after 7 days. Enhanced abdominal CT after 7 days admission shows the false lumen of the SMA (A, B, red arrow) and the ileocolic artery (C, red arrow) are smaller and the true lumen is slightly more open than in the initial CT images
