Management of isolated superior mesenteric artery dissection

Figure 1 Two overlapping stent-in-stent technique. A: Computed tomography angiography (CTA) showing a thrombus generated inside the false lumen, an ulcer-like niche intruding into the false lumen (indicated by the arrow); B: DSA demonstrating isolated superior mesenteric artery dissection (ISMAD) and narrowing of native lumen (arrow); C: Post two bare stent (a balloon-expandable and a self-expandable bare) deployment, repeat angiograph showing complete exclusion of the true lumen preserving patency of the superior mesenteric artery; D: Follow-up CTA at 5 mo, demonstrating disappearance of the false lumen and patency of true lumen (arrow).

Figure 2 Single bare stent technique. A: An isolated superior mesenteric artery dissection detected by computed tomography angiography (indicated by the arrow); B: Patent true lumen and the disappearance of the false lumen at 3 mo after single bare stenting.
