Figure 7 Angiographic result of covered stent placement for proximal superior mesenteric artery stenosis. A: Lateral digital subtraction angiographic image via a 6-Fr sheath at the ostium of the superior mesenteric artery demonstrating severe proximal stenosis (arrow); B: Corresponding image following covered stent placement demonstrating improved flow across the treated segment, with residual stenosis of approximately 20% secondary to extensive calcified atherosclerosis (arrow). Same patient as Figures 5 and 6.
