Fig. 3B —58-year-old man who underwent placement of supraceliac bypass to superior mesenteric artery (SMA) using reversed greater saphenous vein for typical symptoms of chronic mesenteric ischemia. One year after surgery, symptoms recurred that were found to be caused by stenosis of proximal graft anastomosis and 70% stenosis in SMA just distal to graft anastomosis on catheter angiography (not shown). Patient underwent recanalization of occluded proximal native SMA and placement of balloon-expandable stent as well as percutaneous transluminal angioplasty (PTA) of SMA just distal to anastomosis. Stenosis in graft was not treated. Follow-up MDCT angiogram 1 year later shows that antegrade graft is now occluded, presumably because of progression of intimal hyperplasia and reduced flow caused by patent SMA.
