Superior mesenteric artery thrombosis usually occurs in an area of severe atherosclerotic narrowing, most often at the origin of the superior mesenteric artery. On angiography, the absence of collateral vessels or the presence of collaterals with inadequate filling of the superior mesenteric artery indicates an acute occlusion and demands prompt intervention. A 44-year-old man presented with epigastric and right upper quadrant pain after eating. Computed tomography and angiography showed superior mesenteric artery thrombosis. After treating with intra-arterial infusion of urokinase and intraluminal stent insertion, the patient showed clinical improvement and near complete resolution of superior mesenteric artery thrombosis. Thus, direct infusion of urokinase into the superior mesenteric artery and angioplasty with stenting for treatment of superior mesenteric artery thrombosis can be the alternative to surgery in selected patients with superior mesenteric artery thrombosis.
