[Infusion therapy for acute superior mesenteric artery occlusion].

We performed transcatheter fibrolytic therapy using a coaxial microcatheter in two cases of acute superior mesenteric artery occlusion in the early stage. The tip of the microcatheter was introduced into the clot of the superior mesenteric artery. Urokinase was infused at a rate of 10,000 IU/min. The clots dissolved immediately after the infusion of 240,000 IU and 480,000 IU, respectively, without any complications. This infusion technique is promising for the treatment of acute superior mesenteric artery occlusion.
