[A case of complete recanalization in the lower abdominal aorta by intraaortic infusion of a thrombolytic agent].

Intraarterial infusion of thrombolytic agent is useful in the treatment of obstructive arterial diseases in various vessels. However, few studies have shown that this treatment is useful for aortic occlusion. We report the case with complete recanalization in the lower abdominal aorta following intraaortic infusion of a thrombolytic agent. A 59-year-old man was admitted because of weakness and pain in the bilateral lower limbs at rest. Aortography showed complete occlusion of the abdominal aorta proximal to the inferior mesenteric artery. Both external arteries were supplied via rich collaterals. He was treated by intraaortic urokinase infusion of 2,100,000 units. Total recanalization in the abdominal aorta and both common iliac arteries was obtained. Intraaortic infusion of urokinase was shown to be effective treatment of occlusion in the abdominal aorta.
