Intraarterial digital subtraction portography in patients with liver tumors.
Intraarterial digital subtraction portography (IADSP) via the superior mesenteric artery was performed in 50 patients with liver tumors. In most cases IADSPs provided images as good as conventional arterial portography through the superior mesenteric artery and they produced important information as to whether patients should be treated by transcatheter arterial embolization, surgical resection or chemotherapy. IADSP helps to reduce the examination time, the number of films and contrast material used, as well as the pain suffered by patients.
