Indirect mesentericoportography with prostaglandin E1

Indirect mesenteriocoportography was performed in 36 patients after administration of prostaglandin E1 and immediately before contrast medium injection. The results were compared with the findings in a control group of 20 patients receiving tolazolin as vasodilator. On comparing prostaglandin E1 with tolazolin no significant improvement in contrast enhancement of the superior mesentric vein was obtained. On the other hand, prostaglandin E1 seemed to produce less side effects than tolazolin. (Author)
