To evaluate techniques for retrograde pancreatic venography similar to epinephrine renal venography, 35 dogs had transjugular portography before and after the infusion of various doses of vasopressin systemically or selectively into the superior mesenteric and celiac arteries, or after occlusion of the distal thoracic aorta. Increased filling of the peripheral portal branches resulted, but none of the techniques provided diagnostically useful enhanced pancreatic visualization.

Experimental catheter obstruction of the left gastric (coronary) vein was explored in 10 dogs. Using a transjugular approach, the liver was punctured and the portal vein catheterized. Coaxially introduced catheters were then used to catheterize selectively and produce an intravascular obstruction (tamponade) of the gastric coronary vein. Ballon catheters were used for a temporary occlusion. Injection of a tissue adhesive, isobutyl 2-cyanoacrylate, was used for a definitive obliteration. The achieved results show the anatomical feasibility of this approach and give good perspective for development of a clinical method for percutaneous intravascular tamponade of the bleeding gastroesophageal varices in cirrhotics.
