Experimental transjugular portacaval shunt. Use of a fine-needle puncture device for the implantation of Strecker stents.
A transjugular portacaval intrahepatic stented shunt was created in 16 pigs without induced portal hypertension. A fine needle (OD 0.7 mm) was used for the transjugular puncture of the portal vein. The puncture was done directly from the inferior vena cava in 5 cases and from the right liver vein in 11 cases. The puncture tract was dilated and subsequently supported by a Strecker stent. The stented shunt was patent in all cases immediately after the stent placement, but was obstructed by fibrous tissue in 7 of 8 cases reexamined by angiography and autopsy after 4 weeks. Complications seem to be related to the choice of the puncture site, with fewer complications when the puncture was done via the right hepatic vein.
