The direct intrahepatic portacaval shunt (DIPS) is a modification of the TIPS procedure, using intravascular ultrasound-guidance, combined with fluoroscopy. The DIPS procedure was initially conceived to increase the durability of shunt patency and extend the spectrum of patients with portal hypertension for whom endovascular portocaval shunting can be performed. The DIPS procedure involves intravascular ultrasound-guided puncture from the inferior vena cava to the portal vein through the caudate lobe of the liver. The shunt is completed with a polytetrafluoroethylene-covered stent graft. This article describes the indications, technique, and outcomes of the DIPS procedure to enable the interventional radiologist currently experienced with TIPS to incorporate this procedure into their practice.
