Intravascular Ultrasound-Guided Mesocaval Shunt Creation in Patients with Portal or Mesenteric Venous Occlusion

Extrahepatic mesocaval shunts were successfully created in three patients with refractory variceal hemorrhage, complete portal vein or superior mesenteric vein occlusion, and contraindications to shunt surgery. The use of intravascular ultrasound guidance and covered stents allowed safe and effective transvenous shunt creation without the necessity of percutaneous transabdominal mesenteric venous puncture.
