Abstract

Objective: To describe the technique and outcomes of mesenteric access under ultrasound guidance to perform portal vein recanalization–transjugular intrahepatic portosystemic shunt (PVR-TIPS). Methods: Four patients (3 male: 1 female, mean age: 46.2 years; range 38–64 years) with portal vein thrombosis (PVT) and cavernous transformation were eligible for PVR-TIPS. Due to inaccessible splenic vein (one patient with history of splenectomy and 3 patients with unavailable splenic vein during the procedure), noninvasive direct puncture of superior (n = 3) and inferior (n = 1) mesenteric vein was conducted under ultrasound guidance to obtain access for PVR-TIPS. Results: Trans-mesenteric access and PVR-TIPS were successful in all patients at first attempt. No immediate complication was observed following the procedures. Follow-up imaging with computed tomography (CT) scan and Doppler ultrasound revealed patent TIPS and portal venous vasculature in all patients. Conclusion: Percutaneous noninvasive transmesenteric access is a feasible approach for PVR-TIPS in patients with inaccessible splenic veins.
