“…With the development of EUS technique, EUS can be used for diverse procedures including drainage for pancreaticobiliary disease, celiac plexus intervention, vascular intervention, and natural orifice transluminal endoscopic surgery. [ 2 3 4 5 6 21 22 ] Intra-abdominal vascular access and therapy are promising areas within the field of EUS-guided intervention; therefore, several clinical or experimental studies have examined EUS-guided vascular interventions. [ 5 6 ] Experimental studies show that EUS-guided PV catheterization and PV pressure measurement in a porcine model are technically feasible.…”

Background and Objectives:Percutaneous portal vein (PV) stent placement is used to manage PV occlusion or stenosis caused by malignancy. The use of endoscopic ultrasonography (EUS) has expanded to include vascular interventions. The aim of this study was to examine the technical feasibility and safety of EUS-guided transhepatic PV stent placement in a live porcine model.Materials and Methods:EUS-guided transhepatic PV stent placement was performed in six male miniature pigs under general anesthesia using forward-viewing echoendoscope. Under EUS guidance, the left intrahepatic PV was punctured with a 19-gauge fine-needle aspiration (FNA) needle and a 0.025 inch guidewire inserted through the needle and into the main PV. The FNA needle was then withdrawn and a needle-knife inserted to dilate the tract. Under EUS and fluoroscopic guidance, a noncovered metal stent was inserted over the guidewire and released into the main PV.Results:A PV stent was placed successfully in all six pigs with no technical problems or complications. The patency of the stent in the main PV was confirmed using color Doppler EUS and transhepatic portal venography. Necropsy of the first three animals revealed no evidence of bleeding and damage to intra-abdominal organs or vessels. No complications occurred in the remaining three animals during the 8 weeks observation period.Conclusions:EUS-guided transhepatic PV stent placement can be both technically feasible and safe in a live animal model.

“…Endoscopic ultrasonography (EUS) and EUS-guided interventions are often used to diagnose and manage intra-abdominal diseases. [ 1 2 3 4 ] More recently, EUS has been used to diagnose and treat vascular conditions. [ 5 6 7 8 ] EUS-guided coil embolization or cyanoacrylate injections have been used to manage gastric varices.…”
