ABSTRACT

Objective:To explore the feasibility, safety and effectivity of applying transmesenteric vein extrahepatic portosystemic shunt (TEPS) to treat extrahepatic portal vein obstructive disease (EHPVOD).Methods:From December 2020 to April 2021, 12 patients with EHPVOD in the Vascular Surgery Department of Zhengzhou University People′s Hospital were prospectively enrolled in the study. The infra-umbilical median longitudinal minilaparotomy was performed to expose the branch of superior mesenteric vein (SMV). RUPS-100 was introduced into the trunk of SMV. A balloon with a diameter of 20 mm was introduced through right internal jugular vein (RIJV) into inferior vena cava (IVC). Under fluoroscopy, RUPS-100 was used to puncture the balloon in IVC. A stiff guide wire was used to establish the pathway between RIJV and SMV. Finally the portosystemic shunt between IVC and SMV was established with a covered stent-graft. The total operative time, the time of establishing portosystemic shunt alone, the dosage of contrast agent, the preoperative and postoperative pressure of SMV were recorded. Paired t test was used to compare the preoperative and postoperative pressure of SMV. Results:All 12 patients were successfully performed TEPS. The total operative time was (113±32) min, the time of establishing portosystemic shunt alone was (31±5) min, the dosage of contrast agent was (129±48) ml. The postoperative pressure of SMV [(14.3±2.1) mmHg] decreased significantly ( t=20.125, P<0.01) compared to baseline [(27.8±2.7) mmHg]. All portal hypertension symptoms released after the operations.There was 1 case of delayed incision healing, 1 case of bacteremia and 1 case of slight hepatic encephalopathy, but all of them were cured. There was no death case. Postoperative CT showed all portosystemic shunts were patent. Conclusion:TEPS is a new, safe, effective and feasible treatment method for patients of acute and chronic EHPVOD.
