Low diameter porto-systemic shunts effectively treat portal hypertension bleeding in patients with good liver function. This surgical option offers a 77% adequate quality of life and 56% survival at 60 months.

Area of Science:

  • Vascular Surgery
  • Hepatology
  • Interventional Radiology

Background:

  • Portal hypertension bleeding is a serious complication of liver disease.
  • Low diameter porto-systemic shunts, enabled by PTFE vascular grafts, offer a new treatment approach.
  • Previous surgical options may not be feasible for all patients.

Purpose of the Study:

  • To report the 6-year experience with low diameter porto-systemic shunts for portal hypertension bleeding.
  • To evaluate the safety, efficacy, and long-term outcomes of this procedure.

Main Methods:

  • Retrospective analysis of 27 patients with good liver function (Child-Pugh A-B).
  • Patients underwent elective low diameter porto-systemic shunt surgery.
  • Outcomes assessed included operative mortality, rebleeding, encephalopathy, shunt patency, quality of life, and survival.

Main Results:

  • Operative mortality was 4%, with a 14% rebleeding rate.
  • Postoperative encephalopathy occurred in 52% of patients, mostly mild (11% Grade III-IV).
  • Shunt patency was 81%, with 77% reporting adequate quality of life and 56% survival at 60 months.

Conclusions:

  • Low diameter porto-systemic shunts are a viable alternative for managing portal hypertension bleeding.
  • The procedure demonstrates acceptable safety and efficacy in selected patients.
  • This technique provides a good quality of life and long-term survival for patients unsuitable for other procedures.
