Liver Retransplantation: The Changing Scenario in a Tertiary Medical Center

Area of Science:

• Hepatology
• Transplant Surgery
• Medical Research

Background:

• Liver retransplantation (LRT) is a critical procedure for patients with graft failure.
• Understanding the specific causes of LRT is essential for improving patient outcomes and optimizing transplant strategies.

Purpose of the Study:

• To investigate the primary indications for liver retransplantation.
• To analyze recipient and donor factors influencing LRT.
• To evaluate the survival rates and complications associated with LRT.

Main Methods:

• A descriptive, observational, and unicentric study was conducted.
• Data from patients undergoing LRT between April 2002 and December 2018 were collected.
• Recipient, donor, and liver transplant details were analyzed.

Main Results:

• The study identified hepatic artery thrombosis (HAT) as the most frequent indication for LRT (25%), followed by chronic rejection (21.8%).
• The overall LRT rate was 6.8%, with 71.8% of procedures being late LRT.
• Recipient survival rates at 3, 6, and 12 months were 72.7%, 54.6%, and 51.5%, respectively, with 5-year survival at 46.8%. Septic shock was the leading cause of death (42.1%).

Conclusions:

• Hepatic artery thrombosis (HAT) is the predominant cause of liver retransplantation in this cohort.
• The observed LRT rate aligns with national and international data.
• Improving management of HAT and post-transplant complications is crucial for enhancing LRT outcomes.
