Emergency Deceased Donor Liver Transplantation Using a PTFE Graft for Complex Arterial Reconstruction: A Technical...

Area of Science:

• Transplantation Surgery
• Vascular Surgery
• Hepatology

Background:

• Hepatic artery reconstruction is vital but challenging in liver transplantation.
• Anatomical variations and compromised flow complicate standard reconstruction techniques.
• Emergency liver transplantation presents unique vascular reconstruction challenges.

Purpose of the Study:

• To describe an emergency liver transplantation procedure using a polytetrafluoroethylene (PTFE) graft for hepatic artery reconstruction.
• To highlight the feasibility of PTFE grafts as a salvage option in complex cases.
• To present a novel approach for managing challenging hepatic artery reconstruction.

Main Methods:

• Emergency liver transplantation for hepatitis B virus-induced acute liver failure.
• Utilized a 6 × 40 mm polytetrafluoroethylene (PTFE) vascular graft for arterial reconstruction.
• Anastomosis between the infrarenal aorta and the donor's celiac trunk at splenic artery bifurcation.
• Retroperitoneal positioning of the PTFE graft to avoid small bowel complications.

Main Results:

• Successful restoration of arterial flow using a PTFE graft in a complex liver transplant scenario.
• Adequate graft perfusion achieved with adjusted arterial and portal flow rates.
• Demonstrated the technical feasibility of PTFE graft use when standard methods were exhausted.

Conclusions:

• Polytetrafluoroethylene (PTFE) grafts can serve as a feasible salvage solution for hepatic artery reconstruction in emergent liver transplantation.
• This technique is valuable when standard vascular reconstruction options are unavailable or contraindicated.
• The retroperitoneal placement minimizes risks associated with graft-bowel interaction.
