Insights
A novel technique reconstructs damaged supra-hepatic inferior vena cava (IVC) in liver grafts using infra-hepatic IVC segments. This method salvages potentially discarded liver allografts, improving organ utilization in transplantation.
Area of Science:
- Organ transplantation
- Surgical innovation
- Vascular reconstruction
Background:
- Procurement teams sometimes damage the supra-hepatic inferior vena cava (IVC) during organ harvesting.
- This damage can make liver allografts unsuitable for transplantation due to inadequate length for anastomosis.
- Discarding viable liver grafts represents a significant loss of transplantable organs.
Purpose of the Study:
- To describe a technique for reconstructing the supra-hepatic IVC in liver allografts.
- To salvage liver grafts with compromised supra-hepatic IVC length.
- To reduce the discard rate of liver allografts due to vascular anomalies.
Main Methods:
- Utilizing a segment of the infra-hepatic inferior vena cava (IVC) from the liver graft.
- Performing a reconstruction of the damaged supra-hepatic IVC using the harvested infra-hepatic IVC segment.
- Ensuring adequate length for successful anastomosis with the recipient's vasculature.
Main Results:
- Successful reconstruction of the supra-hepatic IVC was achieved.
- The technique allowed for the successful transplantation of previously unsuitable liver allografts.
- Demonstrated the viability of using infra-hepatic IVC segments for supra-hepatic IVC repair.
Conclusions:
- This reconstructive technique offers a viable solution for managing damaged supra-hepatic IVCs in liver allografts.
- Salvaging these grafts increases the availability of organs for liver transplantation.
- Highlights the importance of innovative surgical approaches in organ procurement and transplantation.
Abstract:
During deceased donor procurement, the heart procurement team may cut the supra-hepatic inferior vena cava (IVC) too close to the liver surface, depriving the liver allograft from having enough supra-hepatic IVC to perform the anastomosis with the recipient's IVC or hepatic veins. In such instances, liver grafts usually are deemed as non-appropriate for transplantation, being discarded. Here we report a technique for reconstruction of damaged supra-hepatic IVCs through the use of a segment of the infra-hepatic IVC of the liver graft.
