Summary
Single arterial reconstruction for left liver grafts with two arterial stumps is safe in living donor liver transplantation. This approach did not impact patient survival or biliary complications when specific criteria were met.
Area of Science:
- Surgical Innovation
- Transplant Surgery
- Vascular Reconstruction
Background:
- Living donor liver transplantation frequently involves left liver grafts with dual arterial stumps.
- The necessity of multiple arterial reconstructions in such cases is debated.
- This study evaluates the impact of single anastomosis on graft outcomes.
Purpose of the Study:
- To determine if single arterial reconstruction of left liver grafts with two stumps affects outcomes in living donor liver transplantation.
- To compare outcomes between single and double arterial reconstructions.
Main Methods:
- Retrospective analysis of 134 left liver grafts.
- Grafts were categorized into one (n=70), or two (n=59) arterial stumps with single reconstruction, and two stumps with double reconstruction (n=5).
- Hepatic arterial thrombosis, biliary stenosis, and patient survival were compared between single reconstruction groups.
Main Results:
- No significant differences in hepatic arterial thrombosis incidence were observed between groups.
- Biliary stenosis rates were comparable between groups.
- Patient survival curves showed no significant variations.
Conclusions:
- Single arterial reconstruction for left liver grafts with two stumps is a viable option.
- This technique does not negatively impact patient survival or lead to increased biliary complications.
- Adherence to reconstruction criteria ensures favorable outcomes.
