Abstract:
Objective To investigate some improvements in the surgical techniques of adult-to-adult living donor liver transplantation( A-A LDLT) without the middle hepatic vein(MHV) for hepat-ic vein reconstruction. Methods The retrospective analysis was made on the clinical data of 11 recipi-ents who underwent the operation in A-A LDLT including the hepatic vein reconstructed in right liver lobe without MHV from June 2007 to January 2008. The key techniques included reconstructing out-flow of graft on shaping the tips of vena cava and right hepatic veins, cadaveric vein allografts stored in 4℃ UW solution within 7d being used for significant-sized hepatic vein reconstruction such as tributa-ries of the middle hepatic vein from V5, V8 and right inferior hepatic vein. Results 10 cases success-fully underwent reconstruction of outflow of graft on shaping the tips of vena cava and right hepatic veins and the outflow reconstruction ratio of V5, V8 and right inferior hepatic vein was 81. 8% (9/11), 7 one-vein reconstruction, 1 two-vein reconstruction and 1 three-vein reconstruction. 1 recipient died of renal failure and pulmonary infection 14 days after operation without venous outflow obstruc-tion. Doppler ultrasonography showed no thrombosis and the blood flowed smoothly in the right he-patic vein of other 8 recipients during the 9th to 15th mouth of follow-up. The cumulative patency rates of these 8 survivals for interposition vein grafts were 100% (11/11), 72. 7 %(8/11), 54. 5%(6/11) and 36. 5%(4/11) in 1, 3, 6 and 9 mouths, respectively. The regeneration of paramedian sectors was equivalent. Conclusion Shaping the tips of vena cava and right hepatic veins and using cadaveric vein allografts in adult-to-adult right lobe living donor liver transplantation for hepatic vein reconstruc-tion are both safe,simple and effective methods.This approach can be recommended.
