BACKGROUND: To investigate the application of the superior mesenteric artery (SMA) for the in vitro reconstruction of the hepatic artery for liver transplantation, and to improve the success rate and safety of donor liver transplantation.
METHODS: The donor liver and the pancreas were obtained, and the SMA and its branches were used to reconstruct the hepatic artery. Liver transplantation was performed after reconstruction to understand the intraoperative situation after donor liver opening, as well as postoperative liver function. Color Doppler ultrasound of the transplanted liver was also performed.
RESULTS: During the period from September 2016 to March 2020, a total of 98 pancreases were obtained. The common hepatic artery and gastroduodenal artery loop (CHA-GDA) were preserved to the donor pancreas, and only the proper hepatic artery (PHA) or left/right hepatic artery (LHA/RHA) were preserved to the donor liver. If the PHA of the donor liver was short or absent, the SMA was used for lengthening the PHA or in vitro reconstruction of the LHA/RHA, followed by implantation of the donor liver after reconstruction. A total of 17 cases of this type of donor liver required mesenteric artery lengthening or reconstruction. After opening, the donor liver was well-filled, bile secretion was normal, and liver function recovered as scheduled after surgery. Color Doppler ultrasound and CT angiography (CTA) of the transplanted liver revealed that hepatic arteries were normal without complications such as hepatic artery embolism.
CONCLUSIONS: In vitro reconstruction of the hepatic artery with the SMA is an effective new method of vascular reconstruction, which ensures the blood flow of the hepatic artery, reduces the anastomosis difficulty of the arteries of the donor liver, and reduces the occurrence of vascular complications.
