ARTICLE HIGHLIGHTS
Research background

In orthotopic liver transplantation (OLT) recipients, median arcuate ligament syndrome (MALS) is regarded as a risk factor for hepatic artery thrombosis (HAT), a devastating complication of OLT. To counteract the influence of MALS on transplantation, a variety of different surgical methods have been proposed, but clinical evidence is still lacking.

Research motivation

To increase the survival rate of MALS patients who receive OLT and decrease postoperative complications.

Research objectives

To evaluate the efficacy of surgical treatment for MALS to reduce complications in OLT patients in order to improve patient survival and decrease the incidence of postoperative complications.

Research methods

A total of 288 consecutive OLT patients at The First Hospital of Jilin University were retrospectively evaluated. Median arcuate ligament (MAL) surgical treatment and arterial anastomosis modification were recorded. Perioperative and long-term MALS prognoses were noted.

Research results

In this investigation, eight patients with MALS were enrolled. The first patient with MALS did not get any intervention during the main operation, and afterward developed HAT. Successful salvage liver transplantation with MAL division was accomplished. Gastroduodenal artery (GDA) preservation with splenic artery ligation was performed on three patients, GDA preservation alone was performed on two patients, and no intervention were performed on two patients. After surgery, no patient got HAT and healing was acceptable.

Research conclusions

The preservation of collateral circulation between the superior mesenteric artery and celiac trunk via the GDA, with or without ligation of the splenic artery, provides a safe and practicable alternative to MAL division.

Research perspectives

To provide surgeons with effective and feasible surgical options when they need to perform OLT in MALS patients.
