Impact of Splenic Artery Ligation in LDLT for Patients With Portal Hypertension

Overview

In this study, the investigators aim to prove that performing splenic artery ligation in living donor liver transplantation for patients with portal hypertension is beneficial for early graft function postoperatively. The investigators will be analyzing trend of LFT's (liver function tests) after surgery, time for normalization of bilirubin, INR (international normalised ratio) and decrease in ascites, morbidity, mortality, ICU (intensive care unit) and total hospital stay.

Liver transplantation (LT) is the principal treatment for end-stage liver diseases and selected cases of liver neoplasms . Living donor liver transplantation (LDLT) serves as a sole source of liver graft in some countries that do not allow donation from deceased donors for cultural, social, or religious reasons. Hyperperfusion plays an important role in liver regeneration after LDLT, but it may induce injury in the graft . After the reperfusion of a partial graft, there is a significant increase in the portal flow, but Hepatic artery flow remains constant . Excessive portal vein flow may induce injuries in grafts and may contribute to poor graft function. For satisfactory graft function early after LT, the portal vein pressure (PVP) value after reperfusion should be \<15 mm Hg. PVP is the most important hemodynamic factor influencing the functional status of the liver and graft regeneration after LT. The use of Splenic Artery Ligation (SAL) as a simple and safe method to modulate portal flow has been reported . The investigators will evaluate that Splenic artery ligation in living donor liver transplantation for patients with Portal hypertension is feasible and efficient technique to improve early graft function and to decrease morbidity and hospital stay and improve outcomes .
