Temporary portocaval Shunt during recipient hepatectomy improves intra operative parameters and morbidity in LDLT recipients
All patients satisfying the inclusion criteria, written informed consent will be taken and patients are randomized into intervention group ( Portocaval Shunt Group) and Non intervention group ( No Shunt Group).Patients from both the groups will be assessed for Hemodynamic parameters, Urine Output, Blood loss, blood products requirement , Duration of surgery during the procedure. They will be assessed for renal function, presence of sepsis, Morbidity, early graft dysfunction, ICU stay and total hospital stay in the post operative period.All patients will be followed up till discharge from hospital.
