Q) The significance of MELD Scoring in Liver transplant is :
a) Less ill patients are given more priority in liver transplant
b) Set threshold for patients who are too ill to undergo transplant.
c) To access mortality in the waiting list.
d) To list patients in cadaveric deceased donor program
d
MELD score takes into account three factors. Bilirubin, INR and creatinine. Recently MELD Na is also included. Model for end stage Liver Disease (MELD) was initially developed to evaluate three months prognosis in patients undergoing TIPS. It ranges from 6 (3 months survival = 90%) to 40 (3 months survival =7%).
In countries where DDLT is more common MELD Score is used to allot grafts to people in the cadaveric list. More severe is the MELD, earlier is the allotment of cadaveric graft.
Previous history of breast cancer if completely treated is not an contraindication of liver transplant. Portal vein thrombosis was earlier considered a relative contraindication but almost all series have shown similar results in patients with PVT than patients without PVT.
IN portal vein thrombosis, inflow to the new liver can me taken in many ways
a) thrombectomy
b) Jump grafts from Superior mesenteric vein
c) Anastomosis have been done from big collaterals
Active tuberculosis can be managed after transplant.
Modified ATT regimens without INH and Rifampicin are being used. Any kind of active substance abuse alcohol, drugs etc are absolute contraindications for liver transplant because the disease will recur.
