About The Transplant

Liver Transplant
Liver Transplant is a surgical procedure to replace a diseased or a non-functioning liver with a healthy liver from a donor. Liver Transplant is a last resort measure and is undertaken only when all other treatment options have been exhausted. The liver performs more than 500 vital functions in a human body, and it is impossible for any mechanical device to replicate its functions that are why in the case of liver failure, transplantation is the only viable option to save the life of the patient.

Indications for Liver Transplantation
Liver failure can happen all of a sudden due to certain medical complications or could be a result of some long-term ailment that had been diagnosed too late resulting in Liver failure. Patients who are candidates for liver transplantation are suffering from one or more of the following conditions: -

  • Acute Liver Failure
    This condition is also known as Fulminant Hepatic Failure, where a normal and healthy liver suffers sudden massive injury leading to liver insufficiency. There are various causes that can lead to this condition like viral infections, ingestion of toxic mushrooms or drug reactions. Patients with Acute Liver Failure may die within days if they do not receive a transplant.  They are always a priority for a liver transplantation.

     
  • Chronic Liver Disease
    Liver possesses an amazing capability to repair and heal from injuries itself. However, due to repeated injury and repair procedure, leads to Liver Cirrhosis i.e. permanent scarring. Once the liver reaches this stage, it cannot heal itself. Cirrhosis stops the liver from functioning properly, and though medicines might control the symptoms, transplantation is the only permanent cure. 

     
  • Alcoholic Liver Disease
    Excessive consumption of alcohol over an extended period of time leads to permanent and irreversible damage to the liver. In such cases, Liver Transplantation is the only way out to save the patients life. A six month complete abstinence period is mandatory before proceeding with the transplant, to ensure the success of the transplant.

     
  • Viral Hepatitis

It prevents the liver from functioning normally with worsening symptoms every day.  Due to the complexity of the disease, Liver transplantation is the only therapy to treat it.

     
  • Metabolic Liver Disease
    It is a condition in which due to fat accumulation in the liver cells there is severe inflammation that leads to scarring of the liver. This condition is also called Non-alcoholic steatohepatitis. Only Transplantation provides a permanent cure for the disease.

     
  • Vascular Disorders
    A Vascular disorder like Budd-Chiari syndrome leads to clotting in hepatic veins which result in reduced blood flow through the liver. Transplantation is the only way to treat this ailment.
