 Hi, I am Dr. Ravichan Siddhachari. I am a consultant hepatobiliary and liver transplant surgeon for Manipal Hospital Group, Bangalore. A cute liver failure is a condition when one person who has got a normal liver develops disease and which causes so much damage that he becomes very sick very soon and gets admitted to intensive care unit. And if you don't perform a liver transplant within days, he is going to die. So this is usually due to hepatitis A and E in our country. These viruses cause acute liver damage. Normally 95-98% of patients with hepatitis A or E, they recover spontaneously. Hardly 1-2% of the patients suffer from acute liver failure, wherein the patient gets very sick. And in these conditions you have to perform a liver transplantation to save the life.
