A resident of Mumbai, Mehra was today declared the oldest recipient of living donor liver transplant who is now leading a normal life.
He underwent a successful liver transplant after his daughter donated a portion of her liver.
"In today's fast changing world age remains no criteria for getting liver transplant done.
We have done successful liver transplants on 240 patients at Medanta in last one year on patients of 3 months of age to 78 years," Dr A Soin, chairman , Institute of Liver Transplant and Regenerative Medicine, Medanta Hospital said.
He said Mehra is the oldest liver transplant recipient in India and has proved that age really has no bearing on the outcome of any surgery if one is medically fit.
"We have more than 70 senior citizens who have undergone successful liver transplant and are leading normal lives. I wish all grandparents best of health and many more years of healthy life," he said.
J R Verma, a Delhi resident, underwent a total knee replacement at the age of 79 years in 1999 and four months back he underwent revision surgery at the age of 91 years after a fall.
"He is leading as active a life as any young 91-years -old does," Dr Ashok Rajgopal, Chairman, Institute of Bone and Joint Replacement, said.
He said, "while the common belief is that artificial knee replacement surgery should not be done on the very young or the very old and that it has a very limited life span, the truth is quite the opposite. Age really has no bearing on the outcome of this surgery."
Doctors also cited the case 82-year-old Roop Singh who underwent a successful graft replacement for a leaking aortic aneurysm, 72-year-old Birender Nihal Singh and Ravinder Singh (68) who were successfully operated for cardiac bypass surgery.
"Today, age has really no bearing on the outcome of various surgeries we perform," Dr Naresh Trehan, chairman and managing director, Medanta, said.
