Samar Chakraborty, a resident of Dumdum, was suffering from diabetes, hypertension and chronic kidney disease.
He was admitted at a hospital in north Kolkata with Intra Cerebral Hemorrhage and had gone into a deep coma, suffering irreversible brain damage in the process, a senior doctor of the hospital said.
Chakraborty was shifted to Apollo Gleneagles Hospitals in the city, where a panel of doctors and the Department of Health, Government of West Bengal, evaluated his condition and declared him brain dead.
"His liver was transplanted to 46-year-old Madhuri Saha, a patient with a known case of autoimmune hepatitis, decompensated cirrhosis, ascites, hepatic encephalopathy and hypersplenism," Dr Rupali Basu, President and CEO-ER, Apollo Hospitals Group, told PTI.
The recipient had been advised a liver transplant and was waiting a suitable donor.
