K Sankaranarayanan, governor of Maharashtra and Goa was admitted to Bombay Hospital, Marine Lines, on Tuesday afternoon after he complained of giddiness.
“After investigation, we identified a block in the carotid artery in his neck,” said Dr BK Goyal, cardiologist at the hospital. The carotid artery is the large artery whose pulse can be felt on both sides of the neck under the jaw and carries blood to the brain and face.
On Wednesday, a team of doctors from the hospital led by Dr Goyal and cardiac surgeon Dr SS Bhattacharya corrected the block by a surgical procedure.
Sankaranarayanan is recuperating in the cardiac intensive care unit of the hospital.
“The cholesterol had got deposited in his internal carotid artery which goes into the brain. Such a blockage can stop blood to the brain and pose the risk of paralysis,” Bhattacharya said.
“However, his condition is quite stable and is likely to get discharged in the next few days,” said Goyal.
Chief minister Prithviraj Chavan was in the hospital while the procedure was still on, said hospital sources.
