Veteran actor Soumitra Chatterjee underwent his first plasmapheresis procedure on Thursday (November 12). Doctors treating the veteran actor said late in the night that he was running fever but was stable.

Dr Arindam Kar said, “The first episode of plasmapheresis was done on 85- year-old Soumitra Chatterjee and it went off well, with no external bleeding. Though there was a little bit of drop in blood pressure that was easily corrected and, in the afternoon, we had repeat CT scan which didn't show any abnormalities. He is stable and his blood pressure is now fine.”

However, Soumitra Chatterjee’s neurological function, which is the main concern of the doctors, has not improved yet.
