A close relative (53yrs, female, hypertensive, no history of diabetes and tobacco) was admitted in ICU for 15 days due to severe viral pneumonia/ARDS. The pneumonia is now almost cured, but the patient has developed these gangrene like dead cells on her fingers. Most likely cause is a thrombus developed in wrist due to pic line used during pneumonia treatment. The vascular surgeons took a call to not take surgical intervention at that time due to severity of lung damage and started heparin. She is out of ICU for last 1 week, but still getting fever multiple times everyday. All the blood tests for bacterial infections are coming negative. The doctors at the hospital are saying that they will wait for sometime and then probably amputate the affected area. Is there any way to heal this without surgery? Also, could gangrene be cause of fever? Edit: I have attached the image of Doppler report. Also heparin is going on for last 20 days.
