Peter Sfameni, 55, stopped taking Warfarin before he underwent a colonoscopy and chose not to resume taking the medication after the procedure. He developed lower back pain, fatigue and weight loss, which prompted a trip to Rhode Island Hospital’s emergency room. He was admitted to the hospital, underwent a bone marrow biopsy and was scheduled for a lymph node biopsy. He was discharged with instructions not to take his blood thinners until a week after the upcoming lymph node biopsy.
Sfameni developed severe blood clots in his legs and lungs before the date of the biopsy. Sfameni returned to the hospital where doctors diagnosed gangrene in his right leg, which required an above-the-knee amputation.
Sfameni spent five months in the hospital, followed by four months in rehabilitation. He now uses a prosthesis and experiences constant phantom pain, anxiety and depression.
