Spontaneous Heparin-Induced Thrombocytopenia Following Orthopedic Surgery.

Heparin-induced thrombocytopenia (HIT) is a life-threatening complication most commonly associated with exposure to heparin. Timely recognition of suspected HIT is vital, as early intervention is associated with improved outcomes and a decreased mortality rate. Spontaneous HIT is a rare form that occurs in the absence of heparin exposure. Here, we report the case of an 83-year-old patient diagnosed with spontaneous HIT after undergoing knee replacement surgery.
