Overview
Natural History
Complications
Complications of HIT are most thrombotic in nature. These can be quite devastating, which high morbidity and mortality. Venous thrombosis includes deep vein thrombosis (DVT) and pulmonary embolism (PE). Arterial thrombosis includes stroke and acute limb ischemia.
Venous thrombosis
- Deep vein thrombosis
- Pulmonary embolism[1]
- Post-phlebitis syndrome: This can occur after DVT and results in inflammation of the leg and its veins due to chronic occlusion.
- Cerebral venous sinus thrombosis
Arterial thrombosis
- Acute limb ischemia[1]: This can sometimes require limb amputation to prevent further tissue damage and sepsis from the thrombotic arm or leg.
- Stroke[1]
- Myocardial infarction: This is characterized by myocyte death due to ischemic injury from coronary artery occlusion. It is also known more commonly as a heart attack.
- Skin necrosis[1]
DIC
