Heparin necrosis is a condition that can occur as a result of heparin therapy. It is characterized by the development of painful, necrotic skin lesions at the site of heparin injections. The condition is relatively rare, but can be serious if not treated promptly.
Causes[edit]
Heparin necrosis is caused by the administration of heparin, a medication used to prevent and treat blood clots. The exact mechanism by which heparin causes necrosis is not fully understood, but it is thought to involve an immune-mediated response.
Symptoms[edit]
The primary symptom of heparin necrosis is the development of painful, necrotic skin lesions at the site of heparin injections. These lesions typically appear within a few days of starting heparin therapy. Other symptoms can include fever, chills, and a general feeling of being unwell.
Diagnosis[edit]
Diagnosis of heparin necrosis is primarily based on the presence of characteristic skin lesions in a patient receiving heparin therapy. Laboratory tests may be used to confirm the diagnosis and rule out other potential causes of the symptoms.
Treatment[edit]
Treatment for heparin necrosis involves discontinuing heparin therapy and starting an alternative anticoagulant. In severe cases, surgical debridement of the necrotic tissue may be necessary.
Prevention[edit]
Prevention of heparin necrosis involves careful monitoring of patients receiving heparin therapy, particularly those at high risk of developing the condition. This includes patients with a history of heparin-induced thrombocytopenia, a condition that can increase the risk of heparin necrosis.
