Case in brief
A patient presented with a MacMahon viper bite, experiencing significant local envenomation, hypotension, and syncope. Laboratory tests showed rapid thrombocytopenia and impaired haemostatic function. Despite the acute phase symptoms, no bleeding occurred, and thus no transfusion or coagulation factors were administered. The patient's thrombocytopenia resolved spontaneously within 8 days.
Diagnostic / clinical pearl
Clinicians should be aware that MacMahon viper bites can lead to toxin-induced coagulopathy, characterized by rapid thrombocytopenia and impaired haemostasis, without immediate bleeding.
Why it matters
Understanding the specific effects of MacMahon viper venom is crucial for appropriate management, especially in settings with limited resources and antivenom availability.
