Reversible lower limb deep vein thrombosis following haemotoxic snakebite--a case report.
Abstract
Haemotoxic snakebite, presenting with coagulopathy and bleeding manifestations, is quite common. Thrombotic manifestations are infrequently observed. We describe the unusual case of a young male who developed deep vein thrombosis (DVT) of the left lower limb following snakebite, despite an ongoing coagulopathy. Investigations revealed leucocytosis, prolonged 20-minute whole blood clotting time (20’WBCT), prolonged prothrombin time (PT), and activated partial thromboplastin time (aPTT). Doppler study revealed thrombosis of common femoral vein, superficial femoral, and profunda femoris veins. The patient underwent 2 fasciotomies and received anticoagulation after which patency of the veins was restored. Doppler sonographic imaging in patients with haemotoxic snakebite who present with increasing local swelling may assist with early anticoagulation therapy that has a potential to be limb-saving.
