Case Report: Hemothorax in Envenomation by the Viperid Snake Bothrops asper

Bothrops asper, a highly venomous pit viper distributed from Colombia and northwestern Peru in South America to southern Mexico, is responsible for most snake bites in Central America, affecting especially young agricultural workers. A 17-year-old male from a rural area in northern Honduras was admitted at San Francisco Hospital after a B. asper bite that had occurred 3 days earlier. The puncture wounds were located on the first toe of the right foot. On the second day of admission, the patient developed dyspnea. A physical examination revealed hypoventilation of the left lung with dullness on 75% of the left lung. Left pleural effusion, approximately 90%, was observed on the chest X-ray. The patient was diagnosed with hemothorax, and a thoracostomy drained 1,350 mL of serosanguineous fluid, followed by the installation of a wet suction control system (Pleur-evac®). After 10 days, the patient was discharged. This case illustrates the diversity of hemorrhagic manifestations in envenomations by B. asper.
