RESUMO
Bothrops atrox envenomations in the Brazilian Amazon are responsible for a number of local and systemic effects. Among these, stroke presents the worst prognosis for the patient since it may evolve into disabilities and/or premature death. This complication is caused by coagulation disorders and generates hemorrhagic and thrombotic conditions. This study presents a case report of a 54-year-old female patient who presented extensive cerebral ischemia after a B. atrox envenomation that occurred in the state of Amazonas, Brazil. The patient was hospitalized for 102 days, which included a stay in the intensive care unit. Clinical and laboratory findings indicated a thrombogenic coagulopathy. On discharge, the patient had no verbal response, partial motor response, and right hemiplegia. The assessment carried out four years after discharge evidenced incapacitation, global aphasia and bilateral lower and upper limbs showed hypotrophy with a global decrease in strength. Ischemic stroke is a possible complication of B. atrox snakebites even after antivenom treatment, with the potential to cause debilitating long-term consequences.
