[Horned-Viper Bite: A Clinical Case and Review of Therapeutic Approach]

Envenomation by the horned viper (Vipera latastei), endemic to the Iberian Peninsula, typically causes local and hematologic toxicity, potentially leading to venom-induced consumption coagulopathy. We report the case of a 39-year-old man bitten on the fourth finger of his left hand. The first dose of antivenom (ViperFav®) was administered 10 hours after the incident, followed by two additional doses due to persistent coagulopathy and transient thrombocytopenia. Hyperbaric oxygen therapy (10 sessions) and a transdermal nitroglycerin patch were used to optimize local perfusion as adjuvant therapies that are still discussed in the medical literature. Clinical evolution was favorable, with preservation of finger viability and progressive laboratory recovery. This case highlights the importance of early antivenom administration, continuous hematologic monitoring, and the potential benefits of integrating adjuvant therapies to prevent necrosis and systemic complications. A multidisciplinary approach enabled full functional recovery without sequelae.
