Study summary

Viper envenomation constitutes a medical emergency predominantly occurring in rural regions, where specific viper species are endemic, with their distribution influenced by climatic variations. The literature describes numerous complications associated with viper bites, including neurological disturbance, hematological abnormalities, and irreversible renal failure.

We report the case of a 65-year-old female patient admitted to the intensive care unit for viper envenomation characterized by extensive local edema. Diagnostic investigations, including laboratory tests and imaging studies, revealed the presence of a bilateral pulmonary embolism. The patient was subsequently treated with antivenom therapy, followed by initiation of low molecular weight heparin. Despite the recognized high risk of viper envenomation described in the literature, the patient experienced an uncomplicated clinical course and was discharged in stable condition with no further complications.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 6, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
