Hémorragie cérébro-méningée secondaire à une envenimation par morsure de serpent : à propos de deux cas au Centre Hospitalier Universitaire Sourô Sanou de Bobo-Dioulasso, Burkina Faso

BACKGROUND: Envenomation by snakebite is a public health problem in developing countries. Neurovascular complications are uncommon. We report two cases of hemorrhagic stroke at the Sourô Sanou Teaching Hospital in Bobo-Dioulasso, which complicate an envenomation. CLINICAL DESCRIPTION: The first patient was a 60-year-old woman with no history, who had been admitted 2 hours after snakebite for gingivorrhagia and consciousness disorders. Clinical examination found coma (GCS 7/15) and tetraparesis. The second patient was a 50-year-old woman with no history, who had been admitted one week after snakebite with digestive bleeding. Clinical examination found right hemiplegia and meningeal syndrome. Both patients presented hemorrhagic stroke on brain CT-scan but hemostasis assessment was normal. They received polyvalent antivenom and symptomatic treatment. The outcome was favorable for survival but with sequelae like tetraparesis for first patient and hemiparesis for second patient. DISCUSSION - CONCLUSION: The hemorrhagic strokes are rare complications of snake envenomation. Venomous toxins can directly lead to the rupture of intracranial vessels apart of abnormalities of hemostasis. However, the morbidity and mortality related to envenomation by snake bite remains high in our environment.
