Snake envenomation causes significant mortality and morbidity. Viper bite usually present with local cellulites, renal
failure and bleeding disorders. Thrombotic manifestation of snake bite is rarely reported and early administration of
Anti-Snake Venom Serum (ASV) also reduces the risk of thrombotic complications. Cerebral infarction in case of...

Snakebite is an emergency which causes local symptoms such as pain and edema around the bite. Systemic symptoms may also develop, such as dizziness or renal failure, and may even cause death. The purpose of this research was to assess the validity and safety of snakebite protocol for surgery when treating snakebite patients.

Introduction: Cerebral venous sinus thrombosis (CVST) is a rare but highly fatal neurological condition mostly caused by prothrombotic conditions like antiphospholipid syndrome, factor V Leiden, and G20210A prothrombin polymorphism. Snake bites are a rare cause of cerebral venous sinus thrombosis that must be recognized and treated promptly to improve survival.
Case Presentation: We present a case of a 25-year-old male who developed headaches and seizures following a Viper snake bite. The diagnosis was made based on a magnetic resonance venogram (MRV) showing transverse sinus thrombosis with sigmoid sinus stenosis. Initially, the patient was treated with antivenom and supportive treatment for disseminated intravascular coagulation (DIC). After the diagnosis of CVST, the patient was treated with rivaroxaban and levetiracetam. The patient improved within 1 week of treatment and was advised to follow up in 3 months.
Conclusion: A high index of suspicion for cerebral venous sinus thrombosis is required if the patient presents with headaches, seizures, or abnormal vision following a snake bite. Early diagnosis and management can prevent further neurological damage.
Russel’s viper (Daboia russelii) is a highly venomous snake erratically distributed in the South Asia and the Russell’s viper (RV) is responsible for 30–40% of the snake bites in Sri Lanka. Common clinical manifestations of RV bite are platelet dysfunction and coagulopathy, neurotoxicity, haemolysis, rabdomyolysis, nephrotoxicity etc. However increased coagulopathy has been rarely reported. Early NCCT brain should be arranged if a patient is becoming drowsy following RV bite in order to identify haemorrhage or cerebral infarction and oedema and intervened early. We report a rare case of a 42 year old lady who became drowsy following a RV bite where she was found to have a complete right hemispheric infarction with midline shift.
Background:
Snake envenomation is associated with serious complications including infections, bleeding and, in rare occasions, thrombosis. Previous work by our group examined the association of snakebite and acute myocardial infarction. In this systematic review we aim to assess the clinical characteristics and outcomes of acute cerebrovascular accidents that are reported to be extremely rare complications of snake envenomation.
Methods:
We performed a literature search for reports on stroke associated with snake envenomation between Jan 1995 to Oct 2018, and summarized their characteristics.
Results:
Eighty-three published cases were reviewed. 66.3% of the cases were younger than 50 years of age. The mean time for the onset of the symptoms is 23.8±10.9 hours after exposure. 77.1% of the cases found to have ischemic stroke, 20.5% with intra-cranial hemorrhage and both infarction and hemorrhage in 2.4%. Mortality was reported in 16.9% with mean time between onset of the symptoms and death is 4.2 days.
Conclusion:
Stroke secondary to snake envenomation is a rare but serious complication. Once stroke is suspected, initiating appropriate management is crucial in reducing morbidity and mortality associated with this potentially fatal complication of snake envenomation.
