Posterior cerebral artery embolism following Naja sputatrix snakebite: Unusual case of snakebite envenomation

, , ,

Abstract

Background: Snakebite envenoming can potentially cause a life-threatening condition, including embolic stroke, because of the hemotoxic effect. Hemotoxicity of snakebite venom can affect blood clotting factors, make blood clots,  be carried in brain circulation, and cause neurological deficits.

Case presentation: A 34-year-old man from Bima, West Nusa Tenggara, Indonesia, was bitten by a Naja sputatrix snake. This patient exhibited signs and symptoms of cerebral infarction after he had a snakebite. Cerebral computed tomography angiography resulted in thromboembolic cerebral infarction in the right temporoparietal occipital according to the right posterior cerebral artery (PCA) territory. An anticoagulant was given to reduce the blood coagulation cascade and inhibit thrombin formation.

Conclusion: An embolic stroke because of a snakebite is a rare case. Severe neurological deficit and rapid treatment determine the prognosis.
