Acute Cerebral Artery Occlusion Following Levantine Viper (<i>Macrovipera lebetina</i>) Bite: Gács Sign in Snakebite

Acute cerebral thrombotic stroke following a viper snakebite is a rare occurrence. There have been a few documented cases of cerebral infarctions resulting from envenomation by various viper species. However, none of these reports have specifically detailed instances of stroke induced by <i>Macrovipera lebetina</i> envenomation or vessel occlusion without concurrent cerebral infarction. In this study, we present a case of middle cerebral artery (MCA) occlusion in a 56-year-old man who was bitten by a <i>Macrovipera</i> or <i>Vipera lebetina</i> snake. The individual experienced a snakebite on his right foot, leading to subsequent seizure activity and loss of consciousness. Non-contrast computed tomography scan of the brain revealed hyperattenuation of the right MCA, indicating clot occlusion within the artery, commonly referred to as hyperdense MCA sign or Gács sign.
