A Case of Cobra Bite Complicated with Basilar Artery Occlusion.

Abstract

Snakebite is one of the most common complaints related to wilderness medicine. Venomous snakebite manifestation is divided into local and systemic envenomation. For the Elapidae group, the most feared complication is respiratory muscle paralysis due to neurotransmitter malfunction at the neuromuscular junction level which leads to respiratory insufficiency. However, there is a lack of evidence or case report incidence to suggest that it can potentially associate with the development of stroke disorder. We present a rare case of massive posterior circulation infarct in a middle-aged gentleman following a cobra bite. He was brought to our center few hours later following the bite and antivenom was administered. He improved shortly after receiving it. However, he had an abrupt drop in his conscious level several hours later. Noncontrast-enhanced computed tomography (NCCT) brain was performed immediately, but stroke disorder was excluded prematurely. Repeated NCCT imaging which was done 12 h apart showed massive posterior circulation infarction with hydrocephalus. He succumbed to death 3 days later. Given its rarity, the evolution of his clinical condition warrants clinician's early suspicion of potential stroke-related complications that can occur following a cobra bite.
