Snake Bite and Radiology
Discussion-Local manifestations of snake bite are soft-tissue swelling from edema, necrosis, and hemorrhage. Common long-term sequelae of envenomation is soft-tissue atrophy distal to the bite, particularly in the digits.-Systemic signs and symptoms after a venomous snake bite are due to anticoagulant/procoagulant activity or neurotoxicity. Cerebral hypoxia can occur due to hypotensive shock that may accompany some snake bite envenomations. Neuromuscular disorders with damage of the peripheral nervous system can with blockage of synaptic transmission, at either presynaptic or postsynaptic levels.Common neurological symptoms are ptosis , ophthalmoplegia, limb weakness , respiratory failure, palatal weakness and neck muscle weakness.Cerebrovascular complications are –- ischaemic strokes in various arterial territories,- haemorrhagic stroke including multiple lobar haemorrhages with or without ventricular extension,- haemorrhages in subarachnoid and subdural spaces,- cerebellar haemorrhage, epidural haematoma,- optic neuritis,- delayed cerebellar ataxia,- disseminated encepha...
