Life threatening intracerebral haemorrhage following saw- scaled viper (Echis carinatus) envenoming-authenticated case report from Sri Lanka

BACKGROUND: Echis carinatus (Saw scaled viper {SSV}) is a venomous snake found in the parts of Middle East and Central Asia. SSV envenoming is characterized by local swelling and coagulopathy. Various bleeding manifestations are commonly seen with SSV envenoming. In contrast to other part of Asia, saw scale viper envenoming has not been reported to cause life threatening haemorrhagic manifestations in Sri Lanka. CASE PRESENTATION: We report a 19 years old healthy boy who developed massive left temporo-parietal intra cerebral haemorrhage following Echis carinatus (Saw scaled viper) bite in Sri Lanka. CONCLUSION: Although subspecies of SSV in Sri Lanka is regarded as a ‘non lethal venomous snake’, the occurrence of rare potentially fatal complications such as intracerebral haemorrhage should be considered in their management. This case report is intended to bring the awareness of this fatal complication of SSV envenoming in Sri Lanka.
