Abstract

Air embolism (AE) is a subtype of embolism, caused by the entry of air into the vascular system. It is a predominantly iatrogenic complication, and its symptomatic form is severe, although uncommon. In some cases, a venous thrombi may pass into the arterial system through a venous-arterial shunt, characterizing a paradoxical embolism. Here, we describe the case of a previously healthy 44-year-old female who underwent cauda equina decompression and lumbar epidural abscess drainage. The patient suffered a paradoxical AE intraoperatively and died after 4 days. The occurrence of AE in lumbar spine surgeries in the prone position is rare, but the surgical team must be attentive to its clinical signs and quickly institute initial management when necessary.

Resumo

A embolia gasosa (EG) é um subtipo de embolia, causada pela entrada de ar no sistema vascular. É uma complicação predominantemente iatrogênica e sua forma sintomática é grave, embora incomum. Em alguns casos, um trombo venoso pode migrar para o sistema arterial através de um shunt venoso-arterial, caracterizando uma embolia paradoxal. Aqui, descrevemos o caso de uma mulher de 44 anos, previamente saudável, submetida a descompressão da cauda equina e drenagem de abscesso peridural lombar. A paciente sofreu uma EG paradoxal no intraoperatório e morreu 4 dias depois. A ocorrência de EG em cirurgias da coluna lombar em posição prona é rara, mas a equipe cirúrgica deve estar atenta aos seus sinais clínicos e, quando necessário, instituir o manejo inicial rapidamente.
