RESUMO
BACKGROUND: Iatrogenic lumbar pseudomeningoceles are an uncommon complication of lumbar spinal surgeries. This pathology is an extradural, encapsulated, and cerebrospinal fluid collection which develops as a consequence of an inadvertent, unrepaired dural tear. If a pseudomeningocele grows beyond 8 cm in length, it may be classified as "giant." CASE DESCRIPTION: Two adult females with giant pseudomeningoceles due to remote lumbar laminectomy were presented. Both patients were surgically managed. CONCLUSION: Iatrogenic lumbar giant pseudomeningocele is rare. Notably, their surgical management is similar to that utilized to treat routine pseudomeningoceles.
RESUMO
BACKGROUND: Intraoperative tension pneumothorax (TPT) is extremely rare in spinal surgery overall and particularly in extensive deformity procedures. Here, we report a TPT occurring in conjunction with posterior vertebral column resection (pVCR) for the treatment of congenital scoliosis. CASE DESCRIPTION: A 12-year-old female undergoing congenital thoracic scoliosis surgery (e.g., pVCR) developed abrupt intraoperative increases in airway pressure and compromised hemodynamics that led to a TPT. This was directly attributed to an inadvertent pleural tear. Temporary drainage of the accumulated air was accomplished with a urethral catheter inserted directly into the pleural cavity. This was later supplemented with a standard chest tube. The child quickly improved and was routinely discharged a few days later. CONCLUSION: In patients undergoing pVCR, if the surgical team is faced with unexplained hemodynamic instability and increased airway resistance, a TPT should be strongly suspected and appropriately managed.
