The prone position is commonly used in surgical procedures and is known to cause significant hemodynamic changes, particularly a reduction in cardiac output. This study aimed to explore the relationship between intra-abdominal pressure (IAP), airway pressure, and cardiac output during spine surgeries under general anesthesia. ⋯ Airway pressure is a reliable and noninvasive predictor of significant cardiac output reduction in patients undergoing prone position surgery. Monitoring airway pressure may help identify patients at risk for hemodynamic instability during surgery.

Dual-energy computed tomography (DECT) pulmonary angiography can reliably detect cement pulmonary embolisms (CPEs) and parenchymal perfusion defects. This prospective observational study investigated CPEs in asymptomatic patients using DECT. ⋯ CPEs frequently occur following vertebral augmentation, are associated with substantial prevertebral venous leakage, and predominantly occur in the subsegmental pulmonary artery. They do not always cause perfusion defects.
