Compton E, et al. - In this retrospective cohort study, data were investigated to study the relationship between perioperative invasive vascular catheter placement (independent of comorbid conditions) and the risk of postoperative infection in lumbar spine surgery. Researchers observed an overall surgical site infection (SSI) rate of 3.2% within 1 month and 4.5% within 3 months, overall vertebral osteomyelitis rate of 0.82%–0.83% within 1 year, and overall incision and drainage (I&D) rate of 2.8% within 6 months. They noted a significant correlation between perioperative invasive vascular catheterization and an increased risk of postoperative infections in lumbar spine surgery.
