Abdominal aortic calcification is an independent predictor of perioperative blood loss in posterior spinal fusion surgery – Lumbar Fusion

Day Case Lumbar Fusion Surgery

The study published in the European Spine Journal in 2024 examines the impact of abdominal aortic calcification (AAC) on perioperative blood loss in posterior spinal fusion (PSF) surgeries. The researchers found that AAC, a marker of advanced atherosclerosis, independently predicted an increase in blood loss during PSF procedures. This association highlights the importance of considering AAC as a potential risk factor in spine surgery, in addition to its known association with degenerative spinal conditions and adverse postoperative outcomes. The findings suggest that AAC should be taken into account when assessing and managing perioperative blood loss in patients undergoing PSF

S: This is the first study to identify AAC as an independent predictor of perioperative blood loss in PSF. In addition to its link to degenerative spinal conditions and adverse postoperative outcomes, the relationship between AAC and increased blood loss warrants attention in patients undergoing PSF.

ABSTRACT

OBJECTIVE: Abdominal aortic calcification (AAC), often found incidentally on lateral lumbar radiographs, is increasingly recognized for its association with adverse outcomes in spine surgery. As a marker of advanced atherosclerosis affecting cardiovascular dynamics, this study evaluates AAC’s impact on perioperative blood loss in posterior spinal fusion (PSF).

METHODS: Patients undergoing PSF from March 2016 to July 2023 were included. Estimated blood loss (EBL) and total blood volume (TBV) were calculated. AAC was assessed on lateral lumbar radiographs according to the Kauppila classification. Predictors of the EBL-to-TBV ratio (%EBL/TBV) were examined via univariable and multivariable regression analyses, which adjusted for parameters such as hypertension and aspirin use.

RESULTS: A total of 199 patients (47.2% female) were analyzed. AAC was present in 106 patients (53.3%). AAC independently predicted %EBL/TBV, accounting for an increase in blood loss of 4.46% of TBV (95% CI 1.17-7.74, p = 0.008).

S: This is the first study to identify AAC as an independent predictor of perioperative blood loss in PSF. In addition to its link to degenerative spinal conditions and adverse postoperative outcomes, the relationship between AAC and increased blood loss warrants attention in patients undergoing PSF.
