Study DesignRetrospective cohort study.ObjectiveTo investigate the impact of age on the incidence of vascular complications in patients undergoing anterior lumbar approach surgery.BackgroundAnterior approach lumbar spinal surgery may facilitate the use of intervertebral devices with larger endplate coverage and increased lordosis. Despite the advantages of this approach, risks related to vascular injury in older patients have been described in the literature.Patients And MethodsIn total, 751 consecutive patients with degenerative spinal pathology who underwent stand-alone anterior lumbar interbody fusion (ALIF), ALIF combined with posterior fusion and/or instrumentation (360), total disc replacement, or hybrid procedures (ALIF and total disc replacement) were included. Data collected included general patient descriptive data, surgery details, intraoperative vascular injury, and postoperative vascular complications (deep vein thrombosis and/or pulmonary embolism). Rates of vascular complications were compared across age groups. In addition, the mean age of patients was compared between those with versus without vascular complications.ResultsOverall mean age was 50.4 years (range: 20-83 yr). The mean estimated blood loss was 91.3 mL (range: 10-2800 mL). A total of 15 patients, 2.0%, had vascular complications. There were 10 cases (1.3%) of intraoperative injury to iliac arteries or iliolumbar veins (mean blood loss was 721 mL, and all were repaired intraoperatively). Postoperatively, 6 patients (0.8%) developed deep vein thrombosis and/or pulmonary embolism (one patient had both). With respect to age, there were no significant differences in rates of intraoperative, postoperative, or combined vascular complication rates across the age group ( P > 0.38). In addition, there were no statistically significant differences in the mean ages of patients with versus those without vascular complications ( P > 0.17).ConclusionOverall incidence of vascular complications was 2.0%. No relationship between vascular complications and age was demonstrated. These data suggest that increased age may not necessarily be an absolute contraindication for anterior lumbar approach surgery.Level Of EvidenceLevel III.Copyright © 2024 Wolters Kluwer Health, Inc.
