Perioperative Outcomes Following Pediatric Cranial Vault Remodeling: Are Improvements Possible?

The Pediatric Craniofacial Collaborative Group recently reported pooled perioperative data from 31 North American centers performing open cranial vault remodeling procedures. The authors sought to determine if outcomes were different at a single higher-volume center and if identified, ascertain reasons for any differences and propose strategies for improvement.

A retrospective review was performed of all open pediatric cranial vault procedures performed at our center during the identical 3.25-year period reported by the Collaborative group, including demographic, perioperative management and outcome data, to permit multiple comparative analyses.

The 310 procedures were performed by our center during this time period, compared to 1223 by the combined 31 institutions (median: 29.5 cases/center; interquartile range: 12-54.5). Multiple outcome differences were found: our higher-volume center had a significantly lower overall red blood cell transfusion rate (≤2 years: 7.5 percent vs 91 percent, P <0.001), those requiring transfusions were transfused considerably smaller volumes (≤2 years: 3.8mL/kg vs 45.3 mL/kg, P <0.001), and exposure to ≥3 blood donors was significantly less (none vs 20 percent, P <0.001). There were no mortalities in either group, but almost all matched adverse events were less common at our center. Both the intensive care unit and hospital lengths of stay were significantly shorter at our center (1 vs 2 days, 2 vs 4 days, both P <0.001).

Perioperative outcomes following pediatric craniosynostosis corrections performed at a single higher-volume center compare favorably to median national data. Multiple potential strategies to reduce blood utilization, minimize perioperative complications, and shorten hospitalizations are proposed.
