RESUMO
OBJECTIVES: The objective of this study was to review the outcomes of a multidisciplinary approach to the surgical management of pediatric bone tumors with blood vessel involvement over a 14- year period. METHODS: A retrospective review was conducted of all pediatric bone tumor resections performed with the assistance of vascular surgery at our institution between January 2006 and January 2021. Inclusion criteria for the study included the presence of a vascular surgeon at the operative resection and radiographic evidence of major blood vessel involvement. RESULTS: From 2006 to 2021, 117 patients underwent a bone tumor resection by a single orthopedic surgeon/vascular surgeon team. Sixty were malignant tumors, and 57 were benign. Of the 117 procedures, 5.1% (6/117) required reconstruction of an artery; five in malignant cases and one in benign. No venous reconstructions were undertaken in this study. Ligation of a major artery without reconstruction was performed in 8.8% (5/57) of malignant and 1.7% (1/60) of benign resections. Despite this vessel-sparing approach, microscopic margins were clear in all cases. Local recurrence occurred in a single patient in the malignant group at 61 months. CONCLUSIONS: The ideal management of pediatric bone tumors with major blood vessel involvement remains poorly defined. Our results demonstrate that even in the setting of radiographic evidence of vessel involvement, a multidisciplinary team of vascular and orthopedic surgeons can employ a vessel-sparing approach with minimal blood loss, excellent limb salvage, and minimal local recurrence.
