Neuroblastic tumors (NBTs) develop from neural crest cells that give rise to the sympathetic nervous system. They include neuroblastomas, ganglioneuroblastomas, and ganglioneuromas. They represent approximately 10% of solid tumors in children under 15 years of age. In 15 to 20% of cases, NBTs are located in the thoracic region. These paravertebral tumors have an extracanal component and some also have an intraspinal component (dumbbell tumors) that can cause spinal cord compression. Surgery for these tumors also exposes the patient to neurological complications. In the thorax, the basi-thoracic location (T9-T12) may be particularly at risk due to the presence of the artery of Adamkiewicz (AKA), which supplies blood to the spinal cord; damage to this artery can result in spinal cord ischemia. To avoid this scenario, some teams recommend performing spinal cord arteriography to identify AKA. However, many centers do not perform arteriography and do not report more postoperative complications. Currently, there is no consensus on the indications for performing preoperative spinal arteriography in patients undergoing surgery for basi-thoracic NBT. This study evaluates the practice in France of preoperative arteriography to identify the AKA among patients undergoing surgery for basi-thoracic neuroblastic tumors and analyzes the incidence of postoperative neurological complications in these patients.
