Spinal cord complications are rarely encountered in elective pediatric surgery. We present a patient who became paraplegic after resection of a chest wall tumor. After neoadjuvant radio- and chemotherapy, a 10-year-old girl with primitive neuroectodermal tumor (PNET) of the right chest underwent a right chest wall resection. Ribs #3, 4, 5, and 6 were resected en masse with a pulmonary wedge resection of right upper and middle lobes. To obtain clear margins, the ribs were disarticulated from the vertebral column. Significant bleeding arose when the fourth rib was detached. Presuming an intercostal vessel bleed, the area was packed with surgicel with resolution of the bleeding. The patient was kept sedated and ventilated in the PICU. The next day, she complained of paresis of her lower extremities. MRI revealed compression of the spinal cord at the T4 level. Emergency decompression and laminectomy was performed. Blood clot and surgicel were found in the area of the spinal canal. Giant epidural veins were encountered as well, again with massive bleeding. The patient never regained neurological function below the insult to the cord. Despite negative margins and ongoing chemo- and radiotherapy, her tumor recurred and she died to her disease less than 1 year later. Chest wall tumors arising near the spinal canal may be associated with enlarged Batson's plexus that may hemorrhage during surgical resection. We recommend immediate imaging or prophylactic laminectomy for any concerns of spinal hemorrhage. Patients should also receive regular assessment of neurovitals, despite issues of pain control and sedation.
脊髓并发症在小儿择期手术中很少见。我们报告一例在切除胸壁肿瘤后发生截瘫的患者。在新辅助放化疗后,一名患有右胸原始神经外胚层肿瘤(PNET)的10岁女孩接受了右胸壁切除术。第3、4、5和6肋骨整块切除,并对右上叶和中叶进行肺楔形切除术。为了获得切缘阴性,肋骨从脊柱上离断。在分离第四肋骨时出现大量出血。推测为肋间血管出血,该区域用外科止血纱布填塞后出血停止。患者在儿科重症监护病房(PICU)接受镇静和机械通气。第二天,她主诉下肢无力。磁共振成像(MRI)显示T4水平脊髓受压。遂进行了急诊减压和椎板切除术。在椎管区域发现血凝块和外科止血纱布。同时还发现巨大的硬膜外静脉,再次出现大量出血。患者脊髓损伤以下的神经功能未恢复。尽管切缘阴性且持续进行放化疗,她的肿瘤仍复发,不到1年后因疾病死亡。椎管附近出现的胸壁肿瘤可能与扩大的巴特森静脉丛有关,在手术切除过程中可能出血。对于任何脊髓出血的疑虑,我们建议立即进行影像学检查或预防性椎板切除术。尽管存在疼痛控制和镇静问题,患者也应定期接受神经生命体征评估。
