哑铃型生长的椎管内肿瘤由于解剖结构的特殊性，手术切除有一定的难度。本文报告了８例与胸外科联合经椎 管和胸腔Ｉ期切除Ｓ例该类肿瘤。３例位于下颈段，５例位于胸段，８例ＭＲＩ均示椎管外部分突入左侧胸腔。术后病理 报告神经鞘瘤４例、神经纤维瘤３例、神经内分泌癌１例。术后１０ｄ症状减轻，１例神经内分泌癌辅助全身化疗半年，随 访至今已２年，无复发。作者认为联合手术增加了Ｉ期切除该类肿瘤的机会，也有利于减少手术创伤和风险性。
Dumbbell-type growth of spinal canal tumors due to the particularity of anatomy, surgical removal of a certain degree of difficulty. This article reports 8 cases of thoracic surgery combined with spinal and thoracic I resection S cases of this type of tumor. 3 cases were located in the lower cervical segment, 5 cases were located in the thoracic segment, and 8 cases of MRI showed that the external portion of the spinal canal broke into the left side of the thorax. Postoperative pathological reports of nerve sheath tumors in 4 cases, 3 cases of neurofibromas, neuroendocrine carcinoma in 1 case. Symptoms were relieved 10 days after operation and neuroendocrine carcinoma was assisted by one year of systemic chemotherapy for six months. No recurrence was observed after 2 years of follow-up. The authors believe that the joint surgery increased the chance of I resection of such tumors, but also help to reduce the surgical trauma and risk.
