本文报告应用第一台国产CO_2激光显微手术装置,成功地切除了T_(11)～L_2髓内室管膜瘤、C_(3～7)髓内纤维血管脂肪瘤和T_(6～8)髓内星形细胞瘤等3例脊髓髓内肿瘤,均达肿瘤次全切除。术后近期内,3例患者的症状与体征均有改善,表现为自发性疼痛消失,肌力增强和肌张力减低;无激光造成的外加神经系统功能缺失的表现。其中2例,术后核磁共振显示肿瘤基本切除干净。表明激光显微手术具有操纵方便、定位精确、安全易控制、无机械牵拉、对周围组织损伤小和不干扰生物电等优点,增加了肿瘤切除的机会,减轻了术后伤残,提高了患者生存质量。作者对激光显微手术的方法和注意事项也进行了讨论。
This report reports the successful application of the first domestic CO 2 laser microsurgery for the resection of T_ (11) ~ L_2 medullary ependymoma, C_ (3 ~ 7) myelofibroma and T_ (6 ~ 8) Intramedullary astrocytoma and other 3 cases of spinal cord intramedullary tumors, all up to the tumor subtotal resection. In the immediate postoperative period, the symptoms and signs of the three patients were improved, with the disappearance of spontaneous pain, enhancement of muscle tone and reduction of muscle tone; and the absence of extraneous nervous system dysfunction caused by laser. In 2 cases, postoperative MRI showed that the tumor was basically resected cleanly. It shows that the laser microsurgery has the advantages of convenient manipulation, accurate positioning, safe and easy control, no mechanical pulling, small damage to the surrounding tissue and non-interference with bioelectricity, which increases the chance of tumor resection, reduces postoperative disability and improves Quality of patient’s life. The authors also discussed laser microsurgery methods and precautions.
