To determine the role of intraoperative ultrasonography (IOUSG) in the surgical management of patients with intradural spinal tumors.
Twenty-six patients with intradural spinal cord tumors were surgically treated under intraoperative ultrasonographic guidance between January 2007 and May 2011. Guidance with IOUSG was used in 26 patients, of which 14 fourteen had extramedullary and 12 had intramedullary tumors. Intraoperative ultrasound assistance was used to localize each tumor exactly before opening the dura. The extent of tumor resection was verified using axial and sagittal sonographic views. The extent of tumor resection achieved with IOUSG guidance was assessed on postoperative early control MRI sections.
Total tumor resection was achieved in 22 (84%) of 26 cases. All of the residual tumors were typically intramedullary and infiltrative. The sensitivity of IOUSG for the determination of the extent of resection was found to be 92%. Ultrasonography was found to be effective in identification of tumor boundaries and protection of spinal cord vessels. The average time spent for IOUSG assessment was 7 minutes.
Intraoperative ultrasonography is practical, reliable and highly sensitive for spinal cord surgery. It not only enhances surgical orientation, but also reduces morbidity and helps to resect the tumor completely.
确定术中超声检查（IOUSG）在硬脊膜内脊髓肿瘤患者手术治疗中的作用。
2007年1月至2011年5月期间，26例硬脊膜内脊髓肿瘤患者在术中超声引导下接受手术治疗。26例患者使用IOUSG引导，其中14例为髓外肿瘤，12例为髓内肿瘤。在打开硬脑膜之前，术中超声辅助用于精确确定每个肿瘤的位置。使用轴向和矢状面超声图像来验证肿瘤切除范围。在术后早期控制MRI切片上评估在IOUSG引导下实现的肿瘤切除范围。
26例患者中有22例（84%）实现了肿瘤全切。所有残留肿瘤均为典型的髓内浸润性肿瘤。发现IOUSG用于确定切除范围的敏感性为92%。超声检查在识别肿瘤边界和保护脊髓血管方面被发现是有效的。IOUSG评估平均花费时间为7分钟。
术中超声检查在脊髓手术中实用、可靠且高度敏感。它不仅增强了手术定位，还降低了发病率并有助于完全切除肿瘤。
