Percutaneous biopsy under computed tomography (CT) guidance is a standard technique to obtain a definitive diagnosis when spinal tumors, metastases or infections are suspected. However, specimens obtained using a needle are sometimes inadequate for correct diagnosis. This report describes a unique biopsy technique which is C-arm free O-arm navigated using microforceps. This has not been previously described as a biopsy procedure.
A 74-year-old man with T1 vertebra pathology was referred to our hospital with muscle weakness of the right hand, clumsiness and cervicothoracic pain. CT-guided biopsy was performed, but histopathological diagnosis could not be obtained due to insufficient tissue. The patient then underwent biopsy under O-arm navigation, so we could obtain sufficient tissue and small cell carcinoma was diagnosed on histopathological examination. A patient later received chemotherapy and radiation.
C-arm free O-arm navigated biopsy is an effective technique for obtaining sufficient material from spine pathologies. Tissue from an exact pathological site can be obtained with 3-D images. This new O-arm navigation biopsy may provide an alternative to repeat CT-guided or open biopsy.
当怀疑存在脊柱肿瘤、转移瘤或感染时，计算机断层扫描（CT）引导下的经皮活检是获得明确诊断的标准技术。然而，使用针获取的标本有时不足以进行正确诊断。本报告描述了一种独特的活检技术，即使用微型钳在无C形臂的O形臂引导下进行活检。此前尚未将其描述为一种活检程序。
一名患有T1椎体病变的74岁男性因右手肌肉无力、笨拙及颈胸段疼痛被转诊至我院。进行了CT引导下活检，但由于组织不足未能获得组织病理学诊断。该患者随后接受了O形臂引导下的活检，从而获得了足够的组织，组织病理学检查诊断为小细胞癌。该患者随后接受了化疗和放疗。
无C形臂的O形臂引导下活检是从脊柱病变中获取足够材料的有效技术。借助三维图像可从确切的病理部位获取组织。这种新的O形臂引导下活检可能为重复CT引导下活检或开放活检提供一种替代方法。
