A 74-year-old man was referred to our hospital for a close examination of a mediastinal mass. Contrast-enhanced CT showed a middle mediastinal tumor. We planned to perform a CT-guided percutaneous needle biopsy of the tumor using a retroaortic paravertebral approach to avoid transpulmonary puncture. A coaxial blunt-tip needle with a side hole was used to create space in the mediastinum and avoid azygos vein injury. After injecting normal saline, a blunt-tip needle was advanced through the space between the aorta and the vertebral body to the anterior surface of the tumor, and tissue was obtained. The patient was discharged the following day with no complications. For percutaneous middle mediastinal tumor biopsy, the retroaortic paravertebral approach may be a safe, effective route.
一名74岁男性因纵隔肿物需进一步检查被转诊至我院。增强CT显示为中纵隔肿瘤。我们计划采用主动脉后椎旁入路对肿瘤进行CT引导下经皮穿刺活检，以避免经肺穿刺。使用带有侧孔的同轴钝头针在纵隔内制造空间并避免奇静脉损伤。注入生理盐水后，将钝头针经主动脉与椎体之间的间隙推进至肿瘤前表面，获取组织。患者次日出院，无并发症。对于经皮中纵隔肿瘤活检，主动脉后椎旁入路可能是一种安全、有效的途径。
