CT介导FNB在眼眶的应用研究

Orbital Fine-needle Biopsy with CT Guidance

对２６例单侧眶内肿块患者行ＣＴ介导细针穿刺活检术（Ｆｉｎｅ－ｎｅｅｄｌｅｂｉｏｐｓｙ，简称ＦＮＢ）。穿刺针分别采用普通腰穿针、秦氏多孔针或槽式针，于ＣＴ导引下进入肿块。全部病例均获得正确的细胞学诊断。若在操作者技术熟练和病理科与ＣＴ室密切配合的情况下，选用秦氏槽式针可以增加获取组织学诊断的机会。本组病例均未发生并发症。笔者认为本法适用于诊断各种类型的眼眶肿块，特别是对突眼病变的术前定性有重要价值。

patients with unilateral orbital masses underwent fine needle biopsy(FNB)guided by CT.Theneedles, including common needles and Qin′s multi-aperture or guttered needles, were introduced into themasses following the pathway which was guided by CT, An accurate cytologic diagnosis could be reached in allcases.However, with a proficient operator as a close collaboration between Pathology Department and CTRoom, employing Qin′s guttered-needle may increase the chance of getting the histologic diagnosissignificantly.No complications of any kind were observed in our cases.Our report indicated that this techniqueis applicable for all kinds of orbital mass lesions, and is particularly of great value to define the lesions causingexophthalmos before operation.
