胸部肿瘤定位穿刺技术的临床应用

目的:探讨 CT引导下胸部肿瘤定位穿刺技术临床应用价值。方法 :2 0 0 1年 3月～ 2 0 0 3年 8月经 CT引导穿刺活检的 32例胸部占位性病变。肺周围性肿块 8例 ,纵隔及肺中央性肿块 2 0例 ,胸水疑胸膜转移 4例。 16例患者曾在纤维支气管镜下做活检 1～ 2次 ,但均未确诊。CT定位后用 16～ 18G切割式穿刺枪从前或后胸壁避开重要脏器进针 ,穿刺 1～ 3次 ,送组织学或加细胞学病理检查。结果 :2 8例明确诊断 ,阳性率 81.82 % (2 8/ 32 ) ,1例气胸 ,2例少量出血 ,其余病例未发生严重并发症。 结论 :CT引导胸部肿瘤定位穿刺技术对纤维支气管镜检查阴性的胸部占位性病变有较重要的临床价值 ,值得进一步推广应用。

Clinical application of CT-guided biopsy in thoracic tumor

Objective: To probe the value of clinical application of CT-guided biopsy in thoracic tumor. Methods: Thirty-two patients with thoracic tumor were reviewad between Match, 2001-April, 2003. There were 8 cases with peripheral mass of lung, 20 with central and mediastinal mass, and 4 with pleura metastasis. Among them, 16 patients had undergone bronchoscopy but without pathological result. After CT positioning, 16-18G BARD puncturable gun were used to penetrate anterior or posterior chest wall and kept clear of important organs. Histology and cytology detection were done after 1-3 times puncture. Results: Twenty-eight cases were diagnosed definitely with positive rate 81.82%(28/32). 1 case with peumothorax ; two with a little bit bleeding; no other serious complications. Conclusion: CT-guided biopsy deserved to further study, especially in patients without positive result of bronchoscopy.
