CT引导下经皮肺穿刺并发症的影响因素

Risk factors of complications induced by CT-guided percutaneous lung biopsy

目的探讨CT引导下经皮肺穿刺常见并发症的影响因素。方法回顾性分析我院行CT引导下经皮肺穿刺的138例患者,分析临床特征,评估并发症的影响因素。结果 CT引导下经皮肺穿刺患者中,23例发生气胸,发生率为16.67%;34例发生出血,发生率为:24.64%。基础肺功能、肿块直径、位置及病变类型可显著增加气胸的风险;肿块直径、活检枪型号则增加出血的风险。结论 CT引导下经皮肺穿刺安全性好。气胸的影响因素包括:患者的基础肺功能、肿块直径、位置及病变类型;出血的影响因素包括:肿块直径及活检枪型号。

Objective To explore the risk factors of the complications induced by CT-guided percutaneous lung biopsy. Methods The clinical data of 138 cases of CT-guided pcrcutaneous lung biopsy were collected to ana lyze their clinical characteristics and the risk factors of the complications. Results There were 23 cases of pneumo thorax （ 16.67% ） and 34 cases of bleeding （24. 64% ）. The basic lung function of patients, and the diameter, posi tion and pathological type of the mass increased the risk of pneumothorax. The risk of bleeding were significantly in creased with the diameter of the mass and the type of automatic biopsy gun. Conclusion CT-guided percutaneous lung biopsy is a safe method. The risk of pneumothorax includes the basic lung function of patients and the diameter, position and pathological type of the mass. And the risk factors of bleeding include the diameter of the mass and the type of automatic biopsy gun.
