CT引导下经皮肺穿刺活检并发症的相关因素分析

目的:分析引起CT引导下经皮肺穿刺活检并发症发生的相关因素.方法:选取2003年10月～2005年9月CT引导下肺穿刺活检的病例284例,分析穿刺并发症的发生与性别、年龄、病灶大小、深度、病灶周围有无肺气肿、穿刺次数、穿刺针粗细等的关系,并进行统计分析.结果:共发生气胸26例,出血(包括肺内出血和针道出血)48例.并发症的发生与病灶大小、深度、病灶周围有无肺气肿、穿刺次数、穿刺针粗细及年龄有关(P＜0.05).结论:CT引导下经皮肺穿刺活检常见并发症有气胸和出血.病灶大小、深度、病灶周围肺气肿、穿刺次数、穿刺针粗细以及年龄是肺穿刺活检并发症的相关因素.

Analysis of Interrelated Factors of Complications in CT Guided Percutaneous Biopsy

Objective:To analyse the interrelated factors of complications in CT guided percutaneous biopsy.Methods:284 percutaneous biopsies were done for pulmonary lesions from 2003 October to 2005 September.We analysed the relations between complications and patients' sexes,ages,sizes of lesions,depth,and emphysema around lesions with statistics.Results:There occurred 26 cases of pneumothorax and 48 cases of bleedings (including those from the lungs and the paths of needles).Complications were related to the lesion's size,depth,emphysema around the lesion,puncture numbers,sizes of needles and patients' ages(P<0.05).Conclusion:Common complications in CT guided biopsy include pneumothorax and bleeding.The correlated factors influencing complications of biopsy are the lesion's size and depth,emphysema around the lesion,puncture numbers,the size of the needle as well as patients' ages.
