MSCT激光定位下经皮肺穿刺并发症的影响因素

An analysis of the complications after MSCT laser guided percutaneous lung biopsy

目的:探讨影响MSCT激光定位导引下经皮肺穿刺活检术并发症发生的因素。方法:搜集在MSCT激光定位导引下行肺部穿刺活检的197例病例,统计并发症发生率,并分析相关原因。结果:197例肺穿刺术后并发气胸19例(9.6%),其中肺压缩10%以下气胸15例(7.6%),肺压缩15%～35%气胸3例(1.5%),肺压缩60%以上气胸1例(0.5%);并发肺出血18例(9.1%)。并发症的发生率与病灶大小、进针深度、合并慢阻肺、穿刺次数及穿刺针胸膜夹角大小有关。结论:影响并发症发生率的因素较多,相互之间具有一定的关联,难以确定独立的影响因素,病灶越小、距胸膜越远且合并慢阻肺的患者并发症发生率较高。

Objective：To analyze the incidence of the complications after MSCT laser guided percutaneous lung biopsy （PLB）. Methods： A group of 197 cases undergoing MSCT laser guided PLB in our hospital were randomly selected,and the incidence of the complications was analyzed. Results：Of all patients, 19 cases （9.6% ） developed pneumothorax after PLB, and among these 19 cases,the compressive lung volume less than 10% in 15 cases （7.6%） ,15%～35% in 3 cases （1.5%） and more than 60% in 1 case （0.5%）. 18cases （9.1%） deeloped pneumorrhagia. The occurrence of the complications was closely related to the size of the lesion, the length of the puncture, whether or not the patients had concomitant chronic ob structive pulmonary disease （COPD）, the puncture times and the puncture angle. Conclusion： Not a single factor causes the PLB complications. Several factors are correlated with the incidence of the complications. It is concluded that the small,deep lesions and the pateints who have concomitant COPD are the factors that more likely cause the PLB complications.
