CT引导下经皮肺穿刺活检并发症的分析

目的探讨CT引导下经皮肺穿刺活检并发症的原因及其预防和处理。方法对300例诊断不明的肺部结节病变行CT引导下经皮肺穿刺活检术,分析主要并发症的发生因素,以及并发症的预防和处理措施。结果300例均穿刺成功,并发症主要为气胸39例(13%),肺出血63例(21%)。气胸与病灶大小,部位及有无肺气肿有关,出血与病灶大小及部位有关。少量气胸或少量出血无需处理,大量气胸需置管引流。结论对于CT引导下经皮肺穿刺活检术的并发症,应以预防为主,而预防的关键在于术前准确的定位,以及术中熟练的操作。

Analysis on Complications Associated with CT-guided Percutaneous Transthoracic Needle Biopsy

Objective To investigate the prevention and treatment of the complications due to CT-guided percutaneous transthoracic biopsy.Methods CT-guided percutaneous transthoracic needle biopsy was performed in 300 patients.The complications and the contributing factors were analyzed.The methods for the prevention and treatment of the complications were suggested.Results CT-guided percutaneous transthoracic needle biopsy was succeeded in 300 cases.The major complications associated with CT-guided needle biopsy included pneumothorax(13%)and pulmonary hemorrhage(%).Pneumothorax was associated with the lesion size,lesion location,and emphysema.Pulmonary hemorrhage was associated with the lesion size,lesion location.A small quantity of pneumothorax or pulmonary hemorrhage were not particularly treated.Conclusion The prevention of complications is important for CT-guided needle biopsy.The key factors to prevent the complications include accurate location of the lesions and skillful intra-operative puncture.
