经皮穿刺肺活检诊断肺部病变尤其是肺外周结节/肿块性疾病创伤小、诊断率高，其主要并发症包括气胸和出血，空气栓塞、皮下气肿、肺内感染播散以及穿刺针道恶性肿瘤种植等并发症少见。大多数并发症无需特殊处理，气胸量较大或者症状明显时可以置管引流，出血量较大者可以输血以及对症治疗，空气栓塞较重时行高压氧治疗。活检针直径较大、吸烟、病变胸膜距离远、多次穿刺活检和操作时间长等是发生并发症的危险因素。

Percutaneous lung biopsies ( PLB) yield high diagnostic accuracy for lung lesions , especially pe-ripheral lung nodules or masses , with micro-invasion.The most common complications include pneumothorax and hemorrhage.Air embolism, subcutaneous emphysema , pulmonary infection dissemination following biopsy , malignant seeding of needle tract are seldom .Most complications can resolve without treatment .The chest tube drainage for pneumothorax , blood transfusion for hemorrhage and hyperbaric oxygen therapy for the air embolism are needed when the complications are serious.The big size needle, smoking, long intrapulmonary path, number of needle passes and long puncture time are the risk factors for the complications .
