目的:评价CT引导下经皮穿刺在肺部弥漫性病变中的诊断价值。方法:对采用半自动弹簧活枪行CT引导下经皮穿刺活检的17例肺部弥漫性病变患者资料进行回顾性分析。结果:17例患者均穿刺成功并获得病理结果。3例少量气胸,未经特殊处理自行吸收,1例中量气胸,经抽气治疗后好转;3例肺内出血,1例咯血,经对症处理后吸收。结论:对肺部弥漫性病变行CT引导下经皮肺穿刺活检是一种快速、有效的方法,对指导该类疾病的临床诊断治疗具有重要意义。 Objective: To evaluate the value of CT-guided percutaneous puncture in the diagnosis of diffuse lung lesions. Methods: The data of 17 patients with diffuse pulmonary lesions underwent percutaneous biopsy with semi-automatic spring live gun were retrospectively analyzed. Results: All the 17 patients were successfully punctured and pathological results were obtained. 3 cases of a small amount of pneumothorax, without special treatment of self-absorption, 1 case of pneumothorax, after the improvement of the suction therapy; 3 cases of intrapulmonary hemorrhage, 1 case of hemoptysis, after symptomatic treatment of absorption. Conclusion: CT-guided percutaneous pulmonary biopsy is a fast and effective method for the diagnosis of pulmonary diffuse lesions. It is of great significance to guide the clinical diagnosis and treatment of such diseases.
