超声引导下经皮肺活检对外周肺部病变的诊断分析

Analyses of peripheral pulmonary lesions diagnosis on ultrasound;percutaneous lung biopsy

目的探讨B超引导下经皮肺活检对靠近胸壁原发性肺癌、肺转移性癌以及非恶性肺疾病的诊断价值。方法 20例B超检查能确定部位靠近胸壁的肺内病变患者,先进行超声检查,观察病变大小、结构、血管分布,确定最佳穿刺点、穿刺角度以及进针深度。行B超引导下经皮肺活检术,同一患者不同位点取材3~5块,并把取得的肺组织送病理检查。结果 20例一次性成功,20例获取组织确诊,穿刺后无气胸,1例咯血并发症。结论超声引导下的穿刺活检是明确外周肺部病变性质的安全有效检查方法。

Objective To investigate the value of ultrasound in guidance of percutaneous biopsy in peripheral pulmonary lesions（primary lung cancer, lung metastases, no malignant disease）. Methods This study focused on 20 patients with single peripheral pulmonary lesions by ultrasonic sound. to observe size,configuration, vascular demonstrated of lesions, To determine the site,degree and depth of puncture. The core needle（18-gauge） percutaneous biopsy, were performed in all lesions, 3~ 5 pieces of tissues are removed from different site of the patient, are made histologically. Percutaneous lung biopsy are achieved with only one attempt for 20 patients. None of pneumothorax occurs, 1 case occur hemoptysis. Results percutaneous biopsies were performed successfully in the active areas of all lesions. The sampling success rate and pathological diagnosis rate were 100%. Conclusions CEUS percutaneouslung biopsy of ultrasound in guidance provided useful diagnostic information about peripheral pulmonary lesions. it is a promising technique for guaranteeing the accuracy,success, and safety.
