DSA Innova CT重建在体表区域定位经皮肺穿刺活检术的应用价值

The application of body surface localization by virtue of Innova CT reconstruction combined with DSA guidance in performing percutaneous fine needle biopsy of lung lesions

目的探讨DSA结合Innova CT重建在体表区域定位经皮肺穿刺活检术的临床应用价值。方法选取肺占位性病变患者21例,作体表区域定位后行旋转DSA采集,重建Innova CT图像,制订精确穿刺方案,在DSA导向下行经皮肺穿刺活检术。结果经皮肺穿刺活检取材41次,40枚标本取得组织病理结果,阳性率97.6%,其中1例术中发生气胸,发生率4.8%。结论DSA结合Innova CT重建引导体表区域定位经皮肺穿刺活检术定位准确,操作简便,安全性高,在诊断肺占位性病变中具有重要的应用价值。

Objective To evaluate body surface localization by virtue of Innova CT reconstruction combined with DSA guidance in performing percutaneous fine needle biopsy of lung lesions.Methods Twenty-one patients with solid lung lesions were enrolled in this study.Before percutaneous lung needle biopsy,DSA rotation scanning was performed.Based on the reconstructed Innova CT images,precise puncture scheme was formulated.Then,under DSA guidance,percutaneous fine needle biopsy of lung lesions was carried out.Results A total of 41 percutaneous fine needle biopsies was made,of which definite pathologic diagnosis was obtained in 40,with a positive rate of 97.6%.Pneumothorax occurred in one patient（4.8%）.Conclusion Percutaneous lung needle biopsy with the help of body surface localization,which is determined by Innova CT reconstruction images,and DSA guidance is a safe and technically-simple procedure with high accuracy in localization.It is of great value in the diagnosis of pulmonary spaceoccupying lesions.
