| 摘 要： | 目的 观察膜周部室间隔缺损（VSD）封堵术前后的胸部X线表现，总结封堵器在常规胸片上的影像特点。方法 分析资料完整的Amplatzer VSD双面伞封堵VSD患者33例术前及术后4～7 d内的胸部后前位及左侧位X线胸片。结果 大部分VSD患者封堵术后后前位胸片上封堵器位于第8～9椎体正中线的左侧，在形态上呈现1个点、2个点，偶可见1个点1个圈。侧位上封堵器均位于膈肌-脊柱交汇点与胸骨角连线的左前方，多呈2个点，部分呈“H”形。封堵术后短期内即出现肺部X线表现有不同程度的改善。结论 正确安置的VSD封堵器在胸片上具有一定的显影特征，常规胸片可以用来判断VSD介入治疗的疗效以及封堵器的位置和形态。

| Abstract: | AIM To explore the chest radiographic appearance of perimembranous ventricular septal defect (VSD) before and after transcatheter closure with Amplatzer occluder and to summarize the radiographic characteristics of VSD occluder on chest radiography. METHODS Plain chest films in posterior-anterior view and left lateral view were studied in 33 patients before and 4-7 days after transcatheter closure. RESULTS After the procedure, most VSD occluders were located between T8 and T9, left of anterior midline on the posterior-anterior roentgenogram. The occluders presented one dot or two dots, occasionally one dot and one circle. On lateral chest radiographs, all occluders located the left anterior of the line between the diaphragm and spine crossing and the sternal angle. Most occluders presented two dots and some were like “H” shape. In most patients, the chest radiographic appearance improved to some extent after the procedure. CONCLUSION The ventricular septal defect occluders have a characteristic radiographic appearance when properly positioned. Plain chest radiographs can identify the effects of transcatheter closure as well as the location and shape of the occluders in patients with VSD. |
