Six weeks after aortic aneurysm repair, computed tomography (CT) showed mediastinal gas where absorbable gelatin sponge (Gelfoam) was used. A leukocyte scan labeled with indium 111, however, was normal and surgical exploration showed no infection. Sterile gas collections may be seen following absorbable gelatin sponge use many weeks after surgery and 111In-labeled leukocyte scanning may be a useful differential test.
主动脉瘤修复术后六周，计算机断层扫描（CT）显示在使用可吸收明胶海绵（明胶海绵）的部位出现纵隔气体。然而，用铟111标记的白细胞扫描结果正常，手术探查也未发现感染。术后数周使用可吸收明胶海绵后可能会出现无菌性气体积聚，铟111标记的白细胞扫描可能是一种有用的鉴别检查。
