A comparison of the chest x-ray taken before the fistula was repaired and the chest x-ray taken after insertion of the catheter revealed migration of the tip. [Fig. 4]. When we compared the lateral view of the most recent chest x-rays and the ones done after placement of the catheter, we found that the tip of the catheter was migrating in a perpendicular angle to the coronal plan [Fig. 4].
