Intra- and post-operative findings from the second operation. (a) The X-ray showed that the tip of the catheter may have moved within the cyst, causing the catheter tip to penetrate the cyst. (b) The X-ray showed the rounded tip of the catheter fixed with threads. (c) Intraoperative findings showed that the tip of the catheter penetrated the cyst wall (black arrow). (d) There were cyst walls with a septum on the mediastinal side of the cyst and when incised old bleeding was noted. The walls were opened as much as possible. (e) The tip of the catheter was rounded and fixed with threads. The catheter was then placed back into the cyst and the wound was closed.
