A three dimensional image reconstructed from computed tomography before open surgery. The black line and arrow indicate the frozen elephant trunk inserted during the first stage. The white arrow and white line indicate the Zenith TX-2 Dissection Endovascular Graft placed during the second stage. The yellow/red arrows and yellow/red lines indicate the Zenith Dissection Endovascular Stent (TX-D) placed during the second stage. The blue arrow and blue line indicate the abdominal aortic stent graft device placed during the third stage.

However, two years after the three stage operation (Fig. 1), CT showed that the thoracic aorta was over 60 mm in diameter and that the abdominal aortic false lumen had expanded from 16 mm to 27 mm.
A three dimensional reconstructed image based on computed tomography after open surgery. The black line and arrow indicate the area in which the artificial blood vessel was replaced in this operation. The proximal portion was anastomosed to a Zenith TX-2 Dissection Endovascular Graft and the distal side was anastomosed to the level of the distal Zenith Dissection Endovascular Stent.
