1 Long-term evaluation of the replacement of the trachea with an autologous aortic graft 
Emmanuel Martinod, MD, Agathe Seguin, MD, Karel Pfeuty, MD, Paul Fornes, MD, Marianne Kambouchner, MD, Jacques F Azorin, MD, Alain F Carpentier, MD, PhD  The Annals of Thoracic Surgery  Volume 75, Issue 5, Pages (May 2003) DOI: /S (03) Copyright © 2003 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Macroscopic view of a 24-month specimen showing the proximal and distal anastomoses (forceps) with new cartilage rings and the posterior membrane (bottom of the specimen).

3 Fig 2 Histologic examination of the same specimen showing a continuous mucociliary epithelium (star) with an underlying dense connective tissue (asterisk) and cartilage neoformation (arrow).

4 Fig 3 Histologic examination of the same specimen showing ciliated cells with apically numerous cilia (arrow) and goblet (mucus-secreting) cells (asterisk). The Annals of Thoracic Surgery  , DOI: ( /S (03) ) Copyright © 2003 The Society of Thoracic Surgeons Terms and Conditions

5 Fig 4 Histologic examinations of the same specimen showing the cartilage tissue structure: extracellular matrix (asterisk) and chondrocytes (arrow). The Annals of Thoracic Surgery  , DOI: ( /S (03) ) Copyright © 2003 The Society of Thoracic Surgeons Terms and Conditions

6 Fig 5 Macroscopic views comparing a normal trachea (A) with a grafted trachea (B) removed en bloc 3 years after grafting (grafted area outlined by the rectangle). The total number of cartilage rings is similar in the two specimens (50 versus 48, respectively).

7 Fig 7 Extraluminal aspect of the grafted trachea showing the absence of retraction of the grafted area (rectangle) and the preserved intercartilaginous distances in the adjacent areas (arrow).

8 Fig 6 Roentgenograms of the same two specimens as in Figure 5 showing the absence of stenosis of the grafted area and the continuity of the tracheal walls. Spots of calcification are visible.

9 Fig 8 Intraluminal aspect of the grafted trachea showing the absence of retraction of the grafted area (rectangle) and the preserved intercartilaginous distances in the adjacent areas (arrow).
