Figure 2. Patient XN16 who is the only case to have died with the mesh in place. This occurred 4.5 years after operation. The upper two panels are aorta from the arch beyond the mesh at low power (a) and high power (b) where the loss of the structure of the media characteristic of Marfan syndrome can be seen. Below (c) the mesh (filaments cut in cross-section, marked) is surrounded by healthy collagen fully incorporating it. At high power (d) the media has a normal appearance. The pathological interpretation is that the support has allowed the collagen to be restored to a normal appearance.
