traumatic cortical damage, we found at reoperation
cortical adherences with the dural patch.
Pathologic examination showed in all these cases
a vascularization and fibroblastic infiltration of the
dural substitute with good incorporation into the
surrounding host dura. This phenomenon is on the
basis of dura mater regeneration [30] and is promoted
from the connective tissue of the Tutoplast
pericardium that acts as a scaffold for the fibroblasts
proliferation inside the graft itself.
The cost of the Tutoplast pericardium is $220 for
20 cm 2 . This price is similar to that of the allograft
(i.e., Alloderm, $637 for 75 cm 2 ) and synthetic graft
(i.e., expanded polytetrafluorothylene, $1,080 for
144 cm 2 ).
In conclusion, it is questionable if the four complications
of the presented series have to be ascribed
to the dural plasty, but even if we assume
that there is a relationship, our results remain satisfactory.
Therefore, from our experience we can
conclude that dehydrated human pericardium, sterilized
by � irradiation is a valuable alternative when
autologous material is not available for dura mater
repair.
