ABSTRACT
Ulcers of the lower extremities have high prevalence
and incidence. Their chronicity and frequent
recurrences are two of their most important
characteristics. Despite proper etiologic treatment
and the great variety of dressings available, the
healing rate and recovery speed remain low.
Therefore, we conducted a study to obtain skin
substitutes for clinical application by isolating and
cultivating keratinocytes, which were seeded on a
fibroblast-containing fibrin gel at high density. Hence,
a new practical and inexpensive skin equivalent of
straightforward and easy-to-perform transplantation
was developed. Before starting the clinical trials to
evaluate its advantages and applicability, we
conducted a preliminary test to determine if the
changes to the standard technique affected its
feasibility and action. For this purpose, we implanted
the new equivalents into six patients with chronic
ulcers unresponsive to treatment. Outcomes in
these patients showed that skin equivalents were
feasible, effective, easy to handle and had rapid
action on target tissues. All patients who completed
the procedure recovered. An excellent example was
a patient with a chronic lesion refractory to multiple
conventional treatments that had been present for
six months.
