[Autotransplantation of cold preserved human parathyroid gland tissue. Indications--technic--results]

Abstract

Autotransplantation of cryopreserved tissue is of increasing clinical value after parathyroid surgery became more common. The results in the literature show a high rate of non functioning grafts after autotransplantation of cryopreserved tissue in comparison to fresh autografted tissue. The reason for that is a partial necrosis of the tissue caused by the freezing and thawing process. To obtain better results after autotransplantation of cryopreserved tissue the rate of necrosis should be estimated. The loss of functioning cells should be compensated by autografting a greater amount of tissue fragments.
