이식된 자가근막의 조직학적 변화에 관한 연구 = THE EXPERIMENTAL STUDY ON THE HISTOLOGIC CHANGE OF THE AUTOGENOUS FASCIA GRAFT

다국어 초록 (Multilingual Abstract)

The autogenous fascia graft has long been used in various surgical procedures on the assumption that fascia autografts remain intact histologically and functionary,
As yet the fate of fascia graft after transplantation has not been elucidated, and especially the morphohistological changes according to the site of transplantation and the degree of tension upon the fascia graft have not been clearly studied. Hence, an experimental study on the survival of the autogenous fascia grafts in relation to the tension state and transplanted site was performed in 24 rats. The gross findings were evaluated monthly and histological examinations were done using light and polarized microscope for two months.
The results are as follows:
1) Orthotopic fascia autografts under the dynamic tension maintained their normal histomorphological structure till 2 months postoperatively.
2) Orthotopic fascia autografts under the static tension showed decrease in their size to the lesser degree than those without static tension. Those under the static tension appeared to maintain their normal histological structure relatively well, but the collagen bundles were compact and slightly irregular.
3) Orthotopic fascia autografts without static tension showed more rapid decrease in their size than those with static tension, and there was wavy appearance of collagen or whorling pattern of dense collagen tissue, so to speak, characteristic structure of normal fascia had almost disappeared.
4) Heterotopic fascia autografts without static tension also showed rapid decrease in their size and more rapid loss of their normal structure than orthotopic fascia autogafts without static tension, along with increase of fibroblasts and capillary ingrowth.
The fascia autografts under the tension remain 'living', and dynamic tension is more contributable than static one to do maintenance of their original size, but tension-free fascia autografts whether orthotopic or heterotopic, lose their original size and normal structure rapidly.
