The influence of fibrin stabilization and fibrinolysis on the fibrin-adhesive system. A clinical study using radioactively marked fibrinogen as a tracer.
In many fields of surgery the use of highly concentrated human fibrinogen, which forms a fibrin clot when thrombin is added, is gaining increasing importance for tissue adhesion. A number of experimental and clinical reports on fibrin sealing have been published during recent years. The question underlying our present investigations is as follows: What happens to the tissue adhesive after its application to a wound in clinical use, i.e., how much time is required for complete resorption of the seal due to fibrinolytic processes? Skin graftings of the face (required to close defects caused by the excision of basal or spinal cell carcinomas) were performed by glueing rhomboid flaps or full thickness skin grafts to the wounds with the tissue adhesive to which 125I-marked fibrinogen has been added. Activity counts were recorded daily and CPM were plotted versus time to obtain summation curves. The physiological processes of fibrin stabilization and fibrinolysis are extensively discussed as both factors influence the tissue adhesive and thus have to be accounted for in clinical practice.
