Fibrin sealants in supporting surgical techniques: strength in factor XIII

Area of Science:

• Biochemistry
• Hematology
• Surgical Innovation

Background:

• Factor XIII is crucial for natural coagulation and clot stabilization.
• It is frequently incorporated into fibrin sealants for surgical hemostasis, adhesion, and wound healing.
• Factor XIII acts as the terminal enzyme in the coagulation cascade, balancing coagulation and fibrinolysis.

Purpose of the Study:

• To review preclinical data on the role of Factor XIII in fibrin sealants.
• To evaluate the potential benefits of Factor XIII-stabilized fibrin sealants in surgical settings.

Main Methods:

• Review of preclinical studies investigating Factor XIII's function in fibrin matrices.
• Analysis of data concerning clot strength, proteolytic resistance, and hemostatic efficacy.

Main Results:

• Factor XIII cross-links fibrin, increasing clot strength up to 5-fold.
• Factor XIII-stabilized clots exhibit enhanced resistance to proteolysis due to alpha(2)-antiplasmin ligation.
• Preclinical studies show reduced suture-hole bleeding in vascular grafting with Factor XIII-containing sealants.

Conclusions:

• Factor XIII significantly strengthens fibrin clots and improves their resistance to breakdown.
• The inclusion of Factor XIII in fibrin sealants may enhance surgical hemostasis, tissue adhesion, and wound healing.
• Preclinical evidence supports the optimization of fibrin sealant performance with Factor XIII stabilization.
