Graft hemostasis: an alternative to preclotting

Area of Science:

• Vascular Surgery
• Biomaterials Science
• Medical Device Sterilization

Background:

• Preclotting prosthetic grafts is a standard procedure.
• Existing methods may have limitations in certain patient populations.
• Heparinized patients require specific graft preparation techniques.

Purpose of the Study:

• To introduce and evaluate a new method for preparing prosthetic grafts.
• To assess the simplicity, safety, and effectiveness of the alternative technique.
• To provide a viable option for graft preparation in heparinized patients.

Main Methods:

• Prosthetic grafts or patches are soaked in autologous blood.
• The soaked grafts undergo a three-minute autoclaving process at 131°C (270°F).
• The prepared graft is then inserted into the patient.

Main Results:

• The described method is simple to perform.
• The technique has been demonstrated to be safe.
• The method proved effective for prosthetic graft preparation.

Conclusions:

• This autoclaving technique offers a safe and effective alternative to preclotting.
• The method is suitable for prosthetic grafts and patches in heparinized patients.
• The procedure is straightforward and can be readily implemented.
