What angle are the ends of a graft trimmed during an aortofemoral bypass?

In an aortofemoral bypass procedure, the ends of the graft are typically trimmed at a 45-degree angle. This specific angle is chosen because it facilitates a smooth and effective anastomosis, which is the surgical connection between the graft and the blood vessels. Trimming the graft at a 45-degree angle allows for better alignment and overlapping of the tissue, which enhances the healing process and minimizes turbulence in blood flow.

By contrast, using other angles such as 30 degrees, 60 degrees, or 90 degrees may not provide the optimal exposure and contact surface for the sutures, potentially compromising the integrity of the anastomosis or leading to complications such as leakage or graft failure. Therefore, the 45-degree angle is a standard practice aimed at ensuring the best surgical outcome.
