Introduction: Abdominal aortic prostheses are crucial in surgical interventions where infected prostheses must be replaced. Though synthetic materials are commonly used, this study explores the use of bovine pericardium for its superior biocompatibility and reduced inflammatory response.

Aim: The objective of this research is to develop a standardized pattern construction for abdominal aortic prostheses to enhance fitting accuracy and reduce manufacturing time, specifically targeting the challenges faced by surgeons in the manual cutting and suturing process.

Methods: This study proposes an optimized cutting template using a sterilizable metal stencil to standardize and expedite the production process. New pattern constructions were created and their manufacturing processes formulated using CAD software for precision.

Results: Three pattern constructions were tested. The first two demonstrated improvements, reducing suturing time and simplifying handling during surgery. Clinical tests in a limited sample of patients confirmed the feasibility of the new designs, with no postoperative complications observed.

Conclusions: The use of a standardized cutting template for bovine pericardium prostheses offers improved clinical outcomes through reduced surgery time and enhanced prosthesis fitting. Further large-scale clinical trials are recommended to validate these findings.
