Summary
Biosynthetic grafts offer a promising alternative for replacing infected vascular grafts when autologous veins are unavailable. These materials demonstrate good durability and resistance to reinfection, though their mechanical properties and initial thrombogenicity require careful consideration.
Area of Science:
- Vascular Surgery
- Biomaterials Science
Background:
- Autologous veins are ideal for infected vascular graft replacement due to superior handling, durability, and reinfection resistance.
- Alternative materials are necessary when autologous options are unsuitable, each with distinct pros and cons.
Purpose of the Study:
- To evaluate the efficacy of xenogeneic and biosynthetic materials as alternatives for infected vascular graft replacement.
- To assess the durability and reinfection rates associated with these alternative graft materials.
Main Methods:
- Review of clinical series utilizing xenogeneic materials, specifically bovine and equine pericardial patches.
- Application of self-made tube grafts in aortic regions and for iliacofemoral prosthetic graft and shunt infections.
Main Results:
- Clinical series indicate promising results regarding the durability of xenogeneic and biosynthetic grafts.
- These materials show good resistance to reinfection in infected vascular graft settings.
Conclusions:
- Biosynthetic materials are feasible for replacing infected intracavitary and extracavitary vascular grafts.
- Low reinfection rates are achievable with biosynthetic grafts, but their unique mechanical properties and initial thrombogenicity must be managed.
