Dacron grafts dilate more than Stretch PTFE grafts after abdominal aortic aneurysm repair – long-term results of a prospective randomized trial

Abstract: Dacron-Prothesen haben eine größere Dilatationsneigung als Stretch-PTFE-Prothesen als Ersatz beim abdominellen AortenaneurysmaLangzeitergebnisse einer prospektiv randomisierten Studie Zusammenfassung. Grundlagen: Wir analysieren die Langzeitergebnisse einer prospektiv randomisierten Multizenterstudie, bei der Patienten mit abdominellen Aortenaneurysmen mit gelatin-beschichteten DoppelVelour-Dacronprothesen (GEL-D), kollagen-beschichteten Doppel-Velour-Dacronprothesen (COL-D) oder Stretch-PTFE-Bifurkationsproth… Show more

“…Investigators have tried using synthetic materials such as expanded polytetrafluoroethylene and Dacron (polyethylene terephthalate fiber) to bypass stenotic arteries in peripheral vascular disease 28,29 and to replace an aneurismal segment. 30 It has been shown that replacement of vessels with purely synthetic polymeric conduits often leads to an early failure of such grafts mainly due to the formation of thrombosis; this is particularly true in the smallerdiameter vasculature (i.e., less than 6 mm) and in the regions of low blood flow. [31][32][33] These materials lack growth potential, and the long-term results have revealed several cases of stenosis, aneurismal formation, thromboembolization, calcium deposition, and infection, mainly due to material failure.…”

“…However, the dilation evolution at very long term remains rarely reported (from 6% at 5 years to 30% at 8 years and from 60% at 10 years to 70% at 15 years). 16,17 Mechanical fibre fracture in vivo, fibre alteration during manufacturing or surgical manipulation and repeated or inappropriate sterilization processes have been highlighted as the main causes of prosthetic dilation. 18−20 Although PET is recognized as biologically stable, biodegradation could occur over time due to the degenerative effect of both tissue fluids and enzymes.…”
