“…grafts are dilated slowly after implantation. Sladen et al [11] and Riepe et al [9] reported a ªphysio-logicalº graft dilation with diameters increased by 15±19 % within the first days and 35 % within the first 6 years after implantation. This dilation was referred to expansion of the knit without yarn fracture.…”

“…A dilation of more than 50 % was found to be correlated with aneurysm formation and graft rupture. Sladen et al [11] compiled a total of 18 reported cases of aortic prosthetic graft ruptures until 1986. Muto et al [6] reported an aneurysm arising in the body of an innominate-abdominal aortic bypass graft 4 years after implantation.…”

“…Since then the rates of complications have been reduced significantly after introduction of the reinforced materials [3,4,10]. Presently, the very small but still existent rate of graft failure due to dilation and rupture is associated with many conditions such as fabrication defects, multiple sterilization, false storage, damage during the operation, infection, hematoma, host vs graft reaction, mechanical stress, and material fatigue [1,2,3,6,11]. Among these, infection of prosthesis in contaminated wounds, manufacturing errors and mechanical stress are discussed as the main reasons for deterioration of prosthesis walls.…”

Late aneurysm formation in a femoro-popliteal polytetrafluoroethylene graft

Since improvement in the material, true aneurysms and pseudoaneurysm formations have become relatively rare complications after femoro-popliteal reconstruction with polytetrafluoroethylene (PTFE) grafts. We report a case of late graft rupture and pseudoaneurysm formation within the straight femoral part of a femoro-popliteal bypass with reinforced (PTFE-wrapped) Gore-Tex graft. The rupture occurred 7 years after implantation without history of direct traumatization. Intraoperatively the whole bypass showed macro- and microscopically visible deterioration of the wall with almost complete disruption at the site of the aneurysm. The graft had to be replaced completely. In conclusion, we recommend continuous long-term follow-up of these patients preferably with duplex ultrasonography.

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-Bifurkationsprothesen behandelt wurden. Das Dilatationsverhalten der Prothesen wird mittels Computertomographie evaluiert.Methodik: Zwischen 1991 und 1998 wurden 164 Patienten nach Alter, Geschlecht, Diabetes, Abfluss und Nikotinabusus randomisiert. 55 Patienten erhielten GEL-D, 51 COL-D und 58 Stretch-PTFE-Prothesen. Bei 30 Patienten wurde eine Computertomographie zur Evaluierung des Dilatationsverhaltens der Prothese durchgeführt.Ergebnisse: Die mediane Nachbeobachtungszeit war 77 Monate. Es fanden sich keine statistisch signifikanten Unterschiede zwischen den drei Gruppen hinsichtlich medianem Patientenüberleben und Offenheitsraten der Prothesen. Die primäre Offenheitsraten war 98% in der PTFE, 94% in der COL-D und 92% in der GEL-D Gruppe (p ¼ 0,4). In 30 Patienten wurde mit einer medianen Nachbeobachtungszeit von 61 Monaten eine Computertomographie durchgeführt und hierbei eine signifikant geringere Dilatationsneigung bei PTFE-Prothesen festgestellt. Der mittlere Durchmesser im Bereich des Prothesenkörpers war 110% AE 25% bei PTFE, 132% AE 12% bei GEL-D und 131% AE 9% bei COL-D-Prothesen verglichen mit der auf der Verpackung angegebenen Ausgangsgröße.Schlussfolgerungen: Trotz einer geringeren Dilatationsneigung der Stretch-PTFE-Prothesen sind die 3 unterschiedlichen Materialien gleichwertig hinsichtlich Funktion und Komplikationsraten in der Langzeitbeobachtung.Summary. Background: In this long-term follow-up of a prospective randomized multicentric trial, warp-knitted gelatin-coated double-velour Dacron (GEL-D), warp-knitted collage-coated double-velour Dacron (COL-D) and stretch PTFE bifurcation grafts implanted in patients with abdominal aortic aneurysms (AAA) were compared for their long-term results and their dilatation was evaluated by CT.Method: Between 1991 and 1998, 164 AAA patients were prospectively randomized and stratified for age, gender, diabetes, run-off and nicotine consumption. Of these, 55 received GEL-D grafts, 51 COL-D grafts and 58 stretch PTFE grafts. Thirty of them underwent follow-up CT (Computerized Tomography) and graft dilatation was evaluated.Results: The median follow-up time was 77 months. No significant differences were found between the 3 graft materials in median survival and patency rates. The primary 8-year patency rate was 98% for PTFE, 94% for COL-D and 92% for GEL-D (p ¼ 0.4).
