Summary

A new bovine collagenic prosthesis (Solcograft P) was tested in animal experiments. In 45 dogs the infrarenal abdominal aorta was substituted. During a follow-up period of up to 18 months the functional rate amounted to 88 %. Joint-crossing iliaco-femoral bypasses were implanted in 31 dogs, 5 times in both sides. For the new bovine collagenic graft the functional rate ran up to 83 %, during a follow-up period of 9 months. A wound infection was observed twice in the inguinal region thus exacting the removal of the prosthesis. An aneurysm was not observed. In our opinion the satisfying results are due to the compliance of the new prosthesis which is similar to natural artery.

Zusammenfassung

Eine neue bovine Kollagenprothese (SolcograftP) wurde im Tierexperiment erprobt. Bei 45 Hunden wurde die infrarenale Aorta abdominalis ersetzt. In einer Nachbeobachtungszeit bis zu 18 Monaten betrug die Funktionsrate 88%. Gelenküberschreitende iliaco-femorale Bypässe wurden bei 31 Hunden, davon 5mal beidseits, implantiert. Für die neue bovine Kollagenprothese beträgt die Funktionsrate bei einer Nachbeobachtungszeit von bisher 9 Monaten 83%. 2mal kam es zu einer Wundinfektion in der Leiste, die schließlich die Entfernung der Prothese erforderlich machte. Ein Aneurysma wurde nicht beobachtet. Die befriedigenden Ergebnisse sind unserer Meinung nach auf die gute Compliance der neuen Prothese zurückzufüühren, die der natürlichen Arterie weitgehend entspricht.
