[An experimental study on absorbable and non-absorbable suture materials in aortic anastomoses: influence of the growth to suture lines and anastomotic sites].
Ent-to-end anastomoses of the abdominal aorta in dogs and growing pigs were performed with absorbable sutures and non-absorbable sutures. Comparison studies between the two suture materials were done with respect to mechanical properties, angiographic findings, and macroscopic and microscopic examinations. In macroscopic examinations, animals with non-absorbable suture materials developed thickening at the site of the anastomosis and showed protrusion of the suture materials into the intraluminal space of the aorta with growing pigs. However, those findings were not observed in the animals with absorbable suture materials. In histological examinations, prolonged inflammatory reaction around the anastomotic site was observed in the non-absorbable suture group, but excellent healing without any inflammatory reaction was a constant finding in the absorbable suture group. Animals with the absorbable suture materials showed good mechanical properties evaluating the compliance and tensile strength, compared to that of animals with the non-absorbable suture materials. Growth of a aortic anastomosis after application of absorbable suture material seems to be possible without any complication and can be recommended as adequate suture materials for application in young growing humans.
