[Venous end-to-end anastomosis with non-absorbable and absorbable screw flange rings]. / Venöse End-zu-End Anastomosen mit nicht auflösbaren und auflösbaren Schraubflanschringen.

ABSTRACT

Forty veno-venous anastomoses performed on femoral blood vessels of dogs showed good results using a new flange ring system. In 15 cases Palacos rings were used for the anastomoses. Follow-up studies during a period of 8 days to 1 1/2 years showed only one occlusion. Twenty-five anastomoses were performed with absorbable rings of vicryl. Follow-up studies of these anastomoses during a period of 10 days to 26 weeks showed two stenoses and two occlusions. Dissolution of the Vicryl rings lasts up to 26 weeks.
