Overview

Es wurde an Arterien- und Venenanastomosen und an fortlaufend genahten Langsarteriotomien gezeigt, daB heilende Anastomosen mit resorbierbarem Nahtmaterial hergestellt werden konnen. Nach 80 Tagen war das Nahtmaterial lichtmikroskopisch nicht mehr nach- weisbar, entsprechend trat auch keine Fremdkorperreaktion mehr auf. Die Durchgangigkeitsrate betrug ohne Verwendung von Heparin an Arterien nach 1 - 234 Tagen 98% und an Venen nach 1 - 60 Tagen 83%. Durch den Vergleich zwischen Turbulenzindex der Anastomose mit dem rasterelektronenmikroskopischen Bild konnten GrundzUge der Anastomosenheilung studiert werden. Die Wechselwirkung zwi- schen Hamodynamik und Morphologie wurde eindeutig belegt. Summary Simple end-to-end anastomoses were performed in the common caro- tid and femoral arteries and in the jugular and femoral veins of dogs. In other dogs, lateral sutures (running) consisting of ab- sorbable material made from polyglycolic acid were inserted. No occlusions, aneurysms, or infections occurred in the arteries. Without heparin, the patency rate after up to 234 days was 98%. In veins, the observation period was 60 days and a patency rate of 83% was found. All vessels were studied by angiography and by light and electron microscopy. Additionally, an original method of hemodynamic assessment was used (Turbulence Index). The al- ternating effect of morphological variations in the vessel wall and the degree of blood flow disturbance was evident. Literatur 1.
