Healing of microvascular arterial anastomoses, as seen on corrosion casts by scanning electron microscopy.
We made 44 microsurgical anastomoses in the femoral artery in rats. The healing was studied from one day to 4 months, by making an acrylic cast of the lumen of the femoral artery and the surrounding vessels, and examining the cast by scanning electron microscopy. The method proved to be easy and relatively quick, and it limited the possibility of artifacts. The high depth of focus permitted simultaneous study of the main lumen and of the perivascular structures after microvascular anastomoses.
