title: The effect of dextran on the incidence of thrombosis in microvenous Nakayama ring pin anastomoses. Including further studies on the histopathology of Nakayama anastomoses.
abstract: Anastomoses of the posterior facial veins in the rabbits neck (diameter appr. 1.5-2.0 mm) were performed under the operating microscope, using the Nakayama ring pin stapler. Immediately before the operation the animals received clinical dextran (mw 70000) or physiological saline intravenously in a double-blind randomized pattern. The total incidence of partial or complete thrombosis in this experiment was low (around 10%). No difference between the two groups were detected. All anastomoses were examined in vivo, under the microscope and histologically. The histological findings are penetrated.
