title: Absence of "epitheloid cells" in AV-anastomoses (AVA) for electron microscopy.
abstract: AV-anastomoses were studied in rabbit auricles. After perfusion-fixation with glutaraldehyde and post-osmication AV-anastomoses are to be identified only when serial sections are analyzed. "Epitheloid cells" were not seen in the walls of the anastomosing segments.
