title: The lymphatics in experimental flaps.
abstract: The lymphatics dilate greatly after a  flap delay procedure. After they return to normal in two weeks, they do not undergo further dilatation after a second delay; this suggests that alternate pathways are opened, possibly lymphaticovenous communications, for the egress of lymph. When hexamethonium is given before a primary delay, the delay is not followed by lymphatic dilatation in, or gross edema of,the flap.
