[Vessel structure and blood supply of free skin transplants in animal experiments in relation to their vessel supply].
In the total abdominal island skin flap of the rat based on both epigastric vessels in the groin, postoperative development after arterial or venous or complete division of the neurovascular bundle was documented. Photographic documentation, planimetry of the surviving skin area were used as methods together with evaluation of the blood supply of the flaps by Xe-133 clearance. The resulting new architecture of vessels was shown photomacroscopically by Indian ink injection. The function of arterial inflow and venous outflow was shown by microangiographical fluorescent methods. Hence, it was possible to combine special operation methods with definite new vessel structures, typical necrotic areas and postoperative mean value clearance results. Due to the difference of the xenon clearance results in individual cases, this method proved incapable of giving a safe prognosis on the survival of the special flap. Fluorescent microangiography pointed to the type of surgery which had been selected, and allowed functional evaluation of the blood supply of the flap.
