The purpose of these studies is confirming the effects of the venous flow on the skin flaps in which circulation was designed without arterial inflow. In other words, possibilities of the skin flap lengthening by means of venous circulation and their clinical applications were studied in animal experiments.
The results obtained from animal experiments suspect that lengthening of the skin flap by venous flow is highly possible. Experimental group with saphenous vein flaps have full length of the flap survival in compare to the control group with flaps necrosis in 2/3 of the whole length. Flap tissue edema and severe congestion were inevitable, because in abscence of arterial inflow, venous blood produces the main force on fluid movements between tissue and capillary.
In summary, following clinical characteristics were suspected in venous skin flaps. 1. Contents in venous blood are sufficient to flap survival. 2. Blood movement and resulting metabolism in tissue are forcely affected by surrounding physical and environmental conditions. 3. It is inevitable that the flaps with venous flow have some amount of edema and tissue congestion. 4. The relationship between vein diameter and the flap size is very important in flap congestion. 5. Tissue texture and physical properties play a certain role in flap survival and congestion.
