Experimental Study on the Neovascularization of the Vascular Island Flap
|

Abstract
|
|
|
It is common accepted that the initial survival of an vascular island or free flap is due to adequate blood flow in its vascular pedicle. During the healing period the flap can become indepedent of this pedicle as neovascularization from the surrounding tissue proceeds.
The failure to achieve complete vascular patency and total flap survival can prompt an indept retrospective study to correlated the percentage of flap surviving with the type and the time of the vascular interruption. Recognizing, of course, that there can be considerable species variation in any experimental study of flap survival, nevertheless certain similarities to the clinical situation are present.
The following study is undertaken to clarify the survival capacity of the vascular island groin flap in the Wistar rats after interruption of its artery, vein or both vessels on 1, 2, 3, 4 and 5 day of vessel ligation respectively.
We can introduce the conclusions that are followings;
1) All of our flaps survived when either the artery or the vein was ligated on the third day.
2) When both the artery and the vein were ligated, the flap survival occurred from the 5th day of vessels ligation.
3) When either the artery or the vein was interrupted, a greater percentage of the flap survived than when both the artery and vein were ligated.
4) The day of the vessel ligation had greater influence on the amount of the flap survival than did the type of vessel ligated.
