What does flush ligation mean?

I heard this word for the first time while I was reading Trendelenburg operation for varicose veins.

If you don't know about the Trendelenburg operation, in very short, during this surgery; all the tributaries of long saphenous vein at the saphenofemoral junction are ligated and divided. Then the long saphenous vein is "flush ligated" with the femoral vein and then the upper 10 cm of the long saphenous vein is excised.

Flush ligation is tying up the great saphenous vein very close to it's union with the femoral vein. This is done to ensure that no tributaries of the great saphenous vein is left out. You see, if you tie it away from it's union with the femoral vein, you might miss out a tiny veins in between.

It is also recommended to prevent formation of thrombus in the blind loop. Again, if you tie it away, a blind loop of the vein will form; which is a potential space for the formation of thrombus.

That's all!
