What really happens - 1

To explain what really happens it is necessary to understand the structure of the vein wall.

The vein wall is made up of living cells held together by a protein called collagen.

There are three layers - the adventitia, the media and the intima.

The adventitia supplies nutrients to the vein wall. The media is the "muscle layer" of the vein wall and causes it to shrink or enlarge. The intima is the inner layer and is in contact with the blood.
When viewed end on, these structures can be seen to follow right around the vein wall.

Remembering that all three layers are made from living cells held together by collagen, we can start to understand the effects of sclerotherapy.

To destroy the vein completely, it will be necessary for the sclerosing agent to kill and cause inflammation across the whole of the vein wall, killing all of the cells of the vein wall.
