VNUS Closure |
|||||||||||||
|
VNUS closure is a new technique which avoids
stripping and a groin wound. A catheter is passed up the vein from the
calf. It is carefully placed at the junction between the thigh vein and
the deeper veins. An ultrasound scan is used to place the catheter
precisely.
The catheter is opened to contact the vein wall and an electrical current is passed through the vein wall over a short distance (2mm). This causes the proteins in the vein wall to change shape and contract down. The catheter is slowly pulled down through the thigh vein to the level of the knee. This leaves the vein contracted down and no blood flows through it. It is effectively removed from the circulation achieving the same outcome that stripping of the vein does in traditional surgery. After this the varicose veins in the leg are removed using the same technique as in normal surgery.
