Pin (Perforate Invaginate) Stripping of Varicose Veins

Varicose veins may be surgically removed by any one of several methods. The process of PIN stripping of the larger abnormal superficial veins has several advantages over the widely practiced methods of vein stripping. PIN stripping technique involves stripping the vein into itself in a manner similar to turning a stocking inside out. The PIN stripping technique affords the following benefits when compared to conventional vein stripping:

1) A lower incidence of injury to surrounding sensory nerves which provide for sensation on the upper surface of the foot when the greater or long saphenous vein is stripped (the large, frequently visible vein on the inside of the thigh and leg).

2) A lower incidence of injury to surrounding sensory nerves which provide for sensation on the outside surface of the foot when the lesser or short saphenous vein is stripped (the superficial vein on the back of the leg which starts in back of the knee).

3) Smaller more cosmetically appealing incisions and a minimal amount of bruising is possible because the design of the surgical instruments used to perform PIN stripping of varicose veins.
