perforator vein

Usually though, it connects with a perforator vein at its middle 1/3.

In this case they are called perforator veins and have a very important role in the venous system hemodynamics.

Perforator veins play a very special role in the venous system, carrying blood from superficial to deep veins.

Normal blood flow is anterograde (going to the heart), and from superficial to deep veins via perforator veins.

The detection of competent perforator veins may be as important as the detection of incompetent ones.

Surgical treatments include the old Linton procedures and the newer subfascial endoscopic perforator vein surgery.

A common indicator for the prescription of such stockings is chronic peripheral venous insufficiency, caused by incompetent perforator veins.

If a perforator valve is insufficient then a reflux flow from the deep to the superficial through the perforator vein will be registered.

Perforator veins are special veins which cross the deep fascia draining the superficial venous system into the deep one.

All collateral veins are better detected this way, including perforator veins, but of most importance is the detection of venous thrombosis.

Toe flexion, active foot dorsi-flexion, and hyper-extension on tip toes, can all be very useful to detect perforator vein insufficiency.

Radiofrequency ablation is used to treat the great saphenous vein, the small saphenous vein, and the perforator veins.

Communicating veins (or perforator veins) are veins that directly connect superficial veins to deep veins.

Along the length of the GSV, it receives numerous collaterals and drains into the deep veins via the perforator veins.

Currently, the VNUS ClosureRFS stylet is the only device specifically cleared by FDA for endovenous ablation of perforator veins.

All veins which are between the skin and the superficial fascia are tributaries and all veins which cross the deep fascia to join the deep venous system are perforator veins.

Nevertheless they can progress to the deep veins through the perforator veins or, they can be responsible for a lung embolism mainly if the head of the clot is poorly attached to the vein wall and is situated near the sapheno-femoral junction.

This type of phlebitis of the great saphenous vein usually is not life threatening in isolation; however, if the blood clot is located near the sapheno-femoral junction or near a perforator vein a clot fragment can migrate to the deep venous system and to the pulmonary circulation.
