Bipolar diathermy treatment of long saphenous vein varicosities.

A new technique of endoluminal diathermy of the long saphenous vein using a bipolar electrode is described. This is safer than conventional unipolar diathermy and histological examination of the diathermied veins shows similar appearances using unipolar and bipolar diathermy. Clinical assessment of both techniques yields similar results. Endoluminal bipolar diathermy is simple and relatively painless compared with conventional stripping of the long saphenous vein and can be recommended.
