[Color-coded duplex sonography in diagnosis of primary varicose veins and recurrent varicose veins].
Varicose vein surgery, adapted to obtaining condition, requires highly accurate preoperative diagnostics as a basic requirement. The Colour Doppler ultrasound allows one to ascertain the morphological, topographical and functional condition of the venous system and thereby makes possible an operation appropriate for the stage. Thirty-six patients who preoperatively were subject to this examination could be clearly classified according to the localisation of the points of insufficiency; also existing insufficient perforans veins were identified. Eleven patients suffering from relapse varicose veins were examined. In the course of examination we identified crosse and parva relapses as well as perforans insufficiencies and subsequently removed them surgically. Our results definitely show that clinical use of colour Doppler ultrasound in the field of preoperative varicose vein diagnostics has considerable advantages compares with the hitherto existing methods and therefore should be applied more extensively.
