title: [Doppler diagnosis in the localization of incompetent perforating veins].
abstract: If persistent or recurring varicosis is to be avoided, it is vital to locate the incontinent perforating veins in patients with venous insufficiency of the lower extremities. This is the case wherever surgery, sclerotherapy or the use of elastic support is required and especially in the absence of the normal signs of diseased deep veins, such as stasis, dermatitis or ulcerations. The inadequacy of clinical examination or certain instrumental techniques in evidencing the largest possible number of incontinent perforating veins is demonstrated. Personal experience of Doppler testing at a Phlebology Clinic is then presented and it is pointed out that the accuracy of this technique depends essentially on the examiner's experience. Correctly performed the technique gives over 90% accuracy in the preoperative diagnosis of incontinent perforating veins.
