Laser-Doppler Examination Shows High Flow in Some Common Telangiectasias of the Lower Limb

DERMATOLOGIC SURGERY, Issue 4 2005
Imre Bihari MD
Background. The accepted pathophysiology of telangiectasias is reflux from superficial or deep veins. There are physical signs and scientific findings that do not fit this theory but support the possibility of arteriovenous (AV) shunt origin. Objective. If there is a higher flow in spider veins than in the surrounding skin, it means that AV shunts participate in the circulation of the telangiectasia. On the other hand, slow flow indicates reflux as the etiologic factor. Method. Telangiectasias and the surrounding skin of 22 legs of 19 patients were examined with laser-Doppler equipment. Results. The probe over the spider vein found a higher flow value (average 28.2 perfusion units [PU]) than in the surrounding skin (15.6 PU) in 13 limbs, but it was significantly higher only in 5 cases. In 9 limbs, the flow was slower. Conclusion. We interpret the higher flow values as a consequence of open AV shunts. This means that AV shunt pathophysiology was present in some of our cases.

Sclerotherapy of Varicose Veins with Polidocanol Based on the Guidelines of the German Society of Phlebology

DERMATOLOGIC SURGERY, Issue 2010
EBERHARD RABE MD
BACKGROUND Sclerotherapy involves the injection of a sclerosing agent for the elimination of intracutaneous, subcutaneous, and transfascial varicose veins. OBJECTIVE To update guidelines for sclerotherapy of varicose veins. METHODS The guidelines for sclerotherapy of varicose veins of the German Society of Phlebology were updated and modified through a review of the available literature. RESULTS Published clinical series and controlled clinical trials provide evidence to support the elimination of intracutaneous and subcutaneous varicose veins using sclerotherapy. Allergic skin reactions occur occasionally as allergic dermatitis, contact urticaria, or erythema. Anaphylaxis is rare. Transient migraine headaches present more frequently in patients treated with foam sclerotherapy than liquid sclerotherapy. CONCLUSION Sclerotherapy is the method of choice for the treatment of small-caliber varicose veins (reticular varicose veins, spider veins). If performed properly, sclerotherapy is an efficient treatment method with a low incidence of complications.
