EDITOR-The clinical review of Venous and arterial leg ulcers by Grey
et al is comprenhesive and clear, although some aspects deserve
comment(1). We are agree that venous hypertension is the underlying cause
of venous ulceration. Compression therapy is associated with a protracted
course of healing and multiple recurrences. Skin closure occurs rapidly
when venous hypertension is improved. The ablation of superficial and
perforator vein incompetence provides clinical and hemodynamic improvement
in patients with chronic venous ulcers(2). Subfascial endoscopic
perforator surgery has become the surgical technique of choice for
perforator ablation, although this approach cannot be adopted in all
cases. Small interconnected collaterals between the perforators and the
skin frequently convey the venous hypertension to the skin area, and
surgical procedures are inherently unable to close these vessels.
Surgical intervention has been successful but the advent of foam
sclerotherapy has proven to be an attractive alternative to surgery and
has added a new tool for the treatment of venous ulcers. Recently we have
published 116 patients with chronic venous ulcers treated with ultrasound-
guided injection of polidocanol microfoam (UIPM)(3). To reduce venous
hypertension UIPM was used to selectively sclerose sources of
incompetence. At 6-months`s follow-up, treatment with UIPM achieved
complete healing in 83% of patients with median time to healing of 2.7
months. In comparison with the patients treated with allogeneic cultured
human skin equivalent of a previously reported series, we obtained a
highly significant advantage for our overall results (X2 test, P<_.001. p="p"/>Foam sclerotherapy of superficial and perforating valveless veins is a
well-tolerated and effective outpatient procedure. Major advantages of
sclerosant in foam form with respect to classic liquid sclerosants include
selective effect on endothelium, visibility on ultrasound examination,
predictability of outcome, high sucess rate, and low frequency of
recurrence. Foam sclerotherapy may well prove to be the gold standard for
treatment of chonic venous ulcers in the future(4,5).
