Abstract

<p>This study investigated the current status of venous ulcers in Japan. Members of the Japanese Society of Phlebology were asked to complete case-report forms for patients treated for venous ulcer during the previous year. Two hundred and fifty-four limbs with venous ulcer in 224 patients were assessed. Symptomatically, about 20% of limbs had skin changes and a healed ulcer, and 80% had skin changes and an active ulcer. Etiologically, 77% of limbs had primary disease, 18% had secondary disease, and 5% had congenital disease. Anatomically, 74% of limbs had superficial vein insufficiency, 17% had deep vein insufficiency, and 40% had perforating vein insufficiency. Pathophysiologically, 84% of limbs had reflux only, 7% had obstruction only, and 3% had a combination of reflux and obstruction. The venous ulcers were most frequently located at the medial or lateral part of lower limbs. Morphological assessment was performed using duplex scanning in 80% of limbs and venography in 40% of limbs. APG was applied in 36% of limbs for functional assessment. About 80% of patients wore an elastic stocking either constantly or intermittently. Various ointments and wrapping materials were used as treatments for venous ulcer. Seventy-two percent of limbs underwent stripping or high ligation of the superficial veins, and 20% of limbs with insufficient perforating veins underwent subfascial endoscopic perforator surgery or Linton’s procedure. This survey has provided information on the current status of the clinical manifestations and etiology of, and diagnostic methods and treatments for venous ulcer in Japan.</p>
