Two hundred and ninety-nine were considered to have uncomplicated primary varicose veins, with saphenous incompetence. The remaining 118 presented with past or current skin ulceration, prominent pain and swelling, or both. Ascending and descending venography and further Doppler studies revealed only 18 patients (17 with ulceration) with an incompetent long saphenous system and ankle perforators as the only identifiable abnormalities. In 12 of these, patients' dorsal foot vein pressures were measured at rest and the maximum fall demonstrable after exercise expressed as a percentage of this (12.9 per cent \u00b1 6.0). This test was repeated with a narrow tourniquet inflated to 160 mmHg, applied to the mid-thigh (35.6 per cent \u00b1 7.4) (P &amp;lt; 0.05), and again after accurate groin ligation and stripping of the long saphenous vein to the knee (31.9 per cent \u00b1 10.7) (P &amp;lt; 0.05). These results seem to validate the use of the foot pressure\/tourniquet test in assessing the relevance of saphenofemoral incompetence, and suggest in a proportion of venous ulcers this is a princical factor.<\/jats:p>","DOI":"10.1002\/bjs.1800711006","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T00:09:56Z","timestamp":1172880596000},"page":"754-755","source":"Crossref","is-referenced-by-count":123,"title":["Long
