There was a significant correlation between the inability of the calf pump to reduce foot vein pressure during exercise and the number of capillaries in the skin. It is suggested that the increased number of capillaries secondary to venous hypertension during exercise may be the prime cause of the nutritional abnormalities that eventually cause a venous ulcer.<\/jats:p>","DOI":"10.1002\/bjs.1800680502","type":"journal-article","created":{"date-parts":[[2007,3,2]],"date-time":"2007-03-02T21:00:43Z","timestamp":1172869243000},"page":"297-300","source":"Crossref","is-referenced-by-count":100,"title":["The relationship between the number of capillaries in the skin of the venous ulcer-bearing area of the lower leg and the fall in foot vein pressure during exercise"],"prefix":"10.1093","volume":"68","author":[{"given":"K G","family":"Burnand","sequence":"first","affiliation":[{"name":"Departments of Surgery, Dermatology and Radiology, St Thomas's Hospital , London SE1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I","family":"Whimster","sequence":"additional","affiliation":[{"name":"Departments of Surgery, Dermatology and Radiology, St Thomas's Hospital , London SE1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G","family":"Clemenson","sequence":"additional","affiliation":[{"name":"Departments of Surgery, Dermatology and Radiology, St Thomas's Hospital , London SE1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M Lea","family":"Thomas","sequence":"additional","affiliation":[{"name":"Departments of Surgery, Dermatology and Radiology, St Thomas's Hospital , London SE1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N L","family":"Browse","sequence":"additional","affiliation":[{"name":"Departments of Surgery, Dermatology and Radiology, St Thomas's Hospital , London SE1"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[1981,5,1]]},"reference":[{"key":"2024092713463061400_bib1","volume-title":"The Analysis of the Venous System","author":"Ludbrook","year":"1972"},{"key":"2024092713463061400_bib2","first-page":"300","article-title":"The aetiology and treatment of varicose ulcer of the leg","volume":"24","author":"Homans","year":"1917","journal-title":"Surg.
