Below-knee vessels resemble the forearm vascular anatomy and, therefore, methods to improve the outcomes of fistula creation at this level would also help to improve the quality of life for those patients. The aim of the present study was to examine the efforts to improve the functionality of below-knee fistulas in a sample of dialysis patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We retrospectively evaluated the results of ankle fistulas created following preliminary balloon dilatation of both the saphenous fascia and the saphenous vein in 11 patients who were considered eligible if they did not have concomitant venous or arterial lower extremity disease. We assessed the changes in fistula flow within 6\u2009months as well as patency and maturation rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Though the patency rate at 6\u2009months was 63.6% (seven patients), only three fistulas (27.3%) were used for routine dialysis. All mature fistulas were observed in patients with a preoperative posterior tibial artery flow of more than 35\u2009mL\/min.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Saphenous vein dilation throughout the below-knee promotes fistula patency, but the posterior tibial artery shows inadequate response as an inflow supplier at the ankle level.
