Abstract
Thirty patients with 31 saphenous vein loop fistulas (SVLF) constructed in the thigh were followed up for 1–31 months. The predicted patency rates for these blood access devices were 75% at 1 year and 43% at 2 years. For 277 patients with direct arteriovenous (A‐V) fistulas located in the forearm (FF), these percentages were 85% and 83%, respectively. There were several differences between the 2 groups, including a higher percentage (84%) of women in the SVLF group than in the FF group (39%,p < 0.0005). In addition, 19% of SVLF patients had polycystic kidney disease, while only 10% of the FF patients suffered from this disease. The incidence of false aneurysms was significantly higher with SVLF (16%) than with FF (2%,p < 0.0005).
