Introduction: The Brescia-Cimino radiocephalic fistula, originally devised as a side-to-side anastomosis, is simple to perform and provides a smooth vein–artery interface but requires greater mobilization for vein–artery approximation than does the end-to-side approach. Distal cephalic vein ligation is performed to prevent venous hypertension. The study aims to assess primary patency at one month following distal side-to-side radiocephalic fistula creation with and without distal cephalic vein ligation, to assess the effect of distal cephalic vein ligation on flow rates at one month, and to document the occurrence of venous hypertension over one year follow up. Method: A total of 100 patients requiring vascular access for hemodialysis were assigned to side-to-side anastomosis with and without distal cephalic vein ligation. Follow up Doppler exam was performed at one month for assessment of patency and flow rates and after one year clinical exam to document venous hypertension and the need for revision surgery. The quantitative and qualitative variables were evaluated using student t test and chi square test, respectively. Results: The patency rates of distal ligation and no ligation groups were 86.4% and 85.4%, respectively. The proximal flow rates of distal ligation and no ligation groups were 1192+/−812 ml/min and 1217+/−796 ml/min, respectively. The difference was not statistically significant (P > 0.05). Only two cases (5%) with no ligation required revision ligation within one year of surgery.Conclusion: Distal cephalic vein ligation does not increase the proximal cephalic flow rates and primary patency rates after one month. However, venous hypertension was associated in 5% of nonligated cases at one year follow up.
