Task: Answer Verification
Input (English): Question: Is native arterio-venous fistula the vascular access of choice for hemodialysis in end stage renal disease?
Answer: We concluded that Arterialised arm superficial veins after primary AV fistula was the optimal and rational vascular access for hemodialysis providing adequate blood flow during this process. Besides, failure of primary AV fistula should be replaced by secondary AV fistula preferably based on brachial artery.
Output (English): yes
