Design outcomes

Primary

Measure	Time frame
Primary:Operative failure rate, 1-year patency rate, venous occlusion. Secondary: infection, cannulation, ischemia of blood vessels, aneurysm, seroma leakage. Timepoint: Patients will be evaluated at four time points (before and immediately after surgery, six weeks and three months after surgery). Method of measurement: In this study, permutation blocks method was used to generate the sequence of random assignment of people to the studied groups. The sequence of random allocation of people was done using Random Allocation Software and the block size was four. The permutation block method is one of the random allocation methods in which each block is selected according to the number of studied groups. In this study, six blocks AABB (1), ABAB (2), ABBA (3), BBAA (4) ), BABA (5) and BAAB (6). One of the blocks is randomly selected. If the first block, AABB, is selected, the first and second people are assigned to group A, and the third and fourth people are assigned to group B, and this process continues until all the samples are assigned. The characteristic of this method is that the two study groups will have equal numbers.	—
