The vein is used quite frequently to by pass blockage. The veins are first recovered and prepared by removing any valves. It is then reversed and joined by suturing to the artery above the obstruction and the lower end is joined below the obstruction so that blood can bypass and flow through this new venous channel past the obstruction .
