Modifications that can be used to obtain an appropriate size-match between the femoral vein (FV) and the aorta. (A) The most common configuration is a straight end-to-end anastomosis between the FV and the aorta. (B) Longitudinal aortoplasty. (C) The pantaloon configuration is used to accommodate a larger range of aortic diameters. (D) A V-shaped venoplasty can be used to increase the circumference of the FV graft.
