Modified crossover and guidewire loop technique for double-balloon angioplasty of the aortic bifurcation

A modified form of crossover railroad technique is described for iliac and aortic bifurcation obstructions in which the iliac occlusion is crossed from the opposite side by a guidewire which is brought out through the ipsilateral puncture site. After forming a loop in the abdominal aorta, dilatation with two balloons is performed. This procedure was successfully performed in 2 patients having iliac artery occlusions and aortic bifurcation obstruction.
