Stroke rate in redo coronary artery bypass surgery has remained a stumbling block, where the aorta is used as origin for the top end of the vein graft. Avoiding the side-clamp on these redo aortas by using the Vettath’s Anastomotic Obturator (VAO) technique of anatomosing the vein graft could bring this down. We have also been able to use this technique in combined aortic valve replacement and CABG. These two situations where the VAO is used are elucidated here.
