Renal artery stenosis surgery: aorto-renal by-pass

A variety of operative techniques can be used for renal revascularization. This discussion summarizes my indications, technique and results of direct aorto-renal bypass. I currently use aorto-renal bypass for all distal main renal artery and branch renal artery reconstructions in the treatment of both atherosclerotic and fibromuscular dysplastic lesions. Early technical success occurs in over 97% of cases. Sustained late success without graft stenosis or degeneration for up to 23 years has been documented in over 88% of cases. In my experience, aorto-renal bypass remains the preferred method for renal revascularization in over one-half of all patients.
