1. An improved method of aorto-renal reconstruction in renal artery stenosis is described.
2. The Dacron prosthesis is inserted high in the aorta, thus avoiding a recurrent course and limiting turbulence.
3. The prosthesis is inserted end-to-end in the reconstructed renal artery.
4. On the right side the restructured renal artery is placed anterior to the vena cava.
5. These modifications result in a wide anastomosis with maximum haemodynamic effectiveness.
