[Renal artery surgery. Choice of surgical technic. Experience apropos of 84 cases].

The choice of the surgical technique in renal artery surgery poses several problems: 1) A retroperitoneal approach may be indicated except when aortic surgery is associated; 2) The usual techniques involve hypogastric venous or arterial autografts. Extra corporeal surgery is reserved for distal lesions or when there are technical difficulties. Complex bypass surgery is reserved for certain Takayashu type diseases. The concept of nephron protection must be emphasised given the risk of obliteration of severe stenosis, despite advances in medical anti hypertensive therapy.
