Pheochromocytoma and renal artery stenosis.

We present a new case of pheochromocytoma and renal artery stenosis making remark about the haemodynamic role of the last and the effects tha presence of the tumor may have on blood flow changes through the stenosis. Finally, the suggestion is made that in these cases where two causal factors are found, both surgical treatments should be carried out in the same operating time.
