RESUMO
Proximal involvement of the innervation of the arm is a well recognised cause of hand symptoms; a proximal vascular abnormality is rarely responsible. This case report describes such a rare cause, namely, a post-stenotic aneurysm of the subclavian artery due to an abnormal first rib but in the absence of a cervical rib or scalene bands.

Renovascular hypertension caused by renal artery stenosis was a coincidental discovery in 5 of the 6 patients presented. They did not have any comlaint and it was by routine bloodpressure measurement that hypertension was diagnosed. In one patient without hypertension stenosis of both renal arteries was seen on the aortography for an infrarenal aortic occlusion. Depending on the extent and localisation of the stenosis unilateral renal artery stenosis was treated by a saphenous vein graft interposition, or by an aortorenal vein patch. In a man with bilateral renal artery stenosis a venous bridge was constructed. Once an unilateral nephrectomy was necessary, the kidney being atrophic and a vascular correction impossible.
