Twenty-six cases of renal artery stenosis were evaluated with Doppler ultrasound using the pulsatile flow index (PFI). To establish normal values, the PFI in 60 renal arteries in 30 healthy volunteers was obtained. Normal values by PFI ranged between 0.48 and 0.71 (mean +/- SD: 0.6 +/- 0.06). In renal artery stenosis the PFI range was 0.72-0.79. The normal upper limit was 0.71. The PFI failed in three patients; however, an ultrasound examination showed secondary renal disease (two patients with stenosis on both sides with a shrunken kidney on one side, and one patient with hypernephroma on the opposite side). The PFI was normal (14 of 14 patients) in patients without angiographic evidence of stenosis or after successful dilatation.

A case of sarcoidosis is reported, which began 25 years ago. As a late complication the patient developed compression syndrome of the superior caval vein, which was caused by swelling of the lymph nodes. After surgical treatment, which was carried out by removing the regional lymph nodes and implantation of a dacron prosthesis, stenosis occurred within the proximal part of the prosthesis, which was treated by the PTA technique according to the Dotter method.
