The measurement of the pulse wave velocity (PWV) is widely used in clinical practice to assess the elasticity of the arterial system. It can be influenced by a number of factors. The present study was undertaken to assess the possible role of anthropometric factors, hemorheological parameters and blood pressure on this element. ⋯ The PWV-diastolic pressure relationship is well-known. In contrast, the effect of the hematocrit and body surface area has never been reported.(ABSTRACT TRUNCATED AT 250 WORDS)

Out of 1,048 Raynaud patients followed for 10 years, only 7.48% underwent surgery. This fact also results from the recent utilization of high-level epidural spinal stimulation, which we perform first, before surgery, in all "critical" Raynaud patients. We treated 40 Raynaud patients with SCS and the results were always positive: excellent in 18, good in 6 and moderate in 6. ⋯ Regular monitoring was carried out both clinically and with noninvasive and hemorheological tests. SCS appears to act like cervicothoracic surgical sympathectomy, but in contrast to the latter, it does not inhibit perspiration. Its mechanism in therefore different but the data is as yet insufficient to allow for more than personal hypotheses.
