In our initial experience with radial artery testing, about 6% of the patients we see have abnormal resting digital studies (we do PVRs). Upon radial artery compression, 17% were found to have inadequate digital PVRs (this was 41 out of 238 limbs). Approximately 12% of our patients were found to have abnormal ultrasound results (small vessel size, calcification, occlusion).
These data continue to hold true today. We have been doing these studies since about 1996.

I would like to pose a question about radial studies for research and comparison.
Can anyone please tell me what % of radial studies come up positive in your labs?
Also when doing the Allen's test what if anything can be used, other then PPG?
Thank you for you input.
