Abstract
The objective of this study is to investigate the endothelial function in complex regional pain syndrome. A total of 21 patients with CRPS and 15 healthy controls were enrolled. The mean age of patients was 22 ± 4.9 years and the mean duration of the disease was 5.9 ± 2.5 months. Flow-mediated vasodilatation (FMD) technique was performed for evaluating the endothelial function. Parameters were the waveforms obtained and the increase in diameter and blood flow of the brachial artery, which were expressed as the percent change from baseline. The differences of the waveforms obtained in the affected limbs in comparison to non-affected limbs and to controls were statistically significant. We observed a trend of greater percent dilating responses in the affected limbs; however, the differences showed no statistical significance. In macrovascular evaluation, the endothelial function seems to be impaired in the earlier stage of the disease.
