Assessment of the radial and ulnar arteries hemodynamic changes by ultrasound in patients with primary palmar hyperhidrosis after thoracic sympathetic block

To evaluate the value of radial and ulnar arteries hemodynamic changes by ultrasound in patients with primary palmar hyperhidrosis after thoracic sympathetic block. This was a prospective study, from January 2016 to September 2016, 23 patients with primary palmar hyperhidrosis were admitted to the First Hospital of Jiaxing City, Zhejiang Province, 92 arteries of these patients who underwent thoracic sympathetic block were enrolled into this study. Diameters, peak systolic velocity (PSV), end diastolic velocity (EDV) and resistive index (RI) of the radial and ulnar arteries were examined one day before and after the operation by color Doppler ultrasound. Spectral waveforms of these arteries were observed, and palms temperature (T), oxygen saturation (SpO(2)), perfusion index (PI) were also measured. Diameters, PSV, EDV, RI, T, SpO(2) and PI of the patients with PH were compared before and after the surgery. The effect of operation was also evaluated. Before surgery, diameters and EDV of the radial and ulnar ar
