Abstract
INTRODUCTION AND HYPOTHESIS: To compare blood flow of the dorsal clitoral artery in women diagnosed with provoked vestibulodynia (PVD) and in healthy controls using color Doppler ultrasonography. We hypothesized that women with PVD would have a restricted blood flow compared to controls. METHODS: This cross-sectional study evaluated the function of the dorsal clitoral artery through the spectral wave analysis of color Doppler ultrasonography (US) in 20 women diagnosed with PVD according to Friedrich's criteria and 21 healthy controls. Participants were evaluated during their follicular phase and were asked to abstain from sexual activities 24 ho prior the examination. Assessment was performed by an assessor blinded to participant diagnosis, in the morning after a 10-min rest period in a supine lying position in a room with temperature set at 22 °C. Measurements of the peak systolic velocity (PSV), time-averaged maximum velocity (TAMX), end-diastolic velocity (EDV), pulsatility (PI) and resistance index (RI) were performed at rest considering the mean value of three consecutive waveforms. RESULTS: Women with PVD and healthy controls did not present any statistically different baseline characteristics. Participants with PVD presented higher values of Doppler-US PSV, TAMX, EDV and RI compared to controls (p ≤ 0.05), which are suggestive of a decrease in blood flow. However, non-significant difference was found regarding PI values between the two groups (p > 0.05). CONCLUSION: Our findings revealed decreased peripheral tissue perfusion in women with PVD compared to healthy controls using color Doppler US, based on the alteration of four of the five assessed data of US parameters.
