What this trial studies

This is an interventional, single-arm procedure study using Doppler ultrasound to locate perforator points for angiopuncture in people with primary dysmenorrhea. Participants receive angiopuncture at Doppler-identified sites and pain and safety measures are recorded before and after the procedure. Eligible participants have at least 6 months of menstrual pain with regular 28–32 day cycles and no pelvic pathology on transvaginal ultrasound; those with coagulopathy, recent analgesic use, or secondary dysmenorrhea are excluded. The trial is led by City University of Hong Kong with clinical conduct at The Third Affiliated Hospital of Changchun University of Chinese Medicine.
