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.
Who should consider this trial
Good fit: People with primary dysmenorrhea for at least 6 months, numeric pain score ≥2, regular 28–32 day cycles, 4–7 day periods, and no pelvic pathology on transvaginal ultrasound are ideal candidates.
Not a fit: People with secondary dysmenorrhea, coagulopathy (INR >1.5), recent analgesic use within 48 hours, or irregular cycles are unlikely to benefit from or be eligible for this procedure.
Why it matters
Potential benefit: If successful, this approach could offer a non-drug option to reduce menstrual pain and lower reliance on analgesics.
How similar studies have performed: Some acupuncture-related and local vascular-targeting techniques have shown pain relief in dysmenorrhea, but Doppler-guided angiopuncture for this condition is relatively novel with limited prior data.
