Honeycomb myometrial vessels — PSV stratification and bleeding?

💡 Uterine AVM/EMV = honeycomb tortuous myometrial vessels + arteriovenous shunting, usually acquired (after D&C/instrumentation/miscarriage/cesarean/CSP). US: grayscale irregular anechoic tubular myometrial channels; color Doppler lights up with high-velocity turbulence, spectral multidirectional high-velocity low-resistance; higher PSV means greater bleeding risk. Key contraindication: no blind curettage/biopsy → massive bleeding.
