📌 Most AVMs develop secondary to uterine tissue injury (eg, from prior dilation and curettage) rather than as congenital malformations.
📌The standard for AVM diagnosis is angiographic identification of an early draining vein, although color-power Doppler US is increasingly being relied on as a surrogate
📌Both AVMs and RPOC are persistent postpartum findings; however, RPOC can be distinguished from AVMs on the basis of the vascular endometrial component seen in RPOC, whereas uterine AVMs primarily involve ONLY the MYOMETRIUM .
📌Proper identification of AVMs is important because of the potential risk of life-threatening hemorrhage, whether spontaneous or as a result of dilation and curettage.
📌Treatment options for uterine AVMs depend on the clinical situation and include uterine artery embolization and expectant management with close monitoring.
