Ultrasound diagnostic value and clinical analysis of 61 uterine intravenous leiomyomatosis cases

The diagnostic accuracy of ultrasound was high for IVL located adjacent to the uterus and in FIGO 8 category, especially when it presented with cord-like or beaded morphology and involved the iliac vessels or IVC. Involvement of the iliac veins or IVC and myomectomy were independent risk factors for IVL recurrence. The risk of recurrence for IVL involving the iliac veins or IVC was 6 times higher than that confined to the uterus or para-uterine veins, and the risk of recurrence was 77 times higher for myomectomy than for hysterectomy with bilateral oophorectomy.
