Abstract
Purpose: The purpose of this article was to investigate clinical ultrasonographic findings and the outcomes of post-pregnancy patients with acquired uterine vascular abnormalities including arteriovenous malformations (AVMs). Materials and Methods: We performed a computerized database search for all patients with ultrasonographic findings of a vascular abnormality including AVM in our referral center between 2000 2008. An ultrasound finding of vascular abnormality was defined as an area of strong hypervascularity within the myometrium and the presence of marked turbulence. The inclusion criteria for angiography were abnormal vaginal bleeding in a hemodynamically stable patient, bhCG serum levels 30 mIU/ml, and ultrasound demonstration of large ( 15 mm on the larger side of the vessel) or multiple vascular lesions. Results: 16 women were identified, of whom 10 (63 %) underwent uterine artery embolization. Angiography confirmed the pre-interventional ultrasound diagnosis of AVM in all cases. AVM feeding arteries were on the left side of the uterus in 80 % of the cases. Residual tissue was ultrasonographically detected in five patients: 2 underwent hysteroscopy and guided curettage following embolization and three received methotrexate. All tissue samples were benign. One small vascular abnormality resolved spontaneously. Conclusion: An acquired uterine vascular abnormality including AVM should be considered in the work-up of post-pregnancy vaginal bleeding.
