Uterine Arteriovenous Malformation: A Pictorial Review of Diagnosis and Management.

Uterine arteriovenous malformation (UAVM) is a rare condition and is classified as either congenital or acquired UAVM. Patients with UAVMs usually experience miscarriages or recurrent menorrhagia. Ultrasound is used for the initial estimation of UAVMs. Computed tomography and magnetic resonance imaging are noninvasive and valuable methods that provide good compatibility with digital subtraction angiography to support the diagnosis and treatment of UAVM. Timely diagnosis is crucial to provide appropriate treatment for alleviating complications. This article presents a pictorial and literature review of the current evidence of the diagnosis and management of UAVM.

Intra-abdominal fetus in fetu presenting at 31 weeks gestational age.

Fetus in fetu (FIF) is a rare anomaly of diamniotic monochorionic twins, in which a malformed fetus resides in its twin's body. This report shows a case with the prenatal diagnosis of FIF at Tu Du hospital. A 23-year-old woman, first-time pregnant, presented at the hospital with an abdominal mass in the fetus at 31 weeks and 4 days of gestation. The ultrasound showed an abnormal mass with the images of calcified features located in the left hypochondriac region and the kidney's upper pole. These images had shapes of skull, femur, spine and became more apparent as the fetus grew. Then, the patient was monitored and delivered at our hospital. The infant was moved to the Children's Hospital 1 and diagnosed with FIF by ultrasound. The surgical resection was performed at 12 days of birth.

Acquired life-threatening uterine arteriovenous malformation treated by endovascular embolization.

Uterine arteriovenous malformation (AVM) is a rare condition that may lead to a life-threatening state. The urgency of diagnosis and treatment for uterine AVM should be emphasized. This case report describes a 42-year-old woman with a vaginal hemorrhage. In the previous month, the patient also had a hemorrhage after induced abortion that required a bilateral artery suture hemostasis of the uterus. On ultrasound, there was a lesion suspected by acquired AVM. Magnetic Resonance Angiography and Digital Subtraction Angiography was indicated to confirm the diagnosis. The patient was successfully treated by uterine artery embolization. After 6 months, the re-examined result showed no lesion of AVM.
