Choriocarcinoma is a highly malignant neoplasm arising from the trophoblast of a human pregnancy, which may have distant spread to multiple organs, particularly to the lung. We report a case of a pulmonary arteriovenous fistula that developed after chemotherapy within a choriocarcinoma metastasis. A 24-year-old female with a history of uterine choriocarcinoma presented with multiple hypervascular pulmonary nodules on the initial chest computed tomography (CT) scan, consistent with lung metastases. Four months after chemotherapy, follow-up chest CT revealed a decrease in the size and vascularity of the lung metastases, except for 1 nodule that persisted with marked contrast enhancement and developed a communication with a pulmonary artery and vein...

The present report describes a case of an acquired uterine arteriovenous fistula, which, following surgery and postoperative pathological analysis, was confirmed as a previous cornual pregnancy with placenta accreta. The patient was a 37-year-old woman (gravida 3; para 2) who had previously delivered two children via cesarean section (in 2004 and 2010, respectively) and also had a spontaneous abortion (2008). She had experienced continuous menstrual bleeding for ~20 days and had a history of prolonged (~30 days) vaginal bleeding 13 months earlier...

Dysfunctional uterine bleeding is a common presentation of women in the emergency department. We describe the case of a 33-year-old female who presented with intermittent spotting due to an acquired uterine AVF. The patient underwent a transvaginal pelvic ultrasound as well as a CT angiogram. The patient was treated conservatively and elected to undergo uterine artery embolization in an effort to preserve fertility. She successfully delivered a healthy baby boy at 39-week gestation via an emergent caesarian section due to a prolapsed umbilical cord 17 months after undergoing the uterine artery embolization...

Gestational trophoblastic disease (GTD) is a spectrum of both benign and malignant gestational tumors, including hydatidiform mole (complete and partial), invasive mole, choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor. The latter four entities are referred to as gestational trophoblastic neoplasia (GTN). These conditions are aggressive with a propensity to widely metastasize. GTN can result in significant morbidity and mortality if left untreated. Early diagnosis of GTD is essential for prompt and successful management while preserving fertility...

Arteriovenous malformations (AVMs) are a rare source of potentially life-threatening uterine bleeding, and should be suspected in patients presenting with metromenorrhagia. Histologically, AVMs are characterized as having both arterial and venous tissues without an intervening capillary network.1 The etiology may be either congenital or acquired secondary to prior uterine surgery or uterine malignancy.2 Congenital lesions are thought to result from arrested vascular development and contain a nidus of multiple feeding arteries anastomosed to multiple draining veins...

A uterine arteriovenous malformation (AVM) is an uncommon cause of uterine bleeding. Location of this lesion in the uterine cervix is exceptional. We report a case of a 34-year-old woman who presented with chronic menorrhagias and hypochromic anemia. A sonographic study revealed a 10-cm, fundal, intramural, uterine well-circumscribed mass that distorted the endometrial cavity. The patient underwent hysterectomy for a large uterine leiomyoma. The pathological study revealed an incidental AVM of the posterior half of the cervix measuring 5...

The advent of interventional radiology enabled remarkable advances in diagnosis and treatment of several situations in obstetrics and gynecology. In the field of obstetrics, these advances include temporary occlusion of the iliac arteries to the management of placenta accreta and/or prior, arteriovenous fistulas after embolization of uterine curettage and management of ectopic uterine and extra-uterine pregnancies. The non-tubal ectopic pregnancy, either cervical, abdominal, ovarian or in a cesarean scar, often represents major therapeutic challenge, especially when exists a desire to maintain fertility...

Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH. TAE allows stopping the bleeding in 90 % of women with severe PHH, obviating surgery. Pledgets of gelatin sponge as torpedoes are commonly used for safe TAE, and coils, glue, and microspheres have been primarily used in specific situations such as arterial rupture, pseudoaneurysm, and arteriovenous fistula...

Vascular Ehlers-Danlos Syndrome (VEDS), previously called Ehlers-Danlos syndrome type-IV, is a heterogeneous group of heritable connective tissue disorders characterized by thin, translucent skin, easy bruising, arterial, intestinal, and/or uterine fragility. There is large vessel involvement that leads to arterial rupture often preceded by aneurysm, arteriovenous fistulae, or dissection. Noninvasive imaging studies such as CT angiography and MR angiography are preferred as diagnostic studies for this condition...

We present two cases of acquired uterine arterial venous malformation (AVM) which was diagnosed because of massive genital bleeding successfully treated with transcatheter arterial embolization (TAE), using N-butyl-2-cyanoacrylate (NBCA) under balloon occlusion. Balloon occlusion at the uterine artery was performed in both patients for diffuse distribution of NBCA in multiple feeding branches, as well as to the pseudoaneurysm, and for the prevention of NBCA reflux. In one of our patients, balloon occlusion of the draining vein was simultaneously performed to prevent NBCA migration through accompanying high-flow arteriovenous fistula (AVF)...

Arteriovenous fistula is any abnormal connection between an artery and a vein that bypasses the normal capillary bed and shunts arterial blood directly to the venous circulation. Uterine arteriovenous fistula (UAVF) is a potentially life-threatening condition by causing massive bleeding. This report describes a case of UAVF with massive hemorrhage. Prior to surgery, endovascular catheters for balloon occlusion were placed within bilateral uterine arteries. During surgery, the surgeon requested temporary balloon inflation for navigating and identifying inflow arteries...

OBJECTIVE: To report our experience on the value of dynamic three-dimensional computerized tomographic (CT) angiography for immediate diagnosis and management of intractable postpartum hemorrhage (PPH). STUDY DESIGN: Retrospective study of all cases of PPH examined by three-dimensional CT angiography between January 2007 and August 2013 in a single center. In each case, emergency dynamic CT was taken at the early arterial, late arterial and venous phases to identify the extravasated contrast agent that represents active hemorrhage...

Post-partum haemorrhage is a major determinant of maternal mortality. Traditionally, cases of post-partum haemorrhage caused by arterial injuries were managed by caesarean hysterectomies or bilateral internal iliac artery ligations. The diagnosis of aneurysms or arteriovenous malformations of uterine artery are often missed. Uterine curettage, caesarean section or vaginal delivery can result in uterine vascular anomalies like pseudo aneurysms, arteriovenous malformations, arteriovenous fistula and rupture of uterine vessels...

BACKGROUND: Acquired arteriovenous malformations (AVMs) can develop after uterine instrumentation. The increased risks of vascular changes, including abnormal placentation, after repeated cesarean sections are well studied. Herein, we describe a patient with delayed hemorrhage from a uterine AVM, following dilation and curettage for a cesarean scar pregnancy. CASE: A 32-year-old G3P2 presented with a cesarean scar ectopic pregnancy managed with dilation and curettage, which incurred a 1,500-ml blood loss...

Vaginal bleeding is not uncommon in the first trimester of pregnancy. Ultrasound is the foremost modality for evaluating normal development of the gestational sac and embryo and for discriminating the causes of bleeding. While correlation with quantitative βHCG and clinical presentation is essential, sonographic criteria permit diagnosis of failed pregnancies, ectopic pregnancy, gestational trophoblastic disease and spontaneous abortion. The American College of Radiology Appropriateness Criteria guidelines have been updated to incorporate recent data...

Uterine arteriovenous malformation (AVM) can be congenital or acquired. When acquired (e.g., fistula), it results from abnormal arteriovenous communication between one or more uterine arteries and a myometrial and/or endometrial venous plexus, without the interposition of a vascular nidus. Arteriovenous malformation is composed of a tortuous net of fragile low-resistant arteriovenous shunts. Other arteries can be involved in fistulas, including ovarian arteries or those from the round ligaments of the uterus, in particular in congenital AVMs, which develop from failure in embryologic differentiation that leads to multiple abnormal vascular connections...

Uterine arteriovenous fistula (AVF) is a rare entity, but may lead to life-threatening hemorrhage. Although transcatheter embolization, surgical ligation, or hysterectomy would be considered for treatment of uterine AVF, there is poor knowledge as to how gynecologists can manage the uterine AVF with multiple large inflow arteries. Herein we report a uterine AVF successfully treated using multiple-step transcatheter embolization. The patient, a 58-year-old postmenopausal woman with a history of dilation and curettage, had intermittent massive uterine bleeding...
