...Catherine Hamzeh; Jessica Green; Grace Hamadeh; Lisa M. Korst; Ramen H. Chmait Introduction: To compare the blood volume transfused for fetal anemia in cases of placental chorioangioma versus red blood cell (RBC) alloimmunization in patients matched for gestational age (GA) and hydrops. Methods...

...Hanane Bouchghoul; Alexandra Benachi; Marie-Victoire Senat Introduction: In Doppler flow diagnosis of a large placental chorioangioma with vascularization, there may be fetal consequences as cardiac output failure and polyhydramnios. Prenatal percutaneous fetoscopic laser photocoagulation...

... embolization. This case series describes our technique and supports microcoil embolization as a potentially safe and effective antenatal treatment option in symptomatic chorangiomas. Placental chorangioma Chorioangioma Microcoil embolization Fetal anemia high-output cardiac failure Placental...

...Hian Yan Voon; Rafaie Amin; Juan Loong Kok; Kia Sing Tan We illustrate a case of giant placental chorioangioma presenting at 20 weeks of gestation. Subsequent monitoring revealed enlargement of the lesion, associated with fetal anemia and cardiac failure, prompting in utero intervention...

...Yvonne Kwun Yue Cheng; Simon Chun Ho Yu; Po Lam So; Tak Yeung Leung We describe a case of large chorioangioma diagnosed at 22 weeks of gestation. As the tumour progressively enlarged to 8 cm with fetal cardiomegaly and increased middle cerebral arterial peak systolic velocity, embolisation of its...

Radiofrequency ablation Placental tumor Chorioangioma Radiofrequency (RF) ablation is a method of tissue coagulation by using a unique electrical frequency of approximately 500 kHz. This frequency is equivalent to the range...

.... Intrauterine transfusion (IUT) treatment is considered most successful for fetal anemia due to red cell alloimmunization. Moreover, the use of this procedure has also been reported in pregnancies with parvovirus B19 infection, fetomaternal hemorrhage and placental chorioangiomas, for example. This review...

...Cinzia Zoppini; Barbara Acaia; Gina Lucci; Lorenza Pugni; Beatrice Tassis; Umberto Nicolini Three cases of placental chorioangiomas, from 6.5 to 10 cm in diameter, were diagnosed prenatally by ultrasound and color Doppler imaging at 21–34 weeks of gestation. In 1 case, due to fetal hydrops...

...Claude D’Ercole; Ludovic Cravello; Leon Boubli; Corinne Labif; Véronique Millet; Alain Potier; Bernard Blanc A large chorioangioma located at the insertion area of the umbilical cord was diagnosed at 19 weeks of gestation by ultrasound and color Doppler ultrasound. This chorioangioma led...

...Esra Arun Ozer; Nuray Duman; Abdullah Kumral; Sebnem Yilmaz; Hale Oren; Mustafa Kir; Erdener Ozer; Hasan Ozkan Although chorioangiomas are the most common placental tumors, multiple chorioangiomas (or chorioangiomatosis) are extremely rare. We report a female newborn at 37 weeks of gestation...

...Ozgur Deren; Ozgur Ozyuncu; Lutfu S. Onderoglu; Tekin Durukan Chorioangiomas are usually small, clinically inevident, benign vascular lesions of the placenta, but larger ones may cause serious perinatal and neonatal complications. There is need for in utero intervention in these fetuses. Several...

...D. Escribano; A. Galindo; J. Arbués; J.M. Puente; P. De la Fuente Placental chorioangiomas are benign tumors of the placenta. Large chorioangiomas may cause severe complications such as fetal anemia, hydrops and fetal death. We report the use of sonographic findings and peak systolic velocity...

... case of recurrent multiple chorioangiomas. Methods: Complementary deoxyribonucleic acid array analysis was performed on the affected placentae and on normal placentaes (controls) to compare messenger ribonucleic acid levels of 96 genes involved in angiogenesis. Results: Eleven genes presented more than...
