Abstract
Objective: Placental chorioangioma is the most common non-trophoblastic vascular benign tumor of the placenta, with an estimated incidence of 1% of all pregnancies. Most chorioangiomas are small asymptomatic lesions that are found incidentally only postnatally during histologic examination of the placenta. Voluminous chorioangiomas (>4–5 cm), however, are less common and are more often diagnosed prenatally, through ultrasound imaging. Color Doppler demonstrates either a single blood vessel feeding the lesion or substantial vascularity within the mass. Large tumors have been associated with multiple adverse perinatal outcomes, including fetal growth restriction, preterm birth, polyhydramnios, fetal congestive heart failure, fetal anemia, fetal hydrops and intrauterine death. Case(s): A 35-years-old primigravida woman with uncomplicated pregnancy was referred to the Ultrasound Centre of Obstetric and Gynecologic of Sant’Anna Hospital, Turin, due to a suspect placental mass seen during the ultrasound performed at 32 weeks of gestation. In this case, detailed ultrasound scans with grey scale and Doppler examination were performed (using Aplio 550; Canon Medical Systems Europe BV, Zoetermeer, The Netherlands). We also decided to study the vascularization of the mass with SMI (superb microvascular imaging) technology. In particular, with the use of SMI, it was possible to visualize the vascularization of the mass more completely which was conspicuous at first but disappeared after thrombosis of feeding vessels with favorable pregnancy outcome. Conclusion: SMI is a new vascularity imaging method that can visualize vessels that exhibit slow flow rates. It uses a system to reduce artifacts by greatly reducing interference from tissue movement.
期刊介绍:
The Journal of Perinatal Education (JPE) is the leading peer-reviewed journal specifically for childbirth educators. Through evidence-based articles, the JPE advances the knowledge of aspiring and seasoned educators in any setting-independent or private practice, community, hospital, nursing or midwifery school-and informs educators and other health care professionals on research that will improve their practice and their efforts to support natural, safe, and healthy birth. The JPE also publishes features that provide practical resources and advice health care professionals can use to enhance the quality and effectiveness of their care or teaching to prepare expectant parents for birth. The journal''s content focuses on pregnancy, childbirth, the postpartum period, breastfeeding, neonatal care, early parenting, and young family development. In addition to childbirth educators, the JPE''s readers include nurses, midwives, physicians, and other professionals involved with perinatal education and maternal-child health care.
