OBJECTIVES The purpose of this study was to estimate the prevalence and persistence rate of vasa previa in at-risk pregnancies using a standardized screening protocol. METHODS We conducted a descriptive study of patients with a diagnosis of vasa previa from a single ultrasound unit between June 2005 and June 2012. Vasa previa was defined as a fetal vessel within 2 cm of the internal cervical ...
Vasa previa is a rare but clinically important obstetrical complication that can be associated with a low-lying placenta or placenta previa. We aim to convey the challenges in diagnosing this condition by presenting 2 cases of pseudo vasa previa diagnosed antenatally as vasa previa using standard and color Doppler ultrasonography. Both patients were falsely diagnosed; only a low-lying placenta ...
Introduction: Vasa previa is an uncommon obstetrical complication that poses a high risk of fetal demise if not recognized before rupture of membranes. It is vital that providers recognize risk factors for vasa previa and diagnose this condition before the onset of labor so that fetal shock or demise is prevented. Methods: We report a patient with a bilobed placenta and perinatal hemorrhage cau...
Maternal history of vasa previa across gestation using a screening protocol Rebarber A, Dolin C, Fox N, Klauser C.K, Sultzman DH, Roman AS Journal of Ultrasound in Medicine 2014; 33: 141 –47 From a total of 27,573 patients, vasa previa, defined as a fetal vessel within 2 cm of the internal cervical os on transvaginal sonography, was seen in 31 cases. This gives an incidence of 1.1 per 1000. Twe...
Vasa previa is a rare but clinically important obstetrical complication that can be associated with a low-lying placenta or placenta previa. We aim to present one case of vasa previa diagnosed during the placenta examination after the caesarean indicated for triple uterus scar. A 26-year-old female was referred to our hospital at 30 weeks of gestation to provide a scheduled caesarean. Trans-abd...
OBJECTIVES To describe the etiology of vasa previa and the risk factors and associated condition, to identify the various clinical presentations of vasa previa, to describe the ultrasound tools used in its diagnosis, and to describe the management of vasa previa. OUTCOMES Reduction of perinatal mortality, short-term neonatal morbidity, long-term infant morbidity, and short-term and long-term ...
Effective management of vaginal bleeding in late pregnancy requires recognition of potentially serious conditions, including placenta previa, placental abruption, and vasa previa. Placenta previa is commonly diagnosed on routine ultrasonography before 20 weeks' gestation, but in nearly 90 percent of patients it ultimately resolves. Women who have asymptomatic previa can continue normal activiti...
Vasa previa, defined as fetal vessels coursing within the membranes between the presenting part and the cervix, occurs in approximately 1:2500-5000 pregnancies. Type II vasa previa consists of fetal vessels crossing over the internal os connecting a bilobed placenta or a succenturiate lobe with the main placental mass. These vessels are prone to compression during labor or may tear when membran...
Velamentous cord insertion and vasa previa can impair the fetal growth. This pathology occurs either in singleton or more often in monochorionic (MC) twin pregnancies where it can accompany the selective intrauterine growth retardation (sIUGR). This condition is related to increased fetal mortality and morbidity especially due to a very high risk of vessel rupture. Transvaginal ultrasound scree...
