We present two case reports of twin reversed arterial perfusion sequencea rare type of twin-twin transfusion syndrome wherein there is abnormal development of one fetus which derives its blood supply from the normal fetus. It is present in cases of monochorionic twin pregnancies and is also known as chorangiopagusparasiticus. Prompt diagnosis and intervention are needed to prevent the death of ...

BACKGROUND We examined the perinatal outcomes in cases of at least one fetal demise in monochorionic and diamniotic twin pregnancies. METHODS We reviewed the obstetric records of all Japanese twin pregnancies managed beyond 9 weeks' gestation at Japanese Red Cross Katsushika Maternity Hospital between 2008 and 2014. RESULTS The incidence in the monochorionic twin pregnancies was significant...

Background: Prediction of adverse perinatal and postnatal outcomes could be possible by using ultrasound Doppler evaluation, however there are some controversies regarding this issue in the literature. The goal of present study was to evaluate predictive value of Doppler indices in single and twin pregnancies during second trimester. Materials and Methods: This prospective study was conducted i...

The study comprises 889 pregnant women between 14 and 21 weeks of gestation. The control group consisted of 862 pregnant women with unburdened obstetric anamnesis with an uneventful singleton pregnancy. The examined group consisted of 27 pregnant women with uncomplicated twin pregnancy. In the sera of pregnant women AFP (Microparticle Enzyme Immunoassay AxSYM Abbott), total beta-hCG (Microparti...

Acardiac-acephalic twin is one of the bizarre complications of monozygotic, monochorionic twin pregnancies. It is commonly referred to as Twin Reversed Arterial Perfusion (TRAP) sequence, in which the primary malformation is the lack of a well -defined cardiac structure in one twin (acardiac), which is kept alive by its structurally normal co-twin (pump twin) through abnormal placental vascular...

OBJECTIVE To assess the maternal endothelial function in normal twin pregnancy. DESIGN Cross-sectional study. SUBJECTS Endothelial function was investigated in 74 women with normal twin pregnancy at 11-30 weeks of gestation and the results were compared to previous reported findings in 98 women with normal singleton pregnancy and 19 non-pregnant controls. METHODS Endothelial function was ...

OBJECTIVE To assess prospectively the diagnostic reliability and prognostic significance of prenatal diagnosis of cytomegalovirus (CMV) infection. METHODS One hundred ten pregnant women (four with twin pregnancies) with a risk of congenital CMV infection were investigated. Prenatal diagnosis was carried out by amniocentesis and fetal blood sampling (n = 75) or amniocentesis alone (n = 35). Se...

Ultrasound determination of chorionicity is most reliable before 14 weeks and subsequently reduces in accuracy with advancing gestation. The aim of this study was to evaluate the accuracy of chorionicity determination in a birth cohort of twin pregnancies. Antenatal ultrasound determination of chorionicity in twin pregnancy was undertaken at suboptimal period of gestation in over twothirds of t...

Uterine torsion is the 45° rotation of the uterus around its longitudinal axis. The incidence of uterine torsion is higher in patients with uterine fibroma, adnexal tumors, intra-abdominal adhesions, twin pregnancy. Diagnosis is difficult to make due to the noncharacteristic symptomatology. Most frequently, the clinical picture includes abdominal pain, digestive symptoms, and urinary symptoms. ...
