    Applicability of fetal renal artery Doppler values in determining pregnancy outcome and type of delivery in idiopathic oligohydramnios and polyhydramnios pregnancies
    (Via Medica, 2013) Akin, Ibrahim; Uysal, Ahmet; Uysal, Fatma; Oztekin, Ozgur; Sanci, Muzaffer; Gungor, Aysenur Cakir; Kurtulmus, Secil
    Aims: To investigate the relationship between fetal renal artery Doppler results and pregnancy outcomes in patients with idiopathic abnormal amniotic fluid indices. Material and method: A total of 110 patients without signs of fetal distress were included in the study: 31 idiopathic oligohydramnios and 29 idiopathic polyhydramnios pregnancies (study group) and 50 normal pregnancies (controls). Doppler investigation of the umbilical artery (UA), middle cerebral artery (MCA), fetal descendant thoracic aorta (DTA) and fetal renal artery (RA) was performed in all patients. Fetal RA resistive index (RI) and pulsatile index (PI) values were measured. Values pertaining to type of birth, newborn weight and APGAR scores were compared. Results: Average patient age, gravidity and week of pregnancy were 25 +/- 4, 1.6, and 37.4 +/- 1, respectively. There were no statistically significant differences between the groups as far as UA S/D, MCA S/D, DTA S/D, DTA RI, DTA PI, and RA S/D measurements were concerned. However, in the oligohydramnios group RA RI and RA PI values were significantly higher than the other two groups. Birth weight in the polyhydramnios group and cesarean section rate due to fetal distress in the oligohydramnios group were significantly higher. Conclusions: In the oligohydramnios group, without affecting fetal distress parameters, Doppler USG evaluation identified an increase in the RA resistance. Also in that group, cesarean rate due to fetal distress during labor was significantly higher than in the remaining two groups. Due to the predictive potential of values of fetal renal artery Doppler of fetal outcome further large sample-sized studies on the subject ought to be carried out.

    Prenatal Diagnosis of Teratoma of The Neck By Using 2 and 3 Dimensional Ultrasound; A Case Report
    (Derman Medical Publ, 2013) Uysal, Fatma; Kurtulmus, Secil; Uysal, Ahmet
    Teratomas originate from the 3 germ layers, the endoderm, mesoderm and ectoderm, with varying rates of involvement. Congenital teratoma, observed in approximately 1:20.000-40.000 live births, are very rarely located in the area of the head and neck and the majority are benign malformations. The main cause of morbidity and mortality from cervical teratoma is the tumor size and its compression of the airway. This pathology may require emergency intervention postpartum and if not treated mortality-morbidity may be high. As a result prenatal diagnosis and monitoring is very important. Here we present the case of a cervical teratoma, prenatally diagnosed on 2- and 3-D (dimensional) ultrasound, which required an emergency operation postpartum due to development of respiratory distress.

    Prenatal Ultrasonography in the Diagnosis of Vein of Galen Aneurysmal Malformation
    (Derman Medical Publ, 2013) Uysal, Fatma; Kurtulmus, Secil; Uysal, Ahmet
    The vein of Galen aneurysmal malformation (VGAM) is a rarely-seen congenital intracranial arteriovenous shunt characterized by an abnormal direct relationship between one or more cerebral arteries and the vein of Galen. While the causes of VGAM are not fully known, the hypothesis advocated is that it is due to persistence of embryonic vascular support causing progressive dilatation of the aneurysm. It can be diagnosed by prenatal ultrasonography. Together with extremely high-flow intracerebral shunt and differing degrees of pulmonary hypertension, high-output heart failure linked to volume increases may occur. Current treatment choice is endovascular treatment which if administered in the early period before heart failure develops may be life-saving. For this reason, prenatal diagnosis of this multidisciplinary treatment approach requiring situation, is important. Here, we present a 28-year-old woman at 33 weeks' gestation who was evaluated using B-mode and color Doppler sonography for the prenatal diagnosis of VGAM.
