ABSTRACT Aim The object of this study was to analyze the vascularization index of three-dimensional (3D) power Doppler ultrasound (PDUS) of the placenta in severe pre-eclampsia compared with normal pregnancy conditions by vascular biopsy sampling sphere. Subjects and methods This study is a prospective longitudinal observational study on 80 pregnant women which divided into 2 groups: Group I (study group) were 40 pregnant women with severe pre-eclampsia, group II (control group) were 40 pregnant women without disorder. Variables examined in this study were vascular index (VI), flow index (FI) and vascular flow index (VFI) of the 3D-PD placental perfusion. Its correlation to gestational age in normal pregnancy compared with the condition of preeclampsia were obtained by taking multiple biopsy sampling vascular sphere. All pregnant women underwent 3D PD-US examination (single examination only), data volume recorded of the placenta allows for off-line analysis without the presence of the patient, thus allowing the data analysis done anywhere and anytime by observers for the comparative analysis of interobserver reliability. Results The placenta can be visualized perfectly in both of the study group and also the control group. Average Kappa value for the acquisition of placental vascularization index measurements with 3D PD-US was 0.72 (0.61-0.82), 0.73 (0.65-0.82) and 0.71 (0.61-0.81) for VI, FI and VFI in the range of 20 to 38 weeks showed good interobserver reliability. All 3D power Doppler indices had a significant association with gestational age, with VI showed a less significant relationship (r = 0.207, p = 0.0139) and FI has the most significant relationship (r = 0.582, p < 0.001). FI index increased progressively with gestational age, while the VI index values indicate dispersion pattern and reached a plateau from week 30 onwards. Entering week 37th, there was a decrease in the value of the index VI until the end of pregnancy. Meanwhile, VFI index appears to resemble the pattern of a combination of both VI and FI index (r = 0.692, p <0.001). Conclusion All parameters of 3D power Doppler index was lower in the severe pre-eclampsia compared with normal pregnancy. 3D PD-US can be used to assess the vascularization of the placenta and the intensity of intra-placental blood flow. Placental vascular biopsy method is fairly efficient way to perform routine evaluations evolution of placental vascular branch during pregnancy.

The objective of the present study was to evaluate fetal cerebral circulation by using three-dimensional (3D) power Doppler ultrasound in normal and growth-restricted fetuses. A total of 100 normal grown fetuses were compared with other 25 with growth restriction (FGR). Three-dimensional power Doppler ultrasound was used to assess fetal cerebral 3D vascular indices: vascularization index, flow index (FI), and vascularization flow index (VFI). Both FI and VFI correlated positively with gestational age. On average, all the 3D vascular indices were increased in fetuses with FGR. The proportion of fetuses detected as having hemodynamic redistribution was higher when using 3D power Doppler indices than by means of the middle cerebral artery pulsatility index (52% versus 20%, P = 0.002). In conclusion, two of the three indices increased during gestation. All the fetal cerebral 3D vascular indices are increased in fetuses with FGR. In these fetuses, there were more cases suggesting hemodynamic redistribution than expected by conventional Doppler studies.

Uterine Septum

Abstract Background Uterine anomalies are a relatively common congenital abnormality, with uterine septum being the most common. This is even truer in patients with recurrent pregnancy loss, in whom rates of uterine abnormalities may approach 15% to 27%. Historically, the uterine septum has been approached via laparotomy through either a Tompkins or Jones procedure. These successful, but highly morbid, procedures require laparotomy with significant hospital stays, subsequent cesarean delivery, and have carried a high risk of adhesion formation. More recently, this surgery has been supplanted by hysteroscopy or other minimally invasive methodologies. Objective To assess the relation between the vascularity of uterine septum and obstetric performance with Transvaginal 3D Power Doppler Ultrasound. Patients and Methods Early Cancer Detection Unit and Ultrasound and Fetal special care Unit in Ain Shams University Maternity Hospital (ASUMH). Recruitment took place between May 2017 and November 2018. Cross-sectional study. The study included 30 cases of women with uterine septum. Intervention: Transvaginal 3D power Doppler ultrasound was done to all cases with septal volume and vascularity assessment using VOCAL system and Histogram facility. The study included 30 patients with septate uterus, twelve of them suffered from 1ry infertility while the other eighteen suffered from recurrent abortion. Results There was statistical significant difference between the two groups regarding vascularity (VI, FI, and VFI) of septum (P &lt; 0.05). Conclusion The vascularity of septate uterus is variable. The power Doppler indices shows that septate uterus in cases with recurrent abortion is highly vascular while in cases with 1ry infertility shows low vascularity. Highly vascular septum may be a site of implantation which may be a cause of recurrent abortion thus; excision of the septum may help prevent recurrent abortion, while low vascular septum may prevent implantation which may be a cause of infertility thus; incision of the septum may help in treatment of infertility. Correlation with histopathologic features of septum may be required to decide the best management of the septum.
