Aims and objectives
The gravid uterus is supplied by anastomoses between the left and right uterine arteries and the ovarian arteries.The contribution of these vessels to placental blood flow depends on placental location and placental-side indices have been reported to be lower placental vessels in laterally located placentas.[2-4]Non-central placental location has also been reported to be associated with increased adverse peri-natal outcomes,
and even post partum...
Methods and materials
Study Design:This was a prospective study of uterine artery Doppler US parameters in healthy pregnant women.
The data was collected over 12 months,
between July 2016 to June 2017. Study Site: This study was conducted at Braithwaite Memorial Specialist Hospital (BMSH),
a tertiary hospital located in Port-Harcourt city,
the capital of Rivers state in southern Nigeria. The BMSH provides care to over 1.9 million inhabitant of the city and its outskirts. Study Population: included one hundred and...
The demographic characteristics of the one hundred and seventy (170) participants are summarized in table 1. Seventy eight (78) women had a centrally located placenta (Group A) while 92 had a laterally located placenta ( Fig. 2 ). Mean gestational age at recruitment was 22 weeks for group A and 21 weeks for group B.
There were no significant differences between the age,
BMI and parity between both groups. Seven (8.9%) of women in group A developed PrE compared to 6 (6.5%)...
There was a slightly higher prevalence of PrE in subjects with central placenta (9% vs 7%),
but we found no significant association between placental location and PrE X 2 =0.096,
This is similar to the findings by Salama et al and Contro and his colleagues .
Seckin et alhowever reported that PrE was significantly higher in patients with lateral placenta compared to those with central placentas( 4.5% vs.
1.6%; p = 0.027). This difference may be due to the fact that most...
