Abstract:
Moreover, the first trimester ultrasonography provides a valuable e valuation for predicting pregnancy outcomes. Our purpose was to determine whether ultrasonography of placental location at 11 - 14 weeks of gestation (first trimester) can predict neonatal and maternal pregnancy outcomes. The observational and prospective st udy from July 2011 to October 2012 was conducted on the 200 pregnant women with previous cesarean. Placental locations were determined by ultrasonog raphy at 11 - 14 weeks’ gestation, and then were classified into four groups including anterior high , anterior low , posterior high and posterior low. Parameters such as Preterm Labor, Preterm Premature Rupture of Membrane , neonatal Birth Weight , occurrence of bleeding throughout pregnancy were followed up. Our results showed that the anterior low group had highest rate of bleeding throughout pregnancy compared with groups of posterior low, anterior high and posterior high (40 %, 34 %, 4 %, 6 %, respectively, p < = 0.001); furthermore, there was significant correlation between rising the number of previous cesareans and increasing the incidence of the anterior low placental implantation (P value = 0.03). Anterior low group had lowest average of neonatal birth weight (p - value < 0.001), while anterior high group had highest average of neonatal birth weight compared wit h other groups. We believe that the ultrasound procedure was valid and enabled us to evaluate the pregnancies at first stages of pregnancy (11 - 14 weeks ) . Therefore, it can be used in evaluating the pregnancies to categorize them as being at risk for an adv erse ante partum, intra partum and neonatal outcomes.Keywords:

Most placenta-related pregnancy complications have an origin in very early pregnancy. We aim to investigate associations between first trimester placental growth trajectories, i.e. placental volume (PV) and placental vascular volume (PVV), and maternal and neonatal pregnancy outcomes. In the Virtual Placenta study, embedded in a tertiary hospital population of the ongoing Rotterdam periconception cohort, we included 241 pregnant women before 8 weeks gestational age (GA). Three dimensional ultrasound examinations, including power Doppler techniques, at 7, 9 and 11 weeks GA were performed to obtain volumes for off-line measurements. PV and PVV were measured using Virtual Organ Computer-Aided Analysis™ and Virtual Reality software, respectively. To study the associations between placental growth trajectories and placenta-related pregnancy complications, linear and logistic regression analyses were performed including adjustments for uterine artery (UtA) Doppler indices. A total of 214 ongoing pregnancies were included of which 41 (17%) developed a maternal or neonatal placenta-related pregnancy complication. Crude and adjusted for UtA Doppler indices, PV was positively associated with any of these complications (OR 0.97, CI 0.94-1.00, p = 0.042). The slopes of PV and PVV were positively associated with BW (β = 963 grams, CI 373-1553, p = 0.002 and β = 1126 grams, CI 160-2090, p = 0.022, respectively). The slope of PV remained significant after adjustment (β = 797 grams, CI 193-1399, p = 0.010). Significant associations between PV and maternal and neonatal placenta related pregnancy complications were only observed in pregnancies with a male fetus. First trimester placental growth trajectories are associated with maternal and neonatal placenta-related pregnancy complications with modification of gender of the embryo. Further research is needed to confirm these findings and to investigate the clinical relevance for newborn health.

First-trimester vaginal bleeding occurs in as many as 25% of pregnancies. Does this event predict other pregnancy complications? In a retrospective cohort study, Danish investigators evaluated the association between first-trimester bleeding and risk for complications later in the same pregnancy or in a second pregnancy. Data were extracted …

ABSTRACT Second‐trimester tubal pregnancy is rarely encountered and published cases are limited. There are no established sonographic criteria to differentiate it from abdominal pregnancy; however, differences in their medical management make this distinction important. We report a case of a 14‐week 5‐day tubal pregnancy that presented near rupture. Sonography demonstrated many overlapping features with abdominal pregnancy. In addition, the extrauterine gestational sac was rounded and well defined and the placenta was crescent‐shaped. We propose that these sonographic features represent a second‐trimester tubal pregnancy rather than an abdominal pregnancy. © 2013 Wiley Periodicals, Inc. J Clin Ultrasound 42 :162–168, 2014

In patients presenting for an evaluation of pregnancy in the first trimester, transvaginal ultrasound is the modality of choice for establishing the presence of an intrauterine pregnancy; evaluating pregnancy viability, gestational age, and multiplicity; detecting pregnancy-related complications; and diagnosing ectopic pregnancy. In this pictorial review article, the sonographic appearance of a normal intrauterine gestation and the most common complications of pregnancy in the first trimester in the acute setting are discussed.

Placenta increta complicating pregnancy in the first trimester is rare. A patient with risk factors for placenta increta required a hysterectomy to control a hemorrhage after a first-trimester abortion. Pathologic study confirmed the preoperative diagnosis of placenta increta.
