First-Trimester Placental and Myometrial Blood Perfusion Measured by Three-Dimensional Power Doppler in Preeclampsia

ABSTRACT Implantation of the zygote outside the uterine cavity occurs in 2% of all pregnancies. The rate of ectopic pregnancies has increased from 0.5% in 1970 to 2% today. The prevalence of ectopic pregnancy in all women presenting to an emergency department with first-trimester bleeding, lower abdominal pain or a combination of the two is between 6 and 16%. When diagnosis is made early, the product of conception can be removed safely by laparoscopic surgery and be submitted for histological examination. Tubal rupture is a complication of late diagnosed tubal pregnancy which is more difficult to treat conservatively and often indicates tubectomy or segmental resection. In 5 to 15% of treated ectopic pregnancy cases, remnant conception product parts are diagnosed and may require a final methotrexate (MTX) injection. Rare sites of ectopic pregnancy include interstitial, cervical, abdominal and cesarean scar pregnancies. Our manuscript reviews and illustrates the use of novel sonographic methods such as three-dimensional ultrasound, multiplanar view, in combination with color and power Doppler ultrasound, for early detection of ectopic tubal pregnancy and of other, rare locations of ectopic pregnancy.

Diagnostic Modality

Background. Conventional sonography is the primary imaging tool for these pregnant women who present with an ovarian teratoma. In some cases, however, sonography diagnosis is difficult. We report a case of ovarian teratoma during pregnancy diagnosed by three-dimensional Power Doppler. The cyst was removed via laparotomy without fetal or maternal complications. Three-dimensional ultrasound with multiplanar view can better discriminate a benign ovarian teratoma from complex ovarian lesions or malignant tumors. Its role is significant especially during pregnancy as it may assist in determining which patients are requiring surgery and which are not. The results of three-dimensional sonography and magnetic resonance (MR) were equal but the role of MR imaging is limited in early pregnancy.Conclusions. Three-dimensional technique is a reliable diagnostic modality for preoperative assessment of an ovarian teratoma as it can be performed during the first trimester of pregnancy.

Singleton Pregnancies

This prospective observational study aimed to compare the changes in placental vascular indices and placental volume using three-dimensional power Doppler (3DPD) ultrasound in pregnancies with small for gestational age (SGA) neonates. We enrolled 396 women with singleton pregnancies from September 2013 to June 2016. Placental vascular indices, including the vascularization index (VI), flow index (FI), and vascularization flow index (VFI), and placental volume were obtained using 3DPD ultrasound in the first and second trimesters. Of the enrolled women, 21 delivered SGA neonates and 375 did not. In the first trimester, the SGA group had a significantly lower mean FI (25.10 ± 7.51 versus 33.10 ± 10.97, p < 0.001) and VFI (4.59 ± 1.95 versus 6.28 ± 2.35, p = 0.001) than the non-SGA group. However, there was no significant difference in the placental volume between the two groups during the first trimester. In the second trimester, the SGA group also had a significantly lower mean FI (27.08 ± 7.97 versus 31.54 ± 11.01, p = 0.022) and VFI (6.68 ± 1.71 versus 8.68 ± 3.09, p < 0.001) than the non-SGA group. In addition, a significantly smaller placental volume was noted in the SGA group (104.80 ± 24.23 cm3 versus 122.67 ± 26.35 cm3, p = 0.003) than in the non-SGA group during the second trimester. The results showed that a decreased placental VFI occurred earlier than a decreased placental volume in SGA pregnancies.
