“…Prenatal sonographic diagnosis of succenturiate (and bilobate) placenta, both similarly potential predisposing factors for vasa previa, have been reported. [126][127][128][129][130] Sonographic findings of these similar entities are rather straightforward and consist of the notation of placental tissue without continuity (occupying areas at a distance from each other) yet connected by fetal vasculature.…”

The umbilical cord constitutes a continuation of the fetal cardiovascular system anatomically bridging between the placenta and the fetus. This structure, critical in human development, enables mobility of the developing fetus within the gestational sac in contrast to the placenta, which is anchored to the uterine wall. The umbilical cord is protected by unique, robust anatomical features, which include: length of the umbilical cord, Wharton's jelly, two umbilical arteries, coiling, and suspension in amniotic fluid. These features all contribute to protect and buffer this essential structure from potential detrimental twisting, shearing, torsion, and compression forces throughout gestation, and specifically during labor and delivery. The arterial components of the umbilical cord are further protected by the presence of Hyrtl's anastomosis between the two respective umbilical arteries. Abnormalities of the umbilical cord are uncommon yet include excessively long or short cords, hyper or hypocoiling, cysts, single umbilical artery, supernumerary vessels, rarely an absent umbilical cord, stricture, furcate and velamentous insertions (including vasa previa), umbilical vein and arterial thrombosis, umbilical artery aneurysm, hematomas, and tumors (including hemangioma angiomyxoma and teratoma). This commentary will address current perspectives of prenatal sonography of the umbilical cord, including structural anomalies and the potential impact of future imaging technologies.

“…The confirmation of diagnosis of this anomaly often occurs at birth, on visual inspection of the placenta, with only a few cases successfully diagnosed antenatally on ultrasound 11. In our case, the diagnosis was already made as early as the late first trimester (figure 1) (online supplementary video 1).…”

We present a case of a 42-year-old woman with a pregnancy resulting from in vitro fertilisation and a medical history including two spontaneous abortions, hypercoagulable state and other comorbidities. At 13 4/7 weeks' gestation, during research ultrasonography, the patient was noted to have an anterior succenturiate placental lobe. Following an episode of vaginal bleeding at 21 6/7 weeks, she was diagnosed with a low-lying posterior placental lobe. Velamentous cord insertion, placenta previa and vasa previa were excluded at that time. After elective induction for advanced maternal age at 39 0/7 weeks, arrest of labour and chorioamnionitis resulted in a primary low transverse caesarean section and delivery of a healthy girl at 39 3/7 weeks. Gross examination of the placenta showed an irregular, singleton placenta with an attached succenturiate lobe and a marginally inserting umbilical cord. Both lobes were connected by two vessels.

“…14,15 Succenturiate lobes occur in 10% of placentas, and they are a risk factor for retained placental tissue and obstetric hemorrhage. [16][17][18] If a succenturiate lobe is not anticipated, what appears to be an intact placenta will lead to the false clinical assumption that the uterus is empty postpartum. On ultrasound, a succenturiate lobe appears a separate placental mass connected to the main placenta by intramembranous vessels (Figure 2).…”

“…18 When a succenturiate lobe is identified it should prompt evaluation for possible vasa previa. 16,18,[20][21][22][23][24][25][26][27][28]…”

Ultrasound assists in the diagnosis and management of obstetric hemorrhage. With improving technology and increasing availability, there has been a decreased morbidity and mortality from obstetric hemorrhage due to ectopic pregnancy, vasa previa and abnormal placentation. There is also theoretic benefit for the use of ultrasound in less common conditions such as uterine varix. The goal of this article is to review the common causes of obstetric hemorrhage; to review the ultrasound findings in these causes; and to discuss the intraoperative use of ultrasound in the treatment of obstetric hemorrhage. Objectives Review common causes of obstetric hemorrhage Review the ultrasound findings of these causes Discuss the role of ultrasound during procedures for obstetric hemorrhage
