ABSTRACT We present a case of bilobed placenta diagnosed by HDliveFlow with the HDlive silhouette mode early in the 2nd trimester of pregnancy. A 29-year-old Japanese pregnant woman, gravida 4, para 1, was referred to our hospital based on the patient's wish at 23 weeks and 3 days of gestation. Two-dimensional (2D) sonography showed a single live fetus with biometry consistent with the gestational age. Moreover, two separated parts of the placenta were noted at the anterior and posterior uterine walls. HDliveFlow with the HDlive silhouette mode clearly depicted two lobes of the placenta (near equal size), and the main umbilical cord attached to the periphery of the anterior part of the placenta. One large connecting vessel between these two placental parts was also clearly identified. Bilobed placenta was strongly suggested. After birth, the gross specimen of the placenta confirmed the diagnosis. HDliveFlow with the HDlive silhouette mode may be an adjunctive tool to 2D sonography to diagnose abnormalities of the placenta in utero.

Abstract Background True umbilical cord knots are common incidental findings at birth, however, there are limited reports of antenatal diagnosis. True knots are mostly asymptomatic; however, cord related accidents may be encountered. Case presentation We present two cases we diagnosed and followed-up antenatally. We reviewed previous literature and found 16 reports of antenatal diagnosis. In addition to foregoing established risk factors, we noticed an increased risk at first trimester screening in our cases. Conclusions Modern ultrasonography (USG) technology applications are valuable for monitoring knot architecture and compression. We propose monitoring the baby with daily kick counts and biweekly cardiotocography after 28–30 weeks of gestation. Weekly umbilical Doppler pulsatility (PI) measurements of afferent and efferent loops with respect to the gestational age, aids in monitoring the tightness of the knot. The timing and route of delivery should be necessitated by obstetric indications. Vaginal delivery is possible under continuous fetal monitorization during labor.

Ultrasonographic Appearance

AbstractUmbilical cord teratomas are rare tumoral lesions of umbilical cord which have challenging antenatal diagnosis. The cord teratomas contain tissue from all three germ layers and have both cystic and solid components. This ultrasonographic appearance may help the clinician to clarify the correct diagnosis. We report a case of cord teratoma diagnosed prenatally by ultrasonography and magnetic resonance imaging. Since cord teratomas may lead to adverse fetal outcomes, close follow-up of the fetus is recommended.

AbstractObjectivesUmbilical artery thrombosis is a significant umbilical cord condition that is associated with adverse pregnancy outcomes. However, no consensus has been reached regarding how umbilical artery thrombosis should be diagnosed or managed because of its rarity and the difficulty associated with an antenatal diagnosis.Case presentationHere, we describe a case involving decreased fetal movement and non-reassuring fetal status (NRFS) in which acute umbilical artery thrombosis was prenatally diagnosed. Transabdominal ultrasound showed that the cross-section of the umbilical cord had one normal artery and a small deformed echogenic area. A characteristic ultrasound finding known as the “wink sign” contributed to the prenatal diagnosis.ConclusionsEvaluation of the umbilical cord enabled the estimation and facilitated the subsequent antenatal management.

Vestiges of the omphalomesenteric or vitello-intestinal duct and the pathologic implications attributed to these remnants have been treated in great detail by several investigators. Persistence of the omphalomesenteric duct is associated with such conditions as Meckel's diverticulum, umbilical fistula, mucosal polyps, and sinuses or cysts of the umbilicus. Remnants of the duct in the umbilical cord, although infrequent, are located outside of the triangle formed by the two umbilical arteries and the umbilical vein, are usually discontinuous and are often represented by a small lumen lined by cuboidal or columnar epithelium. This study will examine the ultrastructure of these cells.
