Current literature describes a wide variation regarding regulation of placental cord insertion (PCI) documentation during antenatal ultrasound. Insertion of the umbilical cord within <2 cm from the placental margin is described as marginal cord insertion (usually defined as <2 cm 5, although some references define it as <1 cm 3,6 ). Abnormal placental cord insertion (PCI) includes marginal cord insertion (MCI) and velamentous cord insertion (VCI). Velamentous and marginal cord insertion may be difficult to differentiate as the vessels in a velamentous cord lacking Wharton's jelly are smaller and thinner than normal umbilical vessels making them more difficult to identify using gray-scale imaging alone (5). Antenatal ultrasound. DIFFERENTIAL DIAGNOSIS. The fetal blood vessels also travel unprotected from the placenta until they come together and reach the protection of the umbilical cord. VCI has been.

To evaluate whether various umbilical cord abnormalities, including velamentous, marginal cord insertion (VCI, MCI), hypercoiled cord (HCC) and nuchal cord (NC), affect the appearance of atypical. A velamentous umbilical cord is characterized by membranous umbilical vessels at the placental insertion site; the remainder of the cord is usually normal. A velamentous cord insertion may be detected as early as the first-trimester sc ipez n 4. 12 If the vessels from the velamentous cord insertion run across or near the cervix, this may become a vasa praevia. 5). Also, the diagnosis of Battledore placenta by ultrasound is possible and is better done in second trimester as localization of the site of cord insertion becomes difficult with increasing gestational age. vasa previa. The umbilical cord usually runs from the centre of the placenta to the fetus. A marginal placenta previa (or grade 2 placenta previa) is a form of placenta previa where placental tissue reaches the margin of the internal cervical os but does not cover it. In the above case, an associated nuchal cord was found. Marginal praevia Marginal placental previa Grade 2 placenta praevia Grade 2 placenta previa URL of Article A marginal placenta previa (or grade 2 placenta previa) is a form of placenta previa where placental tissue reaches the margin of the internal cervical os but does not cover it.
