Fetal blood vessels traveling between these lobes may end up positioned above the cervix, causing vasa previa. A succenturiate lobe is a variation in placental morphology and refers to a smaller accessory placental lobe that is separate to the main disc of the placenta. Placenta Abnormalities Article - StatPearls The estimated worldwide incidence of succenturiate placenta is 1.04% [7]. Risk factors associated with vasa previa are mid-trimester placenta previa (even if the placenta is not low lying in the third trimester) 3, 11, presence of succenturiate lobes 2, 3, velamentous cord insertion 2, 3, multiple pregnancy 3 and in-vitro fertilization (IVF) pregnancy 3. The 2022 edition of ICD-10-CM O43.19 became effective on October 1, 2021. succenturiate lobe is defined as being a distinct placental lobe separate from the main placental disc and having vascular connections which run through the membranes connecting the main placenta to the succenturiate lobe [5, 6].

Click card to see definition . Placenta Some of the most common placental abnormalities include structural anomalies (such as a succenturiate lobe or velamentous cord insertion), implantation anomalies (such as placenta accreta and placenta previa), and functional anomalies (such as placental insufficiency). Membranous vessels can also arise as aberrant branches of a marginally inserted umbilical cord or they can connect lobes of a bilobed placenta or the placenta and a succenturiate lobe. The above ultrasound and color Doppler images show the lower margin of the placenta partially covering the internal os, suggesting partial placenta previa. Im expecting a scan at32 weeks to see if it has moved. One or multiple accessory lobes connected to the main disc by blood vessels that are at risk for hemorrhage and thromboemboli.

We're just back from a private reaasurance scan at 25wks. Also called succenturiate lobe. Vasa previa occurs when fetal blood vessels, that are unprotected by the umbilical cord or placenta, run through the amniotic membranes and traverse the cervix. doc isnt saying much, except to get to the hospital if bleeding happens, bed rest etc. Velamentous cord insertion, placenta previa and vasa previa were excluded at that time. 2 2 Melcer Y, Maymon R, Jauniaux E.

Placenta previa is a potentially life-threatening condition for both mother and infant. It accounts for the most incidents of bleeding in the third trimester of pregnancy. Sonographer said she wasn’t concerned but would refer for a consultant apt which I have next week. Due to focal noninvolution of chorionic laevae. Vascular connections of fetal origin usually connect the main placental mass to the succenturiate lobe. This occurs normally in 1:2500-5000 pregnancies and leads to complications similar too those for Placenta Previa.Type II is defined as the condition where the fetal vessels are found crossing over the internal os connecting either a bilobed placenta or a succenturiate lobe with the main placental mass. Sometimes, placental tissues extend over the internal cervical os; this is called placenta previa. placentas, placen´tae ) ( L. ) an organ characteristic of true mammals during pregnancy, joining mother and offspring, providing endocrine secretion and selective exchange of soluble bloodborne substances through apposition of uterine and trophoblastic vascularized parts. 1. Abstract. The usual term placenta is about 22 cm in diameter and 2.0 to 2.5 cm thick. Vasa previa may result from vessels running in the membranes between the two lobes. Possibility of vasa previa increases in older woman who underwent in-vitro fertilization. Previa of a succenturiate placenta is a rare condition. Associated abnormalities: Vasa previa usually occurs in association with velamentous cord insertion, bipartite placenta, or succenturiate lobe, where vessels run through the membranes to join the separate lobes. We report two cases of such lesions, which could not be detected by transabdominal ultrasound. This case demonstrates ultrasound findings consistent with a succenturiate lobe of placenta (multilobed placenta), which confers an increased risk of vasa previa, placenta previa, antepartum hemorrhage, post partum hemorrhage and retained placenta (and therefore post partum infection). Placenta percreta is a form of placenta accreta in which the placental villi penetrates the myometrium to the uterine serosa. The succenturiate placenta is a condition in which one or more accessory lobes develop in the membranes apart from the main placental body to which vessels of fetal origin usually connect them. THERE does not appear to be a great deal written concerning placenta previa of a succenturiate lobe. All is fine, baby is still on the petite side (strange when I am 5'11 and OH is 6'5!)

These vessels may be from either a velamentous insertion of the umbilical cord or may be joining an accessory (succenturiate) placental lobe to the main disk of the placenta. A succenturiate lobe is a variation in placental morphology and refers to a smaller accessory placental lobe that is separate to the main disc of the placenta. As such, antenatal diagnosis is essential to adequately prepare for childbirth. The estimated worldwide incidence of succenturiate placenta is 1.04% [7]. The 2 main causes of vasa previa are velamentous insertions (where the cord inserts directly into the membranes, leaving unprotected vessels running to the placenta) (25–62%) and vessels crossing between lobes of the placenta such as in succenturiate or bilobate placentas (33–75%) 16).Less commonly, a vessel that … … At least 50 percent of vasa previa are due to accessory placenta.

Vasa previa is a rarely reported condition in which exposed fetal vessels traverse the amniotic membranes between the baby’s presenting part and the internal cervical os, unprotected by placental tissue or umbilical cord. There can be more than one succenturiate lobe. Our 20wk NHS scan was very rushed and the femur was measuring a bit short so we decided to have a check up scan this week. Vasa previa results from a succenturiate placenta when fetal vessels joining the two lobes of the placenta are located between the baby's presenting part and the cervix or if the cord insertion is located between the two lobes (velamentous insertion of a bilobed placenta)." The 2 main causes of vasa previa are velamentous insertions (where the cord inserts directly into the membranes, leaving unprotected vessels running to the placenta) (25–62%) and vessels crossing between lobes of the placenta such as in succenturiate or bilobate placentas (33–75%) (36, 56). In singleton pregnancies, abnormally shaped placentae such as circumvallate placenta and succenturiate lobes of placenta have been reported to be clinical important [1, 2, 7, 9–11].Circumvallate placenta is an abnormally shaped placenta demonstrating a marginal fold of the chorion and a projection of villous tissue beyond the edge of the chorion plate. Membranous vessels can also arise as aberrant branches of a marginally inserted umbilical cord or they can connect lobes of a bilobed placenta or the placenta and a succenturiate lobe. A succenturiate (accessory) lobe is a second or third placental lobe that is much smaller than the largest lobe. There are two types, depending on if the free vessel is connected to a velamentous cord (type I) or connected to a succenturiate or accessory lobe of the main placenta (type II).
