Vasa previa is seen more commonly with velamentous insertion of the umbilical cord, accessory placental lobes (succenturiate or bilobate placenta ), multiple gestation, and in vitro fertilisation pregnancy. In IVF pregnancies, incidence as high as one in 300 has been reported [citation needed].
If such vessels are identified, vasa previa may be present and cervical length is measured every week to determine the risk of premature rupture of membranes. [ 16 ] Women diagnosed with velamentous cord insertion may also receive counselling about the condition, its risks, and potential courses of action, including preterm delivery or ...
Multilobed or Succenturiate Placenta When a placenta has multiple lobes which are distal and not of equal size this is referred to as a succenturiate placenta. Distal lobes are connected by a placental artery and vein extending from the main placenta, which tends to be centrally located and is the largest in mass. [ 20 ]
If there is a clearly discernible main lobe and auxiliary lobe, the latter is called a succenturiate placenta. Sometimes the blood vessels connecting the lobes get in the way of fetal presentation during labor , which is called vasa previa .
Placenta praevia or vasa praevia refers to the placenta or fetal blood vessels, respectively, covering or being located close to the opening of the uterus. More than half of women affected by placenta praevia (51.6)% have bleeding before delivery. [12] Vasa praevia occurs in about 0.6 per 1000 pregnancies. [13]
