**5.4. Succenturiate placenta**

In succenturiate placenta a smaller accessory placental lobe develops in the membranes, apart from the main disc of the placenta. There can be more than one succenturiate lobe, and it is a smaller variant of a bilobed placenta. In placenta supuria the communicating membranes do not have vessels [1]. As risk factors, advanced maternal age, in vitro fertilization, primiparity, proteinuria in the first trimester of pregnancy, and implantation over leiomyomas or in areas of previous surgery have been cited in the literature [1]. This condition can be diagnosed in 5% of pregnancies, by ultrasound scan as a smaller separate lobe similar to the main placental lobe. Caution should be considered in identifying any connecting vessels, especially vasa praevia. Differential diagnosis may also include focal myometrial contraction and iso-echoic hematoma from a placental abruption. Complications may appear as there is an increased risk of vasa praevia and postpartum hemorrhage, due to retained placental tissue.
