The complete septate uterus with cervical duplication and vaginal septum

Septation of the uterus occurs as a result of incomplete absorption of the fused area of the two Müllerian ducts, this may lead to a complete or partial septum formation. The complete septum reaches the os, completely dividing the uterus into two cavities. The partial septum or sub-septum divides the uterus partially sparing the os. Complete septated uteri are classified as class Va and partially septated uteri are class Vb.
