UTERINE MALFORMATIONS

Classification

Since it is a video hysteroscopy literature, we will highlight only the malformations, and that this method contributes to propaedeutic diagnosis and procedure.

Septate uterus

It probably occurs by the lack of resorption on the middle line, in the merge of Müllerian ducts. The uterus is divided by a partial or total septum which is viewed as a crossbar, not covered by endometrium, which not bleeds when sectioned.
Complete septum when it occupies the whole extension of the cavity, dividing it into two hemicavities.
When this septum occupies only a part of the extension of the uterine cavity, it is considered as incomplete.

Unicornuate uterus

It presents a tubular cavity with an impaired intracavitary space, resembling the shape of a banana, whose the narrowest edge contains the tubal ostium. The endometrium is compatible with the menstrual cycle and the cervical canal is normal, in structure and trophism.

Bicornuate uterus

Malformation in which there is the lack of the flat portion of uterine fundus due to the lack of fusion on the proximal portion of paramesonephric ducts. The uterine fundus has two narrowed spaces in a divergent oblique angulation. It may be complete, from the fundus to the cervix; or partial, completely dividing the uterine cavity.
The tilted uterus which presents the most difficult hysteroscopic diagnosis occurs when there is only a small indentation of the uterine fundus.

Uterus didelphys

The presence of two uterine cervices and a double vagina, similar to unicornuate uteri, with a normal covering of endometrium.
