What does "incomplete septate uterus" mean?

In general, an incomplete septate uterus refers to an abnormal uterine development characterized by the presence of a partial septum inside the uterus that incompletely divides the uterine cavity. This septum does not extend throughout the entire uterine cavity. Detailed analysis is as follows:

An incomplete septate uterus refers to the presence of partial longitudinal septal tissue within the uterus, which incompletely divides the uterine cavity into two sections. This condition results from incomplete fusion of the bilateral müllerian ducts during embryonic development. The septal tissue does not fully extend to the internal cervical os, and the lower part of the uterine cavity remains connected, clearly distinguishing it from a complete septate uterus. Clinical manifestations of an incomplete septate uterus vary significantly among individuals. Some individuals may remain asymptomatic throughout their lives, with the condition discovered only incidentally during physical examinations. Others may experience symptoms such as increased menstrual flow or dysmenorrhea.

Pregnant patients with an incomplete septate uterus require special attention to prenatal monitoring, as the septum may create uneven pressure within the uterine cavity, increasing the risk of complications such as premature rupture of membranes and placental abruption. It is also important to be vigilant for abnormal uterine bleeding or worsening dysmenorrhea in daily life, as these symptoms might indicate the presence of other concurrent gynecological conditions.
