What are the dangers of having a uterine septate uterus?

There are many manifestations of abnormal uterine development in women, including uterine septate. Uterine septate can cause many uncomfortable symptoms in patients, such as heavy menstrual flow, which is usually accompanied by dysmenorrhea. Female patients of this type are prone to infertility, and even if they become pregnant, they are prone to miscarriage. It can be seen that the harm of abnormal uterine development and uterine septate is relatively large.

Uterine dysplasia and septate uterus hazards:

1. Uterine septum and pregnancy are actually often due to the influence of the septum, the uterine cavity is deformed, leading to an increased incidence of late pregnancy complications, such as premature birth rate of 11%~28%. After corrective surgery, the premature birth rate can be reduced to 6%~9%. Uterine malformation can also lead to obstetric complications such as abnormal fetal position, uterine contraction dysfunction, and retained placenta.

2. Ectopic pregnancy (also known as ectopic pregnancy) Due to the complexity of uterine malformations, ectopic pregnancy (also known as ectopic pregnancy) can often occur in closed uterine horns, rudimentary uterine horns, cervix or vaginal diverticula. Because of their rarity, pregnancies in this unusual location are often difficult to diagnose early.

3. The incidence of uterine septate and pregnancy is 17%~35%, and the pregnancy rate after uterine septate correction surgery is 48%. Some scholars also believe that uterine septate is not a factor leading to infertility, but in patients with secondary infertility, the incidence of unexplained infertility increases significantly to 40%. Therefore, it cannot be ruled out that uterine septate is one of the factors affecting conception in this type of patients.

Diagnostic ideas

In clinical practice, the diagnosis of uterine malformations should be given priority, especially when a gynecological examination reveals that the cervix is ​​extremely asymmetrical in the vaginal vault, the cervix is ​​particularly large and has a septate, the possibility of a uterine septate should be considered. Those with vaginal septate, infertility after marriage, repeated spontaneous abortions, missed abortions, or continued pregnancy should be highly alert to the presence of a septate uterus and conduct further examinations to rule it out.

Differential Diagnosis

A completely septate uterus should be differentiated from a didelphys uterus, and an incompletely septate uterus should be differentiated from a bicornuate uterus. The ultrasonic imaging characteristics of a bicornuate uterus are that the cross-section of the uterine body and cervix is ​​relatively wide, but two horn-shaped uterine horns can be seen in the cross-section of the uterine fundus, and lobed uterine cavity waves can be seen in the two horns. If differentiation is difficult, laparotomy can be performed if necessary.

Diagnostic criteria

The diagnosis is based on clinical confirmation that there is only one uterus.

1. Complete mediastinum: The uterine septum extends from the fundus of the uterus to the internal os of the cervix.

2. Incomplete septum: The uterine septum extends from the fundus of the uterus but does not reach the level of the internal cervical os, and only separates the cervix.
