What is a Bicornuate Uterus?

During the development of the embryo, the tail ends of the paramedullary canals on both sides have mostly merged, and the terminal septum has been absorbed, so a cervix and a vagina are formed, but the part of the uterine base is not fully confluent, resulting in one corner protruding on each side , Called the double-horned uterus. Patients with bicornuate uterus may often have excessive menstrual flow and prolonged menstruation, and abortion, premature birth or abnormal fetal position may occur after pregnancy.

Common locations

uterus

Common causes

During the embryonic development, the paramedullary canals on both sides are affected and disturbed by certain factors during the evolution process

Common symptoms

Abnormal menstruation, abortion, premature birth or abnormal fetal position, etc.

Causes of Double Horned Uterus

The main cause is the embryonic development stage. During the evolution of the bilateral mesangial ducts on the two sides, it is affected and disturbed by certain factors. It can stop development at different stages of evolution and form various uterine abnormalities, including bicornuated uterus. .

Clinical manifestations of bicornuate uterus

Some patients with uterine malformations may not have any conscious symptoms, menstruation, sexual life, pregnancy, childbirth, etc., have no abnormal manifestations, so that they are not detected for life, or occasionally during physical examination. However, some patients' reproductive system functions are affected to varying degrees. At sexual maturity, after marriage, during pregnancy, or during delivery, the following symptoms may appear:

Abnormal menstruation

Patients with bicornuate uterus may often have excessive menstrual flow and prolonged menstruation.

2. Post-pregnancy performance

Uterine pregnancy, abortion, premature birth, or abnormal fetal position can occur.

3. Postpartum and postnatal performance

Malformed uterus often coexists with myometrial dysplasia. During childbirth, dystocia may occur due to abnormal fertility, difficulty in dilating the cervix, and even uterine rupture. Vaginal delivery can occur with placental retention, postpartum hemorrhage, or postpartum infection. In patients with bicornuate uterus, bleeding may occur due to discharge of decidua from the non-pregnant lateral uterine horn.

Double horn uterine examination

Ask for detailed medical history and gynaecological examination. Uterine fallopian tube angiography, pelvic color Doppler ultrasound, and hysteroscopy can confirm the diagnosis. Genital malformations are often associated with urinary system malformations or lower digestive tract malformations. Venous pyelography or barium enema can be performed if necessary. When abnormalities of the urinary tract or lower digestive tract are found, it is also necessary to check for genital malformations including uterine malformations.

Double Horn Uterine Diagnosis

Diagnosis can be confirmed based on clinical manifestations and related examinations.

Double Horn Uterus Treatment

Generally not treated. When repeated abortions occur, chromosome, corpus luteum function, and immune factors should be excluded. Hysteroscopic surgery can be performed and combined with laparoscopic surgery for treatment.
