Q51.3 | Bicornuate uterus |
ICD-10 online (WHO version 2019) |
The uterus bicornis , from Latin bi 'two' or 'double' and cornu 'horn', is a relatively common malformation of the uterus with division of the corpus (uterine body), but a common portio .
Classification
Depending on the extent of the subdivision, the following subdivision is common:
- Partial bicornuate uterus , only partial separation of the corpus
- Uterus bicornis unicollis , complete separation with common uterine neck (more common form).
As a transition form to the uterus didelphys there is the uterus bicornis bicollis , complete separation also of the portio.
Occurrence
The incidence is estimated at 0.1–0.5%.
root cause
It is based on a disorder in embryonic development in which the two Müller ducts only incompletely fuse, so that the uterus does not look normally pear-shaped, but rather "horned".
Clinical manifestations
There is a higher risk of premature birth and miscarriage , including uterine ruptures .
diagnosis
The diagnosis is usually made by sonography .
Differential diagnosis
Other uterine malformations such as uterus didelphys and uterus septus must be distinguished .
