Cervical nuchal translucency is also known as cervical nuchal cyst. Cervical nuchal translucency is caused by chronic inflammation of the cervix, resulting in localized glandular duct obstruction and the formation of small greenish-white vesicles, which are often clinically asymptomatic and are only detected during gynecological examinations. It is recommended that women should pay attention to the hygiene of sexual life and menstrual hygiene in daily life to avoid cervical inflammation. It is also recommended to reduce the history of cervical operations, for example, it is better to take good contraceptive measures if no pregnancy is planned, and avoid abortion when pregnant, which may cause damage to the cervical mucosa and lead to the invasion of pathogenic bacteria and the formation of chronic cervical inflammation.
