purse-string operation
Học thuậtThân thiện
Definition
Noun: 1. A specific surgical procedure to prevent preterm birth: A "purse-string operation" is a surgical intervention in which a suture (stitch) is placed around and through the cervix to close it. This procedure is performed during pregnancy when the cervix is incompetent—meaning it has weakened and begun to dilate too early, having failed to retain previous pregnancies, which poses a high risk of miscarriage or premature delivery. The stitch acts like a drawstring on a purse, holding the cervix closed until it is removed near the end of the pregnancy.
Usage Examples
- Noun:

- The success rate of the purse-string operation in preventing preterm birth is quite high for women with cervical insufficiency.
