A McDonald cerclage, described in 1957, is the most common, and is essentially a pursestring stitch used to cinch the cervix shut; the cervix stitching involves a band of suture at the upper part of the cervix while the lower part has already started to efface. [2] This cerclage is usually placed between 16 weeks and 18 weeks of pregnancy.
Cervical pessary is a medical device used to treat an incompetent (or insufficient) cervix (cervix starts to shorten and open too early). Early in the pregnancy a round silicone pessary is placed at the opening to the cervix to close it, and then it's removed later in the pregnancy when the risk of a preterm birth has passed.
Hydroxyprogesterone caproate 250 mg IM weekly preferably starting at 16–20 weeks until 36 weeks is recommended. In these women, if the transvaginal ultrasound cervical length shortens to <25 mm at < 24 weeks, cervical cerclage may be offered.
Cervical weakness can be treated using cervical cerclage, a surgical technique that reinforces the cervical muscle by placing sutures above the opening of the cervix to narrow the cervical canal. [8] Cerclage procedures usually entail closing the cervix through the vagina with the aid of a speculum. Another approach involves performing the ...
The routine use of a cervical collar is not recommended. [2] [3] [6] Cervical collars are also used therapeutically to help realign the spinal cord and relieve pain, [7] although they are usually not worn for long periods of time. [8] Another use of the cervical collar is for strains, sprains, or whiplash.
Dilation (or dilatation) and curettage (D&C) refers to the dilation (widening or opening) of the cervix and surgical removal of sections and/or layers of the lining of the uterus and or contents of the uterus such as an unwanted fetus (early abortion before 13 weeks), remains of a non-viable fetus, retained placenta after birth or abortion as well as any abnormal tissue which may be in the ...
Preterm cervical shortening is linked to preterm birth and can be detected by ultrasonography. Cervical cerclage is a surgical intervention that places a suture around the cervix to prevent its shortening and widening. Numerous studies have been performed to assess the value of cervical cerclage and the procedure appears helpful primarily for ...
It is unproven that cerclage procedures are helpful. Although it is unclear whether interventions before conception or early in pregnancy such as resection of the rudimentary horn and prophylactic cervical cerclage decidedly improve obstetrical outcomes, current practice suggests that such interventions may be helpful.
