A cervical pregnancy is an ectopic pregnancy that has implanted in the uterine endocervix. [2] Such a pregnancy typically aborts within the first trimester , however, if it is implanted closer to the uterine cavity – a so-called cervico-isthmic pregnancy – it may continue longer. [ 3 ]
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.
Cerclages are usually performed between weeks 12 to 14 of the pregnancy. [8] The sutures are removed between weeks 36 and 38 to avoid problems during labor. The complications described in the literature have been rare: hemorrhage from damage to the veins at the time of the procedure; and fetal death due to uterine vessels occlusion.
Fetus at 14 weeks (profile) Obstetric sonography is useful in the assessment of the cervix in women at risk for premature birth. A short cervix preterm is associated with a higher risk for premature delivery: At 24 weeks' gestation, a cervix length of less than 25 mm defines a risk group for spontaneous preterm birth.
Up to the 13th week of pregnancy, the risk of miscarriage each week was around 2%, dropping to 1% in week 14 and reducing slowly between 14 and 20 weeks. [157] The precise rate is not known because a large number of miscarriages occur before pregnancies become established and before the woman is aware she is pregnant. [157]
