Cervical cerclage: twenty years' experience. 1979

W A Peters, and S Thiagarajah, and G M Harbert

During a 20-year period, 40 pregnancies were managed in 32 patients with a diagnosis of an incompetent cervix, a ratio of 1:775 deliveries. Diagnosis before development of symptoms produced a 92% fetal salvage, with 68% reaching 36 weeks of gestation. Development of symptoms before cerclage resulted in only a 40% fetal salvage. Fetal salvage was reduced in cases where membranes bulged beyond the cervix, the cervix was more than 3 cm dilated, or the gestational age was greater than 26 weeks at the time of suture placement. No difference was noted between the Shirodkar and McDonald procedures. Major complications included uterine rupture in three patients and acute chorioamnionitis in two. Because of complications, treatment is contraindicated based on history alone or where close follow-up is not available.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D002581	Uterine Cervical Incompetence	Incompetent UTERINE CERVIX is usually diagnosed in the second trimester of PREGNANCY. It is characterized by passive painless cervical dilation in the absence of UTERINE CONTRACTION; BLEEDING; INFECTION; and sometimes with the amniotic sac (AMNIOTIC MEMBRANE) bulging through the partially dilated cervix. Left untreated, this condition may lead to premature pregnancy loss, such as HABITUAL ABORTION.

D002823	Chorion	The outermost extra-embryonic membrane surrounding the developing embryo. In REPTILES and BIRDS, it adheres to the shell and allows exchange of gases between the egg and its environment. In MAMMALS, the chorion evolves into the fetal contribution of the PLACENTA.	Chorions
