Uterine cervical incompetence is the most common cause of habitual abortion in the second trimester of pregnancy and premature delivery; cervical cerclage still represents the only surgical treatment for cervical incompetence. In the last 20 years (1971-1990) we performed 272 Mac Donald cervical cerclages in patients between the 8th and the 34th week of pregnancy. In 16 cases the outcome of pregnancy is unknown; 198 women (73.3%) subsequentely delivered healthy infants later than 37 weeks' gestation or weighing more than 2500 g.
子宫颈机能不全是妊娠中期习惯性流产和早产的最常见原因；宫颈环扎术仍是治疗子宫颈机能不全的唯一外科手术方法。在过去20年（1971 - 1990年）中，我们对妊娠8至34周的患者进行了272例麦克唐纳宫颈环扎术。16例患者的妊娠结局未知；198名妇女（73.3%）随后分娩出健康婴儿，孕周超过37周或体重超过2500克。
