The effect of cervical cerclage on the course of labor

Obstet Gynecol. 1990 Aug;76(2):168-71.


Although it is generally believed that patients with previous cervical cerclage have abnormal labor patterns, there is little evidence to support this belief. We analyzed the pattern of cervical dilatation during labor in 114 women with cervical cerclage by the McDonald procedure who delivered vaginally at term and compared them with 150 normal laboring women. Similar patterns of cervical dilatation were found in both groups and there was no case of cervical dystocia, a commonly cited complication of cervical cerclage.
