[Indications and results of cerclage in cervical incompetence (author's transl)]

The results of 79 cerclage operations in gestation are reported. The rate of abortion increased in cases of more severe symptomatics: firstly, without labour and bleeding: 83 p.c. successful operations; secondly, with labour: 77 p.c.; thirdly, bleeding and without labour: 70p.c.; and lastly, with labour and bleeding: 40p.c. Before treatment with tocolytic pharmaca was possible, the period of gestation time could not successfully be prolonged if labour had started. With tocolytic pharmaca 56p.c. patients of this group gave birth to a living child. The rate of premature children was 23p.c. Cerclage operations were most successful after the 25th week of gestation. When applied before the 16th week of gestation, the success rate was below 69p.c. Treatment with tocolytic pharmaca increased the indication for cerclage operations. Cerclage operations together with tocolytic treatment are indicated in cases where labour and bleeding occur in gestation.
