[Anamnesis and course of gestation associated with surgical closure of the cervix (author's transl)].

During a time interval of 2 years in 7% of the gravidae at the First Department of Obstetrics and Gynecology, University of Vienna, a surgical closure of the cervix was performed. The anamnestic and clinical data of these 221 gravidae were compared with a compatible collective of another 221 gravidae without a surgical closure (control-group). In the closuregroup 27,6% were primigravidae. The mean age of the gravidae was 28,8 years and statistically higher than in the control group (25,7 years). Also the mean age of the multigravidae at the time of their first gestation was statistically higher (23,9 years and 22 years respectively). The anamnestic amount of abortion and perinatal mortality was 63,5% and 24,3% respectively, significantly higher was also the anamnestic rate of curettages. In most of the cases surgical closure was indicated by palpation of the cervix, 3 degrees of insufficiency of the cervix were differentiated. There was a great importance of a postsurgical treatment with tocolytic drugs (83% and 10% respectively), but there was also a different mode of application. During the course of gestation a lower frequency of EPH-gestosis (64 gravidae and 90 gravidae respectively) but a higher incidence of diabetes (11 gravidae and 5 gravidae respectively) and a higher incidence of urinary infection (20 gravidae and 7 gravidae respectively) were observed. In patients with a cervical closure a higher rate of rupture of membranes and premature labor were present. Surgical technique and time of closure had no significant influence on the outcome of pregnancy. The rate of success was 86.4%.
