Abstrakt		Background: With transvaginal sonographic cervical evaluation we attempted to objectify anatomic changes of the cervix in pregnant women with clinical suspicion of incompetence in the second trimester of pregnancy. Methods: In a group of 112 singleton-pregnant women with clinical suspicion of incompetent cervix or with a history of premature birth in previous pregnancies, US evaluation of cervical length and of the shape of the internal cervical os was performed. On the basis of repeated hospital gynecological examinations, the patients were divided in two groups: a study group of 57 women with cervical incompetence and a control group of 55 women with competent cervix. In all cases cervical evaluation was performed by transvaginal sonographic measurement of cervical length and of eventual changes of the internal cervical os. Results: In 57 of 112 women clinical evaluation of the cervix revealed a length of 1 cm or less. In this clinically suspicious group, the measured cervical length was between 11 mm and 52 mm, the calculated mean cervical length was 29.2 mm and standard deviation 8.59. Dilatation of the internal cervical os exceeding 5 mm was found in 22 of 57 cases. In the control group of 55 women, the measured cervical length was between 21 mm and 50 mm, the calculated mean cervical length was 36.5 mm and standard deviation 6.87. Dilatation of the internal cervical os exceeding 5 mm was found in 5 cases. Conclusion: !n more than half of the cases in our study group, cervical length values were unexpectedly high for an incompetent cervix. This was also reflected by the low percentage of (at least minimal) changes of the internal cervical os shape, which was found in 39% (22/57).
