Introduction
The preterm labor is a common pathology in obstetrics. Note that 9 % of births are premature (2010). The problems of prematurity are the importance of a reliable diagnosis. Endo vaginal ultrasound measurement of cervical length is a way more employees for this purpose.
Objective
Compare the diagnostic and prognostic accuracy of the vaginal ultrasound measurement of cervical length. Specify the positive predictive value of spontaneous preterm birth
Methods
They are 100 cases of MAP with intact membranes seen in the hospital Mahmoud El Matri. Terms of pregnancy vary between 28SA and 36SA 6 days.
Results
The average age of patients was 28.74 years, mean parity was 1.79.
The medium-term pregnancy is 33WA 4 days with extremes in 28WA and 36WA.
On admission the vaginal examination showed a greater than 1 finger dilatation in 69 % of cases with a deletion greater than 50% in 40 % of cases.
Cervical length is in 41% of patients lower or equal to 25 mm and in 59 % of patients it is less than 25mm. The average length of the neck is 26.85mm. For an equal length of neck 25mm negative predictive value is equal to 86.27 with good specificity to 68.75. For cervical length 20mm we have a weak VPN. For cervical length 30mm we have a low specificity. Of the 100 women admitted for MAP 28 and 72 gave birth prematurely to an end
Conclusion
The measurement of the cervix by trans-vaginal ultrasound is a part of everyday obstetric practice. Objectivity and low inter-operator variability allowed such additional examination to become an extension of the clinical examination
