The aim of the present study was to describe the morphology of the cervix in Santa Ines ewes. One hundred cervices were collected from females of different ages (12 to 48 months). Five types of cervical os were observed: duck-bill, flap, rosette, papilla and spiral, with duck-bill being the most predominant type (51%) overall. The average cervix length was 4.68 cm (range of 3 to 7 cm). Shorter ...

OBJECTIVE To determine the normal range of uterine cervix within 4-24 weeks of pregnancy and also assess whether variations are related to some selected extraneous human conditions. SETTING AND DESIGN This was a prospective study conducted in University of Benin Teaching Hospital, Benin, Nigeria, and Nigerian National Petroleum Cooperation Health Centre, Warri, Nigeria. MATERIALS AND METHOD...

OBJECTIVE To examine the possible benefit of cervical cerclage in women with a very short cervix identified during routine sonographic assessment of cervical length at 23 weeks of gestation. METHODS Transvaginal sonography was used to measure cervical length at 23 weeks of gestation in 2702 women with singleton pregnancies attending for routine antenatal care. In 43 (1.6%) cases the cervical ...

Objective. The aim of this study was to assess whether cervical length measurement (CL) could predict preterm birth (PTB) in symptomatic women with a twin pregnancy. Methods. We searched MEDLINE and EMBASE to identify studies investigating the accuracy of CL measurement in predicting PTB in symptomatic women with a twin pregnancy. We extracted data to construct two-by-two tables and used bivari...

PURPOSE To analyze the feasibility of unilateral and bilateral translaminar screw placement in Koran population, and compare the acceptance rate using previously reported data in American population. MATERIALS AND METHODS The translaminar lengths, thickness, heights, and sagittal-diagonal measurements were performed. The feasibility analysis was performed using unilateral and bilateral 3.5 mm...

Objective Cervical length is often measured during the third trimester, especially in cases of threatened preterm labour. The gold standard is the transvaginal (TV) approach. A transabdominal approach is an alternative but it is often difficult to achieve a satisfactory image of the cervix in the third trimester. Transperineal (TP) ultrasound is considered less invasive and could offer a reliab...

BACKGROUND A thyroidectomy can be performed via a cervical incision in most patients with retrosternal goiter. AIMS To investigate the correlation between the volume of the mediastinal portion of the thyroid gland and the need for an extra-cervical approach for retrosternal goiter. STUDY DESIGN Diagnostic accuracy study. METHODS The measurement of craniocaudal length and the volume of the...

The cervical length is an important factor in the risk evaluation of preterm delivery. The aim of this work was to determine the correlation between the cervical length and the demographic characteristics. A transversal type prospective study was done on a sample of 579 pregnant women at various gestational age of low risk mono-fetal pregnancy. The cervical length was measured by trans-vaginal ...
