A Study Of 56 Cases Of Torsion Of Umbilical Cord Abstract

Objective:To investigate the prenatal diagnosis, abnormal clinical manifestation, relative management, and the relationship between the method of delivery,the fetus status and torsion of cord.Methods:56 pregnant women with torsion of cord cases reported from June 2007 to February 2009 were analyzed retrospectively, compared with 60 cases pregnant women without torsion of cord at the same time. To analyzed the diagnostic value of prenatal examinations in detecting torsion of cord, include the abnormal fetal heart, the abnormal fetal movement, the Fetal heart rate( FHR) monitoring, the color Doppler ultrasonographic assessment. The method of delivery and the effect to the fetus prognosis was evaluated. And two group were no different in symptoms of complications.Results:1.The incidence of torsion of cord in this research was 7.865%.2.About 96.4% torsion of cord cases can be projected by com- bining prenatal color Doppler ultrasonographic assessment with the FHR monitoring. 3.None of the umbilical blood S/D in the two groups was reduced. 7 cases were ascensused in the study group which occured in approximately 12.5% of all cases in the study group. The umbilical blood S/D in study group was significantly higher than those in normal group.4. The incidence of fetal distress, neonatal asphyxia,feta growth restriction in study group were significantly higher than those in normal group .5.The torsion of cord also led to the decrease of natural labor and the increase of cesarean sreduced.6.The abnormal clinical manifestation cases in the group with torsion of cord were different in the length of the two consecutive umbilical coiling. The length was 2.170±0.108 cm.Conclusion: The application of prenatal color Doppler ultrasonographic assessment, the fetal heart monitoring, the umbilical blood S/D, et al, we could find fetus in anoxia status earlier, and give evidence to the time and method of delivery.
