Study of Risk Factors and Early Diagnosis of Adnexal Torsion / 医学研究杂志

ABSTRACT

Objective To analysis the risk factors,clinical manifestations of adnexal torsion(AT) during pregnancy,providing evidence for the early diagnosis of AT in pregnancy.Methods Retrospective data were collected from 40 women who underwent surgery for AT during pregnancy between May 2006 and August 2016 at the first affiliated hospital of Wenzhou Medical University.In addition,94 women diagnosed with non-torsion adnexal during pregnancy were chosen to serve as control subjects.The risk factors and clinical characteristics of the two groups wcre compared.Results AT during pregnancy were likely to occurring within the 6th and 14th week of gestation.The rate of the adnexal masses with sizes between 5 and 8cm was significantly higher in torsion group(P ＜ 0.05).The rate of ovarian hyperstimulation syndrome (OHSS) was shown to be obviously elevated in the torsion group (P ＜ 0.05).The white blood cell counts,neutrophil ratio,the rate of lacking of intra-adnexal blood flow on color Doppler imaging were significantly elevated in torsion group (P ＜0.05).Conclusion The risk factors of AT during pregnancy may be occured within the 6th and 14th week of gestation,cyst sizes between 5 and 8cm and combined with OHSS.Adnexal tumors bearing higher risks for torsion and should be strongly considered for an aggressive strategy of management during pregnancy.Moreover,the combined detection of the white blood cell counts and neutrophil ratio as well as doppler imaging can contribute to the early diagnosis of AT during pregnancy.
