Analysis of the relationship between venous reflux and fallopian tubal patency in hysterosalpingo contrast sonography and its influencing factors
Objective To analyze the correlation between the venous reflux and the fallopian tube patency in hysterosalpingo contrast sonography(HyCoSy).Methods A total of 80 infertile patients who were examined by HyCoSy in Taicang Hospital of Traditional Chinese Medicine from January 2021 to June 2022 were selected as study objects.The patients were divided into reflux group(n=31)and non-reflux group(n=49)according to whether there was contrast medium venous reflux.The fallopian tubes patency in the two groups was compared.The independent influencing factors of patients with contrast medium venous reflux were analyzed by multivariable Logistic analysis,and the nomogram prediction model was constructed based on independent factors,and the model was verified.X-tile software was used to determine the cut-off value of the prediction model and establish survival curve.Results The proportion of bilateral tubal patency type(A+A)patients in the reflux group was significantly lower than that in the non-reflux group(P＜0.05),and the proportions of type(B+C)and(C+C)patients were significantly higher than those in the non-reflux group(P＜0.05).Endometrial thickness＜5.45 mm,bilateral tubal patency type(B+C)and(C+C)were independent risk factors for contrast medium venous reflux(P＜0.05),and bilateral tubal patency type(A+A)was protective factor(P＜0.05).The nomogram prediction model constructed by independent influencing factors has good discrimination and accuracy.Risk stratification and survival curves suggest the risk of contrast medium venous reflux increased with the total score increasing.Conclusions Patients with more severe obstruction of the fallopian tubes had a higher risk of contrast medium venous reflux.HyCoSy examination can effectively reduce the incidence of contrast medium reflux when the endometrial thickness is≥5.45 mm.
