OBJECTIVES: To explore the risk factors on contrast agent venous intravasation during transvaginal 4-dimensional hysterosalpingo-contrast sonography (TVS 4D-HyCoSy). METHODS: The TVS 4D-HyCoSy imaging data were collected from 276 female infertile patients. The correlation between endometrial thickness, days after menstruation, intrauterine intervention history, fallopian tubal patency degree, and contrast agent venous intravasation, respectively, was analyzed. RESULTS: In our study, the incidence of contrast agent venous intravasation was 13.04%. Endometrial thickness and days after menstruation were significantly associated with venous intravasation (P < .05). However, there was no significance for intrauterine intervention history and fallopian tube patency degree. CONCLUSIONS: Contrast agent intravasation during TVS 4D-HyCoSy is not infrequent. Performing TVS 4D-HyCoSy according to endometrial thickness and menstrual period could reduce intravasation incidence to some extent.
