Objective To observe the value of transvaginal two-dimensional ultrasonography(2D-TVS)combined with three-dimensional ultrasonography OmniView for diagnosing intrauterine adhesion(IUA).Methods Totally 200 women with suspected IUA were retrospectively enrolled,including 172 cases who were ultimately diagnosed IUA and the rest 28 without IUA.The efficacy of 2D-TVS combined with OmniView for diagnosing IUA was analyzed.Results Among 200 cases,150 cases were diagnosed IUA with 2D-TVS(135 cases were diagnosed correctly),167 cases were diagnosed IUA with OmniView(159 cases were diagnosed correctly),and 170 cases were diagnosed with combination of the above two(165 cases were diagnosed correctly).The area under the curve(AUC)of 2D-TVS,OmniView and 2D-TVS combined with OmniView for diagnosing IUA was 0.625,0.819 and 0.890,respectively,and 2D-TVS combined with OmniView had the highest AUC(both P＜0.05),with sensitivity of 95.93％,specificity of 82.14％,positive predictive value of 97.06％and negative predictive value of 76.67％.Conclusion 2D-TVS combined with OmniView could be helpful for diagnosing IUA.

[Summary] Hypercalcemia in pregnancy is a rare condition which brings considerable risks to mother and fetus. The most common cause is primary hyperparathyroidism(PHPT). The untypical symptoms and biochemical tests results add obstacles in the diagnosis of PHPT during pregnancy. The management is difficult, due to restrictions in choices of treatments and lack of clinical guidelines. Severity evaluation which takes consideration of calcium homeostasis during pregnancy is crucial for appropriate management. Parathyroidectomy during the second trimester is recommended for those with high serum calcium levels.
