Are 3D ultrasound and office hysteroscopy useful for the assessment of uterine cavity after late foetal loss?

Abstract

ObjectiveTo assess the efficacy of office hysteroscopy and 3D ultrasound for the diagnostic of uterine anomalies after late foetal loss. MethodThis retrospective observational study took place in the gynaecologic unit of a teaching hospital from 2009 to 2014. Women with late foetal loss (<22 weeks of gestation) had an office hysteroscopy and 3D ultrasound within three months after delivery. The results of the ultrasound and hysteroscopy were recorded and compared. ResultsEighty women were included with a mean age of 29.8 years (28.2–31.4). Forty-seven women had both hysteroscopy and 3D ultrasound, and a uterine cavity's anomaly (bicornuate uterus, T-Shape uterus and septate uterus) was found in ten women (21%) at 3D sonography and in 13 women (28%) at office hysteroscopy. Concordance between the two exams was very good with a kappa at 0.83. In three cases, a uterine cavity's anomaly was found at hysteroscopy whereas sonography was normal. Anomalies at ultrasound (uterine cavity's anomaly, myometrium anomaly or ovarian anomaly) were found in 27.6% of cases. ConclusionsBoth 3D ultrasound and office hysteroscopy are useful for assessment of the uterine cavity after late foetal loss. The application of these two exams is important, as hysteroscopy is generally used for assessment of the uterine cavity and endometrium, while 3D ultrasound is generally used to identify the precise type of uterine malformation and for the examination of the myometrium and annexes.
