Methods and materials

A prospective study was performed with 50 consenting women, referred for an ultrasound exam, with a history of recurrent first trimester pregnancy loss and / or primary infertility. Each patient was subjected to a 2D and 3D ultrasound, performed on a GE Voluson E8. Diagnostic hysteroscopy was performed following the ultrasound.

Data was analyzed and all the findings were clubbed in tabular pattern for the outcome of the result. 

Partial septate uterus (class U2a) characterized by the existence of a septum dividing partly the uterine cavity above the level of the internal cervical os [Fig. 4]. Complete septate uterus (class u2a) characterized by the existence of a septum fully dividing the uterine cavity up to the level of the internal cervical os [Fig. 5]. Patients with complete septate uterus (Class U2b) could have or not cervical (e.g. bicervical septate uterus) and/or vaginal defects [7]. Perform linear measurement from the tip to tip of the endometrial cavities (red line), which connects the two horns. Measure the longitudinal separation between above mentioned linear measurement and the fundus. If this crosses the fundus or is < 5 mm, the uterus is considered bicornis, while if it is > 5 mm is considered septate. Measuring the angle compound between both endometrial cavities, ideally performed on 3D ultrasonography in luteal phase. Considerations regarding the angle between the two endometrial cavities: If less than 75° is considered septate uterus. If it is 75° to 105° the differential diagnosis must be completed by adding hysteroscopy. Most are septate uterus. If the divergence angle is greater than 105° is a bicornuate uterus [Fig. 7] [8].
