To compare cervical catheter test and virtual hysterosalpingography (VHSG) in the evaluation of cervix before embryo transfer.

We evaluated 100 patients with history of infertility. The day of examination, a gynaecologist performed a cervical test with a Wallace catheter. Then, patients underwent VHSG performed with a 256-slice CT scanner. CT images were evaluated by a radiologist, and the cervical patency, utero-cervical angle and the presence of cervical pathology were determined.

There was a good correlation (r=0,92) in cervical patency evaluation between both methods. Unsuccessful cervical catheter test was observed in 35% of patients. In these patients, Virtual HSG detected polyps, adhesions and sinuous cervical canal, while cervix was normal in 23 patients, but the utero-cervical angle was < 90°. 

Virtual HSG findings correlate with cervical catheter test in the evaluation of cervical patency. Moreover virtual HSG provides anatomic information useful to identify the probable cause of failure of embryo transfers and prevent them.

Virtual HSG allows a complete description of the cervical canal, providing important prognostic information to the gynecologist prior to the completion of embryo transfer.
