Abnormalities in the Fallopian tubes (generally obstructions) can make the encounter between the ovum and the spermatozoon, as well as embryo implantation, difficult or even impossible.
The are several available techniques for analysing the condition of a woman’s Fallopian tubes. The ones that are most commonly used are hysterosalpinographies and sonohysterographies.
What is a hysterosalpinography (HSG)?
Hysterosalpinographies (HSGs) are the tests that have traditionally been used to study the Fallopian tubes and the uterus. The technique involves use of an X-ray and a contrast liquid containing iodine.
At Instituto Bernabeu, we have progressed from hysterosalpinographies to new, non-invasive and painless techniques that, furthermore, provide a more reliable diagnosis.
What is a sonohysterography?
A sonohysterogrpahy is a newer technique that allows us to assess the Fallopian tubes without having to use ionising radiation and contrast liquids. It involves high-resolution ultrasound imaging and a saline solution.
The procedure is performed in our clinic, ideally during the first part of the patient’s cycle. It allows us to assess the Fallopian tubes and other structures in real time, enabling us to determine if they are normal or if there are pathologies of any kind.
There is also another variation on the technique called a hysterosonosalpingography combined with a contrast liquid (HyCoSy). It facilitates a more precise diagnosis thanks to the hyperechoic contrast liquid that is used. The liquid consist mainly of water and is not embryotoxic. We have extensive experience with this technique at our clinic and obtain very satisfactory results. In addition to traditional ultrasound scans in 2D, we also use a 3D ultrasound scan and Doppler mode for improved diagnostic capacity.
Clinical guidelines recommend use of this method as the first option since it is very reliable, well-tolerated by patients and the associated level risk is <1%.
