There are two main reasons that you may be asked to have an ovarian vein ultrasound scan. The first could be because of the site of the varicose veins in your legs, particularly if the veins occur in your thighs and groin. The second is because you may have symptoms that can indicate pelvic congestion syndrome, such as dull aching and dragging pains in the pelvis.
Just like the veins in your legs, it’s possible for the valves in the ovarian vein to stop working adequately and as a result the flow of blood drains into the pelvic region and then into the leg.
As well as evaluating the flow in the ovarian veins, the sonographer will examine other deep veins in your abdomen. This is to assess for blood clot in the vein, any blood flow in the wrong direction as a result of the valves no longer functioning or to see if there is any compression of any of the veins.
The primary purpose of this ultrasound scan is to check to see which way the blood is moving in the ovarian veins. Typically, patients will have two ovaries, one on the right and one on the left. Each of them will have at least one vein taking flow away from the ovary back towards the heart. The sonographer will check to see if the flow is travelling in the correct direction or if it is flowing back into your ovary.
Other causes of pelvic symptoms can be related to the anatomy, and variations in your anatomy can result in some of the veins being compressed which in turn can affect the flow of blood.
There are two main types of compression that the sonographer will look for:
In the vascular laboratory this is an external scan and there is no need to remove underwear.
To perform the scan, you will just need to lift your shirt and lower your pants/underwear onto your hips. The sonographer will use gel and transducer on your abdomen, they will often have to press firmly to image the veins. Once the scan is completed the report will be done so that Dr Theivendran can consider the best approach to dealing with your symptoms. Typically, this ultrasound scan will take approximately 15-30 minutes.
