OVARIAN VEIN EMBOLIZATION

What are the indications?

Ovarian veins embolization is a minimally invasive procedure used to block blood flow to the veins causing pelvic congestion and consequent pain.

Procedure

The procedure can be done on an outpatient or inpatient basis and is generally similar to general angiography and embolization and particularly to testicular vein embolization in males.

The radiologist will, with a help of X-rays, place the tiny tube (angiographic catheter) into the vein draining your ovaries and inject contrast to demonstrate the cluster of serpentine veins in your pelvis.

The preferred agents for embolization are coils or rarely sclerosing liquids. After administration, repeated injection of contrast will confirm that the ovarian veins are completely blocked.

The catheter will be removed and you will be monitored in the X-ray department for 2-3 hours for the possible complications.

Is there any additional risk?

The possibility that the coils can dislodge into the venous system and be flown into your lungs is minimal. Even if it happens, you will probably not notice it, as the lungs vasculature capacity is big enough to compensate. Sometimes we may need to use vascular foreign body retrieval system to catch the loose coil. You will be advised to avoid any heavy physical activity for the 5-7 days in order to prevent late dislodgement.

Sometimes, the anatomy of the ovarian veins and their branches may be too complex for the successful blockage. In that case the radiologist will advice you that the procedure is not technically feasible and your attending doctor will present you with the other treatment options.

Some patients complain of mild discomfort and pain in the pelvis over the next 24-48 hours after the procedure, which will necessitate administration of painkillers.

Pelvic pain is a very common symptom in women and it is sometimes difficult to select the patients that will benefit from embolization. As the multiple additive causes may be responsible for the symptoms, a team of physicians should be involved in order to produce desirable results.

The other risks are similar to general angiography and embolization
