How pelvic vein embolisation is performed
Pelvic vein embolisation (or embolization) is performed in a radiology suite by a doctor who is trained to do this.
Under sterile conditions, the patient is usually given a light sedation. Using an ultrasound scan, a needle is put into a major vein, usually the jugular vein in the neck. Other doctors may prefer to try to use a vein in the groin, but this ends up with the equipment pointing the wrong way inside the major veins and is much harder to turn the catheter into the ovarian or internal iliac veins.
A very fine and very long tube called a catheter is inserted into the target vein using a guide wire under x-ray control, whether it is an ovarian vein or internal iliac vein. The doctor uses the results from the transvaginal duplex ultrasound scan to decide which veins to treat. Venous incompetence or venous reflux is not easily diagnosed by venography and therefore has to be done before this procedure is carried out.
