Veins which are suitable for pelvic vein embolisation
In the pelvis, there are only four veins that are involved in pelvic venous congestion (or 'pelvic congestion syndrome
') and that can cause:
vaginal varicose veins (varicose veins in the vagina)
vulval varicose veins (varicose veins at the entrance of the vagina - the vulva)
leg varicose veins coming from the pelvis
haemorrhoids (commonly known as piles)
Research from The Whiteley Clinic and The Imaging Clinic in the UK have shown that in women who have had children, varicose veins in the vagina, vulva and in the upper thighs are often related to problems in either the right or left ovarian veins
and/or the right or left internal iliac veins.
The ovarian veins
are very long veins that start at the ovaries and drain blood up to veins more or less at the level of the kidneys. When the valves in these veins stop working, blood falls back down the ovarian veins
(ovarian vein incompetence or ovarian vein reflux) causing varicose veins
in the pelvis (pelvic congestion syndrome
The internal iliac veins are very short and are often overlooked when veins are investigated. However research from the UK has shown that internal iliac vein reflux can allow blood to reflux into vaginal, vulval and leg varicose veins and also into haemorrhoids (piles).
The best way to diagnose which of these veins are not working and therefore need embolisation, is to perform a transvaginal duplex ultrasound scan
at a specialist unit. Nonspecialist units often use MRI, CT scanning or venography. Unfortunately none of these techniques are as accurate as transvaginal duplex ultrasound scanning
when performed by a properly trained expert.
When a patient has a problem with pelvic congestion syndrome
, vaginal varicose veins, vulval varicose veins
, some leg varicose veins
from the pelvis and some haemorrhoids from the internal iliac veins, a transvaginal duplex ultrasound scan
shows which of the veins are involved. Of the four veins described above, any number of them can be involved and occasionally all four can be involved.
Any of these for veins are suitable for pelvic vein embolisation (or embolization).
