Iliac vein stenosis increases left-sided deep vein thrombosis (DVT) risk in women used combined oral contraceptive (COC)

Up to 25% of people in the healthy population have underlying stenosis for greater than 50% of the left common iliac vein.

However, for women who have significant venous stenosis of the common iliac vein, who also use combined oral contraceptives (COC), they are at higher risk of deep vein thrombosis (DVT) than average risk.

According to recent findings, every 1% increase in iliac vein stenosis (greater than 70%) increased the risk of DVT by 5%. And those who also use COC, the odds ratio of DVT increase to 5.46% for every 1% increase in stenosis.

This conclusion based on evaluated 35 DVT’s women with computed tomography or magnetic resonance imaging and 35 age-matched control women who presented to the emergency room with abdominal pain.

Reported in the American Journal of Obstetrics and Gynecology on July 11, 2011, the study authors concluded that iliac vein stenosis should be concerned when young woman develops left-sided DVT without indications other risk factors after using COC.

    These are some fascinating statistics. Every 1% increase in IVS contributes to a 5% risk increase in stenosis is scary! Hopefully articles like this will get out to women who are taking contraceptives!
