Rare forms of Venous Diseases:

May Thurner Syndrome, Pelvic Congestion Syndrome and Klippel Trenaunay Syndrome.

May Thurner Syndrome is an infrequent condition where the internal iliac artery crosses over the iliac vein and compresses the soft vein causing a partial blockage with an increased resistance to normal outflow resulting in venous hypertension and ultimately thrombosis of the iliac vein. For anatomic reasons this more frequently involves the left leg in women but it can also occur in men and sometimes it will affect the right leg. The compression of the vein is at the level of the pelvic vessels and this may make it difficult to appreciate on conventional duplex ultrasound examination. This condition can lead to chronic swelling, varicose veins and non healing ulcers. Now interventional specialists have a variety of enzymatic and mechanical devices (angioplasty and stents) to clear out clot and open the damaged vein to relieve symptoms.
