May-Thurner SyndromeMay-Thurner syndrome is compression of the left iliac vein by the artery crossing over it. This is normal anatomy, but in some people the artery presses on the vein enough to thicken the vein wall over time. Surgical exploration in two of these patients verified marked hypertrophy of the intima of the left common iliac vein that caused partial obstruction. Surgical repair resulted in great improvement. There is evidence that intimai injury may also take place in the form of a spur when the compression occurs over time. Despite many collateral vessels throughout the pelvis, significant compression can produce symptomatic edema. Anatomic findings at venography are characteristic of this syndrome. Hemodynamic pressure measurements are of ancillary help in confirming the diagnosis. In contrast to the right common iliac vein, which ascends almost vertically to the inferior vena cava, the left common iliac vein takes a more transverse course The differences in circumference of the ankle and calf from the left to the right were 2 and 1.5 cm, respectively, with only trace difference at the knee (Fig. 2). An ultrasound was done that showed no evidence of DVT. This condition may occur in adults or children. Surgical repair resulted in great improvement.These results are generally better compared with results in patients who have deep venous thrombosis before the compression is recognized.
