Introduction A web-like lesion at the iliocaval junction was described by McMurrich, a Canadian physician, in 1908. Recognition of the lesion now commonly known as May–Thurner syndrome (MTS), or iliac compression syndrome, evoked a series of controversies from the start.…
Percutaneous endovenous stenting has emerged as a powerful technique for treating chronic venous obstructions. Stenosis and chronic total occlusions (CTOs) are amenable to endovascular correction. The technique is minimally invasive, safe, and effective and does not preclude open correction in…
The endovascular approach to venous obstructive lesions including stenoses and chronic total occlusions (CTOs) has replaced traditional open surgery. As a result, a broader spectrum of patients with comorbidities that might otherwise preclude an open approach have benefited. In addition,…
Volume-Pressure Curve The volume-pressure (V-P) curve is central to venous hemodynamics. Its effect is manifest in many aspects of venous function. Because veins are thin-walled collapsible tubes, the V-P curve is governed by the Tube law, which is displayed in…
