Iliac vein compression, within the vascular context, refers to the narrowing or compression of the iliac vein, often the left common iliac vein, by an overlying artery, typically the right common iliac artery. This anatomical impingement can impede venous blood flow, leading to various clinical manifestations such as leg swelling, pain, and an increased risk of deep vein thrombosis (DVT). Understanding this condition, also known as May-Thurner syndrome, is crucial for accurate diagnosis and patient management in medical settings.
In medical ultrasound, identifying iliac vein compression is vital for vascular specialists. Doppler ultrasound can visualize reduced blood flow, post-stenotic turbulence, and the actual compression site, aiding in diagnosis. Precise imaging helps differentiate this mechanical compression from other causes of venous insufficiency, guiding treatment strategies from conservative management to stent placement.
