“…Technical success rates of venous stenting are very high with approximately 84-93 % in chronic postthrombotic iliac vein obstruction [29,45]. Technical success rates decrease to 66 % in postthrombotic lesions with total occlusion of the IVC [46].…”

“…Iliocaval obstruction and associated abnormalities can also be detected by magnetic resonance (MR) venography and computed tomography (CT) venography, which may replace invasive studies in the future [27,28]. Both, MR imaging and CT are suited, although not perfect, for diagnosing May-Thurner syndrome, with the left common iliac vein being compressed by the overlying right common iliac artery [29,30]. Among all imaging tests intravascular ultrasound (IVUS) appears to be most accurate in estimating the morphological degree and extent of iliac vein stenosis and visualizing details of intraluminal lesions, such as intraluminal trabeculation in postthrombotic vessels [31].…”

Chronic venous insufficiency (CVI) as an advanced stage of chronic venous disease is a common problem that occurs in approximately 1-5 % of the adult population. CVI has either a nonthrombotic (primary) or postthrombotic (secondary) cause involving reflux, obstruction, or a combination of both. The role of venous obstruction is increasingly recognized as a major cause of CVI, with obstructive lesions in the iliocaval segment being markedly more relevant than lesions at the levels of the crural and femoral veins. Approximately 70-80 % of iliac veins develop a variable degree of obstruction fol-

“…Compression of the left iliac vein with detailed anatomic description was later described by May and Thurner [44]. The overall prevalence of symptomatic MTS ranges from 18% to 49% among patients with left-sided lower extremity DVT [45]. It is predominantly seen in young to middle-aged females (20-40 years).…”

“…The presence of flow reversal in the ipsilateral internal iliac vein, depiction of multiple cross pelvic collaterals, and an enlarged ascending lumbar vein can all be seen secondary to the underlying chronic venous hypertension. Pressure gradients could be measured across the compression, with a gradient of .2 mmHg indicating haemodynamic significance [45,48].…”

Extrinsic venous compression is caused by compression of the veins in tight anatomic spaces by adjacent structures, and is seen in a number of locations. Venous compression syndromes, including Paget-Schroetter syndrome, Nutcracker syndrome, May-Thurner syndrome and popliteal venous compression will be discussed. These syndromes are usually seen in young, otherwise healthy individuals, and can lead to significant overall morbidity. Aside from clinical findings and physical examination, diagnosis can be made with ultrasound, CT, or MR conventional venography. Symptoms and haemodynamic significance of the compression determine the ideal treatment method.

“…May-Thurner syndrome was defined as severe compression causing intimal changes in the lumen of the left common iliac vein by the overlying artery (9). Mild compression of the vein that did not cause significant narrowing of the lumen with normal venous intima was not regarded as the syndrome but as mild compression.…”
