View clinical trials related to Iliac Vein Obstruction.
Filter by:Chronic obstruction of the iliac veins or inferior vena cava can occur as a result of deep vein thrombosis (DVT), or due to extrinsic compression in non-thrombotic iliac vein lesions (NIVLs). This obstruction can manifest as post-thrombotic syndrome (PTS) after DVT or as chronic venous disease (CVD) in NIVL. Despite sparse evidence, rates of venous stenting for PTS and NIVLs are increasing. A pragmatic, observer-blind, multi-centre, randomised-controlled trial for adults with CVD secondary to either PTS or NIVLs randomised to either best endovenous therapy (including venoplasty and deep venous stenting) or standard therapy (compression +/- anticoagulation). Included participants will have chronic venous disease (CEAP classification 3 - 6) secondary to proximal deep venous disease. The primary outcome is severity of venous disease at 6 months as ascertained by the Venous Clinical Severity Score (VCSS).
To evaluate the efficacy and safety of combination of anticoagulant and antiplatelet therapy on the patency of iliac vein at 12-month post stenting in patients with acute proximal DVT and ipsilateral iliac vein stenosis who received percutaneous mechanic thrombectomy and iliac vein stenting.
- Determine the sensitivity, specificity and accuracy of vascular ultrasound, using direct and indirect ultrasonographic signs, in the obstructive diseases of iliac venous segment, in patients with advanced chronic venous insufficiency (CEAP 3-6), considering the intravascular ultrasound (IVUS) as the gold standard for this diagnosis. - Develop an algorithm for noninvasive ultrasound investigation of obstructive lesions in the iliac segment in patients with advanced chronic venous insufficiency (CEAP 3-6).
About 90 % of vascular symptoms affecting the lower limbs consist of venous diseases. Its highest incidence occurs from the second decade of life, affecting significantly the economically active population. Chronic Venous Insufficiency treatment aims to relieve symptoms, treat and prevent complications, prevent recurrences and provide cosmetic satisfaction with minimal side effects. It's current treatment includes some classic postural measures (leg elevation), elastic stockings and bandages compression therapy and possible medication (phlebotonics). The results in the medium and long term are unfavorable, since a large number of patients do not get better or evolves with recurrence of symptoms. Nowadays many, no prospective , not randomized , international studies have shown favorable results with endovascular treatment of obstruction in the iliac vein territory in patients with advanced Chronic Venous Insufficiency . The purpose of this prospective, double-blinded randomized study is to evaluate the results obtained with endovascular treatment, through the use of angioplasty and stenting in this group of patients when compared with clinical treatment .
