May-Thurner SyndromeThe purpose of this study is to evaluate the efficacy and safety of rivaroxaban for the prevention of deep vein thrombosis in patients with left iliac vein compression treated with stent implantation.
Anticoagulant Plus Antiplatelet Therapy Following Iliac Vein Stenting
Deep Vein ThrombosisIliac Vein Thrombosis3 moreTo 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.
Venous Stent for the Iliofemoral Vein Investigational Clinical Trial Using the DUO Venous Stent...
May-Thurner SyndromeDeep Vein Thrombosis1 moreThis is a prospective, multi-center, single-arm, non-blinded clinical trial designed to investigate the safety and efficacy of the Vesper DUO Venous Stent System as compared to a pre-defined performance goal (PG) established from published, peer reviewed scientific literature related to stenting of iliofemoral venous outflow obstructions.
Vascular Lab Resource (VLR) Biorepository
Cardiovascular DiseasesMetabolic Disease14 moreThis is a study of biomarkers obtained from prospectively collected subject samples and their correlation with cardiovascular and metabolic diseases. The purpose of this initiative is to develop an enduring tool to allow for collaborative research between clinicians at Cleveland Clinic Main Campus and basic scientists at the Lerner Research Institute. This collaboration will allow resources to be available to clinical and basic researchers alike. This tool will enable research of vascular disease in the Vascular Lab and will leverage this valuable asset to the fullest extent to allow for interdepartmental collaboration.
Iliac Vein Stenting in Advanced Chronic Venous Insufficiency
Iliac Vein ObstructionMay-Thurner Syndrome1 moreAbout 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 .
BARD® The VENOVO™ Venous Stent Study for Treatment of Iliofemoral Occlusive Disease
May-Thurner SyndromePeripheral Vascular Disease2 moreThe BARD® Venovo™ Venous Stent Study is a non-randomized clinical study intended to collect confirmatory evidence of the safety and effectiveness of the Venous Stent for the treatment of iliofemoral occlusive disease.
Prevalence of May-Thurner Syndrome in 1st-degree Relatives of Symptomatic Patients
May-Thurner SyndromeThe aim is to assess the prevalence of May-Thurner syndrome in 1st-degree relatives of previously identified symptomatic patients.
Treatment of the Postthrombotic Syndrome With the Oblique Stent - TOPOS Study
Post-thrombotic SyndromeIliac Vein Compression SyndromePrimary objective: To assess the efficacy of the stents (sinus-Obliquus stent for the common iliac vein, the sinus-XL Flex stent or sinus-Venous stent for the external iliac and common femoral veins) by evaluating different gradations of patency rates, patient's rating of disease severity and quality of life in patients with post-thrombotic syndrome and concomitant common iliac vein compression. Secondary objective: To assess long-term safety of venous stenting
The Efficacy and Safety of Interventions on the Pelvic Veins in Pelvic Venous Disorders
Pelvic Venous DisordersPelvic Congestive Syndrome1 moreThis retrospective study will enroll patients with pelvic venous disorders who have undergone pelvic vein surgery and endovascular interventions. Three groups of patients will be formed. The first will include patients who underwent open retroperitoneal resection of the gonadal veins and endoscopic trans- and retroperitoneal resection of the gonadal veins. The second group will include patients who underwent embolization of the gonadal veins with coils, the third - patients who underwent stenting of the common iliac veins, or stenting of the iliac veins in combination with embolization of the gonadic veins with coils. Evaluation of the effectiveness and safety of interventions on the pelvic veins will be carried out by assessing the effect of the intervention on pelvic pain, morphological and functional state of the pelvic veins. The assessment of the safety of interventions on the pelvic veins will be carried out by assessing the severity of post-procedural pain, the frequency of complications of operations on the pelvic veins, and complications of anesthesia. In addition, the duration of pelvic vein interventions will be compared with the length of time the patient is in hospital. Based on the data obtained, an algorithm will be proposed for determining the choice of the method of interventions on the pelvic veins in patients with pelvic venous disorders.
Treadmill Pilot Study (Invasive Pressure Measurements in PTS)
Post-thrombotic SyndromeMay-Thurner SyndromePatients with unilateral post-thrombotic obstruction of the iliac tract and or common femoral vein, eligible for stenting are included. Intravenous pressure is measured in both dorsal foot veins and both common femoral veins. Patients are asked to undergo a standardised treadmill test (3.2km/h, 0% slope that increases by 2%/2min, maximum walking time 26 min). Painfree and maximum action radius are noted.
