NCT ID: NCT06180122 Completed - Clinical trials for May-Thurner Syndrome

The Use and Reproducibility of Duplex Ultrasound to Provide Indices of Left Common Iliac Vein Diameter

Start date: March 5, 2024
Phase: N/A
Study type: Interventional

The goal of this feasibility/pilot study is to investigate whether or not vascular ultrasound can be used to aid the diagnosis of May Thurner Syndrome, in adult patients presenting to the vascular department with unexplained left leg swelling. The main research objective it aims to answer are: - The diameter variation of the left common iliac vein based on posture, using duplex ultrasound. - To determine inter- and intra-observer variation of the diameter measurement of the left common iliac vein using duplex ultrasound. Participants will have an ultrasound scan performed on their abdomen by three different clinical vascular scientists, and will have each scan performed whilst lying supine on an examination couch and again when the couch is tilted to 45 degrees. Researchers will compare the results of symptomatic patients to asymptomatic patients, to see if there is a difference in the diameter of the left common iliac vein between these two groups.

NCT ID: NCT05628948 Recruiting - Clinical trials for Cardiovascular Diseases

Vascular Lab Resource (VLR) Biorepository

Start date: November 14, 2019
Phase:
Study type: Observational

This 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.

NCT ID: NCT05409781 Not yet recruiting - Clinical trials for May-Thurner Syndrome

Prevalence of May-Thurner Syndrome in 1st-degree Relatives of Symptomatic Patients

MTS
Start date: August 15, 2024
Phase:
Study type: Observational [Patient Registry]

The aim is to assess the prevalence of May-Thurner syndrome in 1st-degree relatives of previously identified symptomatic patients.

NCT ID: NCT05076448 Completed - Clinical trials for May-Thurner Syndrome

The Efficacy and Safety of Interventions on the Pelvic Veins in Pelvic Venous Disorders

ESIPV
Start date: September 30, 2014
Phase:
Study type: Observational

This study includes a retrospective and prospective 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.

NCT ID: NCT04694248 Recruiting - Clinical trials for Deep Vein Thrombosis

Anticoagulant Plus Antiplatelet Therapy Following Iliac Vein Stenting

Start date: November 3, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04580160 Active, not recruiting - Clinical trials for Deep Vein Thrombosis

Venous Stent for the Iliofemoral Vein Investigational Clinical Trial Using the DUO Venous Stent System

VIVID
Start date: November 30, 2020
Phase: N/A
Study type: Interventional

This 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.

NCT ID: NCT04067505 Recruiting - Clinical trials for May-Thurner Syndrome

Rivaroxaban for the Prevention of Deep Vein Thrombosis in Patients With Left Iliac Vein Compression - The PLICTS Study

PLICTS
Start date: May 18, 2020
Phase: Phase 3
Study type: Interventional

The 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.

NCT ID: NCT04024215 Recruiting - Clinical trials for Iliocaval Compression Syndrome

Role of IVUS in Management of Iliocaval Obstruction

Start date: May 2020
Phase:
Study type: Observational

To assess the role of IVUS in 1. Providing diagnostic important data as: luminal diameters, cross-sectional area, assessment of potential thrombus volume which enables optimal choice of appropriate angioplasty technique, endovascular device guidance, and their impact on procedural technical success and patency rates. 2. comparing diagnostic accuracy of intravascular ultrasound (IVUS) with multiplanar venography and CT venography for iliocaval obstruction.
