DEFIANCE: RCT of ClotTriever System Versus Anticoagulation In Deep Vein Thrombosis

This study is a prospective, multicenter, randomized controlled trial of an interventional strategy using the ClotTriever System to achieve and maintain vessel patency (ClotTriever Intervention Arm) versus conservative medical management using anticoagulation therapy alone (Conservative Medical Management Arm) in the treatment of subjects with symptomatic unilateral iliofemoral DVT. The study will collect data on demographics, comorbidities, details from the DVT diagnosis and treatment, and clinical outcomes through the 6-month follow up visit.

Outcomes of Iliac Vein Stenting With Dedicated Venous Stents in Treatment of Chronic Post-thrombotic Venous Ulcers

Outcomes of iliac vein stenting with dedicated venous stents in treatment of chronic post-thrombotic venous ulcers Deep vein thrombosis (DVT) affects 1 to 3 individuals per 1000 annually. Among these patients, 20% to 50% may develop post-thrombotic syndrome (PTS), with the likelihood varying based on the extent and location of the thrombus. Notably, despite receiving anticoagulation therapy, 5% to 10% of patients may progress to severe PTS, potentially leading to the development of venous ulcers (Afsha Aurshina, 2018). Chronic venous obstruction (CVO) refers to the impediment of venous flow, typically resulting from either partial or complete blockage of the venous system. This obstruction leads to diminished venous flow and elevated pressure within the affected veins. CVO serves as a broad descriptor for various conditions, including post-thrombotic syndrome (PTS) and nonthrombotic iliac vein lesions (NIVLs). PTS commonly arises as a complication of deep vein thrombosis (DVT), with estimates indicating that up to 50% of patients diagnosed with iliofemoral DVT will develop PTS within two years following their initial diagnosis. (Mohammad E. Barbati, 2024) The study aims to know the outcomes of iliac vein stenting with dedicated venous stenting in the treatment of post-thrombotic syndrome venous ulcer. Type of Study: Prospective single arm cohort study * Study Setting: Ain Shams University hospitals * Study Period: 2 years with 6 months follow up * Sample Size: 20 patients. * Study Population Patients presenting to the outpatient clinic at Ain Shams University Hospitals with venous ulcers. * Study Tools * 20 patients will be selected. * Written informed consent. * Full history taking, personal history , risk factors of DVT, presence of any medical illness , assessment of QOL based on CVIQ 20 - questionnaire, list of symptoms, sensations or types of discomfort that you may or may not be experiencing and which may make everyday life hard to bear to a greater or lesser extent. * Clinical evaluation: based on revised Venous Clinical Severity Score rVCSS , Villalta score and CEAP classification . rVCSS includes 10 items, such as pain, varicose veins, oedema, skin pigmentation, inflammation, skin induration, number of active ulcers, ulcer size, duration of ulcer, and application of pressure therapy. Each item is scored from 0 to 3 according to the severity, and the total score is 30. A higher score indicates higher severity. And using villlata score It can be used to both diagnose and categories the severity of the condition. The Villalta score involves both the patient who grades the presence and severity (0-3 points) of five symptoms ( pain , cramps, heaviness, parasthesia and pruritus ) and and the physician who grades six clinical signs(Pre-tibial oedema, Hyper-pigmentation, Redness, Venous Ectasia, ain on calf compression, ulcers) (0-3 points) after examination of the lower limb. Also the clinical severity of the venous disease will be graded according to the clinical, etiological, anatomical, and pathophysiological (CEAP) scoring system, and assessment of venous ulcer assessment (by onset, course, duration, site, size, shape

Incidence and Characteristic of CRT Persistent After Catheter Extraction in ICU Patients

The goal of this observational study is to describe characteristics of catheter related thrombosis (CRT) that persists after catheter extraction in condition of intensive care unit. The main questions it aims to answer are: 1. What is the incidence of CRT that persists after catheter extraction in patients hospitalized in the intensive care unit? 2. What are the risk factors for this phenomenon? 3. What is the fate of such a thrombus, including recanalization or the development of complications such as pulmonary embolism or post-thrombotic syndrome?

Design and Rationale of the COLT Study

Deep vein thrombosis (DVT) is a condition in which a blood clot forms in the deep veins of the leg and can lead to long-term problems such as leg pain, swelling, and reduced quality of life. Standard treatment with blood-thinning medication lowers the risk of complications, but some patients still develop long-term damage to the veins. Inflammation is thought to play an important role in these complications. This study will evaluate whether adding colchicine, an anti-inflammatory medication already used for other conditions, to standard anticoagulant therapy can improve outcomes in patients with acute DVT. Participants will be randomly assigned to receive either colchicine or a placebo, in addition to usual blood-thinning treatment, and will be followed for one year. The main goal of the study is to determine whether colchicine reduces the risk of developing long-term vein problems after DVT. The study will also assess the risk of new blood clots, vein recovery, quality of life, and the safety of colchicine treatment.

Statins for Venous Event Reduction in Patients With Venous Thromboembolism

The standard or usual treatment for patients diagnosed with deep vein thrombosis or pulmonary embolism is treatment with blood thinners (called anticoagulants). While treatment of blood clots with blood thinners is effective, some research has shown that adding a statin (medication used to lower cholesterol) may give extra protection. It is thought that statins can improve how cells along the walls of the vein control inflammation, which can prevent new blood clots from forming. The medication in this study, rosuvastatin, is approved in Canada for use as a cholesterol-lowering medication. The use of rosuvastatin in this study is considered investigational. This means that Health Canada has not approved the use of rosuvastatin as a treatment for blood clots. However, it has been approved for use in this research study. The purpose of this study is to examine if adding a statin (rosuvastatin) to the usual blood thinner treatment will decrease the risk of another blood clot forming. The investigators also hope to discover if taking a statin reduces damage to your veins. To do this, some of the participants in this study will get rosuvastatin and others will receive a placebo (a substance that looks like the study rosuvastatin but does not have any active or medicinal ingredients). The placebo in this study is not intended to have any effect on your blood clot. A placebo is used to make the results of the study more reliable.
