A Prospective, Multicenter, Single-Arm Trial of Peripheral Vein Thrombectomy Stent System in Deep Venous Thrombosis

To evaluate the safety and efficacy of peripheral vein thrombectomy stent system produced by Shanghai Tendfu Medical Technology Co., Ltd. in the treatment of acute or subacute deep venous thrombosis.

Padua Prediction Score for VTE Risk in Thoracic Surgery Patients

The goal of this observational study is to assess the predictive accuracy of the Padua Prediction Score (PPS) for venous thromboembolism (VTE) risk in thoracic surgery patients. The study aims to answer the following question: Does the PPS provide a more accurate prediction of VTE risk? Participants will: Have their VTE risk assessed using the PPS during their hospital admission.

Predictive Value of Modified Caprini Score and D-Dimer in Managing Lower Limb Venous Thrombosis in Cardiothoracic Patients

The goal of this observational study is to evaluate the predictive efficacy of the Modified Caprini Risk Assessment Score and D-Dimer in identifying and managing lower extremity venous thrombosis (LEVT) among cardiothoracic surgery patients in Baghdad. The main questions it aims to answer are: Does combining the Modified Caprini Score with D-Dimer improve the accuracy of predicting lower extremity venous thrombosis (LEVT) compared to using each tool independently? Can these tools effectively guide clinical decisions for lower extremity venous thrombosis (LEVT) prevention and management in this patient population? Participants will: Undergo risk assessment for lower extremity venous thrombosis (LEVT) using the Modified Caprini Score and have their D-Dimer levels measured during their hospital stay. Be monitored for clinical outcomes, including confirmed lower extremity venous thrombosis (LEVT) incidence, need for anticoagulation therapy, and complications such as pulmonary embolism or recurrent thrombosis.

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

Clinical Application of Wearable Ultrasound Sensors

This study aims to develop and evaluate a wearable ultrasound imaging sensor for the early diagnosis and real-time monitoring of various diseases, such as cardiovascular conditions and structural abnormalities of superficial organs. With advancements in medical technology, wearable devices have attracted increasing attention for their portability and real-time capabilities.

This Research Proposal Focuses on Evaluating the Effectiveness of a Nursing Care Protocol in Preventing Deep Vein Thrombosis (DVT) in Patients Undergoing On-pump Cardiac Surgery. The Study Will Include an Intervention Group That Receives the Nursing Protocol and a Control Group That Receives Routine

The primary focus of this research proposal is to examine the efficacy of a nursing care protocol in preventing the occurrence of deep vein thrombosis (DVT) in patients undergoing on-pump cardiac surgery. The investigation will encompass an experimental group that will be subjected to a specific intervention, alongside a control group that will adhere to conventional care procedures. The central objective is to exhibit a statistically significant decrease in the incidence of DVT within the experimental group in comparison to the control group. The secondary outcomes involve assessing the severity of DVT instances and the development of associated complications. The proposed research strategy entails delineating the criteria for selecting participants, outlining methodologies for gathering data, and detailing statistical approaches for analysis. The amassed data will undergo scrutiny through suitable statistical examinations, including chi-square tests, t-tests, or Mann-Whitney U tests, as well as logistic regression analysis. The process of data analysis will involve descriptive statistics, comparative assessments, regression analysis, and subgroup scrutiny. The interpretation of outcomes will be contextualized within the framework of the research objectives and pre-existing scientific knowledge. The ultimate objective of this study is to enhance the existing understanding of DVT prevention, provide clinically grounded recommendations supported by evidence, and elevate the quality and safety of patient care.
