Filter by:Post-thrombotic syndrome (PTS) is the most common chronic complication of deep vein thrombosis (DVT), with major consequences for patient quality of life and cost of management. Identifying patients at high risk of developing PTS could be useful for its prevention and may lead to more appropriate therapeutic strategies to reduce its incidence and severity. Prognostic tools for predicting risk are very useful for choosing the optimum treatment and improving patient management and are a preliminary step before developing predictive models useful for determining sensitivity to treatment. At present, although several prognostic markers and models have been proposed, it is still difficult to predict who will develop a PTS or a moderate to severe PTS. The development of PTS is multifactorial and depends largely on the extent and severity of venous obstruction which supports the theory of thrombosis burden (DVT-Burden) as a potential prognostic marker for PTS. It therefore seems important to study the association between thrombosis burden and the occurrence of PTS. The Venous Volumetric Index or VVI (Ouriel 1999) will be used for quantifying DVT-Burden. The VVI was constructed by calculating the volume from the diameter and length of 14 venous segments from the calf veins to the inferior vena cava. The VVI has been validated for its ability to discriminate between symptomatic and asymptomatic DVT and has shown superior performance to other methods for quantifying DVT. This study aim to assess the performance of baseline DVT-burden estimated by the VVI score on ultrasound for predicting the occurrence and the severity of PTS as assessed by the Villalta scale at 6 months.
Patients who have a peripherally-inserted central catheter (PICC) placed are at a risk of developing a deep vein thrombosis (DVT). At TriHealth, approximately 2-4 patients per month who have a PICC placed experience a subsequent DVT. One innovative way to possibly mitigate the risk of DVTs is hand grip exercises. The current study will be the first study to evaluate hand grip exercises for the prevention of DVTs in adult patients hospitalized in the United States.
The aim of this multicenter randomized clinical trial is to compare the tunneling technique of PICC insertion with the non-tunneled insertion technique in the incidence of the combined or isolated outcome of catheter-related bloodstream primary infection, thrombosis, obstruction, and accidental dislodgement in the adult population within a period of up to 30 days.
Insertion of intravenous catheter is a very common operation in patients in the general intensive care unit. These catheters are used for a variety of purposes - administration of inotropics/pressors, intravenous nutrition, concentrated electrolytes and performing dialysis.There are several known complications of central venous catheter insertion, such as thrombosis and pulmonary embolism. In a literature review, there are no clear data regarding the rate of intravenous thrombosis in patients after removal of a central venous catheter. These findings are often discovered randomly, when the patient undergoes imaging for a different indication. There is no recommendation for an active search for intravenous thrombi at the catheter insertion sites in these patients, and it is not entirely clear whether it is mandatory to administer anticoagulant treatment in these patients if thrombi are randomly discovered at the catheter insertion sites. In this study, we aim to check the proportion of patients who developed thrombosis at the central catheter insertion sites after its removal, to check whether there are catheter insertion sites that are at a higher risk of developing thrombosis than other sites, and to check whether there are predictive characteristics for the development of this type of thrombosis.
The aim of this study is to evaluate the efficacy and safety of rheolytic thrombectomy in restoring venous patency DVT, periprocedural complications and development of PTS after tratment of iliofemoral DVT.
The JETi Hong Kong PMS is a prospective, single-arm, multicenter study to collect real-world data on the safety, performance, and clinical benefits of the JETi System for the treatment of acute and subacute thrombosis in the lower extremity peripheral vasculature. This is a post-market study that will register approximately 20 subjects at approximately 5 centers in Hong Kong. Subjects participating in this study will be followed for up to 30 days after the JETi procedure.
The purpose of this study is to evaluate the comparative effectiveness of nadroparin versus transjugular intrahepatic portosystemic shunt in cirrhotic patients with refractory asymptomatic portal vein thrombosis using a design of a multicenter, randomized controlled trial
A single site study evaluating the safety, feasibility, and effectiveness of percutaneous large-bore mechanical thrombectomy using the Inari Triever Aspiration Catheter for the treatment of portomesenteric vein thrombosis (PMVT).
This is a physician-initiated, observational, monocentric, retrospective and prospective Study. The study is intended to assess the feasibility of mechanical thrombectomy of caval and iliofemoral veins according to normal clinical practice in adult patients with symptomatic acute or subacute ileofemoral or caval deep vein thrombosis objectively diagnosed with CT scan imaging.
The objective of this retrospective, prospective, multicenter cohort study is to determine the risk factors for deterioration of CVT patients after admission and establish a scoring model for risk stratification of patients. This study included two stages, the first stage was to enroll CVT patients from a single center from 2017 to 2022 for modeling, and the second stage was to enroll CVT patients from three centers in 2023 for external validation
