199 Clinical Trials for Various Conditions
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.
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.

Deep Vein Thrombosis, DVT
The goal of this study is to determine the safety and tolerability or efficacy of adjunctive treatments (including rosuvastatin 20 mg daily) in combination with standard anticoagulation therapy (Factor Xa inhibitors) in patients with lower extremity deep vein thrombosis (DVT). The efficacy of adjunctive treatments to prevent the development of post thrombotic syndrome (PTS) after DVT will be evaluated.
Post-thrombotic Syndrome, Deep Vein Thrombosis Leg
The goal of this study is to examine in vivo thrombosis characteristics with ultrasound shear wave elastography (SWE) and determine the relationship with thrombus resolution and postthrombotic syndrome (PTS) in patients with acute proximal Deep Vein Thrombosis (DVT).
Deep Vein Thrombosis
Post-thrombotic syndrome (PTS) is a complication that can develop after deep vein thrombosis (DVT) of the lower extremities. PTS can occur at various times after the initial episode, but usually manifests within two years of initial DVT onset. Early and more complete thrombus clearance is believed by many to relieve venous outflow obstruction, preserve valvular function and reduce venous hypertension. Two previously published randomized controlled trials, the CAVENT trial and the ATTRACT trial, were larger and designed to investigate the efficacy of CDT. However, both of these trials included patients with iliofemoral as well as femoro-popliteal deep vein thrombosis. Our study will be limited to patients with iliofemoral deep vein thrombosis to assess whether Pharmacomechanical catheter-directed thrombolysis (PCDT) therapy utilizing AngioJet and tPA can safely and effectively reduce post thrombotic syndrome after 24 months.
Deep Venous Thrombosis, Post Thrombotic Syndrome
This is a prospective cohort study of 30 patients who are 8-21 years of age with venous thromboembolism (VTE)- either lower extremity deep venous thrombosis (DVT) or pulmonary embolism (PE).
Deep Vein Thrombosis, Pulmonary Embolism
The purpose of this study is to evaluate the effectiveness of a new leg compression device in preventing post-surgical deep vein thrombosis (blood clot) that can occur after major and complex spine surgery. The investigators aim to show that this new compression device is no worse than the standard sequential compression device (SCD) at preventing DVT and may be able to detect deep vein thrombosis in patients who are not typically screened for this diagnosis after surgery. This new device may be able to capture an important post-surgical complication while providing a more comfortable treatment option.

Deep Vein Thrombosis
This study will examine the effectiveness of pre-recorded instructional videos in the use of bedside ultrasonography to ascertain the presence of a lower extremity deep venous thrombosis (DVT) as compared to in-person lectures and hands-on training.
Deep Vein Thrombosis, Pulmonary Embolism
The Researchers are studying whether a vascular boot warming program plus standard of care anticoagulation can be a safe and effective method to resolve Deep Vein Thrombosis (DVT) ±Pulmonary Embolism (PE) earlier and prevent development of post-thrombotic syndrome (PTS). Additionally, to learn whether a more detailed imaging of the affected lower extremities will provide a more accurate and reliable method to guide treatment for this condition.
Acute DVT of Lower Extremity
This study will assess the safety and effectiveness of a drug called apixaban for the treatment of upper extremity deep vein thrombosis (UEDVT) and clinically important bleeding. Subjects will receive apixaban 10 mg by mouth twice a day for 7 days, followed by 5 mg by mouth twice a day for a duration of 11 weeks. There will be a followup visit at 12 weeks for all participants. A total of 375 are to be enrolled. The study drug has been approved to treat blood clots. The study drug has not been studied uniquely for the treatment of blood clots in the upper extremity however. Because it is unknown whether it is effective to treat blood clots in the upper extremity, the principal investigator cannot guarantee that there will be benefit to study subjects; however, it is hoped that the information obtained from this research study will help treat patients in the future.

Deep Vein Thrombosis, Venous Thrombosis
Study hypothesis: Subcutaneous enoxaparin is more effective than subcutaneous heparin in preventing the development of DVT in the general surgical intensive care unit population. Hospitalized patients are at increased risk for the development of blood clots in the legs, known as deep venous thrombosis (DVT). Surgical patients are in a higher risk category than the general hospital population due to a number of factors including undergoing surgery and increased risk of immobility. The highest risk patients are in the surgical intensive care unit, where their surgical risks for blood clots are combined with issues such as sepsis, acquired blood clotting disorders, and increasing age, each of which are factors that contribute to the risk of blood clot development. 1. Patients who develop these blood clots (DVTs) are at risk for chronic leg swelling, pain, and in some cases, chronic ulcer development on the leg. In the worst case scenario, these blood clots can break away and migrate to the lungs where they cause a pulmonary embolism (PE), a clot in the lungs that can cause significant breathing difficulty requiring intubation and mechanical ventilation, and in some cases, death. According to recent research, DVTs account for over 200,000 patient deaths each year nationwide. 2. A large amount of data has supported the use of medication called heparin or enoxaparin in low doses to prevent these blood clots from forming while in the hospital. Both of these medications are considered standard of care for use patients considered moderate and high risk for the development of DVT. 3. While both of these medications have been shown to significantly reduce the occurrence of DVT in appropriate doses, 4. there has never been a direct comparison of the two medications in the highest-risk population of the surgical intensive care unit. Our own preliminary data suggests patients may have a lower incidence of DVTs with the use of enoxaparin versus heparin. Part of the reason for this may be the requirement for three times daily dosing of the heparin compared to once daily dosing for enoxaparin. There may also be some inherent differences in the efficacy of the medications themselves.
Lower Extremity Deep Venous Thrombosis
Deep vein thrombosis (DVT) of the arm, officially called upper extremity DVT is a rare disorder and accounts for up to 1-4% of all cases of deep vein thrombosis. In case of a thrombosis, there is a blood clot in one of the veins, which should be treated with blood thinners (anticoagulants). The aim of the present study is to see whether it is safe to use a combination of tests for the diagnosis of arm thrombosis. In all patients, we will use a clinical decision rule (clinical judgement) and a laboratory test (D-dimer testing), in most patients also an ultrasound of the arm will be done. The combination of these tests was found to be safe and effective in patients with thrombosis of the legs.
Suspected Upper Extremity Deep Vein Thrombosis
The study's hypothesis is that there are some patients who come for surgery who have asymptomatic clots in their lower extremities upon their arrival to the hospital for their surgical admission. We will be performing duplex studies of the subjects' legs before their surgery to determine how often clots are present. We will also perform duplex scans of the legs after the subjects' surgeries to determine what factors (surgical, anesthetic, co-morbidities)are correlated with the development of DVTs.
Perioperative DVTs
Background Patients with cancer and a first deep venous thrombosis of the leg or pulmonary embolism (venous thromboembolism, VTE) are generally treated with low molecular weight heparin (LMWH)injections for 6 months, since this treatment is associated with a reduced incidence of recurrent VTE compared to vitamin K antagonists (VKA). It is recommended that patients with active malignancy (metastatic cancer and/or ongoing cancer treatment)continue anticoagulant treatment. However, it is unknown whether LMWH is still superior compared to VKA for the long-term anticoagulant treatment. Aim The aim of this study is to evaluate whether low-molecular-weight heparin more effectively reduces recurrent VTE compared to vitamin K antagonists in patients with cancer who have already completed 6 to 12 months of anticoagulant treatment because of deep venous thrombosis of the leg or pulmonary embolism. Hypothesis The investigators hypothesize that LMWH is more effective compared to VKA in the long-term treatment of VTE in cancer patients who have already been treated for 6-12 months with anticoagulants. Design This is a multicenter, multinational, randomized, open label trial. Patients Patients with a malignancy (all types, solid and hematological) who have received 6-12 months of anticoagulation for VTE and have an indication for continuing anticoagulation, will be randomly assigned to six additional months of LMWH or VKA. LMWH will be administered in a weight-adjusted scheme, with 65-75% of therapeutic doses. All types of LMWH and VKA are allowed, as long as weight adjusted dosing is possible for LMWH. The target INR will be 2.0-3.0. The primary efficacy outcome is symptomatic recurrent VTE, i.e. deep vein thrombosis and pulmonary embolism. The primary safety outcome is major bleeding. Sample size A total of 65 to 87 recurrent VTE events are needed to show a 50% reduction with LMWH as compared to VKA (type I error 0.05, two-sided, power respectively 80 and 90%). To observe 75 events, with a 10% event rate per half year in the VKA arm and 5% in the LMWH arm a total of 1000 patients will need to be included. Organisation Outcomes will be adjudicated by a central adjudication committee. A steering committee will be formed, preferably consisting of one member of every participating center. An electronic case report form will be used for data collection. Also, an electronic trial master file will be used.
