Filter by:The study aims to document the flow of German patients with cancer and acute deep vein thrombosis from first visit to diagnosis and treatment, the applied diagnostic procedures, and therapy modalities.
This is an observational study to analyze the influence of surgery duration and tourniquet time in the incidence of deep venous thrombosis (DVT) in patients that had undergone total knee arthroplasty (TKA).
Patients with cancer have a high risk of developing venous blood clots or thromboembolism (VTE). In an effort to target patients at highest risk of VTE for thromboprophylaxis (protective treatment for blood clots), numerous studies have identified serum biomarkers for risk of future VTE. There is also increasing evidence pointing to a prophylactic effect of statin therapy on the risk of developing VTE in high-risk populations including patients with advanced cancer. The purpose of this research study is to find out whether treatment with rosuvastatin (the study drug) reduces the risk of VTE in patients with cancer receiving chemotherapy. This study is specifically investigating the impact of rosuvastatin therapy on serum biomarkers (D-dimer and others) that indicate a risk for VTE, as well as safety and tolerance of rosuvastatin therapy in this population. This is a phase II randomized crossover study with two 3-4 week treatment periods during which all enrolled patients will receive 20 mg of rosuvastatin once a day by mouth or a matching placebo tablet. Approximately two tablespoons of blood will be collected for biomarker analysis at the beginning and end of each treatment period. After the first treatment period there will be a 3-5 week break where subjects will undergo a washout. Following this washout period every subject will "crossover" or begin taking the alternative therapy so everyone enrolled will receive the study drug either during the first or the second treatment period. Biomarker levels will be analyzed in both treatment periods and compared to baseline, with every patient acting as their own control.
The objective of this study is to evaluate the efficacy, safety, pharmacokinetics (PK) and pharmacodynamics (PD) of two different dosages of rivaroxaban in the treatment of deep vein thrombosis (DVT) and the prevention of the occurrence and the recurrence of DVT or pulmonary embolism (PE) in Japanese patients with acute symptomatic DVT without symptomatic PE.
Deep vein thrombosis (DVT) remains a life-threatening complication of arthroplasty. It remains controversial for anticoagulation strategies after total hip arthroplasty (THA). A randomized double-blind study was conducted to determine whether prophylactic anticoagulation was efficient reduce DVT after THA. subjects who underwent uncemented THA were assigned to prophylactic anticoagulation group or non- prophylactic anticoagulation group. Patients were followed up 3 months later after surgery. DVT was tested by contrast venography. Investigator also used logistic regression analysis with variable selection for obtaining the prediction model of DVT. DVT after THA was affected by personal (age) and clinical factors (mechanical compression, duration of surgery). THA with short duration of surgery did not require prophylactic anticoagulation.
Clots that develop in the deep veins of the legs or the lungs can result in pain, heart and lung disease and may lead to death if unrecognized or not treated. Risk factors for developing clots include surgery, hospitalization and/or being immobile. Up to 10 to 40% of people may develop a clot during or after their hospital stay or surgery, and sometimes these clots do not cause symptoms. In order to help reduce the risk of developing a clot in the legs or lungs, many people undergoing surgery receive a small dose of a blood thinner in hospital after their surgery is completed. Although prescription of a low dose blood thinner is routine practice after most surgeries, the risk or benefit of blood thinners after kidney transplant surgery is still not clear. Given this, many transplant physicians differ in prescribing practices of low dose blood thinners after kidney transplant surgery. More information is needed about the risk of clotting and bleeding in people after kidney transplant surgery so that physicians can become more unified in deciding whether a low dose blood thinner would protect patients after kidney transplant without producing harm. The REPORT study is designed to examine the risk of clotting in the legs or lungs in people after kidney transplant surgery as well as the risk of bleeding. Ultrasounds of the legs will be performed at various time points after surgery for up to one year to screen for blood clots. People participating in this study will also be screened and monitored for bleeding after surgery. Although this study will also examine the prescription practices of physicians, no blood thinners will be given or withheld from participants as a result of this study. Physicians will prescribe blood thinners as per their usual practice after kidney transplant. Overall, the goal of the study is to find out how frequent clotting and/or bleeding is after kidney transplant surgery, which will help in making recommendations regarding the use of low dose blood thinners in people after their surgery. Ultrasound scanning of the legs is a safe test that does not cause physical pain and has no risk of causing injury. Participation in this study will provide the benefit of additional monitoring with several ultrasound tests after surgery, screening for clots in the legs which can cause health risks and even death if unrecognized. If a clot is found, it will be treated promptly and according to current medical standards under the care of a specialist. In the long term, the results of this study will help improve health care delivery to people undergoing kidney transplant with the goal of decreasing potential complications such as clotting and/or bleeding. Currently, there are no guidelines available to guide physician's in the use of a low dose blood thinner after kidney transplant surgery. This study will help determine the risk of clotting or bleeding and help us make recommendations that will reduce potential risks and complications for people undergoing kidney transplant in the future.
The Angel™ Catheter combines the functions of a vena cava filter and a multi-lumen central line catheter. The device is designed to be placed in the inferior vena cava via the femoral vein for the prevention of Pulmonary Embolism (PE) and for access to the central venous system. The primary endpoint is freedom from serious adverse events (SAE), defined as death, symptomatic pulmonary embolism or major bleeding .
Pregnant women with a prior history of venous thromboembolism (VTE) are at increased risk of recurrent VTE. Current guidelines assessing the role of prophylaxis in pregnant women with prior VTE are based primarily on expert opinion and the optimal clinical management strategy remains unclear. This multicentre, prospective cohort study aims to test the following hypotheses: 1. Antepartum prophylaxis with fixed-dose low molecular-weight heparin (LMWH) is safe, convenient and associated with an acceptably low risk of recurrent VTE in women with a single prior episode of VTE that was either unprovoked or associated with a minor transient risk factor. (Moderate risk cohort) 2. Withholding antepartum prophylaxis is safe (recurrence risk <1%) in pregnant women with a single prior episode of VTE provoked by a major transient risk factor. (Low risk cohort) All study patients will receive 6 weeks of postpartum prophylaxis.
The objectives of the study are: o Objective ultrasound: Determine the presence or absence of subclinical DVT in practicing ultrasound-Doppler Day7 and Day35, patients who underwent TKA or THA o Clinical objective To evaluate the efficacy and tolerability clinical Enox ® in these patients compared with the original drug Lovenox ®.
This study seeks to determine the rate of thromboembolic complications (blood clots), including death attributed to thromboembolic disease, when anticoagulation (blood thinner) therapy is withheld from pregnant patients suspected of deep vein thrombosis (DVT) after a whole-leg compression ultrasound shows no DVT. Patients are followed for three months after the ultrasound to determine if a blood clot is diagnosed during that time.
