Filter by:After reports from observational studies suggesting an association between acutely ill medical patients and venous thromboembolism (VTE), interventional trials with anticoagulants drugs have demonstrated a significant reduction of VTE during and immediately after hospitalisation. Although several guidelines suggest the clinical relevance of reducing this outcome, there is a low tendency to use anticoagulants in patients hospitalised for acute medical illness. This observational multicentre study wants to evaluate the incidence of venous thrombo-embolism in acutely ill patients hospitalized in internal medicine wards.
The objective is to determine the incidence of thrombosis on central venous catheters in patients hospitalized in a surgical critical care unit, in the immediate postoperative period of urological or digestive carcinological surgery, and receiving parenteral nutrition.
No randomized head-to-head comparison between the individual Non-vitamin K Antagonist Oral Anticoagulants (NOAC) exists. The DANNOAC-VTE study is a nationwide cluster randomized cross-over study comparing efficacy and safety of the four NOACs, edoxaban, apixaban, rivaroxaban and dabigatran for oral anticoagulation in venous thromboembolism across Danish hospitals.
Cancer patients with Central Venous Catheter (CVC) Associated Deep Vein Thrombosis (DVT) will be treated with Low Molecular Weight Heparin (LMWH) and apixaban. Study duration is 12 weeks.
To clarify the effectiveness and safety of the direct factor Xa inhibitor rivaroxaban in domestic clinical use for patients with deep vein thrombosis and pulmonary embolism
The patients admitted in hospital who had midline catheter inserted in upper limb are followed-up for the presence of complications related to catheter introductions. The symptoms and signs of upper limb thrombosis are recorded. The diagnosis is confirmed by sonography examination. In the selected group of asymptomatic patients sonography examination is done 8 to 10 days after cathether insertion in order to detect the incidence of the asymptomatic thrombosis
Portal vein thrombosis (PVT) is defined as an obstruction of the portal vein. The prevalence of PVT is 10-25% and incidence is about 16% in cirrhotic patients. PVT leads to increased intrahepatic resistance, decreased portal velocities, splanchnic vasodilatation, and stagnant flow. Portal vein recanalization (PVR) with transjugular intrahepatic portosystemic shunt (TIPS) is aimed at restoring main portal vein (PV) flow in chronic PVT. In this study, we will review the safety and outcomes of this approach.
In neurosurgical patients, the risk for venous thromboembolic events (VTE) is high due to the relatively long duration of surgery, the high occurrence of prolonged immobilization of patients due to paresis of the legs or intracranial pathology causing inability to mobilise2. Moreover, intracranial and intraspinal tumours and subarachnoid haemorrhage cause hypercoagulability, which increases the risk on VTE. There is a high degree of diversity in attributed risk on thrombosis in the neurosurgical patient cohort. Due to this diversity, insufficient power of performed studies and lack of careful phenotyping and description of risk factors in previous studies on deep venous thrombosis (DVT) prophylaxis, as yet the optimal DVT prophylaxis in neurosurgery remains unclear. A prospective randomized study with adequate power and detailed information on patient related factors (malignancy, subarachnoid haemorrhage, prevailing coagulopathies), type of surgery, duration of surgery, and postoperative immobilisation will allow us to identify the optimal treatment strategy for high risk neurosurgical patients. In the current study all patients that fulfil the inclusion criteria will be subjected to post-operative systematic evaluation of VTE by echo-duplex investigation.
This is a prospective, randomized vanguard trial of trauma patients admitted to the trauma surgery service at Intermountain Medical Center who are deemed to be at high risk for venous thromboembolism. Once identified and enrolled, subjects will be randomized to receive bilateral lower extremity duplex ultrasound surveillance versus no surveillance. The study will compare the two groups with regard to deep vein thrombosis, pulmonary embolism, and major and clinically relevant bleeding episode rates, both during the index hospitalization and at 90 days post-discharge.
The purpose of this study was to compare the efficacy of Percutaneous mechanical thrombectomy (PMT) followed by standard anticoagulant therapy, with anticoagulation therapy alone, for the treatment of acute proximal lower extremity deep vein thrombosis.
