Evaluation of Cerebral Oxygenation and Hemodynamics in Patients With Cerebral Venous Thrombosis...

Cerebral Venous Thrombosis

Cerebral hypoperfusion and hypoxia are the major determinants of neurological outcomes following acute brain injury as proved in Traumatic Brain Injury/Sub Arachnoid Haemhorrhage literature. How the brain injury affects cerebral oxygenation in patients with CVT is not currently known. Some of the factors that can affect cerebral oxygenation in patients with CVT are Hemoglobin, PO2, PCO2, Cerebral Perfusion Pressure (or MAP) and change in Intracranial Pressure after Decompressive Craniectomy. This study is designed to study how these factors affect cerebral oxygenation and impact of Decompressive Craniectomy on the cerebral oxygenation.

Venous Thrombosis and Pulmonary Embolism

This study aims to collect patient reported outcomes and assess treatment satisfaction in active cancer patients treated with rivaroxaban for VTE (venous thromboembolism).

Extended Out-of-hospital Low-molecular-weight Heparin Prophylaxis Against DVT and PE in Patients...

Venous ThrombosisPulmonary Embolism1 more

Postoperative venous thromboembolism (VTE) is a significant health-care problem, resulting in significant morbidity, mortality and resource utilization. The true incidence is unknown, and may range from 1% to 15%. At the current time, the clinical practice of VTE prophylaxis in thoracic surgery includes administration of unfractionated or low molecular weight heparin starting at the perioperative period and finishing at the time of patients' discharge. In orthopaedic surgery, prolonged thromboprophylaxis beyond 10 days and up to 35 days has become the standard of care. There is a clear need to systematically evaluate the incidence of VTE after resection of lung malignancies and to evaluate the role of extended VTE prophylaxis in preventing Deep Vein Thrombosis (DVT) and pulmonary embolus (PE) after those major lung resections. This study will involve patients undergoing lung resection for malignancy at St. Joseph's Healthcare Hamilton and the University Health Network's Toronto General Hospital. The study will include 150 consecutively recruited patients. Study interventions will include Computed Tomography with pulmonary embolus (PE) protocol and bilateral extended leg Doppler Ultrasound for the detection of Deep Vein Thrombosis 30 days post-surgery. In summary, this study is aimed at evaluating, for the first time in a prospective manner, the actual incidence of DVT and PE in patients undergoing major lung resections for malignancies. The knowledge gained in this study will be used to inform a future investigation involving a Randomized Controlled Trial (RCT) to compare current post-operative thromboprophylaxis with an extended 30-day prophylaxis protocol with the hope of providing an evidence-based practice change in VTE prophylaxis care for this high risk population.

Management of Venous Thromboembolism in France: a National Survey Among Vascular Medicine Physicians...

SurveyVenous Thromboembolism3 more

In France, venous thromboembolic (VTE) disease is usually managed by vascular medicine physicians (VMP). The national OPTIMEV study, conducted more than 12 years ago among VMP practicing in hospital and in the community described the management of VTE in routine clinical practice. Since then a large number of practice changing studies have been published. This includes trials that have validated the use of direct oral anticoagulants (DOAC), the new standard of care of VTE, as per new national and international guidelines. Management of VTE in 2019 appears to be significantly different from the one that prevailed more than 10 years ago when the last national survey was conducted. It is therefore important to have an update on the routine clinical practice management of VTE by VMP. In this perspective the investigators aim to conduct a national survey among VMP practicing in France

A Practical Nomogram Based on Systemic Inflammatory Markers for Predicting Portal Vein Thrombosis...

Systemic Inflammatory MarkersPortal Vein Thrombosis

Immunothrombosis has recently been used to describe the responses/mechanisms in thrombosis. Systemic inflammatory markers are prognostic markers for a variety of thrombotic conditions; however, their potential value in predicting portal vein thrombosis (PVT) is unknown. This study aimed to establish an easy-to-use nomogram based on systemic inflammatory markers to predict portal vein thrombosis (PVT) in patients with liver cirrhosis.

Incidence of Venous Thromboembolism in Children Undergoing Elective Neurosurgical Procedures

Deep Vein Thrombosis

The purpose of this study is to determine how frequently children undergoing elective neurosurgical procedures develop blood clots in the deep veins of the legs while hospitalized. The information gained from this study will help us determine when children children need to receive therapy to help prevent this type of blood clot from forming.

Influence of Tourniquet Use and Surgery Duration on the Incidence of Deep Vein Thrombosis in Total...

Deep Vein Thrombosis

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).

Incidence of Superficial Vein Thrombosis

Superficial Vein Thrombosis

To date, the investigators still do not know the annual incidence of Superficial Vein Thrombosis in the legs, although the investigators do know that this pathology is frequent and the investigators can assume its incidence is greater than Deep Vein Thrombosis which is of 1 to 2 cases per year per 1,000 inhabitants. Furthermore, the high percentage of SVT with concomitant DVT and Pulmonary Embolism only concerns patients seen in vascular medicine, so it is important to re-evaluate this rate on an unselected population from general practice.

Global Anticoagulant Registry in the FIELD- Venous Thromboembolic Events

Venous ThromboembolismDeep Vein Thrombosis1 more

The protocol is a large registry to describe acute, sub-acute and extended duration of anticoagulation management, clinical and economic duration of anticoagulation management, clinical and economic outcomes in patients with treated acute VTE (DVT and PE) in the real-world setting. Main objectives are to clarify the: treatment related details for acute VTE (either conventional anticoagulation therapy, treatment with a direct oral anti-coagulant or other modalities of treatment) Rate of early and late symptomatic VTE recurrence Rate and nature of complications of VTE including post thrombotic syndrome and chronic thromboembolic pulmonary hypertension Rate of bleeding complications Rate of all-cause mortality at six months

Limited Compression Ultrasound by Emergency Physicians to Exclude Deep Vein Thrombosis

Deep Vein Thrombosis

Deep vein thrombosis is a common condition seen in the Emergency Department. Standard of care for diagnosis of DVT includes a combination of a clinical pre-test probability rule known as Well's criteria, D-dimer blood testing, and Radiology department ultrasound. The purpose of this study is to determine whether Emergency Physicians can safely rule out deep vein thrombosis using Well's criteria and D-dimer blood testing combined with Emergency department bedside ultrasound.
