Journal ArticleDOI
Plasma D-dimers in the diagnosis of venous thromboembolism.
TL;DR: Clinical management studies are clarifying the role of D-ds in the diagnostic paradigm of VTE: negative ultrasound and D-d findings obviate the need for serial imaging in suspected deep vein thrombosis, and anticoagulant therapy can be safely withheld in patients with non-high clinical suspicion for pulmonary embolism and non- high probability ventilation perfusion scan if D- d test results are negative.
Journal ArticleDOI
Venous Thromboembolism After Acute Stroke
TL;DR: Research into a strategy of screening for subclinical VTE in patients is needed, with a view to identifying a subgroup at risk of progression to symptomatic and life-threatening events, in whom outcome might be improved by anticoagulation.
Journal ArticleDOI
Venous thromboembolism after acute ischemic stroke - A prospective study using magnetic resonance direct thrombus imaging
TL;DR: Patients with Barthel indices of ≤9 or nonambulatory status 2 days after stroke are identified as a subgroup of acute ischemic stroke patients at very high risk for VTE in whom the current strategy of thromboprophylaxis may be inadequate.
Journal ArticleDOI
Dehydration and venous thromboembolism after acute stroke
James Kelly,Beverley J. Hunt,Roger R. Lewis,Ramasamyiyer Swaminathan,Alan R. Moody,Paul T. Seed,Anthony Rudd +6 more
TL;DR: Dehydration after AIS is strongly independently associated with VTE, reinforcing the importance of maintaining adequate hydration in these patients, and the relationship between biochemical indices of dehydration and VTE after acute ischaemic stroke is evaluated.
Journal ArticleDOI
Anticoagulation or Inferior Vena Cava Filter Placement for Patients With Primary Intracerebral Hemorrhage Developing Venous Thromboembolism
TL;DR: Treatment decisions continue to be made on an individualized basis and should include assimilation of information on key factors such as time elapsed post-stroke and lobar versus deep hemispheric location of the index event, natural history studies demonstrating a two-fold risk of recurrent intracerebral hemorrhage in the former subgroup.
