We designed a simple and integrated diagnostic algorithm for acute pulmonary embolism (PE). Diagnosis was based on clinical probability assessment, plasma D-dimer testing, then sequential testing to include lower limb venous compression ultrasonography, ventilation perfusion lung scan, and chest multidetector CT (MDCT) imaging. We included 321 consecutive patients presenting at ...

Microparticles (MPs) carrying active tissue factor (TF) have been detected in the plasma of cancer patients in particular in those presenting with acute deep vein thrombosis (DVT) or pulmonary embolism (PE). Experimental studies in mice have revealed that circulating MPs carrying TF contribute to thrombus formation. To study whether unselected ...

D-dimers are used in conjunction with clinical probability scores in the assessment of venous thromboembolism (VTE), and they are elevated in other conditions, including malignancy, infection and arrhythmias. High levels of D-dimers in VTE are associated with adverse outcomes, including increased mortality. Their significance in patients without VTE has not ...

OBJECTIVE: Behçet disease (BD) is a vasculitis of unknown etiology, characterized by oral or genital aphtosis and uveitis. Homocysteine (hcy) is an independent risk factor for venous and arterial thrombosis. The association between hyperhomocysteinemia and thrombosis has been investigated in some studies in BD patients. However, information on this association ...

INTRODUCTION: Chronic thromboembolic pulmonary hypertension (CTEPH) is a life threatening but often, by pulmonary endarterectomy, curable disease. The incidence of CTEPH after an acute pulmonary embolism (PE) appears to be much higher than previously thought. Systematic follow-up of patients after PE might increase the number of diagnosed CTEPH patients. AIM: ...

BACKGROUND/AIMS: Different etiologies for transient global amnesia (TGA) have been proposed, such as venous flow abnormalities, spreading depression and migraine-related mechanisms like focal ischemia. Jugular vein valve incompetence (JVI) is commonly described in TGA patients, but its contributing role in TGA pathogenesis is still unknown. We investigated the possible relationship ...

We report four patients with chronic kidney disease undergoing haemodialysis therapy, which had exhausted conventional venous access (internal jugular, subclavian) and non-conventional access (axillary, innominate) in the upper hemithorax for haemodialysis. This was primarily due to thrombosis of these veins caused by previous catheterisation. These patients did not qualify for ...
