Platelet survival time (autologous labeling with 51chromium) was measured in 63 patients in order to evaluate the role of platelets in the thromboembolic complications of patients with hypoxemia and pulmonary hypertension. Thirty-eight of these patients had chronic obstructive airways disease; 13, primary pulmonary hypertension; seven, recurrent pulmonary embolism; four, the Eisenmenger syndrom...

A 28-year-old man presented with transient speech disturbance and right hemiplegia. Computed tomography of the brain revealed a low-density area in the right cerebellum. A ventilation/perfusion lung scintiscan detected multiple perfusion defects in the both lungs and catheterization revealed pulmonary hypertension. Venography of the upper extremities revealed obstruction of the left subclavian ...

Context: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as a novel virus infection, was first detected in China 2019 and has quickly spread pandemic leading to high mortality rate unprecedented challenges for healthcare systems. Although the SARS-CoV-2 clinical spectrum is different, failure of function coagulopathy common manifestation can be observed cases with severe disease (...

Peripheral blood hypereosinophilia reflects various underlying disorders. However, its thromboembolic consequences are not often highlighted. We report a case of acute pulmonary embolism in a 42 year-old male prisoner hospitalized for erythrodermic psoriasis who presented with generalized edema and shortness of breath. Severe eosinophilia (absolute eosinophil count 6232/ΜL) was also noted. Alth...

The thromboembolic complications of nephrotic syndrome are reasonably common, including spontaneous peripheral venous and/or arterial, pulmonary arterial, and renal venous occlusions. However, in comparison to the relatively high incidence of the venous thromboembolic complications with hypercoagulable status, arterial thromboses have been reported much less and it was only 20 cases in the Engl...

Combined oral contraceptives (Ocs) are the most commonly used androgen suppressors and the treatment of choice for menstrual dysfunction in women with polycystic ovarian syndrome (PCOs). Although OCs have remained popular due to their convenience and effectiveness, there have been continuing concerns about adverse effects. The OCs have long been known to incur and increased risk of venous throm...

Rivaroxaban (Xarelto) is a novel, oral, direct Factor Xa (FXa) inhibitor in late-stage development for the prevention and treatment of thromboembolic disorders. Rivaroxaban inhibits clot-associated and free FXa activity, and prothrombinase activity, and reduces thrombin generation. In animal models, rivaroxaban prevented venous and arterial thrombosis, and was effective at treating venous throm...
