OBJECTIVES We sought to determine the circadian, weekly, and seasonal variation of coronary stent thrombosis. BACKGROUND Other adverse cardiovascular events such as acute myocardial infarction are known to have higher incidences during the early morning hours, Mondays, and winter months. METHODS The Mayo Clinic Percutaneous Coronary Intervention Registry was searched for patients admitted t...

Cerebral venous sinus thrombosis with internal jugular vein thrombosis is not reported as a complication in nephrotic syndrome. We report a 40-year-old male with nephrotic syndrome, who had headache during his hospitalization. Conventional diagnostic tests showed extensive thrombosis at the proximal part of superior sagittal sinus, left cortical vein, left sigmoid-transverse sinus and left inte...

BACKGROUND Cerebral venous sinus thrombosis is rare and can be promoted by various conditions. We report the case of cerebral venous thrombosis in a patient using androgens. CASE DESCRIPTION A 31-year-old man using androgens for bodybuilding was admitted for headache and vomiting. He had cerebral venous sinus thrombosis, but extensive examinations did not reveal any known cause. CONCLUSIONS...

Superior vena cava (SVC) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC synd...

Objectives: Venous thromboembolis is a clinical condition that often occurs from deep vein thrombosis of lower extremity. The incidence of deep venous thrombosis in the etiology of pulmonary thromboembolism may be as high as 90%. Doppler ultrasonography of lower extremities is recommended generally to determinate the etiology of pulmonary thromboembolism. The aim of this study is to present the...

Introduction: In patients with essential thrombocythemia (ET), the vascular complications contribute to morbidity and mortality. To better predict the occurrence of thrombotic events, an International Prognostic Score for Thrombosis in Essential Thrombocythemia (IPSET-thrombosis) has recently been proposed. We present the application of this score and compare its results with the usual classifi...

OBJECTIVES To evaluate the impact of preoperative sepsis on risk of postoperative arterial and venous thromboses. DESIGN Prospective cohort study using the National Surgical Quality Improvement Program database of the American College of Surgeons (ACS-NSQIP). SETTING Inpatient and outpatient procedures in 374 hospitals of all types across the United States, 2005-12. PARTICIPANTS 2,305,380...

BACKGROUND In about a third of patients with venous thromboembolism, the cause of the disorder is unexplained. In patients with atherosclerosis, activation of both platelets and blood coagulation and an increase in fibrin turnover are detectable, which may lead to thrombotic complications. Whether atherosclerosis is associated with an increased risk of venous thrombosis is unknown. METHODS We...

AIMS To investigate the efficacy and outcome of emergency percutaneous coronary interventions (PCI) in patients with stent thrombosis. METHODS AND RESULTS Between 1995 and 2003, 6058 patients underwent bare-metal stent implantation, of which 95 (1.6%) patients suffered from stent thrombosis. The timing of stent thrombosis was acute in 10 (11%), subacute in 61 (64%), and late in 24 (25%) patie...
