Treatment goals for deep venous thrombosis include stopping clot propagation and preventing the recurrence of thrombus, the occurrence of pulmonary embolism, and the development of pulmonary hypertension, which can be a complication of multiple recurrent pulmonary emboli. About 30 percent of patients with deep venous thrombosis or pulmonary embolism have a thrombophilia. An extensive evaluation...

Symptoms of deep cerebral vein thrombosis (DCVT) are variable and nonspecific. Radiologic findings are essential for the diagnoses. In the majority of cases of deep internal cerebral venous thrombosis, the thalamus is affected bilaterally, and venous hypertension by thrombosis causes parenchymal edema or venous infarction and may sometimes cause venous hemorrhage. Intravenous injections of mann...

Radionuclide plethysmography (RPG) is a new technique that uses Tc-99m labelled red blood cells to ascertain changes in venous volumes by detecting the change in counts in response to the inflation and deflation of proximal thigh cuffs. Diagnosis of ileofemoral venous occlusion is possible using this technique, which also provides kinetic data of venous outflow. A range of normal values was def...

In patients presenting with clinically suspected deep vein thrombosis, symptomatic pulmonary embolism is rarely apparent. To assess the prevalence of silent pulmonary embolism in outpatients with proven deep vein thrombosis but without symptoms of pulmonary embolism, perfusion ventilation lung scans were performed in 101 consecutive patients at presentation. Fifty-one percent of these patients ...

OBJECTIVE Coagulation and inflammation are inter-related. Gas6 (growth arrest-specific 6) promotes venous thrombosis and participates to inflammation through endothelial-innate immune cell interactions. Innate immune cells can provide the initiating stimulus for venous thrombus development. We hypothesize that Gas6 promotes monocyte recruitment during venous thrombosis. APPROACH AND RESULTS D...

OBJECTIVE The purpose of this presentation is to review the techniques of performing an upper extremity Doppler examination, in addition to illustrating the sonographic appearances of acute and chronic upper extremity deep venous thrombosis (UEDVT). METHODS The risk factors and complications of UEDVT are discussed, and the anatomy of the upper extremity deep venous system as well as examinati...

In 539 consecutive stroke patients admitted to a rehabilitation department, we studied the possible role of atrial fibrillation as a risk factor for deep venous thrombosis and pulmonary embolism by analyzing a series of relevant clinical data in patients with and without atrial fibrillation and in patients with and without venous thromboembolic complications. Deep venous thrombosis as well as a...

OBJECTIVE to determine the incidence of deep vein thrombosis and prophylaxis quality in hospitalized patients undergoing vascular and orthopedic surgical procedures. METHODS we evaluated 296 patients, whose incidence of deep venous thrombosis was studied by vascular ultrasonography. Risk factors for venous thrombosis were stratified according the Caprini model. To assess the quality of prophy...

Objective: to determine the incidence of deep vein thrombosis and prophylaxis quality in hospitalized patients undergoing vascular and orthopedic surgical procedures. Methods: we evaluated 296 patients, whose incidence of deep venous thrombosis was studied by vascular ultrasonography. Risk factors for venous thrombosis were stratified according the Caprini model. To assess the quality of prophy...

In a prospective study of patients admitted to a coronary care unit, the incidence of isotopically diagnosed deep venous thrombosis was found to be related to the severity of illness rather than to the duration of bed rest. In addition, no negative correlation was found between cigarette smoking and deep venous thrombosis.
