Visualisation on blood flow mechanism of vein in deep vein thrombosis (DVT) study
… at the earliest stage of Deep Vein Thrombosis (DVT), this study aims to assess the velocity and vorticity at the valve region using the Computational Fluid Dynamics (CFD) method. The velocity ofblood and the size of valve orifice are considered important parameters in designing the vein. …

Advancing clinical practice in the management of Deep Vein Thrombosis: development, application and evaluation of the Autar DVT scale
Deep Vein Thrombosis (DVT) is a disease of hospitalised patients and is a precursor of Pulmonary Embolism (PE), a potentially fatal complication. DVT and PE are preventable and venous thromboprophylaxis consensus groups recommend that patients be risk assessed and accordingly receive appropriate …

The prevalence of deep vein thrombosis and associated factors in adult medical patients admitted to the University Teaching Hospital,Lusaka,Zambia
Deep vein thrombosis (DVT) and pulmonary embolism (PE) collectively referred to as venous thromboembolism (VTE) are a global concern with substantial morbidity and mortality. Symptomatic DVT commonly occur in hospitalized patients with acute medical illnesses. Thromboprophylaxis for DVT is not …

The Effect of Diet and Vitamin Manipulation on Communication in Autism: a Case Study
… therapy (SLT), and no diet/vitamin therapy (DVT) ; (b) Condition II, SLT only; (c) Condition III, both SLT and DVT; and (d) Condition IV, DVT only. Support for SLT was demonstrated. Support for DVT, however, was not exhibitied. Limitations of this study, anecdotal reports in support of DVT, …

Duration of oral anticoagulation in first-episode idiopathic deep vein thrombosis: A Markov decision analysis.
Deep venous thrombosis (DVT) of the lower extremity is a serious illness with an estimated incidence of 1 per 1000 persons per year. Objectives. To compare the lifetime risks and benefits of three months, six months, twelve months, two years, and lifelong anticoagulation for first episode …

Venous Thrombosis: Formation, Evolution And Resolution Imaging Using Non-Invasive MRI Techniques
Deep venous thrombosis (DVT) remains a major health problem. Although thrombolytic therapies are effective in recanalising the veins, restoring blood flow, preventing pulmonary embolism and post-thrombotic complications, there is still no consensus on the selection criteria for this invasive …

Aspiration Thrombectomy as the Sole Treatment for Acute and Sub-acute Deep Venous Thrombosis (DVT) of the Lower Extremity: mid and long-term clinical results
… 108 patients with acute and sub-acute DVT of the lower-extremity underwent aspiration thrombectomy with 9-10 guiding catheters, after insertion of a temporary inferior vena cava (IVC) filter. The inclusion criteria were patients with acute or sub-acute iliofemoral or femoropopliteal DVT …

Superconductivity and low temperature properties of niobium diselenide single crystals grown by direct vapor transport
… of 2H-NbSe₂ by a direct vapor transport (DVT) method was developed. Single crystal growth rate and the degree of crystal perfection were studied as deviations from stoichiometry were made over the compositional range of Nb<sub>0.95</sub>Se₂ to Nb<sub>1.05</sub>Se₂. Single crystal …

Risk factors for deep vein thrombosis in a South African public hospital
… suggests an association between HIV, TB and DVT. There are no studies of this link in the Southern African setting, where the incidence of both of these conditions (HIV and TB) is high. We therefore undertook a study to define the incidence of HIV and TB in patients with confirmed DVT in this …

Prevalence of acute deep vein thrombosis in HIV seropositive orthopaedic patients after major surgery at the University teaching hospital, Lusaka.
… are known risk factors in the development of DVT after major orthopaedic surgery. However, the added effect of HIV to major orthopaedic surgery in developing DVT is unknown. In addition the benefits of D-dimer screening of patients after major surgery is not emphasized. A total of 42 Patients, …

System for vessel characterization : development and evaluation with application to deep vein thrombosis diagnosis
… aimed at detecting deep vein thrombosis (DVT) in the lower limbs has been developed and evaluated using ultrasound image processing, location and force sensors measurements, blood flow information and a protocol based on the current clinical standard, compression ultrasound. The goal is to …

A Minimally Invasive Ultrasound Therapy Based On Time- Reversal Acoustics For The Treatment Of Deep Vein Thrombosis
… breaks away and blocks the arteries of lungs. DVT affects about 600,000 people in United States and causes approximately 300,000 deaths per year. Traditional DVT treatments have relied on using anticoagulants to prevent the recurrence of DVT but not in its treatment. Here we have developed a …

VENOUS THROMBOEMBOLISM IN SOUTHERN SWEDEN EPIDEMIOLOGY AND RISK FACTORS
… incidences of VTE (deep venous thrombosis [DVT] and pulmonary embolism [PE]) vary from 71 to 192 per 100,000 individuals per year. Incidences of DVT and PE have been estimated to 48-160 and 23-60 cases per 100,000 inhabitants per year, respectively. The aims of this thesis were to evaluate …

Non-invasive early diagnosis of deep vein thrombosis
Deep Vein Thrombosis (DVT) is a blood clot that forms in deep veins which commonly occur in lower limb or thigh. The blood clot blocks deep vein and can travel to lung and block pulmonary arteries. This condition will cause fatal Pulmonary Embolism (PE). DVT can be diagnosed using non-invasive …
