Upper extremity deep venous thrombosis (UEDVT) involves thrombosis of the deep veins of the arm as they enter the thorax. They are increasing in frequency, largely due to the rising use of central venous catheters and implantable cardiac devices, and represent more than 10% of all DVT cases, Upper extremity deep venous thrombosis has been historically misunderstood when compared to lower extrem...

Ambulatory or Day Hospital surgery is economically advantageous but requires care in patient selection, choice of anaesthesia, drug administration and discharge criteria. Locoregional anaesthesia is particularly suitable in the treatment of lower limb varicose veins since complete reversal of the anaesthetic block in a few hours in non-hospitalized patients is possible. Our experience over 18 m...

Introduction: To date, conventional venography remains the gold standard for morphologically assessing the veins of the lower extremities. The required administration of iodinated contrast is associated with complications including anaphylaxis, nephrotoxicity as well as venous thrombosis. MR-venography based on TOF techniques has thus been advocated as an attractive non-invasive alternative par...

We use the Hill function to analyze the dynamics of Tc-99m 2 methoxy-isobutyl-isonitrile (Tc-MIBI) scintigraphy data and to examine the earlier lower extremity microvascular perfusion of diabetic patients without typical clinical symptoms and with the preserved normal ankle-brachial index (ABI).Eighty-eight participants (30 healthy control, 34 diabetic patients, and 24 diabetic patients with pe...

OBJECTIVE Chronic cerebrospinal venous insufficiency (CCSVI) is characterized by combined stenoses of the principal pathways of extracranial venous drainage, including the internal jugular veins (IJVs) and the azygous (AZY) vein, with development of collateral circles and insufficient drainage shown by increased mean transit time in cerebral magnetic resonance (MR) perfusion studies. CCSVI is s...

When peripheral artery disease (PAD) affects the infrapopliteal vessels alone or in addition to the more proximal vessels, limb-threatening ischemia and tissue loss often occur. In the United States, between 150,000 and 300,000 cases of critical limb ischemia (CLI) are diagnosed each year.1 Within 1 year of diagnosis, 30% of CLI patients will have had a major amputation, and 25% will have died;...

Chronic venous insufficiency of the lower limbs is a disease which is caused by an increased blood pressure inside the veins of the leg and the resulting increase of the contained blood volume. This work focuses on developing a device which uses impedance plethysmography, also known as impedance phlebography, to obtain information about the blood volume in the lower leg and provides the possibi...

Chronic ulceration of the lower leg is a frequent condition, with a prevalence of 3-5% in the population over 65 years of age. The incidence of ulceration is rising as a result of the ageing population and increased risk factors for atherosclerotic occlusion such as smoking, obesity and diabetes. Ulcers can be defined as wounds with a 'full thickness depth' and a 'slow healing tendency'. In gen...
