Colour Coded Duplex Ultrasound of Native Arterio-venous Fistula for Haemodialysis With Venous Pressure Measurement Using Controlled Compression Ultrasound as a Predictor for Shunt Maturation in the Early Postoperative Phase
Prospective observational ultrasound study of native arterio-venous fistula for haemodialysis with venous pressure measurement using controlled compression ultrasound.
Ultrasound may be useful for noninvasively determining the central venous pressure. We intend to compare the clinical examination of the neck veins; ultrasound delineation of the internal ...
Objectives: 1. To study the validity and reliability of estimation of the central venous pressure by measurement of internal jugular vein size using 2-dimensional ultrasound. ...
The main objective of this study is to obtain data to determine, in each individual with and without wearing compression stockings of different strengths and during different postures, the...
To evaluate the safety and effectiveness of the BlueLeaf System for the restoration of venous competence for the treatment of symptomatic chronic venous insufficiency (CVI).
The real mechanism for the development of the later stages of chronic venous insufficiency still remains unclear. Venous hypervolemia and microvascular ischemia have been reported to be the consequenc...
Venous leg ulcers are open lesions between the knee and the ankle joint, which occur in the presence of venous insufficiency. There are theories to explain the causes of venous insufficiency, which ul...
Venous disease is more common than peripheral arterial disease. Pathophysiologically, venous disease can be associated with obstruction, reflux, or both. A common feature in chronic venous disease is ...
Venous ulcers or stasis ulcers account for 80% of lower extremity ulcerations. Approximately 1-2% of the population will suffer from the chronic debilitating condition, with chronic venous insufficien...
To evaluate the performance of a closed-cell designed venous stent for the treatment of chronic ilio-femoral venous outflow obstruction (VOO) in the shortterm.
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
The blood pressure in the central large VEINS of the body. It is distinguished from peripheral venous pressure which occurs in an extremity.
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
A plant genus of the family HIPPOCASTANACEAE (or SAPINDACEAE by some) that contains antimicrobial protein 1 and escin. A. hippocastanum is used in folk medicine for treating chronic venous insufficiency.
Skin breakdown or ulceration caused by varicose veins in which there is too much hydrostatic pressure in the superficial venous system of the leg. Venous hypertension leads to increased pressure in the capillary bed, transudation of fluid and proteins into the interstitial space, altering blood flow and supply of nutrients to the skin and subcutaneous tissues, and eventual ulceration.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
