Available in PDF, EPUB and Kindle. Book excerpt: Venous valves rank among the smallest and most delicate organs of the human and animal bodies - so why devote an entire book to them? We were induced to do so by several reasons. First of all we would point out the clinical significance of venous valves. In the pathogenesis of a number of widespread diseases, such as varicose veins or the post-thrombotic syndrome, venous valves are involved as the underlying cause or at least a factor contributory to the symptoms. According to Taheri et al. these venous diseases occur ten times more frequently than arterial obliterations. Incompetence of venous valves also plays a causal role in varicocele, the most frequent cause of male infertility. But not only pathogenetic reasons induced us to write this book. In more recent times there has been a growing tendency to reconstruct functional valve disorders therapeutically; several surgical methods have been developed, which are critically reviewed in this book. It was our aim to sum up existing knowledge with respect to structure and function of venous valves and to expand that knowl edge by findings of our own. Examinations of semi-thin sections and unilayered en-face preparations have hardly been published so far, and systematic studies of the ultrastructure by electron-microscopy were not to be found in the literature. We are very grateful, therefore, to Dr. Silvana Geleff for having undertaken such a study upon our suggestion.

Available in PDF, EPUB and Kindle. Book excerpt: The 8th International Congress of Biorheology was held at the Pacifico Yokohama, Japan, a brand new, versatile convention center for international meetings, from August 3 through 8, 1992. There were many plenary lectures and symposia, one of which was entitled "Mechanics of the Venous System." It was at this symposium that we, the editors of this monograph, each presented papers. We then moved to Gifu, Japan, for the Gifu Workshop on Veins and Vascular Capacitance. This was held on August 9, 1992, with the Second Department of Medicine, Gifu University School of Medicine, serving as the host. Nine papers were presented in the oral sessions and there were five poster presentations. This monograph, which is intended to provide a bird's eye view of recent trends in studies of the venous system, is an outgrowth of the Gifu Workshop. While it is not exactly the Proceedings ofthat workshop, materials in the monograph were developed from ideas presented there.

Download or read book Venous Disease written by Charles V. Ruckley and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Varicose veins are a very common problem. The precise aetiology of primary varicose veins remains unclear. It seems likely from the available evidence that inherited structural weakness combined with haemodynamic or microcirculatory abnormalities eventually lead to reduced vein wall elasticity, dilatation and the formation of varicosities. Increasing age, female gender, parity and occupation may all promote the development of varicose veins in susceptible individuals. Further clinical and experimental studies are necessary if the relative contribution of each of these factors is to be fully elucidated. References 1. Editorial. The treatment of varicose veins.

Download or read book Design Analysis Testing and Evaluation of a Prosthetic Venous Valve written by Daniel Edward Tanner and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic Venous Insufficiency (CVI) is characterized by chronic venous hypertension from blood pooling in the lower limbs. The resulting symptoms include leg pain, varicose veins, fatigue, venous edema, skin pigmentation, inflammation, induration, and ulceration. Reflux from incompetent venous valves is a factor in up to 94% of individuals with CVI. Current treatments of CVI include compression stockings, drug therapy, vein disabling, venous stenting, and surgical correction with varying rates of success. However, a minimally invasive correction of deep venous reflux does not currently exist. A transcatheter prosthetic venous valve has the potential to be an effective, minimally invasive treatment for deep venous reflux which could treat up to 1.4 million individuals in the United States suffering from venous ulceration and make more than 1.7 billion dollars each year. Previously developed prosthetic venous valves have had problems with competency, patency, thrombogenicity, biocompatibility, and incorrect sizing. To meet the clinical need a prosthetic valve needs to be developed which succeeds where previous valves have failed. This thesis describes the design, analysis, pre-clinical testing, and evaluation of a novel prosthetic venous valve. Design specifications for an effective prosthetic venous valve were created. Verification tests were developed and performed which demonstrated that the valve met every design specification. Finite element and computational fluid dynamics simulations were performed to analyze the valve and calculated a maximum shear rate of 2300 s-1 in the valve during the high forward flow after a Valsalva maneuver. The valve is made of a biocompatible material that has low thrombogenicity, Poly(vinyl-alcohol) cryogel. On the average, the valve allows less than 0.5 mL/min of reflux at low and high retrograde pressures even after 500,000 cycles, indicating that it will reduce the reflux of individuals with venous reflux by more than 99.4%. The valve closes in less than 0.07 seconds and allows the distal pressure to rise to an average of 7% of the equilibrium pressure 30 seconds after a simulated ankle flexion. The valve increases the outflow resistance an average of 2.3 mmHg*min/L which is much less than obstruction levels, e"5 mmHg*min/L. The valve can fit in a 16 French catheter and is capable of percutaneous delivery. The base of the valve is 1.5 times the diameter of the vein in which it is to be implanted to help correct orientation upon deployment. Fluid behind the valve's leaflets is ejected with a forward flow rate of 400 mL/min, suggesting that thrombus formation will not occur at this location. A stented valve remained patent in a porcine blood flow loop for 3 hours. The valve remains competent without buckling in a constricted vein at rest. The valve can expand to fit a vein with a maximum diameter 1.4 times the valve's initial diameter with low risk of tearing or leaflet prolapse. An IACUC protocol for a 12 week study to test the valve in sheep was prepared and approved. A study to evaluate the valve in humans is proposed with endpoints that can be tested for statistical significance and compared with other treatments for CVI. A set of valves which will correct reflux in the majority of common femoral, femoral, and popliteal deep veins is proposed and a sizing guide for surgeons is provided. The minimum distance between prosthetic valves placed in the same vein segment is 13 cm. A comparison of this valve with previously developed prosthetic venous valves and recommendations for work to be performed in the future are given. The valve proposed in this work is the only valve to meet all design specification for an effective prosthetic venous valve, and therefore shows great potential to be a minimally invasive treatment for deep venous reflux.

Download or read book Understanding Venous Reflux the Cause of Varicose Veins and Venous Leg Ulcers written by Mark S. Whiteley and published by . This book was released on 2011 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost 1 in 2 people suffer from problems with leg veins - so if you don't have them then someone close to you will. Venous reflux (the major cause of leg vein problems) can cause tired or aching legs, swollen or itchy ankles. Many people suffering from venous reflux are unaware of the problem, until they develop unsightly varicose veins, thread veins, venous eczema or venous leg ulcers. Many doctors and nurses are not aware of the new information available and still treat their patients inappropriately with creams, bandages or support stockings. "Understanding Venous Reflux - the cause of varicose veins and leg ulcers" has been written by Mark Whiteley, an internationally renowned vein expert. With clear explanations, illustrated by over 50 easy-to-follow diagrams, this book makes the understanding of venous reflux - the underlying cause of varicose veins and most venous problems (such as thread veins, venous leg ulcers, venous eczema, discoloured ankles, etc.) - accessible to most readers, helping them decide on what treatment they should seek. For medical and nursing students, as well as all doctors, nurses and other health care workers who deal with legs and leg vein problems, this is an essential text.
