Surgical management of deep venous reflux
Seminars in Vascular Surgery, 2002Axial deep venous reflux can be found in the majority of extremities with advanced skin changes and ulceration. It frequently is associated with recurrent disease and tends to progress with time. More than 30 years' experience with deep venous reconstructive surgery, as well as recent advances in diagnostic imaging, makes possible the rational use of ...

American Heart Journal, 1973
Abstract A loud systolic “clicky” sound may often be heard and recorded over the jugular veins in cases of tricuspid regurgitation. It occurred 0.12 second to 0.22 second after the onset of the QRS complex in the cases we studied. It is thought to be due to the sudden tensing of the neck veins caused by the regurgitant wave in cases of tricuspid ...

Evaluation of Methods for Detecting Venous Reflux
Archives of Surgery, 1990Using 793 limbs with nonobstructive venous reflux, we evaluated a number of techniques used for the assessment of venous reflux. The venous Doppler examination was found to be a reliable screening tool with excellent sensitivity and good specificity.

Thrombosis and Haemostasis, 1997
SummaryDuplex ultrasonography was used to measure the diameters of the common femoral, superficial femoral and popliteal vein segments in 123 patients following DVT. A cross sectional analysis was done based on the most recent visit to determine chronic venous diameter changes following DVT.Venous diameters in recanalized segments were smaller at all ...

Jugular diameter and venous reflux.
Annali italiani di chirurgia, 2016Aims of this study were to investigate the prevalence of reflux on internal jugular veins(IJV) by Valsalva maneuver and to define the association between reflux of IJV in subjects with both CCSVI and MS.We recruited 393 patients with MS and CCSVI. Study participants underwent EchoColor Doppler exam in order to define IJV diameter at confluence in ...

Telangiectasia and venous reflux in the Edinburgh Vein Study
Phlebology: The Journal of Venous Disease, 2011Objective The purpose of this study was to correlate the clinical findings in the Edinburgh Vein Study with the results of duplex scanning of the deep and superficial venous systems. Methods An age-stratified random sample of 1566 people (699 men and 867 women) aged 16–64 were selected from computerized age–sex registers of participating practices ...

Influence of Respiratory Maneuvers on Jugular Venous Reflux
Clinical Nuclear Medicine, 1981The cause of jugular venous reflux during a radionuclide cerebral angiogram is uncertain. The authors describe a patient in whom physiologic respiratory maneuvers had a profound influence on the jugular venous reflux during cerebral radionuclide angiography. The massive jugular reflux was abolished by intravenous injection of a radiotracer bolus during

Laser Ablation for Venous Reflux
2017Endovenous laser ablation (EVLA) has revolutionized the treatment of chronic venous insufficiency secondary to superficial venous reflux. It is one of the endothermal ablation techniques that has supplanted the open surgical ligation and stripping of the saphenous vein. Over the years, there has been an evolution in EVLA technology as well as technique.

Pathogenesis of leukoaraiosis: Role of jugular venous reflux
Medical Hypotheses, 2010Leukoaraiosis (LA) is a major cause of vascular dementia and disability in the elderly. Age and hypertension are the most two important risk factors. Despite its clinical significance, the etiology is so far unclear. Chronic cerebral hypoperfusion associated with vasogenic edema, microbleeding or/and endothelial dysfunction found in LA favors venous ...

Chronic venous insufficiency (CVI) encompasses an extensive range of clinical manifestations from limb swelling to non-healing ulcers. Etiologies for CVI in the deep venous system include reflux, venous obstruction, or a combination of the two. Of these, reflux alone or in combination with obstruction is the contributing factor in the overwhelming ...
