Active clinical trials for "Venous Insufficiency"

Chronic venous disease (CVD) is widespread in adult subjects of western countries and is responsible of important morbidity and healthcare costs. CVD has never been extensively studied in pediatric population where the early pathophysiological alterations may occur undetected. The aim of this study is to assess the prevalence of CVD searching also for the early clinical and instrumental signs of this disease.

Chronic venous insufficiency occurs when your leg veins don't allow blood to flow back up to your heart. Normally, the valves in your veins make sure that blood flows toward your heart. But when these valves don't work well, blood can also flow backwards. This can cause blood to collect (pool) in the legs. Chronic venous disease is a highly prevalent condition in the general population, and it has a significant impact on quality of life. While it is usually manifested by obvious signs, such as varicose veins and venous ulcers, other symptoms of the disease are less specific. Among the other symptoms, which include heaviness, swelling, muscle cramps and restless legs, pain is the symptom that most frequently compels CVeD patients to seek medical aid. However, there is a substantial discrepancy between pain severity and clinically detectable signs of CVeD, questioned by several opposing studies. Further evaluation is needed to clarify this subject, and to analyse whether pain development predicts objective tool to evaluate pain by dosflexin exercise pre surgery and post and measure the severity of pain by heat stimulation . General management of CVeD starts with advising lifestyle . pain in chronic venous insufficiency it will measure before and after treatment by using contact heat evoked potential (CHEPS) and visual dialog scale ( VAS ) to estimate the pain intensity the severity of the pain before the patient do exercise before three moths of leaser endovenous ablation procedure . 2-photo-plethysomography Non invasive technique , pp sensor emit infrared light detects changes in reflection from epiderma layer . Vessels full of blood reflect 10 times less than without blood . On dorsiflexion - pressure drops, increasing reflection in the measuring window Venous assessment the venous refill time, is shorter and typically less than 20 s

The aim of this study is to evaluate the long-term effects of endovenous steam ablation (EVSA). Postoperative data at 3-4 year follow-up will be collected from patients treated with EVSA.

In this prospective, observational study, the investigators aim to investigate the symptoms of varicose vein patients.

The aim of this study is to report a collaborative, prospective Singaporean experience using the Endovenous Radio Frequency® (EVRF®) from F Care Systems (Belgian) for the treatment of primary great and short saphenous vein reflux.

In this proposal, the investigators seek to determine whether a reduced compression after endovenous ablation procedure in treating superficial venous insufficiency affects the outcomes. This study involves only the use of the compression stocking post endovenous ablation procedure and everything else is standard according to current guidelines. The investigators general strategy will be to determine the role of a minimal post-operative compression and the status of patient satisfaction including (1) Success closure rate of the treated vein. (2) Less pain; (3) Easier accepted by the patients.

We collected retrospectively the non contrast MRI in chia yi memorial hospital for different venous disease of lower extremity morphology and flow ananlysis were done.

Part I: Proof of concept trial to achieve normal venous pressure values under different provocation maneuvers in healthy persons Part II: Non invasive measurement of venous pressure under different provocation maneuvers in patients with chronic venous disease

To establish if there are venous obstructions in patients with neurodegenerative disorders
