Impact of Venotrain UlcerteC Venous Compression Device in the Treatment of Venous Ulcers in Daily Practice

The cornerstone of the management of venous leg or predominantly venous leg ulcers with IPS> 0.8 is venous compression as recommended by the HAS in June 2006. There is ample clinical evidence to support its importance to improve the chances of closure of this chronic lesion and shorten the healing time compared to the absence of compression. In 2016, a system of re-usable compression stockings (Venotrain® Ulcertec, BAUERFEIND, France), and bringing an interface pressure of 30...

Chronic and Acute Effects of Smoking on the Left and Right Ventricular Relaxation in Young Healthy Smokers

Impairment of relaxation, the early phase of ventricular diastole is the first stage of heart diastolic dysfunction. Left ventricular diastolic function can be determined noninvasively by Echo- Doppler – derived mitral valve flow velocities. The addition of pulmonary venous flow pattern enables more accurate assessment of left ventricle diastolic function. The role of the right ventricle in haemodynamic function of the heart is now emphasized. The right ventricle diastolic f...

Comparison of Hyperemic Efficacy Between Central and Peripheral Adenosine Infusion for Fractional Flow Reserve (FFR) Measurement

The purpose of this study is to evaluate the safety and effectiveness of the peripheral IV continuous infusion without the insertion of central venous vascular access method in the achievement of steady-state maximal coronary hyperemia compared with the central IV continuous infusion method.

Surfacer System to Facilitate Access in Venous Occlusions

Prospective, single-arm, multicentre, international Registry of the Surfacer System for the treatment of patients with limited or diminishing upper body venous access or pathology impeding standard access methods.The purpose of this post-market Registry is to assess the standard of care and clinical outcomes of the Surfacer System used in clinical routine according to the approved commercial indications.

Venous Congestion and Acute Renal Failure in Cardiac Surgery Postoperative

Acute renal failure (ARF) is a frequent complication in the postoperative cardiac surgery, and is a major risk factor for mortality in this context. The right ventricular dysfunction post cardiopulmonary bypass (CPB) is also a common complication, close to 100% if one takes into account the transient dysfunction. A recent study showed that right ventricular dysfunction and the IRA seemed related, rather on the slope of venous congestion. We wish to study this phenomenon more ...

Haemodynamics Variations of Transcutaneous Oxygen in Patient With Areterio-venous Leg Ulcers Under Venous Compression

Arterio-venous leg ulcers are real problems when it comes to public health because they have a major cost and they lead to social and Professional handicap. The management of these leg ulcers is not clear and can be venous compression or surgery. The aim of our study is to evaluate the variation of the transcutaneous oxygen with compression. The second aim is to see how tolerate is the compression and the quality of life.

Perforator Vein Injection for Symptomatic Venous Disease

The primary objective of this study is to compare two treatment strategies for symptomatic venous stasis disease with and without venous ulcer. These treatments are compression therapy alone vs. sclerotherapy of refluxing perforating veins with compression.

Peripherally Inserted Central Catheter Use for Dobutamine Infusion in Heart Failure Patients

In decompensation of heart failure, it may occur low cardiac output. For patients in this situation, the use of inotropic may be necessary. Prolonged intravenous infusion of inotropic agents can lead to phlebitis in peripherally venous access. On the other hand, central venous access presents complications inherent in the procedure. The peripherally inserted central catheter (PICC) may be an option in this situation. The present research project is a randomized clinical trial t...

Continuous Monitoring of Right Ventricular Function, Based on the Correlation Between the C-X Segment of the Central Venous Pressure Curve, and the Echocardiographic Evaluation of Right Ventricular Systolic Function

Close analysis of right ventricular function is still not done by all clinicians, even though it is indispensable; notably in cardiovascular ICUs. Right ventricular dysfunction is responsible for increased morbidity and marks a turning point in the patient's prognosis. It is difficult to analyse, and is principally assessed using echocardiography and by measuring the peak of the S' wave with pulsed Doppler and by measuring the tricuspid annular plane systolic excursion ...

Jugular Venous Flow Neurosurgical Patients

Our hypothesis is that there will be a decrease in internal jugular venous flow in the park bench position when compared to the supine position. There will also be a change in blood flow between the right and left internal jugular veins in the park bench position. In particular, there will be a greater reduction of flow on the dependent side. However, the internal jugular venous flow will be the same in both the prone and supine positions.

Jugular Venous Flow Healthy Volunteers

Our hypothesis is that there will be a decrease in internal jugular venous flow in the park bench position when compared to the supine position. There will also be a change in blood flow in the between right and left internal jugular veins in park bench position, particularly there will be a greater reduction of flow on the dependent side. However, the internal jugular venous flow will be the same in both the prone and supine position.
