Active clinical trials for "Lymphedema"

To approval for detecting lymphedema fibrosis before its progression, verification of CT-based quantification of suprafascial microscopic fibrosis has been tried.

Vascularized lymph node flap transfer (VLNT) was believed to be the treatment of choice for moderate-to-severe lymphedema. Recent publications have supported the use of supermicrosurgical lymphaticovenous anastomosis (LVA) for treating severe lymphedema. This study hypothesizes whether LVA can be performed on post-VLNT patients seeking further improvement.

The study is a cohort study of patients at the University Hospital during the first two days of intensive treatment. The patients are randomly divided into two groups (N=10). Throughout the study, group A is treated with the multilayer elastic bandage while group B is bandaged with contention only. The bandages were applied on the first and second day and were maintained in place. The bandages were applied on the first and second day and were maintained for 24 hours. All patients performed 30 minutes of physical activity in the bandage on both days. The evaluation is based on the volumetric difference, skin quality and quality of life of these patients

Many clinical situations in oncologic surgery imply the need to dissect more or less extensively lymph node stations which are in direct relation with the lymphatic drainage of the anatomical region affected by cancer. The dissected lymph nodes drain generally several regions, and their dissection reduces then the drainage capacity of all these regions, increasing the risk for the patient to develop a secondary lymphedema, shorter or longer after surgery. Efficient treatments exist, but are difficult to implement and to continue for a long time.The later the treatment of the lymphedema begins, the heavier it is, both on the medical and socio-economic level. The lymphofluoroscopy, shows that some oncologic patients, operated and free of apparent secondary lymphedema, present abnormalities of the lymphatic network. The present study aims to confirm that it is now possible to detect secondary lymphedema at a subclinical stage.

Volumetry is essential for the diagnosis and follow-up of patients with limb edema. The objective of this project is the validation of real-time reconstruction and calculation of limb volume using a 3D laser scanner. Water - displacement volumetry (water-filled boot) is the reference method with known accuracy and reproducibility, but is not commonly used in clinical practice because it is cumbersome, difficult, and time-consuming. The most commonly used method remains segmental limb perimetry with a tape measure, followed by volume calculation using the truncated cones formula, thus excluding de facts extremities (hands and feet) which can neither be likened to cones nor easily measured. Quantification limb volume and volume changes is essential for the diagnosis and follow-up of patients with chronic venous insufficiency or lymphedema, two very common pathological conditions. It is mandatory for the evaluation of therapeutic approaches. The present study will use an innovative technology of volume acquisition by freehand laser scanning with a hand-held camera with Quantification limb volume and volume changes is essential for the diagnosis and follow-up of patients with chronic venous insufficiency or lymphedema, two very common pathological conditions. It is mandatory for the evaluation of therapeutic approaches. The present study will use an innovative technology of volume acquisition by freehand laser scanning with a hand-held camera with real-time 3D reconstruction. Its advantages are non-contact, accurate and detailed quantification of edema, including extremities, allowing to assess the magnitude and topography of physiological, pathological, or treatment - induced volume changes. This approach will ultimately provide data that will used for designing personalized limb compression ortheses.

Lymphedema is one side effect of breast cancer treatment. Measuring the edematous limb enables monitoring changes in the lymphedema and the effect of treatment. Circumference measurement using a measuring tape is an inexpensive simple method and therefore useful and widespread in clinical practice. Circumference measurement performance varies amongst therapists and lacks uniformity in the literature. To date, the effect of different limb positions on measurement results has not been examined. Purpose: The purpose of this study is to describe 1) the effect of position on upper limb volume measurement by using circumference measurement and 2) to examine whether the difference between positions are similar in the upper limbs of the same woman, and 3) between groups of women who are in the intensive phase, in the maintenance phase of lymphedema treatment and women without lymphedema

This is an epidemiological cross-sectional study aiming to determine the prevalence of lymphedema and the incidence of risk factors in patients diagnosed with unilateral breast cancer in a cohort from 2008 to 2020 in a specialised oncology centre in Valle del Cauca, Colombia.

The aim of this study is to evaluate tissue changes via ultrasound after complex decongestive therapy.

The investigators will describe the expression of mutation CELSR1 with codon stop and amino acids substitution mechanism in primary lymphedema, in both clinical examination and imaging exploration

Breast cancer related lymphedema (BCRL) is the most common complication after breast cancer surgery, which brings a heavy psychological and spiritual burden to patients. For a long time, the diagnosis and treatment of lymphedema has been a difficult point in domestic and foreign research. To a large extent, it is because most of the patients who come to see a doctor have already developed obvious lymphedema, and the internal lymphatic vessels have undergone pathological remodeling[1] Therefore, it is particularly important to detect early lymphedema and intervene in time through the use of sensitive screening tools. Indocyanine green (ICG) lymphangiography is a relatively new method, which can display superficial lymph flow in real time and quickly, and will not be affected by radioactivity [7]. In 2007, indocyanine green lymphography was used for the first time to evaluate the function of superficial lymphatic vessels. In 2011, Japanese scholars found skin reflux signs based on ICG lymphography data of 20 patients with lymphedema after breast cancer surgery, and they were roughly divided into three types according to their severity: splash, star cluster, and diffuse (Figure 1) [8]. Later, in 2016, a prospective study involving 196 people affirmed the value of ICG lymphography in the early diagnosis of lymphedema, and made the images of ICG lymphography more specific stages 0-5 [9], but The staging is still based on the three types of skin reflux symptoms found in a small sample clinical study in 2011, which is not completely applicable in actual clinical applications. In addition, when abnormal skin reflux symptoms appear on ICG lymphangiography, the pathophysiological changes that occur in the body lack research and exploration. Therefore, this research hopes to refine the image features of ICG lymphography through machine learning (deep learning), and establish a PKUPH model for diagnosing early lymphedema by staging the image features.
