Filter by:Classic ballet dance is a demonstration of complex motor skills to be revealed in aesthetic combinations and repetitively, and it demands intensive use of the lower extremities within extreme of range of motion (ROM). Because ballet practice depends on advanced technical skills, it involves intensive physical training and causes an overload on the musculoskeletal system and foot deformities such as pes planus. Plantar venous pump (PVP) is a network of multiple venous vessels located between the muscles of the foot arch. PVP is considered the first step of venous return and discharges into the posterior tibial vein (PTV). PVP is reported to be active during gait while it is inactive in resting position. There are different views on the mechanisms enabling its activation 1-3. The general view is that during the stance phase of the gait, the flattening of the plantar arch with weight transfer causes the veins in this region to narrow and creates a force that pumps the blood up. The aim of this study is the investigation what kind of hemodynamic changes ballet training causes in the lower extremity
In venous ulcer, venous insufficiency is accompanied by lymphatic insufficiency. Manual lymphatic drainage (mld) technique cause to increase contraction rate of lymphatic collector and venous flow. It is known that Manual lymphatic drainage accelerates microcirculation, enabling nutrients and oxygen to reach tissues and at the same time removing residual substances from the tissue. We hypothesis that if we inrease to lypmhatic activity with MLD, we could stimulate healing of ulcer. The aim of this study to investigate the effect of manual lymphatic drainage on venous ulcer healing.
A feasibility study conducted in patients with incompetent (i.e. refluxing) perforator veins were treated using the Venclose RF Ablation System.
Validation of a new short Swedish patient reported outcome measure for superficial venous insufficiency. Analysis of its capacity to measure quality of life and its responsiveness to change caused by treatment.
With this prospective controlled trial, we hope to obtain more information about the coexistence between venous insufficiency and nocturia. In our opinion, venous insufficiency (CEAP 2-3a) leads to an increase in fluid accumulation in the lower limbs due to moving around all day. When laying down during nighttime, this fluid is reabsorbed into the systimic fluid pool, leading to an increase in diuresis and thus an increase in nocturnal voiding. Aim of this study is observe difference in nocturnal frequency and urine production before and after surgical treatment of venous insufficiency.
This is a prospective, non-randomized study in which patients who meet eligibility criteria and consent to participate will undergo a minimally invasive procedure using radiofrequency (RF) energy for ablation of the great saphenous vein (GSV).
Endothelial dysfunction is assessed in patients with chronic venous insufficiency of lower limbs (grade C4 according to C - clinical manifestations, E - etiologic factors, A - anatomic distribution of disease, and P - underlying pathophysiologic findings (CEAP) classification) prior to and after endovenous surgical procedure, i.e. endovenous laser ablation of great saphenous vein, microphlebectomy of varicose branches. Two treatment groups (with and without additional pharmacotherapy) are compared.
This study is a retrospective, chart review of treatment of patients with symptomatic varicose veins. Treated limbs must have the Great Saphenous Vein and/or Small Saphenous Vein treated with either cyanoacrylate closure (VenaSeal) or Endothermal Ablation (either Radiofrequency Ablation or Endovenous Laser Ablation).
Nocturia, or waking during the night to pass urine, is a multifactorial disease. An important cause of nocturia are peripheral edema due to accumulation of fluid in the lower limbs. Venous insufficiency is an important cause of peripheral edema. The investigators hypothesize that, as a result of the lying position during the night, the accumulated fluid in the lower limbs returns to the systemical circulation leading and is excreted during nighttime. This will lead to a higher voiding frequency during the night. With this trail the investigators wanst to prove the difference in leg edema between healthy volunteers and volunteers with venous insufficiency (Type 1 or 2).
This study is designed to find prevalence and risk factors for chronic venous disease (CVD) in the general population. All the resident, who live in a single rural settlement will be invited to participate.
