The introduction of thalassotherapy (seaweed wraps cold) into the standard drug therapy and elastic compression techniques increases the effectiveness of conservative treatment of the patients presenting with chronic venous insufficiency due to the influence of biologically active components of
Chronic venous insufficiency (CVI) is inseparably linked to elevated venous pressure and is accompanied by vascular, dermal, and subcutaneous tissue damage and restructuring. Abundant evidence exists both in humans and in experimental models to suggest that the tissue damage may be initiated by
Pericapillary fibrin cuffs have been shown in patients with chronic venous insufficiency. It has been suggested that this fibrin deposition is responsible for an oxygen diffusion block, leading to local hypoxia and resulting in ulceration. Fibrinolysis is depressed in patients with venous
Tissue anoxia has for long been invoked as a cause of venous leg ulcers, and recently it has been suggested that pericapillary fibrin prevents the diffusion of oxygen in the skin. In the present study direct measurements of skin oxygen levels on the lower leg were made using a transcutaneous oxygen
In intrauterine growth restriction (IUGR), a subset of pregnancies undergoes placental vascular dysregulation resulting in restricted blood flow and fetal hypoxemia. Altered transcription of hypoxic regulated plasminogen activator inhibitor 1 (PAI-1) has been associated with pregnancy complications
BACKGROUND
Several studies have reported hypoperfusion of the brain parenchyma in multiple sclerosis (MS) patients. We hypothesized a possible relationship between abnormal perfusion in MS and hampered venous outflow at the extracranial level, a condition possibly associated with MS and known as
The basis for the new procedure is the simultaneous transcutaneous measurement of the peri-ulceral oxygen partial pressure (tcPO(2)), using a minimum of 4 electrodes which are placed as close to the wound margin as possible, additionally, as a challenge the patient inhales pure oxygen for
Data obtained from transcutaneously measured PO2 (tcPO2) were taken as an indication for a decreased oxygen supply to the skin in patients with chronic venous insufficiency III. Direct (invasive) measurements in LDS have not yet been performed. We therefore measured the intracutaneous PO2 (icPO2) in
According to the valve cusp hypoxia hypothesis (VCHH), deep venous thrombosis is caused by sustained non-pulsatile (streamline) venous blood flow. This leads to hypoxemia in the valve pockets; hypoxic injury to the inner (parietalis) endothelium of the cusp leaflets activates the elk-1/egr-1
It has been a long-term goal to develop non-invasive methods that can detect critical levels of tissue hypoxia to help in the management of chronic lower limb ischaemia. In the present study, skeletal muscle oxygenation was measured using a new Clark-type TCPO2 [transcutaneous PO2 (partial pressure
Initially, the progression of chronic venous insufficiency is related to venous hypertension. The earliest complaints or symptoms, as well as vessel wall deterioration, valve restructuring, and, eventually, varicose veins, result not only from elevation of pressure, but also from a cascade of
This study was performed to evaluate the effects of Ginkor Fort, a venotropic drug composed of Ginkgo biloba extract, troxerutine, and heptaminol, on neutrophil adherence to the endothelium of saphenous veins. When saphenous veins were incubated 2 h in hypoxic conditions, they showed a five- to
BACKGROUND
Ruscus aculeatus extract and the flavonoid hesperidin methylchalcone (HMC) are drugs used in the treatment of chronic venous insufficiency.
METHODS
In the present study, we investigated their effects on the activation of endothelial cells by hypoxia, a condition which mimics venous blood
1. A clinically available mixture of hydroxyethylrutosides (HR) was examined as inhibitors of endothelial cell activation by hypoxia in vitro. Thus, the effects of HR on ATP depletion, phospholipase A2 activation and neutrophil adherence were investigated in hypoxia-activated human umbilical vein
OBJECTIVE
The real mechanism for the development of the later stages of chronic venous insufficiency still remains unclear. Venous hypervolemia and microvascular ischemia have been reported to be the consequences of venous insufficiency. The aim of this study was to investigate the effects of
