Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
The exact cause of lipodermatosclerosis is unknown. [3] [6] Venous disease, such as venous incompetence, venous hypertension, and body mass may be relevant to the underlying pathogenesis. [3] Increased blood pressure in the veins (venous hypertension) can cause diffusion of substances, including fibrin, out of capillaries.
The most commonly affected vessels in peripheral vascular disease are the arteries supplying the legs, so when less blood gets to the muscle tissue in the legs, that tissue sees less oxygen and becomes ischemic. Ischemic cells release adenosine, a type of signaling molecule, which is thought to affect nerves in these areas, which is felt as pain.
This area may feel hard, warm, and tender. The skin around the vein may be itchy and swollen. The area may begin to throb or burn. Symptoms may be worse when the leg is lowered, especially when first getting out of bed in the morning. A low-grade fever may occur. Sometimes phlebitis may occur where a peripheral intravenous line was started.
A peripheral vascular examination is a medical examination to discover signs of pathology in the peripheral vascular system. It is performed as part of a physical examination , or when a patient presents with leg pain suggestive of a cardiovascular pathology.
It can cause the affected limb to swell, and cause pain and an overlying skin rash. In the worst case, a deep vein thrombosis can extend, or a part of a clot can break off as an embolus and lodge in a pulmonary artery in the lungs, known as a pulmonary embolism .The decision to treat deep vein thrombosis depends on its size, a person's symptoms ...
With PTS, these symptoms typically are worse after walking or standing for long periods of time and improve with resting or elevating the leg. [ 1 ] PTS lowers a person's quality of life after DVT, specifically with regards to physical and psychological symptoms and limitations in daily activities.
[1] Venous ulcers are wounds that are thought to occur due to improper functioning of venous valves, usually of the legs (hence leg ulcers). [2]: 846 They are an important cause of chronic wounds, affecting 1% of the population. [3] Venous ulcers develop mostly along the medial distal leg, and can be painful with negative effects on quality of ...
