Etiology of varicose veins
Blood clotting within affected veins, termed superficial thrombophlebitis. These are frequently isolated to the superficial veins, but can extend into deep veins, becoming a more serious problem. Acute fat necrosis can occur, especially at the ankle of overweight people with varicose veins. Females are more frequently affected than males. Diagnosis edit Clinical test edit Clinical test that may be used include: Trendelenburg test to determine the site of venous reflux and the nature of the saphenofemoral junction Investigations edit further information: Ultrasonography of chronic insufficiency of the legs Traditionally, varicose veins were investigated using. This practice is not now widely accepted. People with varicose veins should now be investigated using lower limbs venous ultrasonography. The results from a randomised controlled trial on patients with and without routine ultrasound have shown a significant difference in recurrence rate and reoperation rate at 2 and 7 years of follow-up.
Minor injuries to the area may bleed more than normal or take a long time to heal. In some people the skin above the ankle may shrink ( lipodermatosclerosis ) because the fat underneath the skin becomes hard. Restless legs syndrome appears to be a common overlapping clinical syndrome in people with varicose veins and other chronic venous insufficiency. Whitened, irregular scar-like patches can appear at the ankles. This is known as atrophie blanche. Complications edit most varicose veins are reasonably benign, but severe varicosities can lead to major complications, due to the poor circulation through the affected limb. Pain, artrose tenderness, heaviness, inability to walk or stand for long hours, thus hindering work skin conditions / dermatitis which could predispose skin loss skin ulcers especially near the ankle, usually referred to as venous ulcers. Development of carcinoma or sarcoma in longstanding venous ulcers. Over 100 reported cases of malignant transformation have been reported at a rate reported.4. 7 severe bleeding from minor trauma, of particular concern in the elderly.
Varicose veins : causes, symptoms, and diagnosis
Varicose veins are distinguished from reticular veins (blue veins) and telangiectasias (spider veins which also involve valvular insufficiency, 6 by the size and location of the veins. Many patients who suffer with varicose veins seek out the assistance of physicians who specialize in vein care or peripheral vascular disease. These physicians include vascular surgeons, phlebologists or interventional radiologists. Contents, signs and symptoms edit Aching, heavy legs (often worse at night and after exercise). Appearance of spider veins ( telangiectasia ) in the affected leg. Ankle swelling, especially in the evening. A duizeligheid brownish-yellow shiny skin discoloration near the affected veins. Redness, dryness, and itchiness of areas of skin, termed stasis dermatitis or venous eczema, because of waste products building up in the leg. Cramps may develop especially when making a sudden move as standing.

In the United States and other countries in the world the most frequent causes of fatty liver are alcohol and drug abuse, obesity, diabetes, and sometimes chronic hepatitis. Drugs, skull, and a gravestone, buy this. Alkaline Phosphatase, alkaline phosphatase is an enzyme thats produced in the bile ducts, kidney, intestines, placenta and the bone. If this enzyme is high and alt and ast levels are pretty normal there could be a problem with the bile duct such as an obstruction. Some bone disorders may also cause alkaline phosphatase levels to increase. If there is an elevation of alkaline phosphatase it could also indicate there is an injury to the biliary cells. This could be due to gallstones or certain medications. Under normal circumstances the enzyme is mainly allocated to the bile, but if pathology exists the norm is disturbed and the enzyme increases in blood plasma. Gamma-Glutamyltranspeptidase, ggt is another enzyme thats produced in the bile ducts and can become elevated if there is a problem with the bile ducts.
Ct scan, Abdomen, liver 66 year Old Woman. Photographic Print, buy at m, onder its common for high levels of ast and alt in the liver to damage numerous liver cells, called hepatic necrosis and can lead to death of the cells. The higher the alt levels the greater the amount of cell death. Despite this alts arent always a borts good indicator of how well the liver is functioning. Only a liver biopsy can reveal this. Diseases that can cause increased levels of liver enzymes ast and alt are acute viral hepatitis a or b, as well as toxins caused by acetaminophen overdose, or a prolonged collapse of the circulatory system, which is called shock. It deprives the liver of fresh blood that brings oxygen and nutrients.
Transaminase levels can be 10 times the upper limit. Drug Store, art Print. Hopper, Edward, buy at m, sometimes elevated liver enzymes can be found in otherwise healthy individuals. In such cases theyre usually found to be twice the upper limit. Fatty liver is a common problem causing elevated liver enzymes.
Varicose veins - causes
There are enzymes that enter into the blood from the tissues to perform intracellular functions. Some of heiligbeen the enzymes are in the cell cytosol, such as alt, ast and ldh, and others are in the cell mitochondria, such as ggt and. Any damage to the liver will cause the enzymes from the cells to enter the blood and their activity will increase. Amounts of alt and ast are the greatest diagnostic value. In parenchymatous hepatitis serum transaminase alt increases, sometimes 100 times or more and ast to a lesser extent. In addition to the liver, ast enzymes can be found in the heart, muscle, brain and kidney and is released into blood serum when these tissues become damaged. For example, a heart attack or muscle disorders will increase ast serum levels. Because of this ast isnt necessarily an indicator of liver t is almost specifically found in the liver. After liver injury its released into the bloodstream and therefore can be used as a fairly specific indicator of liver function.

Together these enzymes are known as transaminases. Alkaline phosphatase (AP) and gammaglutamyl transferase (GGT) are known as cholestatic liver enzymes. If these enzymes are elevated it can indicate the presence of engels liver disease. Secretory enzymes are enzymes made in the liver and allocated to the blood plasma. Their role is physiological, for example, enzymes involved in blood clotting (AC globulin) or cholinesterase, which catalyzes the hydrolysis of acetylcholine. Damage to the liver will reduce their synthesis leading to a decrease in their enzyme activity. Cirrhosis liver Specimen, photographic Print, buy at m, ast and alt.
What are liver enzymes? Theyre proteins that help speed up a chemical reaction in the liver. Blood tests, called liver function tests, are used to evaluate various polyarthritis functions in the liver. Examples of these functions are metabolism, filtration and excretion and storage, which are often performed by liver enzymes. But not all liver function tests measure enzyme function. Liver enzymes are found in normal plasma and serum and can be divided into different groups. Aspartate aminotransferase (ast or sgot) and alanine aminotransferase (alt or sgpt).
What Are varicose leg veins?
3, non-surgical treatments include sclerotherapy, elastic stockings, leg elevation and exercise. The traditional surgical treatment has been vein stripping to remove the affected veins. Newer, less invasive treatments which seal the main leaking vein are available. Alternative techniques, such as ultrasound-guided foam sclerotherapy, radiofrequency ablation and endovenous laser treatment, are available as well. Because most of the blood gekneusd in the legs is returned by the deep veins, the superficial veins, which return only about 10 of the total blood of the legs, can usually be removed or ablated without serious harm. Secondary varicose veins are those developing as collateral pathways, typically after stenosis or occlusion of the deep veins, a common sequel of extensive deep venous thrombosis (DVT). Treatment options are usually support stockings, occasionally sclerotherapy and rarely, limited surgery.
blood from flowing backwards (retrograde flow or venous reflux). 2, leg muscles pump the veins to return blood to the heart (the skeletal-muscle pump against the effects of gravity. When veins become varicose, the leaflets of the valves no longer meet properly, and the valves do not work (valvular incompetence). This allows blood to flow backwards and they enlarge even more. Varicose veins are most common in the superficial veins of the legs, which are subject to high pressure when standing. Besides being a cosmetic problem, varicose veins can be painful, especially when standing. Severe long-standing varicose veins can lead to leg swelling, venous eczema, skin thickening ( lipodermatosclerosis ) and ulceration. Although life-threatening complications are uncommon, varicose veins may be confused with deep vein thrombosis, which may be life-threatening.
