What is a vein occlusion?
The vein occlusion occurs when the vein is blocked, clogged or too narrow so that the blood can easily flow. As a result, deoxygenated blood cannot return to the heart to continue normal circulation. Blood can back up in vein and cause swelling, pain and dysfunction in nearby organs and tissues. The most common place of the vein occlusion is the retina of the eye, but possibly any vein in the body can be affected. Treatment depends on the location and severity of obstruction, but common techniques include the use of drugs and undergoing surgery.
Many different factors can increase the risk of a person from the development of vein occlusion. The main risk factor is atherosclerosis, a condition that causes cholesterol to build and harden in blood vessels. People who have diabetes, high blood pressure, poor diet and sedentary lifestyle are generally more susceptible to atherosclerosis and occlusion in arteries and veins. Glaucoma significantly increases the risk of retinal vein occlusion. In addition, some people are genetically nOshy for disorders of blood clotting and problems with circulation.
When a blood clot or other obstacle blocks the vein, the blood begins to circulate backwards. It repeats tissues and organs, which can lead to a number of symptoms. For example, the vein occlusion in the ankle can cause the joint to increase rapidly, becoming tender and blue. Obeling vein can cause blurred or distorted vision that deteriorates within hours or days. It is important to see a doctor when unusual symptoms arise in order to perform the correct tests.
The physician may usually detect an occlusion of the vein by assessing symptoms and performing a specialized X -ray procedure. The fluorescent dye is injected into a vein in the arm and left to enter the circulation. X -ray rays are taken to monitor the dye for a place of suspected occlusion. If the dye does not flow through the place quickly or turns its course, it can be done with a confident diagnOsu.
anticoagulant drugs such as warfarin and heparin may be served intravenously to help disassemble the blood clots in the veins. If cholesterol is responsible for the symptoms, drugs may be prescribed to reduce blood pressure and the extension of the vein. Surgery may be required to remove or repair a vein. The stent may be permanently fastened to the blood vessel to open. The retinal occlusion is commonly treated with laser therapy to destroy the damaged veins.
