Abnormal sounds may resemble a musical wind instrument or >> Read More ...

Most cases of an occluded artery are due to atherosclerosis, where the formation of plaques narrow the lumen of the vessel. Surgery is considered if the occlusion is severe or if other measures like conservative management and medication fails to provide significant results as discussed under Arterial Occlusion Treatment. >> Read More ...
Arterial occlusion is the blockage of the blood vessel that carries oxygenated blood (artery) to different parts of the body. The occlusion obstructs blood flow either completely or partially thereby starving the tissues of oxygen. A partial obstruction may lead to atrophy (shrinking) or cell injury, which is either >> Read More ...

Blockage within an artery (occlusion) may arise for a number of reasons that are outlined in narrowing artery. The most common causes are atherosclerosis and a thrombus or embolus. Often the formation of atheromatous plaque causes a partial blockage and is then followed by the formation of a thrombus (blood clot) at the >> Read More ...
Thickening of a blood vessel may occur for a number of reasons. It is usually a result of changes within the vessel wall causing it to become thicker than normal. Alternatively it may arise from an enlargement of the vessel as a whole due to dilatation or birth defects. Thickening of the wall may affect only one part of an >> Read More ...
