In this article, we explain what an arterial clot is, how it forms, the difference between thrombosis and embolism, symptoms, complications, treatment options, and prevention<a href=\"https:\/\/bisdasmd.gr\/en\/bio\/\">vascular surgeon Dr. Bisda<\/a> in modern treatment techniques.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>What is a clot?<\/strong><\/h2>\n<p>A clot is a mass of blood that forms through coagulation. Under normal conditions, clotting is essential for healing wounds. However, when a clot forms inside a blood vessel without injury, it can obstruct blood flow and cause serious harm.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>How do clots form in arteries?<\/strong><\/h2>\n<p>Arterial clot formation is linked to abnormal blood flow, injury to the vessel lining (endothelium), or increased tendency of the blood to clot. Key contributors include:<\/p>\n<ol>\n<li><strong>Atherosclerosis<\/strong>: lipid\/cholesterol build-up damages the arterial wall and promotes clot formation<\/li>\n<li><strong>Trauma or surgery<\/strong>: vessel injury increases clotting risk<\/li>\n<li><strong>Prolonged immobility:<\/strong>(in selected contexts)<\/li>\n<li><strong>Underlying conditions<\/strong>thrombophilia, malignancy, and cardiac arrhythmias increase risk<\/li>\n<\/ol>\n<p>&nbsp;<\/p>\n<h2><strong>Arterial thrombosis vs arterial embolism<\/strong><\/h2>\n<ul>\n<li><strong>Arterial thrombosis<\/strong>: a clot forms within an artery and remains at the site of formation, partially or completely blocking blood flow and causing ischaemia.<\/li>\n<li><strong>Arterial embolism<\/strong>: a clot (or other material such as fat or air) travels through the bloodstream and suddenly blocks an artery elsewhere.<\/li>\n<\/ul>\n<p>Arterial embolism is often more sudden and may be more dangerous because it causes abrupt loss of blood flow.
