Plaque and thrombosis are not the same thing, but they are somewhat related. Plaque is a fatty substance deposited on the wall of blood vessel, which will lead to narrowing of blood vessel after a long time, then it may fall off or rupture, and the dislodged plaque will form thrombus with blood circulation. The plaque is mostly attached to the carotid artery or cerebral artery, and the thrombus is everywhere with the blood circulation, and the plaque is usually asymptomatic, and the symptoms appear only when the lumen of the blood vessel is narrowed. The thrombus will produce symptoms anywhere in the body, such as limb pain and hemiplegia, and the treatment methods are different. For plaque, you can choose simvastatin as lipid-lowering treatment, and for thrombus, thrombolytic treatment, such as urokinase.
