What is a concentric thrombus?

A concentric thrombus is a type of blood clot that forms in layers around a central core, resembling concentric rings. This structure is often associated with conditions like atherosclerosis, where repeated cycles of clotting and healing can lead to layer formation. The layers can vary in composition, with different types of cells and fibrin, and may influence the thrombus's stability and potential for embolization. Understanding concentric thrombi is important in cardiovascular medicine, as they can impact blood flow and increase the risk of complications.
