Tissue death following embolism. Close-up of the gangrenous toes of a patient, caused by a loss of blood supply due to an embolism. An embolism is a piece of material (typically a blot clot) that causes a blockage inside a blood vessel. Here, it has blocked the blood supply to the toes, causing the tissue to die (necrosis) and become gangrenous.
