The resulting traveling clot is known as an embolus (plural emboli). Pulmonary embolism refers to an embolus that lodges in the pulmonary circulation. An embolism in which the embolus is a piece of thrombus is called a thromboembolism. This can be due to ischemia, thrombus, embolus (a lodged particle) or hemorrhage (a bleed). The free-moving thrombus is called an embolus. It is possible to assess whether a thrombus will become an embolus through echocardiography. I include chronic kidney failure, heart failure, subarachnoid haemorrhage and pulmonary embolus. The results of this may include pulmonary embolus, transient ischaemic attacks, or stroke. A pulmonary embolus is a common cause of death in patients with cancer and stroke. It is primarily used to detect a pulmonary embolus. Some arrhythmias promote blood clotting within the heart, and increase risk of embolus and stroke. A pathological example of dead zone would be a capillary blocked by an embolus. Additionally males will gain an embolus on the pedipalps and tibial apophysis (mating hooks). Because an embolus arises from elsewhere, local therapy solves the problem only temporarily. Kutner suggests there is a fat embolus.
