The physical composition of the embolic material is the defining feature for classification, and this composition reflects the underlying pathophysiologic mechanism of the embolus' formation. Furthermore, different types of emboli result in different types of embolisms, each with distinct clinical characteristics.
The pulmonary embolism rule-out criteria (PERC) helps assess people in whom pulmonary embolism is suspected, but unlikely. Unlike the Wells score and Geneva score , which are clinical prediction rules intended to risk stratify people with suspected PE, the PERC rule is designed to rule out the risk of PE in people when the physician has already ...
An embolism can cause partial or total blockage of blood flow in the affected vessel. [2] Such a blockage (vascular occlusion) may affect a part of the body distant from the origin of the embolus. An embolism in which the embolus is a piece of thrombus is called a thromboembolism. An embolism is usually a pathological event, caused by illness ...
Generally speaking the risk for thrombosis increases over the life course of individuals, depending on life style factors like smoking, diet, and physical activity, the presence of other diseases like cancer or autoimmune disease, while also platelet properties change in aging individuals which is an important consideration as well.

This is often provoked with physical activity and relieved with rest. Pain and muscle aching may build up with walking, and accelerate with light jogging or walking uphill. Often, pain is relieved after several minutes of rest. [3] However, affected individuals are limited to short spurts of activity, impairing their quality of life.
Prevention of atherosclerosis, which is a major risk factor of arterial embolism, can be performed e.g. by dieting, physical exercise and smoking cessation. [ 6 ] In case of high risk for developing thromboembolism, antithrombotic medication such as warfarin or coumadin may be taken prophylactically.
Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
Fat embolism syndrome occurs when fat enters the blood stream (fat embolism) and results in symptoms. [1] Symptoms generally begin within a day. [1] This may include a petechial rash, decreased level of consciousness, and shortness of breath. [1] Other symptoms may include fever and decreased urine output. [2] The risk of death is about 10%.
