Pulmonary embolism

In case of pulmonary embolism most frequently deep vein thrombosis is the underlying cause. In the venal system a thrombus breaks loose (blood clot or more rarely fat, air, foreign tissue), travels through the bloodstream into the pulmonary vessels and causes sudden obstruction.

Symptoms may vary depending of the diameter of the obstructed vessel: severe chest pain, cough (occasionally with blood in the sputum), dyspnea, fast breathing, rapid heartbeat, sweating, shivering with cold, loss of consciousness.

With the help of lung perfusion test combined with CT imaging, pulmonary embolism can effectively be diagnosed.
