Pulmonary embolism risk
The presence of a thrombus in a deep vein in the legs and the existence of a previous episode of pulmonary embolism are the most important risk factors for pulmonary embolism.
Pulmonary embolism risk factors for development of thrombus (blood clot) are venous stasis (slow blood flow), abnormal thrombogenesis and trauma of the vessel walls. The pulmonary embolism risks are:
Thrombi grow especially when blood flow is not normal. Decreased blood circulation rate may be due to:
Some people show a condition in which blood coagulates too fast or too easy. These people are prone to develop large thrombi which break and travel to the lungs. Conditions that may increase thrombus formation are:
The blood coagulates in the arteries or in the veins probably after they were injured. Vein damage can be caused by:
Other risk factors include:
In order for the thrombus to form, some conditions are needed, united as the Virchow's triad:
There are diseases that meet one of these conditions, so they can cause / precipitate a pulmonary embolism, considered risk factors:
Complications of pulmonary embolism may include:
An aggressive stance will be taken into account when a pulmonary embolism is considered life-threatening for the patient. Death by pulmonary embolism usually occurs within 30 minutes of symptoms.
Important notes about pulmonary embolism
Pulmonary embolism is given by a thrombus (most commonly), air, fat, pieces of plaque buildup, fluid. It is a disease with high mortality level. Oral anticoagulant therapy has as side effects bleeding, so present yourself to the doctor when you notice blood in the urine, a new heavy vaginal bleeding, red or dark stool, bleeding from the nose that does not stop, various frequent bruises. In people with chronic pulmonary embolism oral treatment is necessary for the entire life. Inferior vena cava filter is indicated only if there is a high risk of death by pulmonary embolism or when the anticoagulant treatment is not able to be taken due to the bleeding that can occur.
