A pulmonary embolism is the name for a clot which has become trapped within the lung. It is commonly known as PE, which is a short form for embolism pulmonary. The clot which is stuck in the lung can lead to a blockage of blood flow. It is extremely risky when not properly treated.
Pulmonary Embolism – A Big Deal
Pulmonary embolism is a huge problem, since it’s very common but also extremely dangerous. It is a common occurrence, with nearly one million cases per every year within the US alone. It’s risky because about 25% of cases of pulmonary embolism result in sudden death , and as high as 33% of cases of pulmonary embolism is fatal. If you survive embolism in the pulmonary tract, there’s a chance of having a lower life expectancy and the possibility of complications that could affect the health. It is therefore crucial to ensure that it is diagnosed correctly and treated appropriately as it can be the difference in the world.
These clots were surgically removed from the lung arteries of the case of a patient suffering from massive embolisms in the pulmonary arteries.
How Does Pulmonary Embolism Start? – It All Starts With A DVT, a Clot That Forms In the Veins of the Leg
What really happens is when clots develop in the veins of your leg, which is known as a DVT, which stands for deep vein blood clots. Let’s try to describe this in a straightforward way to help us understand the pulmonary embolism more clearly.
Each time the heart beats, it circulates blood to the body via the arteries. The blood is pumped out with force and the flow through these arteries is rapid. Therefore, If you cut the arterial vein, blood would flow out rapidly and quickly due to the pressures that are high in the arteries. Once blood has reached the organ that is targeted it needs to be returned to the heart. It does so via the veins. The flow in the veins is slower with a lesser pressure. If you make a cut in one of the veins blood will certainly flow out, but because the pressure is not as high, it will not be the speed or force of an arterial bleeding. In fact , with a vein bleeding, you can easily stop circulation of blood by applying gentle pressure on the skin. If you have an arterial bleed, significant pressure will need to be applied.
Why do clots form? Three factors are believed to be essential in the formation of clots. First is hypercoagulability. The second one is flow pattern, and the thirdly, damage of the vessels. The three factors are referred to as the triad of Virchow. It’s not as complicated as I’ll go over it below.
The first in the triad was hypercoagulability. This basically signifies that, for some reason, that blood has a higher likelihood to develop blood clots due to changes in the chemical makeup inside it. These chemicals , referred to as factors that affect clotting influence the whole process of the formation of clots. In simple terms, they could make blood dense or extremely thin. Naturally, if blood is thick, then the risk of clots increases to develop. Certain medications, diseases, or genetic anomalies, can alter the clotting processes and cause blood to be much more likely to become thick. An excellent example can be birth control medications. They are, therefore, well-known risks for clot formation and embolism in the lungs.
Another component of the three-part triad was the flow pattern. When you draw the blood, put it in the cup, and then wait for an hour it would then form the form of a clot due to it not flowing. If you took the identical blood, and then pour it over a steep slope, it won’t clot since it’s flowing fast. The clotting components within the blood require time to function, and if blood is moving fast, they aren’t able to work. Because of this, clots are more likely to form in high pressure veins and is more likely to develop in lower pressure veins. When you stand on your feet or stroll, you push blood through your veins. If you are sitting for a long period of time it is slow and the risk of forming clots is higher. develop. The best examples are long flights on planes or patients who have undergone surgery and aren’t able to exercise for a long time. They are more at risk of developing blood clots within their veins and thus at risk of developing pulmonary embolism.
The third and final issue is a vessel injury. The veins and arteries of the body aren’t just un-lifeless tubes for blood to traverse; they comprise cells that are intelligent and constantly active, referred to by the name of endothelium. The cells are able to detect all kinds of things, from blood patterns to flow to the composition of blood. They are able to release chemicals and send signals when they wish certain things to take place. One example is when there is an injury to the vessel, which results in bleeding. Cells release chemical that draw cells to form clots in an effort in order to stop the bleeding. When cells are injured, they tend to form clots. Therefore it is a good idea to check for damaged vessels as a result of surgery or if someone suffered a fall or was hit by a leg clot could be more likely to develop.
It is now an knowledge of the causes that cause clots to form within the veins referred to as DVT’s. Pulmonary embolism typically begins with the formation of a DVT. We have discussed the triad of blood that is more likely form clots, slow flow and damage on the vein. As you can see that the ideal person to develop an artery clot would be one who is bed following an injury to their leg, and unable to exercise as a result of a disease like cancer that causes thicker blood. They may also be taking medications that lead to an increased risk of clot form. This would be an unbeatable storm.
Signs and Symptoms of a Pulmonary Embolism
The most frequently reported symptom for pulmonary embolism shortness of breath. This can occur quite quickly, whether in a relaxed state or while engaged in an activities. Other signs could be chest discomfort, nausea or even passing out. Patients may have recently experienced ankle swelling and leg discomfort as a result of the clot which started in the leg.
Treatment of Massive Pulmonary or High Risk Submassive Pulmonary Embolism
This is a medical emergency and require immediate medical attention. there are several treatments. Most often, the treatment selected will be based on the services offered at the hospital.
Clot Busting Medications The most popular alternative is to use the clot-busting medication called thrombolytics which is also known by the abbreviation lytics. They are usually administered via an IV, and they move to the clot so that they attempt to dissolve the clot. The main drawback to these drugs is the significant risk of bleeding which could be life-threatening, like a bleeding in the brain. However, the chance of getting treatment is thought as less as compared to the risks of not doing anything. However, there are instances where the dangers of these medications to stop clots is considered to be excessive like in patients who are suffering from bleeding problems or who have recently had surgery.
Open Heart Surgery – Sometimes it is necessary, especially when there is a massive clot burden or an clot that is floating in the heart, an open heart surgery is a preferred treatment choice. It opens the chest, and the clot removed. The drawback to this method is the inherent risks of open heart surgery. In the majority of situations that it is considered the risks associated with surgery are not as great as the chance that is not treating the embolism. The benefit of open heart surgery is that it will provide immediate stabilization when patients are unstable.
Catheter Based Treatment Catheter Based Treatment is the most advanced of treatments available. The treatment for pulmonary embolisms is by small tubes which are usually inserted into the veins in the leg. There are a variety of methods for treating the problem, and typically, injections of clot-busting drugs are administered directly the lung. One of the most exciting developments in recent times is the use of ultrasound tubes which are placed into the lungs through which small doses of medicines that break clots are administered. The benefit of this is the lower chance of bleeding opposed to conventional doses of medication to break up clots.
ECMO The term ECMO stands to mean extra-corporeal membrane oxygenation. It is a type of heart lung machine that could be utilized in the treatment of pulmonary embolisms that are instabile. This helps to restore circulation of the heart in case it stops or is in a state of severe dysfunction and ensures that the organs receive the blood they require. Additionally, the machine permits the circulation of blood in situations in which the lungs don’t have the capacity to function as they should. In short, ECMO can help stabilize an unstable situation as well as allow the patient to heal.
