Venous Embolism: A Closer Look at the Blood Vessels
When it comes to the cardiovascular system, the veins play a crucial role in carrying deoxygenated blood back to the heart. Unlike the muscular arteries, veins are less muscular and are located closer to the surface of the skin. Interestingly, there are two exceptions to this rule: the pulmonary and umbilical arteries. These particular arteries, much like veins, carry deoxygenated blood towards the heart. Eventually, the veins connect with these arteries, forming a vital network within the body.
However, there are instances when a venous embolism occurs in a systemic vein, leading to potentially serious consequences. This embolism eventually finds its way into the pulmonary artery, resulting in what is known as a pulmonary embolism. It is worth noting that the majority of venous embolisms occur in the femoral veins located in the legs.
Symptoms of a Venous Embolism
When it comes to a venous embolism, there are several symptoms to watch out for. A telltale sign is the presence of redness around the affected area. Since the pulmonary artery is responsible for supplying blood to the lungs, the symptoms that arise from a venous embolism often revolve around oxygen deprivation. These symptoms tend to appear suddenly and progress rapidly.
Shortness of breath and chest pain during breathing are among the most common symptoms experienced by individuals with a venous embolism. In addition, one might also notice an increase in breathing rate and heart rate. If left untreated, the embolism can lead to loss of consciousness or, in severe cases, sudden death. It is important to note that a significant warning sign of a serious pulmonary embolism is a bluish discoloration around the lips and fingers.
