A CT scan shows details of the bones, muscles, fat, and organs. CT with contrast enhances the image of the blood vessels in the lungs. Contrast is a dye-like substance injected into a vein that causes the organ or tissue under study to show up more clearly on the scan. Magnetic resonance imaging MRI.
This imaging test uses a combination of a magnetic field, radiofrequencies, and a computer to make detailed images of organs and structures within the body. Duplex ultrasound US. This type of vascular ultrasound is done to assess blood flow and the structure of the blood vessels in the legs. Blood clots from the legs often dislodge and travel into the lung.
US uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs. Lab tests. Blood tests are used to check the blood's clotting status, including a test called D-dimer level.
Other blood work may include testing for genetic disorders that may contribute to abnormal clotting of the blood.
Arterial blood gases may be checked to see how much oxygen is in the blood. Electrocardiogram EKG. This is one of the simplest and fastest tests used to evaluate the heart. Electrodes small, sticky patches are placed at certain spots on the chest, arms, and legs. The electrodes are connected to an EKG machine by lead wires. The electrical activity of the heart is measured, interpreted, and printed out.
Also described as blood thinners, these medicines decrease the ability of the blood to clot. This helps stop a clot from getting bigger and keep new clots from forming.
Examples include warfarin and heparin. Fibrinolytic therapy. Also called clot busters, these medicines are given intravenously IV or into a vein to break down the clot.
These medicines are only used in life-threatening situations. Vena cava filter. A small metal device placed in the vena cava the large blood vessel that returns blood from the body to the heart may be used to keep clots from traveling to the lungs.
These filters are generally used when you can't get anticoagulation treatment for medical reasons , develop more clots even with anticoagulation treatment, or when you have bleeding problems from anticoagulation medicines. Pulmonary embolectomy. Rarely used, this is surgery done to remove a PE. A filter can be placed in the inferior vena cava in order to prevent any clots from migrating from the legs into the lungs Fig.
This is a prevention strategy and will do nothing after the fact. In contrast, thrombectomy and embolectomy are rare surgical procedures that are used to remove a clot in the legs or lungs, respectively Streiff et al.
The first step to prevent PE is becoming aware of the risk. If you are at an increased risk, a doctor can recommend medicines or graduated compression stockings to help prevent a DVT from occurring.
As the risk of PE also increases when sitting for extended periods of time, this can be mitigated by getting up to walk, wearing loose-fitting clothes while travelling, and exercising your legs while seated. Stretching your leg muscles by lifting your heels off the ground and setting them down again Fig. Finally, maintaining a healthy weight and active lifestyle is key to reducing the risk of PE Konstantinides et al.
Common complications include decreased quality of life , functional limitations , incomplete thrombus resolution , and abnormal pulmonary artery pressure and right ventricular function , among others.
OOne of the most severe complications, chronic thromboembolic pulmonary hypertension CTEPH , is associated with a high risk of death. It occurs in just under 0. As already discussed, the best clinical outcome is when the embolism never makes it to the lungs.
And the best way to prevent the embolism from migrating to the lungs is to prevent it from ever forming in the lower extremities in the first place. Clinician management of PE has changed over the years, with many excellent tools available to clinicians to allow them to bypass unnecessary tests and delay times.

DVT can become dangerous if the blood clot breaks off and travels through the bloodstream to the lungs.
This causes a blockage called a pulmonary embolism PE and can be life-threatening. Think of pulmonary embolism as a complication of deep vein thrombosis , explains Roy Silverstein, MD , a professor and chair in the Medical College of Wisconsin's division of hematology and oncology in Milwaukee. Obi says. DVT and PE aren't always detected for what they are. Silverstein says. However, because PE can lead to sudden death, it's critical to seek medical treatment right away if you think you might be experiencing any of the telltale symptoms.
An estimated 60, to , of them die, and most are sudden deaths because the fatal PE goes unrecognized. That need not be the case, however. While people over 60 years of age are more likely to develop DVT and PE, people of all ages can be affected.
The fact is that you can reduce the risk of DVT and PE through early symptom recognition and management. Know the symptoms of DVT and PE, talk to your doctor about the risk factors for developing them, and seek emergency medical care immediately if you experience any of the symptoms. Spinal or epidural blood clots hematoma. People who take PRADAXA and have medicine injected into their spinal and epidural area, or have a spinal puncture have a risk of forming a blood clot that can cause long-term or permanent loss of the ability to move paralysis.
Your risk of developing a spinal or epidural blood clot is higher if:. If you take PRADAXA and receive spinal anesthesia or have a spinal puncture, your healthcare provider should watch you closely for symptoms of spinal or epidural blood clots.
Tell your healthcare provider right away if you have back pain, tingling, numbness, muscle weakness especially in your legs and feet , loss of control of the bowels or bladder incontinence.
