Pulmonary embolism occurs when clots form in the deep veins in the leg, which usually break off, travel, and lodge in the pulmonary veins, causing partial or complete blockage.

Pulmonary embolism is considered an emergency condition because it prevents blood and oxygen from flowing to the lungs, which can lead to tissue damage and death.

Symptoms of Pulmonary Embolism

Symptoms of pulmonary embolism include:

• Shortness of breath.
• Feeling of pain or pressure in the chest.
• Rapid heartbeat or rapid breathing.
• Cough.
• Bluish skin.
• Dizziness.

Risk Factors for Pulmonary Embolism

Risk factors for pulmonary embolism include:

• Genetic factors and medical history.
• Recent surgery on the legs.
• Aging, especially individuals over 40 years old.
• Obesity.
• Side effects of some medications, such as birth control pills, which may increase estrogen levels in the body.
• Smoking.
• Cancer or use of cancer medications.

Treatment of Pulmonary Embolism Using Interventional Radiology

Large pulmonary embolisms can be treated through catheter using interventional radiology. The catheter is inserted through the femoral vein and advanced to the pulmonary artery. Using specialized advanced devices, the doctor removes and dissolves the pulmonary emboli in less than an hour. Many patients have been treated successfully using this technique, demonstrating remarkable results.
