Pulmonary Embolism (PE)
A pulmonary embolism (PE) occurs when a blood clot, often originating in the leg (deep vein thrombosis or DVT), travels to the lungs and blocks blood flow. A PE is a medical emergency that can cause sudden shortness of breath, chest pain, collapse, or death if untreated.
At The Medical Group of New Jersey, our pulmonologists provide rapid diagnosis using CT angiography and advanced cardiac testing, followed by personalized treatment with anticoagulation, thrombolysis, or interventional procedures when needed.
Symptom Onset & Initial Evaluation
Symptoms of a pulmonary embolism (PE) can develop suddenly and may range from mild to life-threatening, depending on the size and location of the clot. Because PE restricts blood flow to the lungs, oxygen levels can drop quickly, requiring urgent evaluation.
Common warning signs include:
- Sudden shortness of breath or rapid breathing
- Sharp, stabbing chest pain that worsens with deep breaths
- Cough, sometimes producing blood
- Fast heart rate, dizziness, or lightheadedness
- Leg pain or swelling, which may indicate a deep vein thrombosis (DVT)
If a pulmonary embolism is suspected, The Medical Group of New Jersey prioritizes immediate evaluation and coordinated care with its emergency and cardiology teams to ensure rapid diagnosis and treatment.
Diagnosis
Because a pulmonary embolism can become life-threatening within hours, prompt and accurate diagnosis is essential. Your pulmonologist may order several tests to confirm the presence, size, and source of the clot:
- CT Pulmonary Angiography (CTPA): The most definitive test, showing the exact location and extent of the embolism.
- D-dimer blood test: Detects elevated clotting activity, which can indicate the presence of a clot.
- Echocardiogram: Assesses the effect of the clot on heart function, especially the right ventricle.
- Doppler ultrasound of the legs: Identifies deep vein thrombosis (DVT), the most common source of pulmonary emboli.
Our team coordinates diagnostic imaging and testing quickly, allowing for immediate, life-saving intervention.
Treatment
The goal of PE treatment is to prevent the clot from growing, restore blood flow to the lungs, and reduce the risk of future clots.
Medication-Based Treatment
- Anticoagulants (blood thinners): Medications such as heparin or direct oral anticoagulants (DOACs) prevent new clots and stop existing ones from enlarging.
- Thrombolytic therapy: Used in severe or massive PE cases, these “clot-busting” drugs rapidly dissolve large clots to restore circulation.
Procedural & Surgical Treatments
For patients who cannot take anticoagulants or have extensive clots, advanced interventions may be required:
- Catheter-directed thrombolysis: A minimally invasive procedure that delivers medication directly to the clot for targeted removal.
- Inferior vena cava (IVC) filter: A device placed in the main abdominal vein to prevent new clots from traveling to the lungs.
- Surgical embolectomy: A rare but lifesaving surgery performed for massive embolisms causing circulatory collapse.
Your pulmonologist will tailor your treatment plan to the severity of your condition and collaborate closely with cardiology and vascular specialists to ensure the best outcomes.
Ongoing Management & Prevention
After the acute phase, long-term management includes preventing recurrence and addressing underlying causes such as DVT or clotting disorders. At The Medical Group of New Jersey, follow-up care includes:
- Regular anticoagulation monitoring
- Compression therapy for venous support
- Lifestyle counseling for hydration, mobility, and travel safety
- Evaluation for chronic thromboembolic pulmonary hypertension (CTEPH) in persistent cases
With early treatment and close follow-up, most patients recover fully and can resume normal activity within weeks to months.
