Is thromboembolism an emergency?
Often, yes. A pulmonary embolism (a clot in the lungs) is a medical emergency and can be fatal within hours, so call 911 for sudden shortness of breath, chest pain, or fainting. A deep vein thrombosis in the leg is urgent because it can break loose and travel to the lungs.
Thromboembolism means a blood clot has blocked a blood vessel. Whether it is an emergency depends on where the clot is and how it is behaving. Two situations account for nearly all serious cases: a deep vein thrombosis (DVT) in the leg and a pulmonary embolism (PE) in the lungs.
Call 911 Now for These Signs
A pulmonary embolism is life-threatening and can kill within hours. Call 911 immediately, rather than driving yourself, if you have any of the following:
- Sudden shortness of breath, even at rest
- Chest pain that gets sharper when you breathe in, cough, or bend
- A racing or pounding heartbeat
- Lightheadedness, fainting, or collapse
- Coughing up blood or blood-streaked mucus
- Bluish lips or fingertips
These are the classic warning signs of a clot in the lungs. Fainting and a fast heart rate can signal a large clot straining the heart, which needs treatment within minutes.
A Leg Clot (DVT) Is Urgent Too
New swelling, pain, warmth, or red or discolored skin in one leg can be a DVT. A DVT is not always an immediate life threat by itself, but it can break off and travel to the lungs, turning into a PE without warning. That is why a suspected leg clot should be evaluated promptly the same day, not watched at home for days.
What Raises the Emergency Level
Your risk of a dangerous clot is higher after recent surgery, a long hospital stay or bed rest, long-distance travel, a leg cast, pregnancy or recent childbirth, active cancer, estrogen-containing birth control or hormone therapy, or a previous clot. If you have any of these risk factors and develop warning signs, treat it as an emergency and do not wait it out.
When It May Not Be a Clot
A muscle cramp, a pulled calf muscle, or brief breathlessness after exertion often has a clear cause and eases with rest. Mild, stable symptoms with an obvious explanation are less likely to be a clot, but because a missed PE can be fatal, err on the side of caution when anything is new, one-sided, or worsening.
