What is a pseudoaneurysm?
A pseudoaneurysm is a blood clot that forms in an artery or, rarely, in the heart as a result of trauma. The most common form is a femoral pseudoaneurysm.
You may wonder why this condition is called pseudo or false. Despite its name, a pseudoaneurysm is a real disease and can be life-threatening if it ruptures. It is called false because not all three layers of the artery wall are damaged. In a true aneurysm, damage to all three layers is observed.
Some pseudoaneurysms are harmless and heal on their own, although sometimes they are serious. In the event of a rupture, severe complications or death can occur. Any unusual symptoms should be noted and prompt medical attention should be sought.
Pseudoaneurysms are divided into several types, namely:
- Femoral pseudoaneurysm;
- Aortic pseudoaneurysm;
- Visceral pseudoaneurysm, etc.
Typical symptoms include:
- A painful or bulging bulge under the skin;
- Pain and increased sensitivity to touch;
- Skin discoloration or bruising;
- Numbness or tingling.
Left ventricular and aortic pseudoaneurysms present with a variety of symptoms, including:
- Chest pain;
- Shortness of breath;
- Irregular heartbeat;
- Signs of heart failure.
Common causes include:
- Post-surgical complications;
- Traumatic injury;
- Pancreatitis.
Injury to an artery can also cause a hematoma. However, a hematoma is a collection of blood that does not have a surrounding wall.
Possible complications include:
- Nerve pain;
- Deep vein thrombosis;
- Gangrene;
- Internal bleeding and rupture.
Some pseudoaneurysms, especially those that form in the heart, can be fatal - in such clinical cases, early diagnosis and treatment are the only way to save lives.
