What is a pulmonary aneurysm?

What is a pulmonary aneurysm?

A pulmonary artery aneurysm (PAA) is an excessive dilatation involving all three layers of the vessel wall in the main pulmonary artery and/or any of its main branches. It is a rare but severe pathological condition with an unknown prevalence based on a large population in previous statistics.

What are the symptoms of a pulmonary aneurysm?

Reported symptoms include hemoptysis, shortness of breath, chest pain, palpitations or syncopal episodes (7-10). Additional symptoms attributed to extrinsic bronchial compression by a large PAA or PAPA may include cough, worsening dyspnea, cyanosis or pneumonia (10-12).

How do you treat a pulmonary aneurysm?

Treatment. Treatment can be either conservative (medical) or surgical. Surgical repair is recommended if the aneurysms are large, > 6 cm, or if they are symptomatic, regardless of the size, because the risk of rupture or dissection is high in the case of symptoms.

Is a pulmonary aneurysm fatal?

Unlike dissection in systemic arteries, pulmonary artery dissection is usually lethal. Diagnosis of this condition is very rarely made during life and most commonly diagnosed at autopsy in cases of sudden and unexpected death.

How common is pulmonary aneurysm?

Pulmonary involvement is found in less than 5% of patients, most commonly as pulmonary artery aneurysms. Hemoptysis is the most common clinical symptom, usually caused by rupture of an aneurysm. This may be life threatening or fatal. Other pulmonary symptoms include cough, dyspnea, and chest pain.

What happens when you have a pulmonary aneurysm?

Pulmonary embolism (PE) occurs when a blood clot gets lodged in an artery in the lung, blocking blood flow to part of the lung. Blood clots most often start in the legs and travel up through the right side of the heart and into the lungs. This is called DVT.

How is pulmonary aneurysm diagnosed?

CT pulmonary angiography ― also called CT pulmonary embolism study ― creates 3D images that can detect abnormalities such as pulmonary embolism within the arteries in your lungs. In some cases, contrast material is given intravenously during the CT scan to outline the pulmonary arteries.

What do you do for an aneurysm?

The only way to treat an aneurysm is to have it repaired with surgery or an endovascular procedure. Sometimes, surgery isn’t possible, or it may pose more danger than the aneurysm. Careful monitoring and medication may be best in that case. Your doctor will figure out the size, type, and location of the aneurysm.

As the lungs fill with blood, breathing may become more labored. Other signs of a pulmonary aneurysm include weakness and difficulty moving around. A bulging pulmonary artery can also press on the laryngeal nerve, causing hoarseness, according to an article in the Indian Journal of Radiology and Imaging.

What are causes of aneurysm and pseudo aneurysm?

A pseudoaneurysm, sometimes called a false aneurysm, occurs when a blood vessel wall is injured, and the blood is contained by the surrounding tissues . In a true aneurysm, the artery or vessel is dilated, sometimes causing a blood-filled sac to form. Both aneurysms and pseudoaneurysms can occur within the heart.

What is treatment for pulmonary aneurysm?

The traditional treatment offered to patients with pulmonary artery aneurysms was open thoracotomy followed by resection of the aneurysm and the involved lobe.

Can a pulmonary artery rupture be fatal?

To conclude, pulmonary artery rupture is a life-threatening and potentially lethal complication following pulmonary artery catheterisation. Some of these deaths may fall under the purview of the inquiring authorities and forensic pathologists due to their in-hospital outcome.
