Pulmonary artery dilatation

Pulmonary artery dilatation refers to the abnormal enlargement or widening of the pulmonary artery, which is the major blood vessel responsible for carrying deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.

This condition can be indicative of underlying cardiac or pulmonary issues, such as pulmonary hypertension, congenital heart defects, or connective tissue disorders.

The dilatation can affect blood flow dynamics, potentially leading to increased pressure in the pulmonary circulation and strain on the right side of the heart.

Over time, this can contribute to right heart failure if not managed effectively.

Patients may experience symptoms such as shortness of breath, fatigue, and chest pain, although mild cases might be asymptomatic and discovered incidentally during imaging for other reasons.

Pulmonary artery dilatation can be detected using imaging techniques such as echocardiography, computed tomography (CT), and magnetic resonance imaging (MRI), which are encompassed in torso, head & torso, and whole body scan protocols.

These imaging modalities help visualize the structure and size of the pulmonary artery, assess blood flow, and evaluate any associated cardiac anomalies.

Management of this condition depends on the underlying cause and severity, ranging from medical therapy to surgical intervention in more severe cases.

Regular monitoring and follow-up are crucial for managing potential complications.
