Anatomical space between the aorta and pulmonary artery


Aortopulmonary window[edit | edit source]

The aortopulmonary window is an anatomical space located in the mediastinum, the central compartment of the thoracic cavity. It is situated between the ascending aorta and the pulmonary artery. This space is clinically significant as it contains important structures and is a site where certain pathological conditions can manifest.

Anatomy[edit | edit source]

The aortopulmonary window is bordered anteriorly by the ascending aorta and posteriorly by the pulmonary artery. Superiorly, it is bounded by the aortic arch, and inferiorly, it is limited by the left atrium and the left main bronchus.

Contents[edit | edit source]

The aortopulmonary window contains several important structures, including:

Clinical significance[edit | edit source]

The aortopulmonary window is a site where lymphadenopathy can occur, often due to infections, malignancies, or inflammatory conditions. Enlargement of lymph nodes in this area can compress adjacent structures, leading to clinical symptoms such as hoarseness due to compression of the left recurrent laryngeal nerve.

Pathological conditions[edit | edit source]

Imaging[edit | edit source]

The aortopulmonary window can be visualized using imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI). These modalities help in assessing the presence of masses, lymphadenopathy, or other abnormalities in this region.
