Major aortopulmonary collateral arteries (MAPCAs) synonyms
What other names are the Major aortopulmonary collateral arteries (MAPCAs) known by? Synonyms and other terms with which Major aortopulmonary collateral arteries (MAPCAs) are known.
Major aortopulmonary collateral arteries (MAPCAs), also known as collateral vessels or bronchial arteries, are an important anatomical feature in certain congenital heart defects. These collateral arteries serve as alternative pathways for blood flow between the aorta and the pulmonary arteries, bypassing the normal route through the heart.
In individuals with certain congenital heart defects, such as Tetralogy of Fallot or Pulmonary Atresia, the pulmonary arteries may be underdeveloped or completely blocked. This can lead to inadequate blood flow to the lungs, resulting in oxygen deprivation and other complications. MAPCAs develop as a compensatory mechanism to ensure sufficient blood supply to the lungs.
The term "major" in MAPCAs refers to the fact that these collateral arteries are larger in size compared to the usual bronchial arteries found in healthy individuals. They arise from various sources, such as the descending aorta, subclavian arteries, or coronary arteries, and form an extensive network of vessels that supply blood to the pulmonary arteries.
MAPCAs can vary in number, size, and location, making each case unique. The presence of these collateral arteries can be detected through imaging techniques such as echocardiography, magnetic resonance angiography (MRA), or cardiac catheterization.
Understanding the presence and characteristics of MAPCAs is crucial for the management of congenital heart defects. Surgeons may need to consider these collateral vessels during corrective surgeries, as they can impact the surgical approach and potential complications. Additionally, interventions such as embolization or stenting may be required to manage excessive blood flow through the collateral arteries.
In conclusion, major aortopulmonary collateral arteries (MAPCAs) are alternative pathways for blood flow in individuals with certain congenital heart defects. These collateral vessels, also known as bronchial arteries, ensure sufficient blood supply to the lungs when the normal route through the heart is compromised. Understanding the presence and characteristics of MAPCAs is essential for effective management and treatment of congenital heart defects.
