AORTIC ISTHMUS Meaning and Definition

1. The aortic isthmus is a narrow anatomical region forming a section of the aorta, the largest artery of the human body, which connects the ascending aorta to the descending aorta. It begins at the connection point of the aortic arch and extends to the point where the descending aorta reaches the diaphragm.

   Located in the thoracic cavity, this region of the aorta is particularly important due to its proximity to important structures and its role in maintaining sufficient blood flow throughout the body. The aortic isthmus is situated posterior to the manubrium sterni and anterior to the thoracic vertebrae. It is bound by a series of vascular structures, such as the brachiocephalic artery (which gives off the right common carotid artery and right subclavian artery), the left common carotid artery, and the left subclavian artery.

   The aortic isthmus plays a fundamental role in ensuring optimal blood circulation. The narrowing of this region can lead to a condition called coarctation of the aorta, which is characterized by the constriction or narrowing of the aortic isthmus. This condition can impede blood flow to the lower part of the body, causing symptoms such as high blood pressure, weakness, and even heart failure.

   In summary, the aortic isthmus is a critical section of the aorta that connects the ascending and descending portions of the artery. Its location and function are crucial for maintaining healthy blood flow throughout the body.

2. A slight constriction of the aorta at the point of attachment of the ductus arteriosus, most evident in the fetus.

Etymology of AORTIC ISTHMUS

The word "aortic" comes from the Greek word "aortē", which means "large artery". It is derived from the Greek word "airo", meaning "to lift" or "to carry", suggesting the role of the aorta in carrying blood to the body.

The word "isthmus" has its roots in the Greek word "isthmos", which refers to a narrow strip of land connecting two larger parts of land. In medical terminology, "isthmus" is used to describe a narrow or constricted passage or region.

Therefore, the term "aortic isthmus" refers to a narrow or constricted region of the aorta.
