What is the ascending aorta? The ascending aorta is the first part of the aorta, which is the largest blood vessel in your body. It comes out of your heart and pumps blood through the aortic arch and into the descending aorta. The aorta plays an essential role as the main “pipe” supplying blood to your entire body.

2024年4月21日 · The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta. It terminates at the level of L4 by bifurcating into the left and right common iliac arteries.

2008年7月8日 · The presence of AD into the arch aorta mandates a determination of the need for arch resection. Typically, if AD is present into the distal ascending aorta or beyond, adjunctive use of deep hypothermic circulatory arrest is indicated …

2023年8月8日 · The aortic arch is the section of the aorta between the ascending and descending aorta. As it arises from the ascending aorta, the arch runs slightly backward and to the left of the trachea. The distal segment of the aortic arch then traverses downwards at …

The ascending aorta segment is of significant due to its susceptibility to aortic dissection, two times more than in the descending aorta. Early detection of dissection is critical because it allows for prompt intervention to prevent potentially life-threatening complications.

2024年11月9日 · Ascending aorta: The ascending aorta is the first section of the aorta, connected to the left ventricle, which pumps oxygenated blood to the body. It begins at the aortic valve, which regulates blood flow from the heart into the aorta. Aortic arch: This is the part of the aorta that curves upward toward the head and neck. It starts where the ...

2023年3月6日 · One case report details a patient with a double-lumen aortic arch and an anomalous left pulmonary artery originating from the ascending aorta. The authors suggest it as a case of bilateral PFAA, with the right fifth aortic arch creating the double-lumen aorta and the left fifth aortic arch creating the anomalous pulmonary artery.

2023年10月30日 · Most common one, and the one we will use in this article, is the classification of the aorta into three parts; the ascending aorta, aortic arch and the descending aorta. The descending aorta is the longest part, further subdivided into thoracic and abdominal aorta, with the diaphragm being the anatomical division between the two.

2023年10月30日 · From its origin, it ascends anteriorly and to the right, passing posterior to the left half of the sternum where it transitions into becoming the aortic arch, roughly at the level of the sternal angle (manubriosternal joint). It is roughly 5cm in length and is the widest segment of the aorta, typically between 3-4cm in diameter.

The ascending aorta includes the aortic root and sinuses of Valsalva where the blood supply to your heart, via the coronary arteries, originates. The ascending aorta continues upward to form the aortic arch, where the oxygenated blood supply to your head originates.
