What is another word for abdominal aortic aneurysm?
An abdominal aortic aneurysm is also called AAA or triple A. A thoracic aortic aneurysm refers to the part of the aorta that runs through the chest.
What is abdominal aorta and iliac arteries?
You have two iliac arteries: one on the right side of the body (called the right common iliac artery) and one on the left (called the left common iliac artery). Both common iliac arteries branch from the base of the aorta. This part of the aorta is called the abdominal aorta because it’s in your belly.
What is a descending aorta definition?
The descending aorta begins after the origin of the left subclavian artery from the aortic arch and continues down through the chest to the diaphragm. The segment of the aorta below the diaphragm is referred to as the abdominal aorta. The descending aorta provides important blood flow to the spinal cord.
What is triple A medical term?
An abdominal aortic aneurysm (AAA) is a bulge or swelling in the aorta, the main blood vessel that runs from the heart down through the chest and tummy. An AAA can be dangerous if it is not spotted early on.
What is first branch of abdominal aorta?
the celiac trunk
The first and often largest visceral branch of the abdominal aorta is the celiac trunk. The celiac trunk quickly bifurcates or trifurcates into branches.
What are the abdominal arteries?
The abdominal arteries arise from the abdominal aorta and are comprised of three groups of arteries: unpaired visceral arteries, paired visceral arteries, and parietal arteries.
What region is the bifurcation of the abdominal aorta?
The abdominal aorta bifurcates at the L4 level. The small median or middle sacral artery arises from the posterior surface of the abdominal aorta close to the bifurcation and descends vertically along the pelvic surface of the sacrum.
Why is the abdominal aorta also called the descending aorta?
Instead of continuing upwards, the aorta then forms a curve called the aortic arch. By the end of that curve, the aorta is directed downwards. This portion is called the descending aorta. The descending aorta travels down the chest and becomes the abdominal aorta when it crosses the diaphragm.
Where is the ascending and descending aorta?
Ascending aorta is the first part of the aorta which begins at the aortic valve, extends 2 inches and becomes the aortic arch while descending aorta is the third portion of the aorta which spans from the level of T4 to T12 and becomes the abdominal aorta.
What is an aorta?
The aorta is the largest artery of the body and carries blood from the heart to the circulatory system. It has several sections: The Aortic Root, the transition point where blood first exits the heart, functions as the water main of the body.
What does abdominal aorta mean?
The abdominal aorta is the largest artery in the abdominal cavity. As part of the aorta, it is a direct continuation of the descending aorta (of the thorax). The abdominal aorta begins at the level of the diaphragm, crossing it via the aortic hiatus, technically behind the diaphragm, at the vertebral level of T12.
What are the 3 major branches of the abdominal aorta?
– 3 single anterior visceral branches (coeliac, superior mesenteric artery, inferior mesenteric artery) – 3 paired lateral visceral branches (suprarenal, renal, gonadal) – 5 paired lateral abdominal wall branches (inferior phrenic and four lumbar) – 3 terminal branches (two common iliac arteries and the median sacral artery)
What portion of the aorta is in the abdomen?
– Open aneurysm repair: A large incision is made in the abdomen to repair the aneurysm. – Endovascular aneurysm repair (EVAR): A small incision is made in the groin. – Fenestrated stent graft: When the aneurysm is juxtarenal (at the kidneys) or involves the arteries of the kidneys, the prior standard treatment has been open surgery.
What is palpable abdominal aorta and what could be?
The aortic pulse is palpable in thin individuals, but is usually impalpable in muscular or obese patients. Palpation of the aorta is primarily to detect an abdominal aortic aneurysm (AAA) which may be asymptomatic but rupture of which can have a very high mortality.
