Procedures
The abdominal aorta in a nutshell. It supplies all of the abdominal organs, and its terminal branches go on to supply the pelvis and lower limbs. It also supplies the undersurface of the diaphragm and parts of the abdominal wall.
Self-care
The abdominal aorta has: 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)
Nutrition
The goal of abdominal aortic aneurysm treatment is to prevent an aneurysm from rupturing. Treatment may involve careful monitoring or surgery. Which treatment you have depends on the size of the aortic aneurysm and how fast it's growing.
What does the abdominal aorta supply to the pelvis?
The aorta supplies oxygenated blood to most of the body. Since so much blood flows through the aorta, it is an extremely sensitive blood vessel during trauma or certain types of medical conditions. If it is cut or ruptured, the aorta can lose the majority of the body's total blood volume in a few minutes, which can lead to death.

What is the para-aortic?
Introduction. The para-aortic lymph nodes (PANs) are located around the abdominal aorta and inferior vena cava and are the regional lymph nodes of the intraperitoneal organs.
Where is the para-aortic located?
Para-aortic lymph nodes (often shortened to para-aortic nodes) are part of the retroperitoneal nodes, and are located anterior to the left lumbar trunk 1 and above and below the left renal vein prior to the flow of lymph into the cisterna chyli 2-4.
What are the para-aortic nodes?
The periaortic lymph nodes (also known as lumbar) are a group of lymph nodes that lie in front of the lumbar vertebrae near the aorta. These lymph nodes receive drainage from the gastrointestinal tract and the abdominal organs. Lymph nodes (Paraaortic labeled in center in blue.)
What drains to para-aortic lymph nodes?
The para-aortic nodes, also known as the lumbar aortic nodes, drain lymph from the kidneys, suprarenal glands, testes, ovaries, uterus, and uterine tubes.
Which organs are in the retroperitoneal space?
The area in the back of the abdomen behind the peritoneum (the tissue that lines the abdominal wall and covers most of the organs in the abdomen). The organs in the retroperitoneum include the adrenal glands, aorta, kidneys, esophagus, ureters, pancreas, rectum, and parts of the stomach and colon.
What is para-aortic retroperitoneal lymph node?
Retroperitoneal lymph nodes are located in a specific part of the abdominal cavity immediately behind the intestine that is closer to your backbone than your belly button. The swelling of the nodes themselves is referred to as lymphadenopathy.
How are para-aortic lymph nodes treated?
Although para-aortic lymph node metastasis is defined as distant metastasis, these patients are frequently treated with radiation therapy, which can lead to cure (5-7).
Where do the pre aortic nodes of the posterior abdominal wall drain?
The preaortic nodes receive lymph from both primary and accessory gastrointestinal organs ranging from the abdominal oesophagus to the anus. The nodes then drain to the intestinal trunk (see below) before draining to the cisterna chyli.
What are stomach lymph nodes?
The lymph nodes that become inflamed are in a membrane that attaches the intestine to the lower right region of the abdominal wall. These lymph nodes are among the hundreds that help your body fight disease. They trap and destroy microscopic "invaders" like viruses or bacteria.
Where are the abdominal lymph nodes?
The retroperitoneal, or lumbar lymph nodes are commonly located around the abdominal aorta and inferior vena cava, forming three distinct groups: left lumbar (para-aortic), right lumbar (para-caval), and intermediate lymph nodes. The latter group is situated between the two great abdominal vessels.

How do you perform abdominal lymphatic massage?
To massage the stomach, press your palms flat down onto the area in between your hip bones "With hands overlapping, make circular movements around the navel button 5 times" she says. "Then pinch the entire stomach area," for about a minute until the skin is slightly pink.
What is the aorta?
The aorta supplies oxygenated blood to most of the body. Jan-Otto / Getty Images. Since so much blood flows through the aorta, it is an extremely sensitive blood vessel during trauma or certain types of medical conditions.
What is the most common condition that affects the abdominal aorta?
The most common condition to affect the abdominal aorta is an abdominal aortic aneurysm. An abdominal aortic aneurysm consists of a weakening of the wall of the aorta just above the point where it bifurcates into the left and right common iliac arteries.
What is the largest artery in the abdominal cavity?
By the time the aorta reaches the abdomen, it has tapered to a width of about 2 centimeters wide, making it the largest artery in the abdominal cavity. 1 Like other blood vessels, the wall of the abdominal aorta is made up of three distinct tissue layers: the thin inner layer (tunica intima), the thick middle layer (tunica media), and the thin outer layer (tunica adventitia). that have the ability to constrict and relax as needed to adjust for high and low blood pressures.
How many arteries branch off of the abdominal aorta?
There are five arteries that branch off of the abdominal aorta:
Where does the descending aorta travel?
The descending aorta travels down the chest and becomes the abdominal aorta when it crosses the diaphragm, at about the twelfth thoracic vertebra. From there travels down to where it bifurcates into the left and right common iliac arteries.
Where does the aorta start?
The aorta starts at the left ventricle of the heart and curves around toward the feet. The curve is known as the aortic arch. The entire aorta stretches from the thoracic cavity to the abdomen. All of the blood flow leaving the left ventricle flows through some or all of the aorta.
Which organ is the conduit for blood to flow to the body?
As the largest blood vessel in the body, the aorta provides a conduit for all the blood flowing to the body from the heart other than the blood that flows to the heart itself. The abdominal aorta conducts blood to organs in the abdominal cavity as well as to the legs and feet.
How big is an aortic aneurysm?
Guidelines for surgical intervention include: Aneurysm size > 5 cm (about 2 inches)
What is specific treatment?
Specific treatment is based on: Your age, overall health, and medical history. Extent of the disease. Your signs and symptoms. Your tolerance of specific medications, procedures, or therapies. Expectations for the course of the disease. Your opinion or preference.
What happens when an aneurysm grows in size?
As an aneurysm grows in size, the wall of the aorta becomes weaker and weaker, which means surgical intervention may be needed. The goal of any treatment strategy is to preventing the rupture of an aneurysm by controlling the growth of the aneurysm.
What is the abdominal aorta?
The abdominal aorta is a continuation of the descending thoracic aorta. It supplies all of the abdominal organs, and its terminal branches go on to supply the pelvis and lower limbs. It also supplies the undersurface of the diaphragm and parts of the abdominal wall. It begins at T12 and ends at L4, where it divides into ...
Which organ is parallel to the aorta?
Running parallel to the aorta on its right-hand side is the inferior vena cava, the cisterna chyli, the beginning of the azygos vein, and the para-aortic lymph nodes. Running on its left-hand side is the left sympathetic trunk and the para-aortic lymph nodes. Organs situated directly in front of the aorta include the stomach, duodenum and pancreas.
What is the largest blood vessel in the abdomen?
The abdominal aorta is the largest blood vessel in the abdomen. It has a number of important relationships and branches, which very commonly appear in exam questions and anatomy spotters. I hope this anatomy guide is helpful.
Where is the abdominal aorta located?
The abdominal aorta is located on the posterior abdominal wall in the retroperitoneal space of the abdomen. It descends on the left of the inferior vena cava (IVC) over the anterior surface of the bodies of the lumbar vertebrae and follows the curvature of the lower spine.
What organs does the sphincter supply?
It supplies all of the abdominal organs , and its terminal branches go on to supply the pelvis and lower limbs. It also supplies the undersurface of the diaphragm and parts of the abdominal wall.
Where does the azygos vein enter the abdomen?
It enters the abdomen through the aortic opening of the diaphragm, which is located beneath the median arcuate ligament between the crura of the diaphragm at T12. It is accompanied through the aortic opening by the azygos vein and the thoracic duct.
How many terminal branches are there in the iliac artery?
3 terminal branches (two common iliac arteries and the median sacral artery) For some reason, there are 3 suprarenal arteries. These supply the adrenal glands. The superior branch is derived from the inferior phrenic artery, the middle branch originates directly from the aorta, and the inferior branch comes off the renal artery.
