What is the aortic bifurcation?
The aortic bifurcation is the point at which the abdominal aorta bifurcates into the left and right common iliac arteries. The aortic bifurcation is usually seen at the level of L4, just above the junction of the left and right common iliac veins.
What causes aortic bifurcation?
The aortic bifurcation is the point at which the abdominal aorta bifurcates (forks) into the left and right common iliac arteries….

Where is the bifurcation of the abdominal aorta located?
L4 level
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.
How does the aortic bifurcation lie in relation to the umbilicus in the Cryosection?
Conclusions: The umbilicus is often located at or cephalad to the aortic bifurcation, and consistently located cephalad to where the left common iliac vein crosses the midline. The laparoscopic approach should take these relationships into account to minimize injuries to major retroperitoneal vessels.
What level is aortic bifurcation?
L4 vertebra
The aortic bifurcation mostly found at the level of L4 vertebra in the present study similar to previous studies. The aortic bifurcation can be a reliable landmark for determining the lumbar vertebral segments on MRI or CT.
Which artery supply the blood to the heart?
Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function.
At what level does the common iliac artery bifurcation?
The common iliac arteries are two large arteries that originate from the aortic bifurcation at the level of the fourth lumbar vertebra. They end in front of the sacroiliac joint, one on either side, and each bifurcates into the external and internal iliac arteries.
How many branches does the aorta have?
three branches
The arch of the aorta has three branches: the brachiocephalic artery (which divides into right common carotid artery and the right subclavian artery), the left common carotid artery, and the left subclavian artery. These arteries provide blood to both arms and the head.
What are the 3 arteries coming off the aortic arch?
The three main branches of the aortic arch are the brachiocephalic (innominate) artery (dividing into the right subclavian and common carotid arteries), the left common carotid artery, and the left subclavian artery.
At what level does the common iliac artery bifurcate?
fourth lumbar vertebra
Volume rendered CT scan of abdominal and pelvic blood vessels. The common iliac arteries are two large arteries that originate from the aortic bifurcation at the level of the fourth lumbar vertebra.
Which artery supplies blood to the organs in the pelvic cavity?
internal iliac artery
The external iliac artery supplies the lower limb and internal iliac artery is the major vascular supply of the pelvis(1). The internal iliac artery is one of the two divided parts of the common iliac artery, it passes medially over the pelvic brim and runs downward to the pelvic cavity.
How many arteries go to your heart?
There are two main coronary arteries – the left main coronary artery and the right coronary artery. The left main coronary artery divides into two branches called the left anterior descending (LAD) artery and the left circumflex artery.
Where does the bifurcation of the aorta take place?
The aortic bifurcation is the point at which the abdominal aorta bifurcates (forks) into the left and right common iliac arteries.
How big is the aortic bifurcation in CTA?
A computerized tomography angiogram (CTA) scan demonstrated a 6.5 cm Crawford type III TAAA extending from the midthoracic aorta to the aortic bifurcation with no evidence of any leak.
What kind of aortic bifurcation is Leriche syndrome?
Leriche syndrome refers to occlusion of the abdominal aorta distal to the renal arteries, aortic bifurcation and the common iliac arteries being usually involved. There was an aortic transection at the abdominal aortic bifurcation extending to the right common iliac artery (Fig. Disease may then spread downwards towards the aortic bifurcation.
What kind of stent is used for aortic bifurcation?
The device measures the time interval between the peaks of the direct (first) and reflected (late) systolic wave (return time). Two balloon expandable (BE) covered stents (Bentley Innomed GmbH, Germany, 10 x 57 mm (right side) and 9 x 57 mm (left side)) were initially advanced and deployed at aortic bifurcation.
