Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta. If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
The abdominal aorta's venous counterpart, the inferior vena cava (IVC), travels parallel to it on its right side. Above the level of the umbilicus, the aorta is somewhat posterior to the IVC, sending the right renal artery travelling behind it. The IVC likewise sends its opposite side counterpart, the left renal vein, crossing in front of the ...
The IMA arises from the anterior aspect of the abdominal aorta. [2] [3]Its origin is situated at the L3 vertebral level, [2] [3] below the origins of the two renal arteries, [3] 3-4 cm above the aortic bifurcation, [3] [2] at the level of the umbilicus, and posterior to the inferior border of the horizontal (III) part of the duodenum.
[4] [5] This may cause abdominal pain. [5] The celiac artery is vulnerable to compression from the crus of the diaphragm during ventilation where it originates from the abdominal aorta. [1] This is known as median arcuate ligament syndrome. [6] This may present no symptoms, but can cause pain due to restricted blood flow to the superior ...
In human anatomy, the superior epigastric artery is a terminal [1] branch of the internal thoracic artery that provides arterial supply to the abdominal wall, and upper rectus abdominis muscle. It enters the rectus sheath to descend upon the inner surface of the rectus abdominis muscle. It ends by anastomosing with the inferior epigastric artery.
Superior mesenteric artery compressing the duodenum, featuring the superior mesenteric artery syndrome. Superior mesenteric artery (SMA) syndrome is a gastro-vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta (AA) and the overlying superior mesenteric artery.
Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.
Abdominal aortic aneurysm involves a regional dilation of the aorta and is diagnosed using ultrasonography, computed tomography, or magnetic resonance imaging. A segment of the aorta that is found to be greater than 50% larger than that of a healthy individual of the same sex and age is considered aneurysmal. [ 9 ]
