Chp 9 Abd Vasculature - Penny
Patient with history of back pain & hypertension you visualize a 6 cm infrarenal aortic aneurysm with echogenic linear structure noted gently swaying in the Aortic lumen what is the diagnosis most likely
Aortic dissection
Which vessel travels anterior to the left renal artery
Left renal vein
Aorta originates at the
Left ventricle
They hepatic artery should demonstrate what flow
Low resistance flow
Clinical findings of an abdominal aortic aneurysm include
Lower extremity pain back pain and abdominal bruit
The diameter of the IVC Should never exceed
2.5 cm
And abdominal aortic aneurysm is present when the diameter of the abdominal aorta exceeds
3 cm
Occlusion of the hepatic v describes
Budd-Chiari syndrome
First main visceral branch of the abdominal aorta
Celiac artery
Which artery would most likely have a high resistance flow pattern Celiac, common iliac, splenic or right renal
Common iliac a.
Most common shape of an abdominal aortic aneurysm is
Fusiform
Branches of the celiac access
Hepatic splenic and left gastric artery
Veins seen attaching to the IVC just below the diaphragm are
Hepatic v
Which of the following would have a pulsatile triphasic blood flow pattern Renal hepatic Gonadal or common iliac veins
Hepatic veins because of their location near to the heart
Vessel traveling posterior to the superior mesenteric artery and anterior to the abdominal aorta
Left renal vein
What should the postprandial flow pattern be within the superior mesenteric artery
Low resistance
And aneurysm associated with infection is
Mycotic
IVC terminates at
Right atrium to the heart
Which vessel would be the shortest in length Right renal vein right renal artery left renal vein or left renal artery
Right renal vein
Enlargement of the IVC with subsequent enlargement of the hepatic veins is seen in cases of
Right-sided heart failure
Vascular structure that may be confused for the main pancreatic duct
Splenic artery
The main portal vein is created by the union
Splenic vein and superior mesenteric vein
Which vessel will show a different flow pattern after eating
Superior mesenteric artery
Outer layer of the vessel
Tunica adventitia
What is the inner wall layer of the vessel closest of the passing blood called
Tunica intima
True statements about the abdominal aorta
Abdominal aorta is located just left of the midline the most common location of an abdominal aortic aneurysm is infrarenal abdominal aorta is considered to be retroperitoneal and most abd aneurysms located within the abdominal aorta are true aneurysms
In small bowel ischemia the postprandial superior mesenteric artery will yield what flow pattern
High resistance
The second main branch of the abdominal aorta is
Superior mesenteric artery
What is true about the IVC
The diameter is variable respiration can affect the size and is considered a retroperitoneal location it is located to the right of the abdominal aorta
Name The structures seen in a transverse view of the abdominal aorta at the level of the SMA
The liver pancreas portal confluence SMA splenic vein aorta IVC and vertebrae
