Abdominal Vasculature - Part 3 Flashcards
GDA
Gastroduodenal artery
What does the GDA a branch of?
The common hepatic artery
What does the GDA lie between?
The superior portion of the duodenum and the anterior surface of the
pancreatic head
What does the common hepatic artery branch off of?
The celiac axis
What does the common hepatic artery give rise to?
GDA
What does the common hepatic artery name change to after it gives rise the the GDA?
Proper hepatic artery
Where does the hepatic artery course?
Adjacent to the portal vein
What does the proper hepatic artery bifurcate into? Where?
Bifurcates into the right and left hepatic arteries
At the hepatic hilum
What does the right hepatic artery give rise to?
Cystic artery
What does the cystic artery supply?
GB
What kind of resistance is in the hepatic artery?
Low-resistance blood flow
- with continuous flow through diastole
What is increased flow in the hepatic artery associated with? (3)
- Jaundice
- Cirrhosis, lymphoma
- Metastases
What does the left gastric artery a branch of?
Common hepatic artery
Where does the left gastric artery course?
Toward the left to supply the stomach
Where does the left gastric artery often originate from?
From the splenic artery
What does the splenic artery a branch of?
Celiac axis
What does the splenic artery give rise to?
The left gastroepiploic artery and additional branches to the pancreas
and stomach
Where does the splenic artery course?
Along the superior margin of the pancreatic body and tail
What kind of resistance is seen in the splenic artery?
Low-resistance blood flow
- with continuous flow through diastole
What can the splenic artery be mistaken for?
A dilated pancreatic duct
Where is the IVC formed?
At the junction of the right and left common iliac veins
What does the IVC carry?
Oxygen-depleted blood from the body superiorly to the right atrium of the heart
What are the major abdominal branches of the IVC? (6)
- Lumbar veins
- Right gonadal vein
- Renal veins
- Right suprarenal vein
- Inferior phrenic vein
- Hepatic veins
What are the main venous tributaries? (3)
- Common iliac veins
- Renal veins
- Hepatic veins
What does the common iliac veins drain?
Blood from the lower extremities and pelvis
Where is the common iliac veins formed?
At the junction of the external and internal iliac veins
Where does the renal veins course?
Anterior to the renal arteries
Where does the left renal vein course compared to the SMA and abdominal aorta?
Posterior to the superior mesenteric artery
Anterior to
the abdominal aorta
What kind of flow is demonstrated by the renal veins?
Spontaneous phasic blood flow
Where does the right hepatic vein course?
Coronally between the anterior and posterior segments of the right hepatic lobe
Where does the middle hepatic vein course?
Oblique course between the left and right hepatic
lobes
Where does the left hepatic vein course?
Posterior between the medial and lateral segments of the left hepatic lobe
What does doppler demonstrate in the hepatic veins?
Spontaneous, multiphasic, and pulsatile blood flow toward the IVC
- hepatofugal
What happens to the blood flow in the hepatic veins during inspiration?
Increase in blood flow
What happens to the blood flow in the hepatic veins during valsalva maneuver?
Diminished blood flow
