In the presence of celiac artery stenosis, flow can be diverted through what vessel? | Gastoduodenal artery |
Why is diagnosis of chronic mesenteric ischemia difficult? | Symptoms are rare and non-specific. Pt is often worked up for other potential problems such as gallbladder, malignancy, ulcers, etc. first. |
Lack of blood flow to the abdominal viscera | Mesenteric ischemia |
After eating | Postprandial |
What type of Doppler flow should be seen in the celiac, splenic, and hepatic arteries? | Low resistance |
When the pt is NPO, the SMA typically demonstrates what type of flow? | High resistance |
List the main branches of the abdominal aorta | Celic axis, SMA, renal arteries, IMA |
