Study Notes
Abdominal Aorta Branching Level
- Branches at the 1st lumbar vertebra, inferior to the SMA, at the umbilicus.
Low Resistance Vessel Supply
- Supplies organs requiring constant blood perfusion.
Hepatic Vein Drainage Image
- Transverse image: "Playboy bunny" or "reindeer" sign.
Portal Vein Formation
- Formed by the confluence of the splenic vein and the superior mesenteric vein (SMV).
Hepatic Artery Origin
- Arises from the celiac trunk, passes anterior to the portal vein, and enters the liver at the porta hepatis.
Hepatofugal Flow
- Flow away from the liver.
Hepatopetal Flow
- Flow toward the liver.
Normal Portal Vein Flow
- Hepatopetal.
Portal Vein Hypertension Effect on Flow
- Causes hepatofugal flow.
Inferior Mesenteric Artery Supply
- Supplies the left transverse colon, descending colon, sigmoid colon, and rectum.
Superior Mesenteric Artery Supply
- Supplies the proximal half of the colon and small intestine.
Doppler Functionality
- Detects flow presence/absence, direction, disturbances, and tissue characteristics.
SMA Position in Sagittal Plane
- Passes posterior to the neck of the pancreas and anterior to the uncinate process.
Vessel Position Between Aorta and SMA
- Left renal vein.
Aortic Aneurysm Risk Factors
- Known vascular disease, age over 60, hypertension, smoking.
Aortic Aneurysm Predisposing Factors
- Arteriosclerosis (most common), syphilis, trauma.
Aneurysm Definition
- Permanent, localized dilation of an artery.
Aneurysm Qualifying Measurement
- 1.5 times greater than the normal aorta diameter (3 cm).
Aneurysm Types
- Fusiform and saccular.
