Test 3 Anatomy review
| Question | Answer |
|---|---|
| What do you evaluate with Abdominal Doppler? | Abdominal AO, Mesenteric arts (celiac axis, Hepatic A, Splentic A, SMA), Renal As & Vs, Portal venous system (Portal Vs, SMV, & Splenic V), IVC, and Hepatic Vs |
| Reasons for eval and Doppler interrogation for Abdominal Doppler? | Aneurysm, Arterial stenosis, Ischemia, HTN, Thrombsis, Budd-Chiari syndrome, TIPS eval, Graft eval, Transplant eval |
| What TD do you need for abdominal scanning? | 2-5 MHz TD curved |
| What do you not do to the spectral waveform or color flow in abdominal doppler studies? | DO NOT INVERT spectral waveforms or color flow |
| Where does the Abdominal AO begin? | Begins at the level of the 12th thoracic vertebra (passes through the aortic hiatus) |
| Celiac Artery facts: | AKA Celiac trunk, Celiac axis, First major anterior branch of aorta, Gives rise to Hepatic, Splenic and Left Gastric Arteries |
| Superior Mesenteric Artery facts: | Next anterior branch of the aorta, Arises just below the celiac artery, Supplies most of the small intestine and some large intestine |
| Inferior Mesenteric Artery Facts: | Last anterior branch of Aorta, Arises 3-4 cm above aortic bifurcation, Mainly supplies the large intestines |
| Renal Artery facts: | Lateral branches of Ao, Arise just below the SMA, Right Renal A is longer & slightly thinner than Left, Right Renal A courses posterior to the IVC, Both Renal arts approach kidney posterior to renal veins |
| What are the Renal Vasculature Arteries? | Main renal artery (@ hilum), Segmental renal artery (renal sinus), Interlobar arteries, Arcurate arteries (renal cortex), interlobular arteries |
| What are the vessels of the Abdomen- arteries? | Testicular/Ovarian As (anterolateral branches of the Ao, Arise just below the renal As), Lumbar As (arise posteriorly off the Ao), Middle sacral artery (single A arising off the posterior Ao, Arise just above the aortic bifurcation) |
| IVC facts: | Courses through abdomen to the right of the Ao |
| What are the IVC major tributaries? | Renal Vs (R&L), Hepatic Vs (R,M, &L), Lumbar Vs, Ovarian/Testicular Vs |
| Where does the left Ovarian/Testicular V typically drain? | Into left renal vein |
| Hepatic A carries what? | Oxygenated blood into the liver, Carries 30% of total blood flow into the liver |
| Portal V carries what? | Remaining 70% of blood, Formed at junction of splenic& SMVs, Begins posterior to the neck of the pancreas and anterior to IVC |
| Hepatic Vs (right, middle & left) does what? | Drain from liver into IVC |
