Abdomen perfusion Flashcards
Diaphragm structures (I 8 10 EGGs AT 12) - “I ate 10 eggs at 12”
- at T8 - IVC
- at T10 - Esophagus, vagus
- at T12 - Aorta (descending),Azygous, thoracic duct
What is the first main branch after the descending aorta pierces through the aortic hiatus in the diaphragm?
celiac trunk
What are the three branches that come off the celiac trunk? 2 on the left and 1 on the right?
Right: Common hepatic artery
Left: Splenic artery
Left: left gastric artery
Where does the splenic artery perfuse to?
spleen
Where does the Left gastric artery perfuse to?
left aspect of the lesser curvature of the stomach
Where does the common hepatic artery go towards? and what does it branch into?
Liver.
Right gastric artery
Hepatic artery proper
Gastro-duodenal artery
Where does the Right gastric artery perfuse to? and what happens there?
right aspect of the lesser curvature of the stomach to anastemose with the left gastric artery
Where does the Left and right Gasto-omental arteries branch off from?
Left Gastro-omental= splenic artery
Right Gastro-omental= Gastroduodenial artery
Where dose the Right and Left gastro-omental arteries perfuse and how?
they anastamose at the Greater curvature of the stomach
How does the Hepatic artery proper branch further?
Right and Left hepatic artery
What does the right hepatic artery branch into?
ASAP a cystic artery branches off it
What is anastomose around the celiac trunk?
vagus nerve
Gastro-duodenial artery continues to where after branching the Right gastro-omental artery?
perfuses the duodenum
What is the second branch off the abdominal aorta after the celiac trunk?
superior mesonteric artery
What does mesontary mean?
the connective tissue found in between the intestines
What does superior mesonteric artery perfuse?
perfuses parts of the intestines:
all of the small intestines, ascending colon, and transverse colon
What branches off the abdominal aorta after the superior mesonteric artery, inferior to it?
Renal arteries
Where does the renal arteries go?
kidneys
What comes just inferior to the renal arteries?
gonadal arteries
testicular/ovarian
What does the gonadal arteries travel parallel with?
ureter
What comes after the gonadal arteries?
inferior mesonteric artery
What does the inferior mesonteric artery perfuse?
some of the transverse colon, descending colon, sigmoid colon, rectum
What level is the emergence of the descending aorta aka where diaphragm is?
T12
What level will the abdominal aorta bifricate?
L4
What does the abdominal aorta bifricate into at L4?
Right and Left common iliac arteries
What do each Common iliac arteries branch into?
Each have an external and internal iliac arteries
Where does the internal iliac arteries dive into and perfuse?
Dives into the pelvis
Sexual organs, some rectum, bladder
Where dose the internal iliac artery continue to after the pelvic region?
glueteal region, buttocks
Where does the external iliac arteries go towards?
Inguinal ligament
What branch does the external iliac give off before passing the inguinal ligament?
Inferior epigastric artery
Where is the inferior epigastric artery found in between?
posterior rectus sheath and rectus abdominus
What does the inferior epigastric and superior epigastric do?
Anastamose with each other in the abdominal region in between the layers of posterior rectus sheath and rectus abdominus muscle
Once the external iliac arteries pass the inguinal ligament what will occur?
It turns into femoral artery
What arteries perfuse the spinal cord?
anterior/posterior spinal arteries they are TINY
