Receives dual blood supplies

Duodenum (celiac trunk) and transverse colon (superior & inferior mesenteric arteries)

1

Celiac Trunk origin

T12

2

Superior Mesenteric Artery Origin

L1

3

Inferior Mesenteric Artery Origin

L3

4

Celiac Trunk branches

1. Left Gastric

2. Splenic => short gastric & left gastroepiploi

3. Common Hepatic
(a.) => gastroduodenal => supraduodenal OR superior pancreaticoduodenal and right gastroepiploic

(b). proper hepatic => right gastric OR R/L hepatic and cystic

5

Branches of Superior Mesenteric Artery

1. Inferior pancreaticoduodenal
2. Intestinal Branches
3. Middle colic
4. Right colic
5. Ileocolic

6

Branches of Inferior Mesenteric Artery

1. Left colic
2. Sigmoid branches
3. Superior rectal`

7

G.I. Arterial Anastomoses

Superior and inferior pancreaticoduodenal arteries and the colic flexture thru the Marginal Artery of Drummond

8

Portal Vein

Formed by the jnxn of the splenic and superior mesenteric veins

*Inferior mesenteric feed into one of these two

9

Portal-Caval Anastomoses

Esophagus: Left gastric (Portal) and esophageal (caval)
*Esophageal varices w/ fatal hemorrhage

Umbilicus: Paraumbilcal (portal) and superficial epigastric (caval)
*Caput medusae

Rectum: Superior rectal (portal) and inferior rectal (caval)
*Internal hemorrhoids

Posterior Abdominal Wall: Colic veins (portal) and retroperitoneal veins
*NONE

10

Lymph Drainage of Abdominal Wall

Superior to umbilicus => Anterior/posterior axillary nodes

Inferior to umbilicus => Superficial inguinal nodes

11

Testes and scrotum/labia lymphatic drainage

Testis => Para-aortic (lumbar) nodes

Scrotum/Labia majora => Superficial inguinal nodes

12

G.I. Tract lymphatic drainage

Drain to pre-aortic nodes (around the main arteries supplying the area) and then to the cisterna chyli

13

Anal canal lymphatic drainage

Superior to the pectinate line => Inferior mesenteric nodes

Inferior to the pectinate line => Superficial inguinal nodes

14

Artery found in gastrosplenic ligament

Left gastroepiploic artery

15

Intestines born on outside of neonate body and covered in NOTHING

Gastroschisis
