Receives dual blood supplies
Duodenum (celiac trunk) and transverse colon (superior & inferior mesenteric arteries)

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
