The document summarizes the branches of the abdominal aorta. It describes the celiac trunk, superior mesenteric artery, and inferior mesenteric artery as the three anterior branches that arise from the abdominal aorta and supply the gastrointestinal viscera. The celiac trunk divides into the left gastric artery, splenic artery, and common hepatic artery. The superior mesenteric artery has five branches including the inferior pancreaticoduodenal artery and jejunal/ileal arteries. The inferior mesenteric artery has three branches including the left colic artery and sigmoid arteries.

2. ABDOMINAL AORTA
• IT BEGINS AT THE AORTIC
HIATUS OF THE DIAPHRAGM,
ANTERIOR TO THE LOWER
BORDER OF VERTEBRA T7.
• IT DESCENDS TO THE LEVEL OF
VERTEBRA L4 IT IS SLIGHTLY TO
THE LEFT OF MIDLINE.
• THE TERMINAL BRANCHES OF
THE ABDOMINAL AORTA ARE THE
TWO COMMON ILIAC ARTERIES. 2

6. CELIAC TRUNK
• IT ARISES FROM THE ABDOMINAL
AORTA IMMEDIATELY BELOW THE
AORTIC HIATUS OF THE
DIAPHRAGM ANTERIOR TO THE
UPPER PART OF VERTEBRA L I .
• IT DIVIDES INTO THE:
• LEFT GASTRIC ARTERY,
• SPLENIC ARTERY,
• COMMON HEPATIC ARTERY.

9. SUPERIOR MESENTERIC ARTERY
• IT ARISES FROM THE ABDOMINAL
AORTA IMMEDIATELY 1CM BELOW THE
CELIAC ARTERY ANTERIOR TO THE
LOWER PART OF VERTEBRA LI.
• IT IS CROSSED ANTERIORLY BY THE
SPLENIC VEIN AND THE NECK OF
PANCREAS.
• POSTERIOR TO THE ARTERY ARE THE
LEFT RENAL VEIN, THE UNCINATE
PROCESS OF THE PANCREAS, AND THE
INFERIOR PART OF THE DUODENUM.

10. ANASTOMOSES AND HAS FIVE BRANCHES
• INFERIOR PANCREATICODUODENAL ARTERU
• JEJUNAL AND ILEAL ARTERIES
• ILEOCOLIC ARTERIES
• RIGHT COLIC ARTERY
• MIDDLE COLIC ARTERY

12. INFERIOR MESENTERIC ARTERY
• IT IS THE SMALLEST OF THE THREE
ANTERIOR BRANCHES OF THE
ABDOMINAL AORTA AND ARISES
ANTERIOR TO THE BODY OF VERTEBRA
L3.
• INITIALLY, THE INFERIOR MESENTERIC
ARTERY DESCENDS ANTERIORLY TO THE
AORTA AND THEN PASSES TO THE LEFT
AS IT CONTINUES INFERIORLY.

13. ANASTOMOSES AND HAS THREE BRANCHES
• LEFT COLIC ARTERY
• SIGMOID ARTERIES
• SUPERIOR RECTAL ARTERY
