Key for Posterior Abdominal Wall, Kidneys, and Abdominal Vasculature - September 17, 2006

• 21. Esophageal artery
  • branching off left gastric artery
    
• 22. short gastric artery
  • within the gastroleino ligament
    
• 23. ligamentum venosum
  • showing attachement of gastrohepatic ligament
    
• 24. gastroduodenal artery or right gastroepiploic artery
  • shown crossing posterior to duodenal cap
    
• 25. superior posterior pancreaticoduodenal artery
  • distinguished from anterior pancreaticoduodenal by relationship to head of pancreas
  • retroduodenal aa are visible nearby
    
• 26. L. gastroepiploic artery
  • continuation of the splenic artery
    
• 27. L. colic artery
  • branch of inferior mesenteric artery
    
• 28. sigmoidal artery
  • shown going to peritonealized sigmoid colon
    
• 29. inferior mesenteric plexus
  • fibrous tissue on inferior mesenteric artery
    
• 30. superior rectal artery or inferior mesenteric artery
  
  • continuation of inferior mesenteric artery
    
• 31. ligamentum teres (liver)
  • fibrous cord within falciform ligament
  • at inferior free edge of ventral mesentery
    
• 32. anterior lamina coronary ligament (R.)
  • anterior boundary of bare area of liver
    
• 33. L. triangular ligament
  • lateral left extension of coronary ligament
    
• 34. anterior vagal trunk
  • shown on anterior esophageal surface
  • esophageal artery was shown
    
• 35. L. gastric artery
  • Was this the esophageal artery?
    
• 36. R. Colic artery
  • branch of the iliocolic artery
    
• 37. middle colic artery or R. colic artery....( dont worry bout it...unusual anatomy)
  • middle colic is perhaps the best call based on parent artery - SMA
    
• 38. marginal artery of drummond
  • Continuation of middle colic at this location but well distal along the margin of the transverse colon
    
• 39. illo br. of the illiocolic artery
  • shown heading proximally along the ileum
    
• 40. falciform ligament
  • remnant of the ventral mesentery
  • stabilizes liver to anterior abdominal wall
    
• 41. lumbar artery
  • orthogonal and deep to lumbar sympathetic trunk
• 42. lumbar sympathetic trunk
  • lumbar splanchnic
  • ramus communicans (gray)
• 43. genitofemoral n.
  • psoas major
• 44. lumbar splanchnic nerve
  • branches from anterior aspect of lumbar sympathetic trunk and proceeds anterior, inferior, and medial toward the aortic plexus
    
• 45. ramus communicans (gray)
  • posterior branch from the lumbar sympathetic trunk
  • shown coursing posterior toward lumbar plexus
  • communicates between lumbar sympathetic trunk and lumbar spinal nerve
