Summary
This summary is machine-generated.This study clarifies the superior epigastric artery's (SEA) anatomical course, correcting textbook errors. Dissections confirm the SEA consistently runs ventral to the diaphragm, not through Larrey's fissure.
Area Of Science
- Anatomical studies
- Surgical anatomy
- Medical education
Background
- A discrepancy exists between the superior epigastric artery (SEA) observed in human dissections and its portrayal in German-language anatomy textbooks.
- Textbooks often incorrectly depict the SEA traversing the sternocostal triangle (Larrey's fissure), contrary to its typical ventral course relative to the diaphragm.
Purpose Of The Study
- To investigate and resolve the anatomical inaccuracy in textbook descriptions of the superior epigastric artery's (SEA) pathway.
- To provide accurate topographical information on the SEA's course through anatomical dissection and historical literature analysis.
Main Methods
- Conducted anatomical dissections on 40 formalin-fixed human donors.
- Systematically dissected thoracic and abdominal walls to document the SEA's course.
- Analyzed historical anatomical literature to trace the origin of the misrepresentation.
Main Results
- In all 40 specimens, the superior epigastric artery (SEA) was observed to run ventral to the pleural and peritoneal cavities.
- The SEA did not traverse the sternocostal triangle (Larrey's space) in any of the dissected specimens.
- Historical analysis identified a chain of misreadings originating in the 19th century as the source of the persistent inaccuracy.
Conclusions
- The traditional textbook depiction of the superior epigastric artery (SEA) passing through Larrey's space is anatomically incorrect.
- Accurate anatomical representation of the SEA's topographical relationships is crucial and necessitates revision of historical anatomical literature.
- This study highlights the importance of verifying anatomical descriptions against empirical dissection findings.

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...
Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...
