Summary
This study details variations in upper abdominal artery formation and location using 75 visceral complexes. It presents a novel hepatic artery variant and two laws explaining arterial arrangement in the upper abdomen.
Area of Science:
- Vascular anatomy
- Surgical anatomy
Context:
- Understanding the anatomical variations of the upper abdominal arteries is crucial for surgical planning and interpretation of diagnostic imaging.
- Previous studies have described various arterial patterns, but a comprehensive understanding of their arrangement and governing principles remains incomplete.
Purpose:
- To investigate and document the diverse anatomical variants of the arteries supplying the upper abdomen.
- To describe the specific location and characteristics of these arterial variants.
- To formulate generalizable laws governing the arrangement of the right and left hepatic arteries.
Summary:
- The study analyzed 75 visceral complexes to meticulously document variations in the formation and spatial arrangement of upper abdominal arteries.
- A unique variant of the hepatic artery was identified and described.
- Two fundamental laws were formulated that accurately predict the predominant positioning of the right and left hepatic arteries across all known anatomical configurations.
Impact:
- Provides a detailed anatomical reference for surgeons performing procedures in the upper abdomen, potentially reducing intraoperative complications.
- Enhances the accuracy of interpreting radiological images by accounting for common and rare arterial variations.
- Contributes to a deeper understanding of embryological and developmental processes influencing vascular patterning in the upper abdomen.
