Summary
This summary is machine-generated.

The supraduodenal artery was present in 28 of 30 specimens, typically originating from the gastroduodenal artery. This artery consistently supplied the duodenum and common bile duct, with frequent anastomoses.

Area of Science:

  • Anatomical studies
  • Surgical anatomy
  • Vascular anatomy

Background:

  • The supraduodenal artery is a significant anatomical structure in the upper abdomen.
  • Understanding its variations and origins is crucial for surgical procedures in the hepatobiliary and duodenal regions.

Purpose of the Study:

  • To investigate the prevalence and anatomical course of the supraduodenal artery.
  • To identify the common origins and distribution patterns of the supraduodenal artery.
  • To document its anastomoses with adjacent arteries.

Main Methods:

  • Dissection and macroscopic examination of 30 human cadaveric specimens.
  • Detailed analysis of the supraduodenal artery's origin, course, and distribution.
  • Documentation of its relationship with the gastroduodenal artery, right gastric artery, and pancreaticoduodenal arteries.

Main Results:

  • The supraduodenal artery was identified in 28 out of 30 specimens (93.3%).
  • The most frequent origin was the gastroduodenal artery (26 cases), with two instances arising from the pericholedochal plexus.
  • Consistent distribution to the distal two-thirds of the superior duodenum, extending to supra- and retroduodenal common bile duct portions was observed. Anastomoses with the right gastric artery and posterior superior pancreaticoduodenal artery occurred in approximately half the cases.

Conclusions:

  • The supraduodenal artery is a consistently present vessel with a predominant origin from the gastroduodenal artery.
  • Its consistent vascularization of the duodenum and common bile duct highlights its importance in surgical planning.
  • Variations in origin and frequent anastomoses underscore the need for detailed preoperative anatomical assessment.
