Summary of article contents:

Introduction

The ulnar artery, a terminal branch of the brachial artery, plays a crucial role in supplying blood to the medial aspect of the forearm and hand. This study aims to explore the morphological characteristics and clinical implications of the ulnar artery based on observations from 68 upper limb specimens. Given its variability in origin and size, understanding these anatomical details is particularly vital for clinicians performing surgical procedures involving the arm, such as creating artificial arteriovenous (AV) fistulas for patients undergoing hemodialysis.

Morphological Characteristics

One key finding of the study is that the ulnar artery frequently arises distal to the superior margin of the head of the radius in approximately 82.65% of cases. The ulnar artery displays a consistent decrease in both internal and external diameters from proximal to distal regions across genders, with overall larger diameters observed in males compared to females. Additionally, the right ulnar artery generally has greater diameters and wall thickness compared to the left, making it a preferable choice for surgical access points for hemodialysis procedures. The varying angles of origin with respect to the brachial artery were also documented, underscoring the anatomical variability that surgeons must consider.

Conclusion

The comprehensive data collected in this study offer critical insight into the anatomy of the ulnar artery, which is essential for minimizing iatrogenic complications during surgical interventions. With its larger diameter, particularly in the right ulnar artery, there is a strong case for its usage in artificial AV fistulas. This anatomical knowledge can significantly improve surgical planning and patient outcomes for those requiring hemodialysis, highlighting the need for radiologists to assess arterial dimensions preoperatively to inform surgical strategies effectively.

FAQ section (important questions/answers):

What is the main objective of this study on the ulnar artery?

The study aims to provide comprehensive morphological data concerning the ulnar artery, focusing on its measurements and clinical implications for surgical applications, especially in creating artificial arteriovenous fistulas for patients with end-stage renal disease.

What measurements were taken from the ulnar artery specimens?

Measurements included the internal diameter, external diameter, wall thickness, and the angle degree of the ulnar artery origin in relation to the brachial artery from 68 dissected upper limb specimens.

How did the ulnar artery characteristics differ between genders?

The study found that the external and internal diameters of the ulnar artery were generally larger in males compared to females. Additionally, right ulnar artery measurements were consistently larger than those of the left in both genders.

What is the recommended use of the ulnar artery in surgeries?

Due to its size, the right ulnar artery is deemed suitable for creating artificial arteriovenous fistulas for hemodialysis, particularly when radial or brachial arteries are unavailable, thereby providing easier access for surgeons.
