Superficial ulnar artery pseudoaneurysm

Area of Science:

• Anatomy
• Vascular Surgery
• Radiology

Background:

• The ulnar artery, a major forearm vessel, typically lies deep within the flexor muscles.
• Anatomical variations in vascular structures can impact surgical and diagnostic procedures.
• Understanding arterial anatomy is crucial for preventing iatrogenic injuries.

Purpose of the Study:

• To report a rare anatomical variant of the superficial ulnar artery.
• To highlight the potential for misidentification and injury during medical interventions.
• To emphasize the importance of pre-procedural anatomical assessment.

Main Methods:

• Case report detailing an anatomical finding during a medical procedure.
• Review of anatomical literature regarding ulnar artery variations.
• Discussion of the clinical implications of the observed variant.

Main Results:

• A case of an ulnar artery located superficially in the forearm was identified.
• The superficial location of the artery was not recognized prior to an attempted venous puncture.
• This led to an accidental arterial injury and the subsequent formation of a pseudoaneurysm.

Conclusions:

• Superficial ulnar artery is a rare variant that poses a risk for iatrogenic injury.
• Awareness of such anatomical variations is essential for clinicians performing procedures in the forearm.
• Diagnostic imaging may be beneficial in cases with atypical superficial vessel presentation.
