Summary
This summary is machine-generated.

Hypothenar Hammer Syndrome (HHS), a rare hand injury, can cause ulnar artery aneurysms. Surgical ligation of the ulnar artery effectively treated this condition, preventing further complications.

Area of Science:

  • Vascular Surgery
  • Hand Surgery
  • Occupational Medicine

Background:

  • Hypothenar Hammer Syndrome (HHS) is an uncommon vascular injury typically affecting the dominant hand.
  • It results from repetitive trauma to the hypothenar eminence, often seen in individuals with specific occupational or recreational activities.
  • This case highlights HHS associated with Raynaud's phenomenon.

Observation:

  • A middle-aged male presented with symptoms consistent with HHS.
  • Diagnostic imaging, including ultrasound duplex and color scanning, identified an aneurysm with thrombosis in the ulnar artery near the hamate bone.
  • The patient also exhibited Raynaud's phenomenon.

Findings:

  • The ultrasound findings confirmed a pseudoaneurysm of the ulnar artery.

Related Experiment Videos

  • The aneurysm was thrombosed, indicating a blockage within the abnormal vessel.
  • The location was adjacent to the hook of the hamate, a common site for such injuries.

    • Implications:

    • Surgical ligation of the affected ulnar artery was performed as a treatment.
    • This intervention successfully eliminated blood flow to the pseudoaneurysm.
    • The procedure prevented further microembolisation to the fingers, resolving the patient's symptoms.
