Summary
Ulnar artery aneurysms, often from blunt trauma, can cause digital ischemia. Prevention through industrial education is key to managing these traumatic arterial injuries.
Area of Science:
- Vascular Surgery
- Trauma Surgery
- Hand Surgery
Background:
- Ulnar artery aneurysms frequently result from blunt trauma to the hypothenar eminence.
- The superficial ulnar artery's proximity to the hook of the hamate predisposes it to injury.
Observation:
- Two cases of true ulnar artery aneurysms are presented, one from acute and one from chronic trauma.
- Both patients developed digital ischemia secondary to aneurysm thrombosis and adjacent arterial segment occlusion.
Findings:
- Thrombosis of the aneurysm and associated arterial segment correlated with the onset of ischemic symptoms.
- Digital artery embolization is a potential complication of the thrombotic event.
Implications:
- Surgical intervention can resolve ischemic symptoms.
- Industrial education is recommended for preventing traumatic ulnar artery aneurysms and subsequent hand ischemia.
