Acute Digital Ischemia Associated with Closed Injury

Area of Science:

• Vascular Surgery
• Trauma Surgery
• Orthopedic Surgery

Background:

• Arterial injuries carry a worse prognosis than venous injuries.
• Acute ischemia in lower limb digital arteries due to blunt trauma is exceptionally rare.
• Understanding the mechanism of injury is crucial for patient outcomes.

Observation:

• A patient sustained a blunt injury to the right lower limb after an incorrect step.
• The injury involved a crush mechanism affecting the digital arteries.
• This resulted in acute acral ischemia of the right toes.

Findings:

• The injury mechanism involved a defect in the inner vessel surface due to the crush.
• Subsequent thromboischemic lesion developed, leading to acute ischemia.
• Digital artery injury in the lower limb is a critical finding.

Implications:

• This case underscores the potential severity of seemingly minor blunt trauma to lower limb arteries.
• Early recognition and management of acute acral ischemia are vital.
• Further research into blunt arterial trauma mechanisms may improve treatment strategies.
