Pseudoaneurysms, often from external fixator pin/wire placement, commonly present with bleeding. Prompt diagnosis and varied surgical or embolisation techniques are crucial for managing these vascular complications.

Area of Science:

  • Vascular Surgery
  • Orthopaedic Surgery
  • Radiology

Background:

  • Pseudoaneurysms are a rare but serious complication following orthopaedic procedures.
  • External fixators, while essential for complex fractures, carry risks associated with pin/wire insertion.
  • Penetrating injuries near major vessels necessitate vigilance for vascular damage.

Purpose of the Study:

  • To report on the incidence, presentation, and management of pseudoaneurysms.
  • To highlight the role of external fixators in pseudoaneurysm formation.
  • To emphasize diagnostic and therapeutic strategies for pseudoaneurysms.

Main Methods:

  • Retrospective review of thirteen pseudoaneurysm cases.
  • Pre-operative imaging including radiography, arteriography, Doppler, and CT angiography.

  • Surgical interventions such as ligation, resection, grafting, and embolisation.

    • Main Results:

    • Five of thirteen pseudoaneurysms resulted from external fixator pin/wire placement.
    • Profuse bleeding was the most common presenting symptom.
    • Fractures or fracture stabilization directly caused nine pseudoaneurysms.

    Conclusions:

    • A high index of suspicion is vital for diagnosing pseudoaneurysms after penetrating injuries or external fixator use.
    • Effective management requires a combination of advanced imaging and tailored surgical or interventional techniques.
    • Injudicious external fixator use can lead to life/limb-threatening vascular complications.
