Vascular trauma in extremities risks amputation, but early diagnosis via Doppler and duplex sonography aids treatment. Prompt surgery for critical ischemia or hemorrhage significantly improves outcomes and reduces amputation risk.

Area of Science:

  • Trauma Surgery
  • Vascular Surgery
  • Emergency Medicine

Background:

  • Vascular injuries of the extremities represent the majority of vascular trauma cases, carrying a significant risk of amputation (10-20%).
  • Arterial trauma is categorized as direct or indirect based on the causative force, influencing hemorrhage and ischemia severity.

Purpose of the Study:

  • To review diagnostic and treatment strategies for vascular injuries of the extremities.
  • To highlight factors influencing amputation risk in vascular trauma patients.

Main Methods:

  • Review of diagnostic modalities including clinical examination, ankle-brachial (AB) or wrist-brachial (WB) index, Doppler sonography, duplex sonography, and angiography.
  • Discussion of surgical indications and timing based on injury severity and patient condition.

Related Experiment Videos

  • Identification of risk factors for amputation following vascular reconstruction.

    • Main Results:

    • Clinical examination and an AB or WB index >1.0 can reliably exclude treatable vascular injury.
    • Doppler and duplex sonography are valuable for early diagnosis in patients with multiple injuries.
    • Immediate surgery is indicated for critical ischemia, squirting hemorrhage, or rapidly expanding hematoma.

    Conclusions:

    • Timely diagnosis and appropriate management, guided by imaging and clinical assessment, are crucial for limb salvage in vascular trauma.
    • Factors such as arterial occlusion post-reconstruction, compartment syndrome, and inadequate anticoagulation increase amputation risk.
