Summary
This summary is machine-generated.

Vascular pseudoaneurysms, a frequent complication of arterial access, can be effectively treated with ultrasound-guided thrombin injection. This minimally invasive procedure offers a safe and rapid alternative to traditional treatments for arterial pseudoaneurysms.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Diagnostic Imaging

Background:

  • Vascular complications frequently arise from invasive procedures requiring arterial access.
  • Pseudoaneurysms are a common complication with risks of expansion, rupture, and infection.
  • Traditional treatments include surgical repair and compression, but new methods are emerging.

Purpose of the Study:

  • To evaluate ultrasound-guided thrombin injection as a primary treatment for arterial pseudoaneurysms.
  • To compare the efficacy and safety of this new method against existing treatments.

Main Methods:

  • Diagnosis relies on clinical suspicion and duplex ultrasonography.
  • Ultrasound-guided thrombin injection involves percutaneous insertion of a needle into the pseudoaneurysm sac.

  • A small amount of dilute bovine thrombin is injected under real-time visualization.

    • Main Results:

    • Ultrasound-guided thrombin injection is highly effective, rapid, and safe.
    • Rapid thrombosis of the pseudoaneurysm sac is observed.
    • Rare complications include thromboembolism and hypersensitivity reactions.

    Conclusions:

    • Ultrasound-guided thrombin injection is the preferred treatment for pseudoaneurysms.
    • This minimally invasive technique offers significant advantages in efficacy and safety.
    • Further research should monitor rare complications.
