Duplex sonography effectively diagnoses pseudoaneurysms after arterial puncture, showing high sensitivity and specificity. It also offers value in postsurgical follow-up for selected patients.

Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging
  • Radiology

Background:

  • Peripheral pseudoaneurysms are a potential complication of arterial procedures.
  • Accurate diagnosis is crucial for effective management and patient outcomes.

Purpose of the Study:

  • To evaluate the diagnostic performance of duplex sonography for peripheral pseudoaneurysms.
  • To assess its utility in both acute post-puncture and post-surgical patient groups.

Main Methods:

  • Prospective review of 64 duplex sonographic examinations in 59 patients.
  • Patients were categorized into acute post-arterial puncture (Group 1) and post-vascular surgery (Group 2) cohorts.

Main Results:

  • Duplex sonography achieved 94% sensitivity and 97% specificity in Group 1.

  • In Group 2, it correctly identified pseudoaneurysms in 4/19 cases and excluded them in 6/19, with 9 cases indeterminate.

    • Conclusions:

    • Duplex sonography is recommended as a primary imaging modality for pseudoaneurysm diagnosis post-arterial puncture.
    • It can also serve as a valuable tool for selected postsurgical patient follow-up.
