Abstract:
Vertebral artery pseudoaneurysm (VAP) is the result of the penetrating neck trauma, chiropractic manipulation, vasculopathies and rarely iatrogenic due to internal jugular vein (IJV) catheterization. It should be identified and treated immediately because of its potential risk of rupture. We present a case of a right VAP resulting from jugular vein catheterization, with the Doppler ultrasonography (US), Computed tomography (CT) and magnetic resonance imaging (MRI) findings. Although angiography is a well known gold standard modality, Doppler US, CT and MRI findings can be sufficient to demonstrate VAP.
Insights
Vertebral artery pseudoaneurysm (VAP) can arise from neck trauma or medical procedures. Imaging like Doppler US, CT, and MRI can effectively diagnose VAP, enabling prompt treatment to prevent rupture.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Interventional Radiology
Background:
- Vertebral artery pseudoaneurysm (VAP) is a rare but serious condition.
- Causes include trauma, chiropractic manipulation, vasculopathies, and iatrogenic injury from internal jugular vein catheterization.
- VAP requires immediate identification and treatment due to rupture risk.
Observation:
- This report details a case of right VAP.
- The VAP was a consequence of internal jugular vein catheterization.
- Diagnostic imaging included Doppler ultrasonography (US), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI).
Findings:
- Doppler US, CT, and MRI provided sufficient evidence to demonstrate the VAP.
- These non-invasive modalities were effective in visualizing the pseudoaneurysm.
- Findings correlated with the clinical presentation and suspected etiology.
Implications:
- Non-invasive imaging techniques are valuable for diagnosing VAP.
- Early diagnosis via Doppler US, CT, and MRI can facilitate timely intervention.
- This case highlights the importance of considering VAP after procedures like IJV catheterization.
