Pseudoaneurysms: Different ultrasound patterns, aetiologies and locations

Area of Science:

• Vascular Surgery
• Diagnostic Imaging
• Radiology

Background:

• Pseudoaneurysms (PSAs) are frequent vascular anomalies.
• Understanding their diverse etiologies and presentations is crucial for effective management.

Purpose of the Study:

• To review the diagnostic features of pseudoaneurysms (PSAs) across various imaging modalities.
• To consolidate information on PSA etiologies, locations, and complications to aid clinical decision-making.

Main Methods:

• Review of diagnostic modalities including colour Doppler ultrasound, computed tomographic angiography, magnetic resonance angiography, and conventional angiography.
• Case series illustration.

Main Results:

• Specific imaging findings characteristic of pseudoaneurysms (PSAs) are described for each modality.
• Common etiologies (iatrogenic, traumatic, dissecting, anastomotic), locations, and potential complications are outlined.

Conclusions:

• Accurate diagnosis of pseudoaneurysms (PSAs) relies on recognizing specific imaging features.
• Knowledge of etiology, location, and complications is essential for optimal treatment selection.
