Summary
We present two cases of aberrant right subclavian artery aneurysms, a rare condition. Surgical removal is recommended for growing aneurysms to prevent rupture, with CT being the preferred imaging method.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Cardiovascular Medicine
Background:
- Aberrant right subclavian artery (ARSA) is a rare congenital anomaly.
- Aneurysms arising from an ARSA are exceptionally uncommon, posing diagnostic and therapeutic challenges.
- Understanding the imaging characteristics and natural history is crucial for management.
Observation:
- Two cases of ARSA aneurysm are presented.
- Detailed review of imaging findings, diagnostic criteria, and evolution patterns.
- Computed Tomography (CT) demonstrated superior utility in aneurysm assessment.
Findings:
- ARSA aneurysms require careful evaluation due to their rarity.
- CT imaging provides comprehensive anatomical and pathological details.
- Growth patterns indicate a higher risk of complications.
Implications:
- Early diagnosis and intervention are key to preventing catastrophic rupture.
- Surgical intervention should be considered for growing ARSA aneurysms when feasible.
- This case series contributes to the limited literature on ARSA aneurysm management.
