Aberrant subclavian artery (ASA) aneurysms are rare but life-threatening. Surgical intervention is often indicated, though conservative management may be suitable for select patients, as demonstrated in this case series.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Anomalies
  • Congenital Heart Disease

Background:

  • Aberrant subclavian artery (ASA) is the most common congenital anomaly of the aortic arch.
  • Aneurysms of the ASA are rare but pose a significant risk of rupture and mortality.
  • Surgical repair is generally recommended for ASA aneurysms.

Observation:

  • A review of 4 cases of ASA aneurysms treated over 23 years.
  • All patients were male, aged 51-73 years.
  • Three patients presented with a right-sided aortic arch.

Findings:

  • Only one patient required surgical intervention (total arch replacement).
  • Three patients were managed conservatively with follow-up periods of 1, 7, and 23 years.
  • Conservative management can be a viable option for specific ASA aneurysm cases.

Implications:

  • This case series highlights the variability in ASA aneurysm presentation and management.
  • It suggests that conservative follow-up may be appropriate for certain patients, challenging the universal surgical indication.
  • Further research is needed to refine indications for surgery versus conservative management in ASA aneurysms.
