Saccular aortic aneurysms are rare but often symptomatic, requiring surgical repair. Management varies by location, with patch grafts for thoracic/suprarenal and tube grafts for infrarenal types.

Area of Science:

  • Vascular Surgery
  • Aortic Pathology

Background:

  • Saccular aortic aneurysms are believed to have a worse prognosis than fusiform aneurysms.
  • Surgical intervention is often recommended due to concerns about rupture risk, even in asymptomatic cases.

Purpose of the Study:

  • To review the clinical presentation and surgical management of saccular aortic aneurysms.
  • To analyze patient data based on the anatomic location of the aneurysm.

Main Methods:

  • Retrospective review of 10 patients who underwent surgical repair of saccular aortic aneurysms between 1985 and 1998.
  • Patients were categorized into four groups based on aneurysm location: distal arch, descending thoracic, visceral, and infrarenal aorta.

Main Results:

  • Saccular aortic aneurysms are uncommon, predominantly found in the thoracic and suprarenal aorta.

Related Experiment Videos

  • Most surgically treated cases presented with symptoms.
  • Thoracic and suprarenal aneurysms were often repaired with patch grafts, while infrarenal aneurysms typically required tube graft replacement due to atherosclerosis.

    • Conclusions:

    • Surgical repair techniques for saccular aortic aneurysms differ based on location.
    • Distal arch repairs necessitate hypothermic circulatory arrest.
    • Endovascular techniques may offer future treatment options.
