Abdominal aortic aneurysm rupture has a high mortality rate. Conservative management is recommended for aneurysms smaller than 5 cm, while larger aneurysms require surgical repair to prevent rupture.

Area of Science:

  • Vascular Surgery
  • Medical Imaging
  • Aneurysm Management

Background:

  • Abdominal aortic aneurysm (AAA) rupture has a high mortality rate (80%-90%).
  • Preventing AAA rupture is the primary treatment goal.
  • Conservative surveillance is recommended for smaller AAAs.

Purpose of the Study:

  • To outline current management strategies for abdominal aortic aneurysms.
  • To compare open surgical repair with endovascular graft repair for AAAs.

Main Methods:

  • Conservative management involves regular surveillance using computed tomography or sonography (3-12 month intervals).
  • Surgical intervention is recommended for aneurysms >5 cm.
  • Treatment options include open surgical repair and endovascular graft repair.

Main Results:

  • AAA growth averages 2-4 mm/year with a 1-5% annual rupture risk.
  • Open surgical repair has a 2-8% mortality rate and 7-10 day hospital stay.
  • Endovascular grafts offer shorter hospital stays (1-3 days), but long-term durability is unproven.

Conclusions:

  • Early detection and surveillance are crucial for managing small abdominal aortic aneurysms.
  • Surgical repair, either open or endovascular, is necessary for larger aneurysms to prevent rupture.
  • Endovascular repair offers short-term benefits, but long-term outcomes require further investigation.
