Open AAA Repair Endovascular Repair
Procedure Diseased aorta is replaced by a tube or bifurcated graft through an abdominal or retroperitoneal incision Graft components are delivered through the femoral arteries and lines the diseased aorta to exclude it from the circulation
  • More readily available in facilities than endovascular repair
  • Reduced peri-operative morbidity and mortality compared to open approach
  • Less invasive
  • Higher peri-operative morbidity and mortality 
  • More invasive
  • Requires specialised facilities
  • Not all patients will be anatomically suitable for endovascular repair
