Abdominal aortic aneurysm

Abdominal aortic aneurysm

AAA is the most serious and widespread vascular disease overall. When the wall of a blood vessel weakens, a balloon-like dilation called an aneurysm sometimes develops and can break if not treated in time. This lead to severe complication or potential death. This happens most often in the abdominal aorta, an essential blood vessel that supplies blood to our legs.

There are two approaches for treatment:

  • Open repair with higher rates of morbidity and mortality,
  • Endo Vascular Aneurysm Repair (EVAR) is minimally invasive stent-graft with lower mortality rate.

Type II endoleaks is the most common complication after an EVAR leading to severe aggravation if not treated

  • 40% aneurysms still growing after EVAR
  • 80% caused by type II endoleaks

Existing treatments leave the AAA therapeutic need largely unmet.
