Suprarenal aneurysms

Novel approaches to the treatment of juxtarenal and suprarenal aneurysms... 

The endovascular procedure is most frequently used to treat infrarenal AAAs that are a leading cause of death in the older population, As our population ages, we will encounter AAAs more frequently than ever before. An aneurysm is defined by a size greater than 5 cm or 2.5 times the normal diameter of the native artery. Most aneurysms begin below the renal arteries and end close to the iliac bifurcation. More complicated AAAs exist involving the suprarenal aorta and visceral vessels and extending into the iliac arteries. The prevalence of AAAs is 3% to 10% for patients older than 50 years (I). They occur more frequently in men and reach a peak incidence close to the age of 80 years. AAA rupture is associated with an 80% to 90% mortality rate and therefore the focus of AAA treatment is on intervening before the aneurysm ruptures elective repair has mortality rate of less than 5%.
