Children with hypercholesterolemia have an early increase of oxidative stress that may be responsible for up-regulation of CD40L and potentially predispose to premature atherosclerosis.

The proximal aortic neck is one of the limiting factors for endovascular aneurysm repair (EVAR) and represents a crucial factor for success or failure of the procedure. In contrast to open surgery, where a clamp can be placed suprarenally but the repair performed infrarenally, EVAR requires a good infrarenal neck for durable fixation and seal. In a high-risk surgical 79-year-old patient with juxtarenal aortic aneurysm with unsuitable infrarenal neck, a hybrid procedure was chosen: juxtarenal aortic banding and EVAR. The banding allowed a successful EVAR by reshaping the juxtarenal aneurysmal aortic segment, hence converting a previously untreatable anatomy into a treatable one.
