The treatment of thoraco-abdominal aortic aneurysms (TAAAs) is extremely laborious, due to the surgical complexity of this condition. In particular, postoperative spinal paraplegia poses a severe complication that significantly lowers patient's quality of life. In 1997, we devised a hybrid procedure consisting of extended endovascular aortic repair (EVAR) and visceral ...
Bosman Willem-Maarten P F - - 2010
One of the major concerns in the long-term success of endovascular aneurysm repair (EVAR) is stent graft migration, which can cause type I endoleak and even aneurysm rupture. Fixation depends on the mechanical forces between the graft and both the aortic neck and the blood flow. Therefore, there are anatomical ...
Rancic Zoran - - 2010
Endovascular aneurysm repair (EVAR) of ruptured thoracoabdominal aortic aneurysms may be compromised or even impossible due to short proximal and/or distal necks or landing zones, respectively. Supra-aortic branches may limit the proximal anchorage and visceral or renal arteries the distal anchorage of endografts. While solutions have been proposed to overcome ...
