In many countries the gold standard for treating abdominal aortic aneurysms is still open surgery with a long incision. In patients with suitable anatomy alternatively an endovascular approach can be chosen. Since open surgery is more durable in many countries a laparoscopic procedure using " key hole surgery " has gained wider acceptance. The current study wants to prove that laparoscopic aortic aneurysm procedures are less invasive than open surgery with reduced recovery times.
