Title: CSP #498 - Open Versus Endovascular Repair (OVER) Trial for Abdominal Aortic Aneurysms
Brief Summary: A multi-center, randomized clinical trial that will compare endovascular repair with standard open surgery in the repair of abdominal aortic aneurysms (AAA). Long and short-term results as well as the cost and quality of life associated with these two strategies for AAA repair will be compared.


Options:
A: Inclusion Criteria:

* AAA with a maximum external diameter in any plane greater than or equal to 5 cm.
* An iliac aneurysm (associated with an AAA) with a maximum external diameter in any plane greater than or equal to 3 cm.
* AAA greater than or equal to 4.5 cm and the AAA has increased by greater than or equal to 0.7 cm in diameter in 6 months.
* An AAA greater than or equal to 4.5 cm and the AAA has increased by greater than or equal to 1 cm in diameter in 12 months.
* An AAA greater than or equal to 4.5 cm and the AAA is saccular (i.e., a portion of the circumference of the aorta at the level of the aneurysm is considered normal based on CT scan or MRI).
* An AAA greater than or equal to 4.5 cm and the AAA is associated with distal embolism.

  * as measured from two imaging studies (ultrasound CT scan or MRI) within the appropriate interval, the later one within 6 months of randomization.

Exclusion Criteria:

* Patient has had a previous AAA repair procedure
* Evidence of AAA rupture by imaging test
* AAA is not elective (i.e., urgent or emergent operation, usually due to suspected rupture)
* Likelihood of poor compliance to the protocol
* Patient refused randomization
* Physician refused randomization
B: Inclusion Criteria:

* Asymptomatic, infrarenal AAA that requires surgery
* Adequate infrarenal neck
* Other aortic-iliac anatomical configuration suitable for EVAR according to the criteria of the device to be used
* Patient having a life expectation of at least 2 years and cleared for transabdominal intervention
* Signed informed consent

Exclusion Criteria:

* ruptured AAA or symptomatic AAA, which requires emergency surgery
* maximum aneurysm diameter\< 5.0 cm
* suprarenal AAA
* Inflammatory AAA (more than minimal wall thickening)
* infrarenal neck unsuitable for endovascular fixation or aortic-iliac anatomic configuration otherwise unsuitable for EVAR according to criteria of the device to be used
* bilateral retroperitoneal incision required for EVAR
* sacrifice of both hypogastric arteries required
* anatomical variations, i.e. horseshoe-kidney, arteries requiring reimplantation
* patient unsuitable for laparotomy
* administration of contrast agent not possible: proved, severe systemic reaction to contrast agent
* active infection present
* transplantation-patients
* limited life expectation due to other illness (\< 2 year)
* non-iatrogenic bleeding diathesis
* connective tissue disease
C: Inclusion Criteria:

* Patients of 50-80 years of age
* Non symptomatic infrarenal AAA of 4.1 to 5.4 cm in diameter measured by CT performed within 3 months before randomization
* Adequate infrarenal aortic neck (length \> 15 mm diameter \< 30 mm) and other anatomical configurations suitable for EVAR
* Patients have a life expectancy of at least 5 years
* Signed informed consent

Exclusion Criteria:

* Ruptured or symptomatic AAA
* AAA maximum diameter \>= 5.5 cm
* Suprarenal or thoracic aorta aneurysm of more than 4.0 cm
* Patient unsuitable for administration of contrast agent
* Severe heart, lung, liver or renal disease (serum creatinine \>= 3mg/dl)
* Need for adjunctive major surgical or vascular procedures within 1 month
* High likelihood of non compliance with follow-up requirements
D: Inclusion Criteria:

* Patients aged 50 years old or more (more than 80 possible depending on physiological age)
* Level 0, 1, or 2 of operative risk
* Abdominal aortic aneurysm with a diameter \> or equal to 50 mm or \> or equal to 40 mm if rapid growing (10 mm or more in a year), or painful, or saccular aneurysms, or aneurisms of common iliac arteries with a diameter equal or superior to 30 mm; or women with a diameter equal to 45 mm;
* Aortic neck superior or equal to 1.5 cm
* No stenosis superior or equal to 75% of the superior mesenteric artery
* Proximal neck angulation inferior to 80°
* Diameter of the iliac arteries compatible with introducer sheath
* Inform consent signed

Exclusion Criteria:

* Aneurysm involving the renal arteries or with the length of the neck less than 1.5 cm
* Thrombus or major calcification in the neck
* Diameter of the iliac arteries not compatible with introducer sheath
* Level 3 of operative risk
* History of major iodine allergy (Quincke oedema, anaphylactic shock)
* Other comorbidity with life expectancy less than 6 months
* Follow up impossible during the trial
* Participation in another trial
* Inform consent not signed
