Title: Positive Impact of Endovascular Options for Treating Aneurysms Early (PIVOTAL)
Brief Summary: The purpose of this study is to compare endovascular repair using any FDA approved Medtronic AAA Stent Graft System versus surveillance in subjects with smaller abdominal aortic aneurysms (AAA)(4-5CM), with respect to AAA rupture and AAA related deaths.


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:

* 40 to 90 years of age
* Meet all indications for use as stated in the Medtronic Vascular AAA Endograft Instructions for Use
* Maximum aneurysm diameter of 4-5cm
* If female patient with child bearing potential, must have a documented negative pregnancy test within seven(7)days prior to inclusion
* Patient is willing and able to comply with the specified follow-up evaluation
* Life expectancy at least 3 years

Exclusion Criteria:

* Meet any of the Contraindications stated in the Medtronic Vascular AAA Endograft instructions for Use
* Known co-existing condition with a life expectancy of less than 3 years
* Major surgical or interventional procedure (vascular and/or non-vascular)within 30 days prior to study enrollment
* Subjects enrolled in another clinical trial or anticipated to be included into a trial, which may interfere with this study, or subjects already enrolled in this trial before.
* Planned conduit procedure for introduction of endograft
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
