Aneurysm formation is associated with a chronic inflammatory response, depletion of smooth muscle cell population and excessive matrix metalloproteinases (MMPs) production. 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) are lipid lowering agents with pleiotropic effects including anti-inflammatory activity. Elective open AAA repair patients will be randomised to receive either statin (Atorvastatin 80 mg) or placebo (dummy tablet) for 4 weeks pre-operatively. Tissue samples will be obtained from patient's aneurysm to assess MMP's and their inhibitors TIMP's. It is hypothesized that patients receiving statin will have reduced MMP's.
All patients listed for elective open AAA repair will be screened for suitability to participate within the study. In this double blind randomized control trial patients will be recruited through vascular surgical outpatient clinics. After inclusion, informed consent and evaluation of base line characteristics patients will be given a prescription for study medication. This prescription was exchanged by the patient for medication at the hospital pharmacy. Randomization will be carried out by pharmacy with computer generated sequence with a sub group size of 4. This will ascertain the order of prescribed drug/ placebo. Pharmacy then dispensed the drug/ placebo in this order. Drug used will be Atorvastatin 80 mg, white, elliptical, film coated tablets debossed '80' on one side and 'PD 158' on the other side. The placebo is similar in shape and colour. Drug/ placebo will be given for 4 weeks pre-operatively. Full thickness infrarenal aortic samples will obtained at time of operation and the exact sample site will be recorded. Samples will be washed with 0.9% saline to remove blood and clots, snap-frozen and stored at -80C for subsequent MMP 2, 8 and 9 and TIMP 1 and 2 analyses.

An abnormal balloon- or sac-like dilatation in the wall of the ABDOMINAL AORTA which gives rise to the visceral, the parietal, and the terminal (iliac) branches below the aortic hiatus at the diaphragm.
The tearing or bursting of the wall along any portion of the AORTA, such as thoracic or abdominal. It may result from the rupture of an aneurysm or it may be due to TRAUMA.
Postoperative hemorrhage from an endovascular AORTIC ANEURYSM repaired with endoluminal placement of stent grafts (BLOOD VESSEL PROSTHESIS IMPLANTATION). It is associated with pressurization, expansion, and eventual rupture of the aneurysm.
Cardiovascular manifestations of SYPHILIS, an infection of TREPONEMA PALLIDUM. In the late stage of syphilis, sometimes 20-30 years after the initial infection, damages are often seen in the blood vessels including the AORTA and the AORTIC VALVE. Clinical signs include syphilitic aortitis, aortic insufficiency, or aortic ANEURYSM.
Solitary lesions of bone that typically cause a bulging of the overlying cortex bearing some resemblance to the saccular protrusion of the aortic wall in aortic aneurysm, hence the name. (Dorland, 27th ed)
