Aortic Aneurysm The natural history of aneurysms is to enlarge and rupture The primary objective of aneurysm repair is to prevent rupture, while minimizing treatment related risks and preserving functional outcome

MEN Choose Endograft Repair Because… • An Endograft Repair will almost always preserve “A Man’s function” Impotence 10-40% with open AAA Surgery
Follow-up goals To assess: Endograft Aneurysmatic sack Anchoring zone
AAA Follow up Timing Echo color Doppler 1 6 12 18 30 42 1 12 24 36 48 TC / MR scan
TAA Follow up Timing 1 6 12 24 36 48 TC / MR scan

Conclusion Higher risk of Aneurysm related death with open surgery Significant increase in late Morbility with open surgery Early functional outcomes better with endovascular repair
KEY to success: • Appropriate patient selection • Team experience • Appropriate timely follow up Conclusion • EVAR represents a viable alternative with a low risk if compared to open surgery
Open questions New device technology Long term Follow up New follow up technology
