[|AI|]  Hello, That is correct, generally speaking, most vascular surgeons do not consider repairing aortic aneurysms until they reach a size of about 5 cm. This is because the risk of complicated rupture is great, and we know that major complications of rupture do not elevate substantially until an aneurysm gets to about 5 cm. Then, the risks versus benefits of the procedure and possible complications balance in favor of intervening if that makes sense. Hope I have answered your query. Let me know if I can assist you further.
