Father 60 had high BP and bad cholesterol and made echo of heart, CT of brain and ultra of carotid. Has no symptoms but should he check for aneurysms?

Once. The United States Preventive Services Task Force just issued guidelines for this last month: (Annals of Internal Medicne, 2014, 161:281-290.) They recommend a 1 time screening for men aged 65-75 who have ever smoked. For men who have never smoked, it's a toss up. Your father's a bit young, but if he would feel better about it, why not?
