Is a septorhinoplasty possible on a patient who has damaged veins from past heroin use? 10 years clean

Ex heroin user clean over 10 yrs. I've made something of myself, I am a new person. I'd like to have rhino/septoplasty done (broke my nose years ago) but worried that my veins are no good for an IV. Have dead damaged veins everywhere, hands, arms, fingers, neck, forehead, feet, thighs, armpits etc. Honestly don't know how I have blood flowing in me. So ashamed of my past that I’m too embarrassed to ask my primary care doctors' opinion.
