That is the theory, but large centers see many of the complications (whatever that presentage 10-90%, it makes a hugh difference) and us little guys almost never see these problems. Is this like the simple AVR data verses root cause I can? Is there any good data or just Kodak moments? If the latter, we shouldn't make light of "saving lives", nor assume only the referal centers are making a positive difference in peoples live. 

I believe our difference on this point, Ani, since we have it in many contexts is largely epistemological and not data or factual. I will try to address this philosophical issues in a few postings as i think we (collectively) spend a huge amount of time stumbling over this issue, when we might could avoid error if we at least predict the dead ends that we think ourselves into. Again this is not an argument that i am "correct" about any particular subject which in this posting happens to be aortic surgery.

But Tea in this case the do nothing (medical therapy we call it) is particularly lethal. 

Without access to data, it is difficult to see how this 62 year olds life expectancy can be better without surgery. Provided he has no comorbidity (stroke was presumably related to dissection or surgery and is distant) most aortic centers would undertake this procedure with a mortality risk of no more than 10% (but adding another 10 to 15% though if he needs a two stage procedure i.e elephant trunk then TAA). I do not know about endovascular 'solutions'.

I do not see what a 3 to 6 month follow-up would achieve here as the patient already has 'indications' for surgery and his condition cannot by definition improve on medical therapy. Unless of course we deem that the condition is inoperable or that the risks outweigh the benefits - but even then what would the follow-up achieve (unless you expect to modify either the risk or benefit over the 3 to 6 month period)?

This patient was short-changed at his first operation. He was fortunate to have his life saved for 6 years but was not given a lasting solution - while that is preferable to death, more preferable would have been a more lasting solution at the first surgery. I was at a meeting recently and the theme seems to be that because we are treating an often lethal condition, any operation that attempts to save life is acceptable at whatever outcome. This is in preference to driving excellence in this procedure and improving outcomes (for example demanding we replace the root and arch when indicated). So Type A dissection remains one of those forgotten diseases - many have their lives 'saved' but will in the medium-term have a relapse of their vascular disease. Overall I suspect the life expectancy of patients with Type A will be much better if they all had a complete and durable operation (and not just a focus on immediate life saving), even if it means
 transferring patients elsewhere (and we should not say that is unsafe - I suspect the majority of patients with type A are not operated at the first hospital they present) - than the present approach where the first surgeon who gets hold of it does the best operation they know how to do.

PS - rabies therapy is painful too. Certainly given a choice at age 11 I would still chose an arch operation at 62 years in preference to 3 weeks of intraperitoneal injections at age 11....economists call that 'time preference'.

I have operated myself, probably often enough, where there are criteria but after a poor outcome I wonder whether there were strong enough. And unlike Ani's refusal of the rabies shot our therapy is not only painful, but lethal.> > > tea> > > ----- Original Message ---->

I would really need to see the films, but from what you describe what this guy needs is a reop with removal of his previous graft, AVR or possible root or maybe a valve sparing procedure depending on the root and valve anatomy, and either an elephant trunk or a arch debranching with bypass grafts to the innom and carotid, creating a landing zone for a future stent graft for the descending. If he has no available landing zone near his celiac then an thoracoabdominal resection/repair would most likely be in his future. At 62, as long as he doesn't have any horrible comorbidities, his in hospital survival will be in the 90% range.> > Good luck.> > > > Tom Martin> > U of Florida> > Gainesville> > >
