Management of type A dissection with malperfusion
Malperfusion is a common lethal complication of acute aortic dissection following rupture, for which the optimal management strategy has yet to be clearly established. The objective of this study was to reassess the management of acute type A aortic dissection (Type A-AAD) with malperfusion. We retrospectively analyzed the outcomes of all patients with Type A-AAD with malperfusion at the University of Michigan and compared the results from patients that directly underwent open surgical repair versus those who had percutaneous reperfusion prior to open surgical repair. Based on the results, we developed a patient care protocol for the treatment of all patients with acute type A dissection. We later re-analyzed the long-term outcomes for patients using the protocol. The present study demonstrated that, although the outcomes for patients with acute type A aortic dissection with malperfusion syndrome treated with initial percutaneous reperfusion and delayed open surgical intervention are not as good as the results for patients with uncomplicated Type A-AAD that undergo immediate surgical repair, their outcomes continue the long-term outcomes of the former group are superior. To outdo patients with acute type A aortic dissection with malperfusion syndrome treated with immediate open surgical intervention. In conclusion, at the University of Michigan we continue to use our patient care protocol to treat patients with Type A-AAD.
