Abstract

Background To analyze survival, neurologic injury, and kidney function after acute type A aortic dissection. Methods A total of 445 patients undergoing surgery for acute type A aortic dissection were analyzed. Evaluation according to risk factors for mortality, neurologic injury, and kidney function was performed. Results Overall 1-, 5-, and 10-year survival rates were 82.8 ± 1.8%, 73.6 ± 2.4%, and 59.3 ± 3.9, respectively. Independent preoperative risk factors for mortality were preexisting renal impairment (p = 0.001), reduced left ventricular ejection fraction (p < 0.001), and age (p < 0.001). Perioperative risk factors were prolonged cross-clamp (p < 0.001) and cerebral perfusion time (p = 0.001). Risk factors for renal failure were preexisting renal impairment (p < 0.001), prolonged cross-clamp time (p < 0.001), cerebral perfusion time (p < 0.001), and age (p = 0.022). Risk factors for neurologic injury were cross-clamp time (p = 0.038), cerebral perfusion time (p = 0.007), and age (p = 0.045). Conclusion In addition to classic risk factors, survival after type A aortic dissection is affected by preexisting renal impairment. Preexisting renal impairment is predictive of postoperative renal failure. Therefore treatment and prevention strategies for renal failure during the acute and long-term course after acute type A aortic dissection are warranted.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
