Postimplantation syndrome. Postimplantation syndrome is an inflammatory response fol- lowing aortic repair that results in fever and malaise and often includes leukocytosis and eleva- tion of inflammatory mediators such as C-reactive protein.
The clinical significance of this syndrome is not currently known and is often indistinguishable from an infection. It was initially thought to be a self-limiting reac- tion that resolves within 2 weeks of implantation; however, these patients have increased rates of renal insufficiency, prolonged lengths of stay, and higher mor- tality.8,9,26 Further studies are needed to establish diagnostic cri- teria and treatment guidelines.
Ischemic bowel. Mesenteric complications may result from aortic dissection or from emboli released during manipulation of the aorta during repair.
