The Texas Medical Center has been home to pioneering aortic surgeons Michael E. DeBakey, Denton A. Cooley, and E. Stanley Crawford, on whose legacies modern thoracoabdominal aortic surgery has been built. During the past 3 decades, our single-center practice (led by J.S.C.) has performed more than 3600 open thoracoabdominal aortic aneurysm repairs (TAAARs), including the largest published series to date (N ¼ 3309). 1 Continuing to refine the perioperative management of TAAAR patients is critical. In this 2-part series, we discuss the current practice at Baylor College of Medicine/CHI Baylor St Luke's Medical Center in Houston, Texas. Part 1 of this report focuses on unique preoperative considerations to reduce the risk of adverse operative outcomes. Part 2 focuses on postoperative management to reduce the risk of complications and to manage those that arise. Although other experienced centers may have different approaches to common conditions and produce good surgical outcomes, we provide this guide as a foundation for surgeons, intensivists, trainees, advanced practice providers, nurses, and others involved in the multidisciplinary management of these complex surgical patients.
PREOPERATIVE CONSIDERATIONSWe have described our approach to preoperative planning in detail. 2 Briefly, we assess age and physiologic reserve, stratify risk, stop antiplatelet and anticoagulant medications, advise tobacco cessation, and optimize major neurologic, cardiovascular, respiratory, and renal comorbidities. 3 The major surgical risks include mortality, paraplegia, renal failure, stroke, respiratory failure, and myocardial infarction. Each of these risks is discussed with the patient and family. Surgical timing is influenced by aneurysm size and growth rate; presence of leak, rupture, or acute dissection; and symptomatology (Table 1). 2
