Open surgery for descending thoracic aorta in an endovascular era
2018
Abstract Background Thoracic endovascular aortic repair has become the preferred treatment for a variety of descending thoracic aortic pathologies. However, there are unresolved issues such as morphologic appearance of chronic dissection, persistent false lumen perfusion, and adequacy of landing zone. Enthusiasm for improving the technique of open aortic repair and perioperative management is fading. In this study, we would like to demonstrate how we improve our surgical outcomes by establishing a dedicated aortic multidisciplinary team at the Kawasaki Aortic Center. Method We performed a single-center retrospective study from January 2015 to December 2016. All patients with open descending thoracic aortic replacement were recruited. Preoperative patient demographic data, bypass strategies, operative details, and postoperative outcomes were reviewed. Result From January 2015 to December 2016, we treated 168 cases of descending thoracic aortic repair using a left thoracotomy. Median age was 69.0 ± 21.8 years old, and 63.1% were aortic dissection (acute, 4.8%; chronic, 58.3%); 81.3% patients underwent elective operations. Left heart bypass, deep hypothermic circulatory arrest, and partial cardiopulmonary bypass were performed in 88.6%, 9.0%, and 2.4% of patients, respectively. Mean operative time was 312 ± 94 minutes. In-hospital mortality in total was 0.6%. The rate of transient spinal cord injury was 4.7%. Conclusions Under a dedicated aortic multidisciplinary team, we demonstrated that open descending thoracic aorta replacement can be performed with excellent early outcomes with low reintervention rates, regardless of the nature of the aortic pathologies.
