Abstract:
Objective: The aim of this study was to evaluate the therapeutic efficacy of Liu's aortic root repair strategy for patients with a complicated aortic root in acute type A aortic dissection (ATAAD) .
Methods: From October 2011 to December 2019, 473 consecutive patients underwent surgical aortic repair of ATAAD at Second Hospital of Jilin University. We divided these patients into two groups: 162 patients with complicated aortic root (34.2%) and 311 patients without complicated aortic root (65.8%). Patients with complicated aortic root were divided into 4 types: 1, aortic sinus diameter < 4.5 cm, but sinotubular junction (STJ) diameter ≥ 4.5 cm, 24 patients; 2, coronary involvement, including Neri. type A, B and C8, 86 patients; 3, aortic sinus diameter ≥ 4.5 cm with significant dilatation in the non-coronary sinus only, 19 patients; 4, aortic sinus diameter ≥ 4.5 cm with Marfan syndrome or other hereditary thoracic aortic disorder, or aortic sinus diameter ≥ 5.0 cm and excessive dilatation of the aortic root involving two or three sinuses of Valsalva, 33 patients; respectively (Figure 1). We focused on assessing the therapeutic efficacy of Liu's aortic root repair strategy in the 162 patients.
Results: 33 patients received Modified Bentll procedure for aortic root aneurysm, and the remaining 129 patients were performed Liu's aortic root repair. In addition, 24 patients received coronary artery bypass surgery for Neri. type C coronary involvement. Overall in-hospital mortality was 5.6%. The 1-year, 3-year, and 5-year survival estimates were 90.7%, 84.5%, and 80.6%, respectively. At a median follow-up of 48.2 (interquartile range, 23.1-67.7) months, all patients were free from reoperation for aortic root disease, such as: recurrent aortic root dissections, residual false lumens in the aortic root, aortic root pseudoaneurysms, and severe aortic regurgitation.
Conclusions: In type A aortic dissection with complicated aortic root except aortic root aneurysm, Liu's aortic root repair is a safe and effective surgical strategy that achieves favorable outcomes.
