Abstract OBJECTIVES Resection of a primary entry tear is essential for the treatment of Stanford type A acute aortic dissection (AAAD). In DeBakey type III retrograde AAAD (DBIII-RAAAD), resection of the primary entry tear in the descending aorta is sometimes difficult. The frozen elephant trunk technique and thoracic endovascular aortic repair (TEVAR) enable the closure of the primary entry in the descending aorta. The aim of this study was to investigate the efficacy of resection or closure of primary entry, i.e. entry exclusion, in patients with DeBakey type III retrograde-AAAD. METHODS The medical records of 654 patients with AAAD who underwent emergency surgery between January 2000 and March 2019 were retrospectively reviewed, and 80 eligible patients with DeBakey type III retrograde-AAAD were divided into the excluded (n = 50; age, 62 ± 12 years) and residual (n = 30; age, 66 ± 14 years) groups according to postoperative computed tomography angiographic data of the false lumen around the primary entry. The excluded group was defined as having a postoperative false lumen at the level of the elephant trunk or thrombosis of the endograft including primary entry. Patients with early false lumen enhancement around the elephant trunk or an unresected primary entry tear after isolated hemiarch replacement were included in the residual group. The early and long-term surgical outcomes were compared between the groups. RESULTS The in-hospital mortality rate was 8% (6/80), with no significant difference observed between the excluded and the residual groups (10% and 7%, respectively; P > 0.99). Ninety-five percentage of the patients (20/21) achieved entry exclusion with stent grafts including the frozen elephant trunk procedure and TEVAR. Spinal cord ischaemia was not observed in either group. The cumulative overall survival at 5 years was comparable between the 2 groups (76% and 81% in the excluded and residual groups, respectively; P = 0.93). The 5-year freedom from distal aortic reoperation rate was significantly higher in the excluded group (97%) than in the residual group (97% vs 66%; P = 0.008). CONCLUSIONS Not only resection but also closure using the entry exclusion approach for DeBakey type III retrograde-AAAD utilizing new technologies including the frozen elephant trunk technique and TEVAR might mitigate dissection-related reoperations.
