Abstract OBJECTIVES The aim of this study was to evaluate the outcomes of the frozen elephant trunk (FET) technique, using the J Graft FROZENIX for Stanford type A acute aortic dissection, in comparison with the unfrozen elephant trunk technique. METHODS Between January 2010 and August 2018, we performed total arch replacement for Stanford type A acute aortic dissection in our hospital. Thirty patients were treated by the elephant trunk procedure (ET group), and 20 patients were treated by the FET procedure (FET group). To evaluate aortic remodelling, we measured the area of the aorta, the true lumen and the false lumen at 12 months of follow-up. RESULTS Preoperative characteristics and operation time were not significantly different between the 2 groups. The quantity of blood transfused was much greater in the ET group than in the FET group. Resection or closure of the most proximal entry tear was obtained in 73.3% (22 out of 30 patients) in the ET group and 100% (20 out of 20 patients) in the FET group (P = 0.015). There was no case that had recurrent nerve palsy or paraplegia in the FET group. Stent graft-induced new entry occurred in 3 cases (15.8%) in the FET group. There were no significant differences between the 2 groups in aortic area, true lumen area or false lumen area. CONCLUSIONS Total arch replacement with the FET technique in Stanford type A acute aortic dissection carries a risk of distinct complications; however, with thorough advance planning, it should be possible to safely institute this treatment. Further randomization, with a comparison of each technique, is required to provide clear conclusions whether the FET is useful for acute Stanford type A aortic dissection.

Abstract OBJECTIVES Aortic dissection (AoD) in the presence of an aberrant right subclavian artery (ARSA) is very rare. Clinical experience is limited, and there is no consensus regarding the optimal management strategy. We seek to evaluate the safety and efficacy of the total arch replacement (TAR) and frozen elephant trunk (FET) technique as an approach to AoD in patients with ARSA by retrospectively analysing our single-centre experience. METHODS From 2009 to 2017, we performed TAR + FET for 22 patients with ARSA sustaining AoD (13 acute, 59.1%). The mean age was 46.0 years [standard deviation (SD) 8.3], and 19 patients were male (86.4%). ARSA orifice was dilated in 15 (68.2%) patients, and a Kommerall diverticulum was diagnosed in 13 (59.1%) patients with a mean diameter of 21.8 mm (SD 7.7; range 15–40). Surgery was performed via femoral and right/left carotid cannulation under hypothermic circulatory arrest at 25°C. The ARSA was reconstructed using a separate branched graft. RESULTS ARSA was closed proximally by ligation in 16 (72.7%) patients, direct suture in 4 (18.2%) patients and both in 2 (9.1%) patients. Operative mortality was 13.6% (3/22). Type Ib endoleak occurred in 1 (4.5%) patient at 8 days. Follow-up was complete in 100% at mean 4.2 years (SD 2.0), during which 3 late deaths and 1 reintervention for type II endoleak occurred. Survival was 81.8% and 76.4% at 3 and 5 years, respectively. Freedom from reoperation was 89.2% up to 8 years. In competing risks analysis, the incidence was 22.1% for death, 10.8% for reoperation and 67.1% for event-free survival at 5 years. The false lumen, ARSA orifice and Kommerall diverticulum were obliterated in 100%. Grafts were patent in 100%. No patients experienced cerebral ischaemia and upper extremity claudication. Hypothermic circulatory arrest time (min) was sole predictor for death and aortic reintervention (hazard ratio 1.168, 95% confidence interval 1.011–1.348; P = 0.034). CONCLUSIONS The TAR and FET technique is a safe and efficacious approach to AoD in patients with ARSA. Modifications of routine TAR + FET techniques are essential to successful repair, including femoral and right/left carotid artery cannulation, ligation of ARSA on the right side of the trachea and ARSA reconstruction with a separate graft.

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.
