Abstract OBJECTIVES We investigated the outcomes of total arch replacement with frozen elephant trunk (FET) for Stanford type A acute aortic dissection and the patterns of postoperative aortic remodelling from computed tomographic (CT) findings. METHODS From April 2015 to November 2018, we performed total arch replacement with FET for Stanford type A aortic dissection in 30 patients. Postoperative contrast-enhanced CT showed the position of the FET distal end, the number and the site of communications between the lumina and the presence or absence of aortic remodelling. RESULTS Primary entry tear was found in the ascending aorta (n = 6), proximal arch (n = 6), aortic arch (n = 11) and distal arch (n = 7). The mean diameter and length of FET were 26 ± 2 and 84 ± 18 mm, respectively. Postoperative contrast-enhanced CT was performed in 26 patients. When the number of communications between the lumina was 0, complete aortic remodelling was achieved in all cases (n = 12). In the case of the most proximal tear in the descending aorta (n = 9), aortic remodelling was not recognized in 3 cases, and additional TEVAR was performed because of diameter enlargement. In the remaining 6 patients, neither aortic remodelling nor aortic diameter enlargement was recognized. When the most proximal tear was below the diaphragm (n = 5), aortic remodelling occurred up to the most proximal tear, but not in the periphery. CONCLUSIONS We investigated the patterns of aortic remodelling after total arch replacement with FET for Stanford type A aortic dissection from postoperative CT findings. Regardless of the position of the most proximal tear in the descending aorta, aortic remodelling did not occur as long as the most proximal tear was located in the descending aorta. When the most proximal tear occurred in the descending aorta, TEVAR as a pre-emptive treatment can be effective in preventing postoperative aortic adverse events.

Background Total arch replacement with modified elephant trunk technique plays an important role in treating acute type A aortic dissection in China. We aim to summarize the therapeutic effects of this procedure in our center over a 17-year period. Methods Consecutive patients treated at our hospital due to type A aortic dissection from January 2004 to January 2021 were studied. Relevant data of these patients undergoing total arch replacement with modified elephant trunk technique were collected and analyzed. Results A total of 589 patients were included with a mean age of 53.1 ± 12.2 years. The mean of cardiopulmonary bypass, cross-clamping, and selected cerebral perfusion time were 199.6 ± 41.9, 119.0 ± 27.2, and 25.1 ± 5.0 min, respectively. In-hospital death occurred in 46 patients. Multivariate analysis identified four significant risk factors for in-hospital mortality: preexisting renal hypoperfusion (OR 5.43; 95% CI 1.31 – 22.44; P = 0.020), cerebral malperfusion (OR 11.87; 95% CI 4.13 – 34.12; P < 0.001), visceral malperfusion (OR 4.27; 95% CI 1.01 – 18.14; P = 0.049), and cross-clamp time ≥ 130 min (OR 3.26; 95% CI 1.72 – 6.19; P < 0.001). The 5, 10, and 15 years survival rates were 86.4%, 82.6%, and 70.2%, respectively. Conclusions Total arch replacement with modified elephant trunk technique is an effective treatment for acute type A aortic dissection with satisfactory perioperative results. Patients with preexisting renal hypoperfusion, cerebral malperfusion, visceral malperfusion, and long cross-clamp time are at a higher risk of in-hospital death.

Abstract Although isolated left vertebral artery is a supra-aortic trunk variant, it is not so rare. It may pose additional difficulties during total arch replacement surgeries. The aim of this study was to present our experience with prior reconstruction of isolated left vertebral artery by isolated left vertebral artery–left common carotid artery during total arch replacement combined with stented elephant trunk implantation.

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 &gt; 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.

AbstractAcute aortic dissection is a rare but devastating complication during cardiac catheterization. We present the case of an elderly female who incurred a Stanford Type A/DeBakey Type I acute aortic dissection extending into the arch vessels and descending aorta likely occurring during right coronary artery engagement for angioplasty. The patient was treated successfully by immediately sealing the entrance of the dissection via the placement of a stent and anti-impulse therapy. Follow-up computed tomography scan showed complete resolution of the dissection within one month.
