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.

Long Term Survival

Abstract OBJECTIVES We evaluated the operative and long-term outcomes of the frozen elephant trunk (FET) technique for acute type A aortic dissection. METHODS This study evaluated 426 consecutive patients who underwent aortic repair for acute type A aortic dissection from June 2007 to December 2018 at our centre. Of these, 139 patients underwent total arch replacement with FET (FET group), and 287 underwent other procedures (no FET group). Ninety-two patients in the FET group were matched to 92 patients in the no FET group by using propensity score matching analysis. RESULTS Thirty-day mortality and neurological dysfunction were not significantly different between the FET and no FET groups (1.4% vs 2.4%, P = 0.50 and 5.0% vs 6.3%, P = 0.61, respectively). Long-term survival was better in the FET group than in the no FET group (P = 0.008). Freedom from distal thoracic reintervention was similar in the FET and no FET groups (P = 0.74). In the propensity-matched patients, freedom from aortic-related death was better in the FET group than in the no FET group (P = 0.044). CONCLUSIONS Operative outcomes showed no significant difference between the 2 groups. FET contributes to better long-term survival in patients with acute type A aortic dissection.

Abstract OBJECTIVES Our goal was to determine the early and midterm outcomes after total arch replacement with the frozen elephant trunk (FET) technique compared to those of the conventional elephant trunk (ET) technique for acute retrograde type A aortic dissection. METHODS Between 2012 and 2019, a total of 49 patients had total arch replacement for acute retrograde type A aortic dissection. Patients were divided into the conventional ET (n = 17) and FET (n = 32) groups. The false lumen status was evaluated using enhanced computed tomography (CT) 1 week postoperatively. The diameter of the downstream aorta was evaluated annually using CT. The median follow-up period was 29 months. RESULTS Preoperative data and neurological complications were not significantly different in the 2 groups. The diameter and length of the ET prosthesis were significantly larger and longer in the FET group. The overall early mortality rate was 10.2% (5/49) with no differences between the 2 groups. The mean follow-up period was significantly longer in the conventional ET group. The rates of freedom from aortic events at 3 years were significantly lower in the FET group. At the level of the distal arch, postoperative false lumen patency was significantly lower and the follow-up aortic diameter was significantly smaller in the FET group. CONCLUSIONS The FET technique facilitates false lumen thrombosis and aortic remodelling at the distal arch level, with fewer adverse aortic events during the follow-up period with acceptable early outcomes; however, these findings are exploratory and require investigation.
