Background: This study aimed to evaluate the early and long-term outcomes of a single center using a frozen elephant trunk (FET) procedure for chronic type B or non-A non-B aortic dissection.Methods: From February 2009 to December 2019, 79 patients diagnosed with chronic type B or non-A non-B aortic dissection who underwent the FET procedure were included in the present study. We analyzed operation mortality and early and long-term outcomes, including complications, survival and interventions.Results: The operation mortality rate was 5.1% (4/79). Spinal cord injury occurred in 3.8% (3/79), stroke in 2.5% (2/79), and acute renal failure in 5.1% (4/79). The median follow-up time was 53 months. The overall survival rates were 96.2, 92.3, 88.0, 79.8, and 76.2% at 1/2, 1, 3, 5 and 7 years, respectively. Moreover, 79.3% of patients did not require distal aortic reintervention at 7 years. The overall survival in the subacute group was superior to that in the chronic group (P = 0.047).Conclusion: The FET technique is a safe and feasible approach for treating chronic type B and non-A non-B aortic dissection in patients who have contraindications for primary endovascular aortic repair. The technique combines the advantages of both open surgical repair and endovascular intervention, providing comparable early and long-term follow-up outcomes and freedom from reintervention.

Abstract Background Open stented elephant trunk (SET) or SET with left subclavian artery (LSCA) to left common carotid artery (LCCA) bypass is proven to a potentially alternative treatment for complicated Stanford type B aortic dissection (TBAD). In the current study, we reported our experience with ten consecutive TBAD patients who underwent open SET. Methods Patients with complicated TBAD underwent open SET from May 2016 to November 2018 in our institution were included. Patients’ clinical data were obtained from the electronic medical record system, and long-term clinical outcomes were collected by telephone interviews or outpatient interviews. Results A total of ten patients with nine males and one female were included, and the average age was 47.3 (31–65) years. Increased D-dimer and fibrinogen degradation products were observed in all patients at admission, and two patients had renal insufficiency. The average postoperative mechanical ventilation time, length of stay in intensive care unit, and postoperative hospital length of stay were 46.9 (6.7–151.2) hours, 7.7 (4–17) days, and 15.7 (10–26) days. No postoperative death occurred. Acute kidney injury and other complications were observed, and they were recovered well when discharge. In long-term follow-up, computed tomography angiography indicated that aortas were completely well remodeled, and blood supply of the brachiocephalic trunks was normal without anastomotic complications. All patients lived well. Conclusion SET or SET with subclavian artery correction shows satisfactory clinical outcomes, and it could be considered as an alternative treatment. Well-designed, large-scale studies with long-term follow-up are still needed.

Purpose: To report a case who required a thoracic endovascular stenting (TEVAR) following the deployment of frozen elephant trunk due to false lumen expansion Case Report: A 47 years old male patient undergone emergency repair of acute type A aortic dissection in 2011 with bioprosthetic aortic root conduit. Seven years later he presented with moderate aortic valve disease and expanding chronic dissection of the aortic arch, therefore a redo operation with replacement of the prosthetic aortic valve, ascending aorta, total arch and deployment of frozen elephant trunk and he was discharged in good health. Several days post discharge he presented with new onset of chest pain and a new dissection involved the thoracoabdominal aorta was noted pressing on the true lumen and the frozen elephant trunk. Following a multi-disciplinary team meeting, TEVAR was deemed as a most appropriate approach and this was achieved successfully, and patient was discharged. At 1 year of follow up, he remains well and asymptomatic. Conclusion: Close imaging follow-up following deployment of a FET is mandatory. A new acute Type B aortic dissection distal to the FET, that causes false lumen propagation parallel to the stented portion, is a surgical emergency and further intervention mandated.

Abstract OBJECTIVES The aim of this study was to investigate the clinical outcomes and follow-up results among 5 main aortic arch surgery methods for type A aortic dissection in a single centre. METHODS From 2002 to 2018, 958 type A aortic dissection patients who received surgical repair were divided into 5 groups according to the arch surgery method: hemiarch replacement (n = 206), island arch replacement (n = 54), total arch replacement with frozen elephant trunk (n = 425), triple-branched stent (n = 39) and fenestrated stent (n = 234). The indications for the different arch methods were related to the patient’s preoperative status, the location and extent of the dissection and the surgical ability of the surgeons. A comparative study was performed to identify the differences in the perioperative data, and the Kaplan–Meier analysis was used to assess the long-term survival and reintervention rates. Thirty matched surviving patients that were included in each group completed Computed tomography angiography to determine long-term reshaping effect. RESULTS The 30-day mortality rate was 15.8%, and there was no difference among the 5 groups (P = 0.848). The follow-up survival rates were similar among the 5 groups (P = 0.130), and the same was true for patients without reintervention (P = 0.471). In the propensity matching study, patients with stents (frozen elephant trunk, triple-branched stent, fenestrated stent) had a slower aortic dilation rate and a higher ratio of thrombosis in the false lumen at the descending aortic and abdominal aortic levels than patients without stents. CONCLUSIONS No standard method is available for arch surgery, and indications and long-term effects should be identified with clinical data. In our experiences, simpler surgical procedures could reduce mortality in critically ill patients and stents in the distal aorta could improve long-term reshape effects.
