The frozen elephant trunk (FET) technique has been increasingly used to treat complex pathologies of the aortic arch and the descending aorta, but there still is an ongoing discussion within the surgical community about the optimal indications.

Multicentre analysis of current strategies and outcomes in open aortic arch surgery: heterogeneity is still an issue.Urbanski PP1, Luehr M2, Di Bartolomeo R3, Diegeler A4, De Paulis R5, Esposito G6, Bonser RS7, Etz CD8, Kallenbach K9, RylskiB10, Shrestha ML11, Tsagakis K12, Zacher M4, Zierer A13.
OBJECTIVES:The study was conducted to evaluate, on the basis of a multicentre analysis, current results of elective open aortic arch surgery performed during the last decade.
METHODS:
Data of 1232 consecutive patients who underwent aortic arch repair with reimplantation of at least
one supra-aortic artery between 2004 and 2013 were collected from 11 European cardiovascular centres, and
retrospective statistical examination was performed using uni- and multi-variable analyses to identify predictors for 30-day mortality. Acute aortic dissections and arch surgeries not involving the supra-aortic arteries were not included.
RESULTS:Arch repair involving all 3 arch arteries (total), 2 arch arteries (subtotal) or 1 arch artery (partial) was performed in 956(77.6%), 155 (12.6%) and 121 (9.8%) patients, respectively. The patients' characteristics as well as the surgical techniques,including the method of cannulation, perfusion and protection, varied considerably between the clinics participating in the study. The in-hospital and 30-day mortality rates were 11.4 and 8.8% for the entire cohort, respectively, ranging between 1.7 and 19.0% in the surgical centres. Multivariable logistic regression analysis identified surgical centre, patient's age, number of previous surgeries with sternotomy and concomitant surgeries as independent risk factors of 30-day mortality. The follow-up of the study group was 96.5% complete with an overall follow-up duration of 3.3 ± 2.9 years, resulting in 4020 patient-years. After hospital discharge, 176 (14.3%) patients died, yielding an overall mortality rate of 25.6%. The actuarial survival after 5and 8 years was 72.0 ± 1.5% and 64.0 ± 2.0, respectively.

CONCLUSIONS:
The surgical risk in elective aortic arch surgery has remained high during the last decade despite the
advance in surgical techniques.
However, the patients' characteristics, numbers of surgeries, the techniques and the results varied considerably
among the centres.
The incompleteness of data gathered retrospectively was not effective enough to determine advantages of
particular cannulation, perfusion, protection or surgical techniques; and therefore,
we strongly recommend further prospective multicentre studies, preferably registries, in which all
relevant data have to be clearly defined and collected.
Open aortic arch surgery in chronic dissection with visceral arteries originating from different lumens.Urbanski PP1, Bougioukakis P2, Deja MA3, Diegeler A2, Irimie V2, Lenos A2, Zembala MO4.Author informationEur J Cardiothorac Surg. 2016 May;49(5):1382-90.OBJECTIVES:Surgical management of chronic aortic dissection is controversial, especially when the dissection extends into the abdominal aorta in which the visceral arteries originate from different lumens and is combined with aortic arch pathology necessitating surgery. The aim of the study was to evaluate the results of open surgery in this complex aortic pathology.
METHODS:Between June 2002 and 2015, a total of 17 patients (median age 57, range 32-76 years) necessitating complete arch replacement presented complex chronic dissection of the thoraco-abdominal aorta with the visceral arteries originating from different lumens. Fourteen patients (82%) had had previous cardiac surgery, which was performed on the proximal aorta in all but one because of acute type A dissection. Nine patients without considerable dilatation of the descending aorta received aortic arch replacement with distal resection of the dissection membrane, and 8 patients with progressive dilatation of the thoracic aorta underwent aortic arch and descending aorta replacement via clamshell approach.
RESULTS:No early (defined as 30-day, 90-day and in-hospital period) deaths, strokes or spinal cord injuries occurred. Only 1 patient (6%) presented

RESULTS:No early (defined as 30-day, 90-day and in-hospital period) deaths, strokes or spinal cord injuries occurred. Only 1 patient (6%) presented temporary neurological dysfunctions (delirium, agitation), which resolved completely before discharge, and an injury of the recurrent laryngeal nerve was documented in 2 patients (12%). Temporary dialysis was necessary in 1 case. The follow-up was complete for all patients. All but one patient, who died due to leukaemia 23 months after surgery, were alive at the last follow-up (median duration 33 months, range 2-118 months). No patient needed a reoperation or an intervention on the thoracic and/or abdominal aorta. Moreover, no noticeable progression of the chronic dissection in the downstream aorta was documented in any patient.
CONCLUSIONS:The results after conventional aortic arch repair with distal resection of the dissection membrane and, if necessary, with replacement of the

Objective analysis of midterm outcomes of conventional and hybrid aortic arch repair by propensity-
score matching.Hiraoka A1, Chikazawa G2, Totsugawa T2, Tamura K2, Ishida A2, Sakaguchi T2, Yoshitaka H2.
OBJECTIVE:The aim of this study is to evaluate the objective outcomes of conventional total aortic arch repair (CTAR) and hybrid arch repair by using propensity-score matching to reduce selection bias.
METHODS:Between January 2006 and April 2016, 470 consecutive patients underwent isolated aortic arch repair (excluding hemiarch or partial arch
reconstruction, and cases with concomitant cardiac surgeries) at a single cardiovascular institute. We categorized 337 total aortic arch
repair with antegrade cerebral perfusion under circulatory arrest as the CTAR group and 58 hybrid aortic arch repair (HAR) with thoracic endovascular aortic repair as the HAR group. Seventy-five patients with scheduled and staged thoracic
endovascular aortic repair after total aortic arch repair with elephant trunk were excluded. Then, we compared early and midterm outcomes between the propensity-matched group (43 CTAR vs HAR pairs).
RESULTS:There were no significant differences in 30-day and operative deaths between the CTAR and HAR groups (4.7% [2/43] vs 7.0% [3/43]; P = .4142 and 11.6% [5/43] vs 16.3% [7/43]; P = .5637). Although there were no significant differences in the incidences of other major complications,
permanent stroke was observed more frequently in the HAR group (0% [0/43] vs 11.6% [5/43]; P = .0064) compared with the
CTAR group. Matching analysis, however, revealed an equivalent 5-year survival rate between the CTAR and HAR groups (80.5% vs 59.9%; P = .1300).

Conclusions: Hybrid aortic arch replacement can be performed with good postoperative and midterm results in a cohort of old patients with significant comorbidity. With greater experience, early and midterm outcomes continue to improve. The hybrid arch technique may represent a technical advancement in the field of aortic arch surgery.
