The outcomes of aortic arch repair between open surgical repair and debranching endovascular hybrid surgical repair: A systematic review and meta-analysis. J Vasc Surg 2024; 79:1510-1524. [PMID: 38122857 DOI: 10.1016/j.jvs.2023.12.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 11/26/2023] [Accepted: 12/10/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND At present, open surgical aortic arch repair (OAR) and debranching hybrid surgical aortic arch repair (HAR) serve as significant therapeutic approaches for aortic arch aneurysm or dissection. It remains unclear which technique is preferable. Our study aimed to compare the short-term and long-term outcomes of these two procedures. METHODS To identify comparison studies of debranching HAR and OAR, a systematic search of the PubMed, Embase, Web of Science, and Cochrane Library databases was performed from January 2002 to April 2022. This study was registered on PROSPERO (CRD42020218080). RESULTS Sixteen publications (1316 patients), including six propensity score-matching (PSM) analysis papers, were included in this study. Compared with the HAR group, the patients who underwent OAR were younger (OAR vs HAR: 67.53 ± 12.81 vs 71.29 ± 11.0; P < .00001), had less coronary artery disease (OAR vs HAR: 22.45% vs 32.6%; P = .007), less chronic obstructive pulmonary disease (OAR vs HAR: 16.16% vs 23.92%; P = .001), lower rates of previous stroke (OAR vs HAR: 12.46% vs 18.02%; P = .05), and a lower EuroSCORE (European System for Cardiac Operative Risk Evaluation) score (OAR vs HAR: 6.27 ± 1.04 vs 6.9 ± 3.76; P < .00001). HAR was associated with less postoperative blood transfusion (OAR vs HAR: 12.23% vs 7.91%; P = .04), shorter length of intensive care unit stays (OAR vs HAR: 5.92 ± 7.58 days vs 4.02 ± 6.60 days; P < .00001) and hospital stays (OAR vs HAR: 21.59 ± 17.54 days vs 16.49 ± 18.45 days; P < .0001), lower incidence of reoperation for bleeding complications (OAR vs HAR: 8.07% vs 3.96%; P = .01), fewer postoperative pulmonary complication (OAR vs HAR: 14.75% vs 5.02%; P < .0001), and acute renal failure (OAR vs HAR: 7.54% vs 5.17%; P = .03). In the PSM subgroup, the rates of spinal cord ischemic (OAR vs HAR: 5.75% vs 11.49%; P = .02), stroke (OAR vs HAR: 5.1% vs 17.35%; P = .01), and permanent paraplegia (OAR vs HAR: 2.79% vs 6.08%; P = .006) were lower in the OAR group than that in the HAR group. Although there was no statistically significant difference in 1-year survival rates (HAR vs OAR: hazard ratio [HR]: 1.54; P = .10), the 3-year and 5-year survivals were significantly higher in the OAR group than that in the HAR group (HAR vs OAR: HR: 1.69; P = .01; HAR vs OAR: HR: 1.68; P = .01). In the PSM subgroup, the OAR group was also significantly superior to the HAR group in terms of 3-year and 5-year survivals (HAR vs OAR: HR: 1.73; P = .04; HAR vs OAR: HR: 1.67; P = .04). The reintervention rate in the HAR group was significantly higher than that in the OAR group (OAR vs HAR: 8.24% vs 16.01%; P = .01). The most common reintervention was postoperative bleeding (8.07%) in the OAR group and endoleak (9.67%) in the HAR group. CONCLUSIONS Our meta-analysis revealed that debranching HAR was associated with fewer perioperative complications than the OAR group, except for postoperative permanent paraplegia, reintervention, and stroke events. The OAR group demonstrated better 3-year and 5-year survivals than the debranching HAR group. However, patients in the OAR group had fewer comorbid factors and were younger than those in the HAR group. High-quality studies and well-powered randomized trials are needed to further evaluate this evolving field.

[PMID: 38822182 DOI: 10.1007/s11748-024-02043-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Accepted: 05/18/2024] [Indexed: 06/02/2024]
Abstract
OBJECTIVES The aim of this study is to analyze long-term results of the total aortic arch replacement with the frozen elephant trunk technique for primary chronic type B aortic dissection. METHODS Among 322 patients who had the frozen elephant trunk technique, 43 (13.4%) patients (median age, 64.0 years) with primary chronic type B aortic dissection were analyzed. The patients underwent surgery at a median of 27.0 months after the onset of aortic dissection. The false lumen was patent in 30 (69.8%) patients preoperatively. RESULTS Two patients suffered paraplegia and another died of cerebral infarction. Complete thrombosis of the peri-stent false lumen was achieved in 36 (83.7%) patients. Overall survival, freedom from aortic events, and freedom from aortic reintervention were 83.5%, 37.2%, and 42.2% at 5 years, respectively. Survival rates of the patients with or without aortic events were 75.0% and 95.8% at 5 years (Log-rank, p = 0.22). Late aortic events occurred in 19 (44.2%) patients including distal stent graft-induced new entry, type Ib endoleak, and false lumen dilation. The ratio of the stent graft diameter to the preoperative short axis diameter of the true lumen (hazard ratio, 1.90; 95% confidence interval, 1.01-3.59), and the maximal diameter of a postdissection aneurysm (1.07; 1.01-1.12) were the significant multivariate risk predictors of late aortic events. CONCLUSIONS Late aortic events occurr fairly frequently, and new strategies need to be explored to enhance the effectiveness of this procedure in the future.

Abstract
BACKGROUND This study aims to identify the risk factors contributing to spinal cord injury (SCI) following a type A acute aortic dissection (TA-AAD). METHODS This retrospective study was conducted at a single center and involved 481 patients who received frozen elephant trunk stent implantation for TA-AAD. Additionally, these patients underwent total arch replacement with deep hypothermic circulatory arrest. This study was performed at Fuwai Hospital between September 2016 and April 2020. RESULTS The resulting data of the multivariate logistic regression analysis demonstrated that preoperative platelet count (odds ratio [OR] = 0.774) and D-dimer levels (OR = 2.247) could serve as independent predictors for postoperative SCI in patients with TA-AAD. CONCLUSION The findings indicate that preoperative platelet count and D-dimer levels are independent risk factors for postoperative SCI in patients with TA-AAD. This study holds significant clinical implications regarding the prognosis and therapeutic responses for patients with TA-AAD.

Abstract
OBJECTIVE Spinal cord injury (SCI) with subsequent paraplegia and/or stroke after arch repair with frozen elephant trunk (FET) remain the most devastating complications. In this study, we aim to examine the impact of different cerebral perfusion strategies on the neurological outcome comparing bilateral antegrade cerebral perfusion (bACP) and trilateral antegrade cerebral perfusion (tACP). METHODS Between 2009 and 2021, 88 patients underwent total arch replacement using a hybrid prosthesis in FET technique for acute (40.4%) and chronic (59.6%) aortic pathologies. After excluding 14 patients who underwent FET with unilateral ACP the remaining 74 patients were divided into two groups. Propensity score matching was performed based on pre- and perioperative patient characteristics resulting in 22 patients in each group. The primary endpoint was a combination of major cerebral event and SCI. Secondary end point was all-cause mortality. RESULTS Major cerebral events occurred in 9% of the patients in bACP versus 13.6% in tACP group (p = 0.63). No postoperative SCI was observed in patients with bACP and only one patient suffered SCI with tACP (p = 0.31). There was no significant difference in 30-day mortality between the two groups (22.7% in bACP vs. 13.6% in tACP; p = 0.43). CONCLUSION In patients undergoing total aortic arch repair using FET technique, both perfusion strategies (bilateral and trilateral ACP) are safe and effective. The rates of neurological complications as well as mortalities are acceptably low in both groups. Further studies with larger patient cohorts are warranted.

Abstract
OBJECTIVES To investigate the optimal stent length and distal positioning of frozen elephant trunks (FETs) in patients with type A acute aortic dissection (TAAD). METHODS Between October 2014 and April 2021, 191 patients (FET-150 group: 37 patients; stent length, 150 mm; 66.3 ± 12.6 years and FET-non-150 group: 154 patients; 60, 90, or 120 mm; 64.1 ± 12.5 years) underwent total arch repair with FETs for TAAD using the "zone 0 arch repair" strategy. In the FET-150 group, the proximal stent end was positioned at the innominate artery origin of the arch. In the FET-non-150 group, the distal stent end was to be positioned just proximal to the aortic valve level using transesophageal echocardiography. The proximal end of the non-stented FET part was sutured to an arch graft together with the aortic wall at 1 to 2 cm proximal to the innominate artery origin. RESULTS Distal stent ends were positioned at the thoracic vertebrae (Th) 4-5, 6-7, 8-9, and 10 levels in 0 (0%), 12 (32.4%), 25 (67.6%), and 0 (0%) patients, respectively, in the FET-150 group, and in 6 (3.9%), 98 (63.6%), 49 (31.8%), and 1 (0.7%), respectively, in the FET-non-150 group. No between-group difference in postoperative mortality was noted. The incidence of postoperative residual distal malperfusion and new-onset spinal cord ischemia in the FET-150 versus FET-non-150 groups were 2.7% versus 6.5% (P = .62) and 0% versus 1.9% (P = 1.00), respectively. CONCLUSIONS FET positioning with the distal stent end at around Th 8 can reduce residual distal malperfusion when a FET with a 150-mm stent is deployed from the aortic zone 0 in patients with TAAD undergoing total arch repair.

Abstract
Objective To investigate the association between false lumen (FL) dependency of segmental arteries (SAs) at T9-L3 levels and the risk of spinal cord injury (SCI) following total arch replacement and frozen elephant trunk (FET) implantation in the setting of acute DeBakey type I aortic dissection (AAD). Methods The study involved consecutive patients with AAD who underwent total arch replacement and FET implantation between 2020 and 2022. Primary outcome was postoperative SCI. The inverse probability of treatment weighting (IPTW) method was employed to minimize the impact of no-randomization bias. Antegrade placement of FET was followed by end-to-end anastomosis of a 4-branch arch graft at the proximal landing site of FET. Results A total of 146 patients were included (age, 50.5 ± 11.7 years, 115 male), of whom 35 (24%) had SAs at T9-L3 levels completely dependent on FL (FL-dependency group). There was no significant difference in early (30-day or in-hospital) mortality rates between FL-dependency (14.3%) and FL-independency (18.0%) groups (P = .80), however, the rate of SCI was significantly higher in the FL-Dependency group (34.3% vs 2.7%, P < .001). After adjustments, FL dependency was associated with a significantly increased risk of SCI (odds ratio, 13.1; 95% confidence interval, 4.2-41.0; P < .001), whereas it was not significantly associated with risks of early mortality or other major complications (P = .16-.98). Conclusions FL dependency of SAs at the T9-L3 levels was significantly associated with the development of SCI following FET implantation in AAD, warning against its uses on patients presenting with FL dependency of SAs at critical segments.

Abstract
BACKGROUND The initial goal of acute Type A aortic dissection (ATAAD) repair remains to get the patient off the table safely. More extensive repair is being pushed at the index operation with the frozen elephant trunk (FET) operation, but outcomes are suggested to be worse. However, we hypothesize that the risk associated with the FET in ATAAD is from the patient presenting factors rather than the operation itself. METHODS A retrospective review of a single institution prospective database from 2015 to 2021 was performed. Two cohorts were created based on the indication for FET: evidence of radiographic malperfusion (n = 44) or clinical malperfusion (n = 31). Data were analyzed for preoperative characteristics, intraoperative characteristics, and postoperative outcomes. Statistical univariate analysis was performed with chi-square analysis and t-tests with significance determined at an alpha level of 0.05. RESULTS Preoperative characteristics were similar in each group, independent of malperfusion markers. The intraoperative characteristics were similar, except the clinical malperfusion group had more packed red blood cells and cryoprecipitate given. The clinical malperfusion group had longer intensive care unit length of stay (p < 0.001), more postoperative strokes (p < 0.001), more reoperations (p <0.0001), and higher mortality rate (p = 0.0003). CONCLUSION These data suggest that clinical malperfusion increases the risk of major complications and death. However, full arch replacement with FET in the absence of clinical malperfusion does not appear to add risk to the operation for ATAAD. Patients with increased risk of distal degeneration should be considered for more aggressive replacement to avoid subsequent arch replacement.

Abstract
BACKGROUND The optimal treatment for acute non-A-non-B aortic dissection remains controversial. Triple-branched stent graft (TBSG) implantation has been used to treat acute type A aortic dissection. This study aimed to evaluate the safety and efficacy of TBSG as a treatment for acute non-A-non-B aortic dissection. METHODS Fifty patients with non-A-non-B dissection received TBSG implantation in our center between January 2014 and December 2019. Early mortality, morbidity, and dissected aorta remodeling during follow-up were calculated. RESULTS There were no deaths in-hospital or within 30 days. Postoperative complications included pneumonia (n = 12), acute kidney injury (n = 6; preoperative renal malperfusion, n = 4), transient cerebral injury (n = 6; preoperative cerebral malperfusion, n = 4), pleural effusion (n = 4), and pericardial effusion (n = 2). During follow-up, 1 patient experienced a stroke, and 2 patients required secondary interventional therapy for residual dissection below the level of the TBSG. All implanted TBSGs had good positioning, and all sidearm stent graft grafts were fully patent. No retrograde aortic dissection or type I endoleak was detected. CONCLUSIONS TBSG implantation for acute non-A-non-B aortic dissection had a low incidence of mortality and morbidity, featuring good remodeling of the dissected aortic wall during follow-up. The early outcomes of this technique were satisfactory.

Abstract
Single-stage extended replacement from the ascending to the distal descending aorta or beyond is a formidable operation that should be preserved for those who have no other option or those who are physically fit, and should be performed in the experienced centers. Hybrid operations combining open surgical repair with thoracic endovascular aortic repair through a median sternotomy incision are preferable because these operations are less invasive than the extended open aortic repair and the risk of spinal cord ischemia is lower compared with the frozen elephant trunk operation. However, these operations are associated with the inherent demerits of endovascular aneurysm exclusion. When the underlying aortic pathology necessitates extended open aortic repair in a single stage, approaches such as the anterolateral partial sternotomy, straight incision with rib cross, and extended thoracotomy with sternal transection may be useful to provide sufficient exposure for both aortic reconstruction and organ protection, with less surgical stress to the patients.

Abstract
The frozen elephant trunk (FET) technique is useful in the single-stage treatment of aortic arch aneurysms. Since there is no established implantation method for evaluating the distal end of the FET during surgery, we propose the FET positioning method using the ostium of the coronary artery on transesophageal echocardiography (TEE) as an index. We performed 11 total arch replacement operations using an FET for aortic arch aneurysm. The planned position of the FET was determined by computed tomography (CT), and the distance to the ostium of the coronary artery was measured. Intraoperatively, using TEE as a guide, the FET was implanted using our method. Postoperative CT was evaluated the distance from the planned FET position, and the average and median difference was only 0.96 cm and 0.6 cm, respectively. TEE-guided FET deployment using the coronary artery ostium as an index is a simple and reproducible technique.

Abstract
Introduction Kinking of the Frozen Elephant Trunk (FET) stent graft is one of the most devastating complications of the FET procedure. It can present post-operatively with reduced arterial pressures in the lower limbs and intermittent claudication. However, it can also be visualized intra-operatively by the surgeons. Unresolved kinking of the stent graft can result in intraluminal thrombus formation and subsequent multi-organ septic emboli. Aims The main scope of this review is to collate, summarize and present all the evidence in the literature on kinking of FET stent grafts. Methods We carried out a comprehensive literature search on multiple electronic databases including PubMed, EMBASE, Ovid, and Scopus to collate all research evidence on the incidence, mechanism, and management of FET graft kinking. Results Incidence of kinking is variable, ranging from 0% to 8% in the literature, with varying rates associated with each stent graft type. The Thoraflex HybridTM prosthesis seemed to be the most commonly used and superior graft, and out of all the 15 cases of kinking reported in the literature, 5 (33.3%) were associated with just the Frozenix graft which had the highest incidence. There are multiple theories regarding the mechanism of kinking, including the direction of blood flow, the length of the stent grafts used, and the position of the prosthesis in relation to the flexure of the aorta. Multiple reparative management techniques have been suggested in the literature and include total endovascular repair, open repair, balloon dilatation, and deploying a second stent graft. Conclusion Graft kinking is one of the most critical complications of the FET technique. Its life-threatening sequelae warrant appropriate follow-up of these patients post-operatively, in addition to time management if kinking is suspected. Given the limited evidence in the literature, future studies should incorporate graft kinking into their outcomes reporting.

Abstract
OBJECTIVES Since selective cerebral perfusion (SCP) has been used in aortic arch surgical procedures, the core temperature during lower body circulatory arrest (LBCA) has been steadily rising. Simultaneously, the use of a frozen elephant trunk (FET) graft has been increasing. The safe period of LBCA in relation to spinal cord ischaemic tolerance in combination with segmental artery occlusion by the FET procedure has not been defined. METHODS Sixteen pigs were assigned to undergo 65 (n = 10) or 90 min (n = 6) of SCP at 28°C with LBCA in combination with occlusion of the 8 uppermost segmental arteries in the thoracic (Th) aorta (15-20 cm FET, Th8-level). The follow-up period consisted of a 6-h intensive period and a 5-day observation period. Near-infrared spectroscopy of the collateral network was used to determine spinal cord oxygenation. The neurological status of the patients was evaluated daily, and the brain and the spinal cord were harvested for a histopathological analysis. RESULTS Five out of 6 pigs after 90 min and 1 out of 10 pigs after 65 min of LBCA died within 48 h of multiorgan failure. Of the survivors in the 65-min group, 6 out of 9 had paraparesis/paraplegia; the remaining 3 reached normal function. The lone survivor after 90 min of LBCA was paraplegic. Nadir near-infrared spectroscopy of the collateral network values at Th8 and Th10 were 34 (±5) and 39 (±4), and they were reached within 35 min of SCP in both groups. CONCLUSIONS An extended FET graft with LBCA and SCP durations >65 min at 28°C results in a poor outcome.

Abstract
Background and Aim of the Study To report early clinical outcomes of the frozen elephant trunk (FET) technique for the treatment of complex aortic diseases after transition from conventional elephant trunk. Methods A single‐center, retrospective study of patients who underwent hybrid aortic arch and FET repair for aortic arch and/or proximal descending aortic aneurysms, acute and chronic Stanford type A aortic dissection with arch and/or proximal descending involvement, Stanford type B acute and chronic aortic dissections with retrograde aortic arch involvement. Results Between December 2017 and May 2020, 70 consecutive patients (62.7 ± 10.6 years, 59 male) were treated: 41 (58.6%) for emergent conditions and 29 (41.4%) for elective. Technical success was 100%. In‐hospital mortality was 14.2% (n = 12, 17.1% emergent vs. 10.3% elective, P = NS); 2 (2.9%) major strokes; 1 (1.4%) spinal cord injury. Mean follow‐up was 12.5 months (interquartile range, 3.7–22.3). Overall survival at 3, 6, 12, and 24 months was 90% (95% confidence interval [CI], 83.2—97.3), 85.6% (95% CI, 77.7–94.3), 79.1% (95% CI, 69.9–89.5), 75.6% (95% CI, 65.8–86.9) and 73.5% (95% CI, 63.3–85.3). There were no aortic re‐interventions and no distal stent graft‐induced new entry (dSINE); 5 patients with residual type B dissection underwent TEVAR completion. Conclusions In a real‐world setting, FET with Thoraflex Hybrid demonstrated feasibility and good clinical outcomes, even in emergent setting. Our implant technique optimize cerebral perfusion reporting good results in terms of neurological complications. Techniques to perfect the procedure and to reduce remaining risks, and consensus on considerations such as standardized cerebral protection need to be reported.

Abstract
PURPOSE Hybrid aortic arch repair (HAR) has been implemented for extended aortic arch and descending thoracic aortic disease since 2012 in our institution. This study aimed to estimate the early and mid-term efficacy and safety of HAR. MATERIALS AND METHODS From 2007 to 2019, 56 patients underwent HAR for extended aortic arch disease, and 75 patients underwent total arch replacement (TAR) for arch-limited disease. HAR comprises 3 procedures: replacement of the aorta, reconstruction of all arch vessels, and thoracic endovascular aortic repair (TEVAR) from zone 0 to the descending aorta after cardiopulmonary bypass is off in 1 stage. The type II-1 HAR procedure, in which the ascending aorta and aortic arch distal to the brachiocephalic artery are replaced, was the most frequently selected procedure (40/56 patients). The outcomes of the type II-1 HAR procedure were compared with those of TAR using the Cox regression analysis. RESULTS The median follow-up period was 36 months. In HAR, the operative mortality, in-hospital mortality, and postoperative permanent neurological deficits were not observed. The paraplegia rate was 1.8%. TEVAR-related complications occurred in 3 patients. Among the patients with non-ruptured atherosclerotic aortic arch aneurysm (31 type II-1 HAR patients and 36 TAR patients, the postoperative respiratory support time in those who underwent type II-1 HAR was quicker than in those who underwent TAR (p<0.01). The rate of 6 year freedom from all-cause death in type II-1 HAR (83.1%) was numerically higher than that in TAR (74.7%), and the rate of 6 year freedom from surgery-related complications in type II-1 HAR (90.3%) was numerically lower than that in TAR (96.9%) due to the occurrence of TEVAR-related complications, and the rate of 6 year freedom from reintervention to the descending thoracic aorta in type II-1 HAR (100%) seemed to be better than that in TAR (83.7%). However, Cox regression analysis did not reveal any statistical difference between the 2 procedures. CONCLUSIONS HAR, especially the type II-1 procedure, can treat extended aortic arch disease with acceptable survival outcomes. The development of TEVAR technology will further improve the outcomes of HAR in the future.

Abstract
OBJECTIVES We investigated the effect of a preoperative age ≥80 years on postoperative outcomes in patients who underwent isolated elective total arch replacement using mild hypothermic lower body circulatory arrest with bilateral antegrade selective cerebral perfusion. METHODS A total of 140 patients who had undergone isolated elective total arch replacement between January 2007 and December 2020 were enrolled in the present study. We compared postoperative outcomes between 30 octogenarian patients (≥80 years old; Octogenarian group) and 110 non-octogenarian patients (≤79 years old; Non-Octogenarian group). RESULTS Overall 30-day mortality and hospital mortality were 0% in both groups, and there was no significant difference in overall survival between the 2 groups (log-rank test, P = 0.108). Univariable Cox proportional hazard analysis showed that age as continuous variable was only the predictor of mid-term all-cause death (hazard ratio 1.08, 95% confidence interval 1.01–1.16; P = 0.037), but not in the Octogenarians subgroup (P = 0.119). CONCLUSIONS Preoperative age ≥80 years is not associated with worse outcomes postoperatively after isolated elective total arch replacement with mild hypothermic lower body circulatory arrest and bilateral antegrade selective cerebral perfusion.

Abstract
OBJECTIVE The purpose of this study was to assess our early experience with the Thoraflex hybrid prosthesis. Design. This was a retrospective, single-center cohort study. RESULTS Between December 2014 and December 2019, 34 patients underwent total aortic arch replacement with the Thoraflex hybrid prosthesis. Fifteen of the patients had pre-operative chronic aortic dissection. The mean cardiopulmonary bypass time was 200 ± 35 min, aortic cross clamp time 114 ± 34 min, deep circulatory arrest time to the lower body 60 ± 22 min, and selective antegrade cerebral perfusion time 67 ± 24 min. The rate of stroke was 11.7% (4/34), paraparesis was 8.8% (3/34) and renal failure was 11.7% (4/34). No patient required permanent dialysis. Three (8.8%) patients died within the first 30 days postoperatively. All early deaths were due to stroke or spinal cord complications. During follow-up, an additional four patients died. Average follow-up was 32.4 ± 19.4 months (1102 patient-months) and was 100% complete. Survival at 12 months and 36 months was 88% ± 7.2% and 75% ± 12.7%, respectively. CONCLUSIONS The Thoraflex hybrid prosthesis can be used in the setting of total aortic arch replacement with good early- and medium-term results. Stroke and spinal cord complications remain an important source of early mortality.

Tsutsumi K, Ishida O, Yamanaka N, Hayashi K, Hashizume K. Total aortic arch replacement using the J-graft open stent graft for distal aortic arch aneurysm: report from two centres in Japan. Interact Cardiovasc Thorac Surg 2021; 33:614-621. [PMID: 34329416 DOI: 10.1093/icvts/ivab114] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 03/03/2021] [Accepted: 03/22/2021] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVES The open-style stent graft technique has been changing the strategy for true distal arch aneurysms extending to the descending aorta. Our mid-term results of surgical repair using a J-graft open stent graft are presented. METHODS Between May 2015 and June 2020, 69 patients with a distal arch aneurysm (53 males, median age 74 years) underwent total arch replacement combined with J-graft open stent deployment. All 59 surviving patients were followed for a median follow-up period of 1.8 (0.6-3.6) years. RESULTS Antegrade deployment was successfully performed in all patients without any difficulties. The deployed device was securely fixed at the target area, and it initiated thrombus formation. The diameter of the excluded aneurysm was decreased in 54 patients (91.5%) during the follow-up period. There were no type I endoleaks, but there were 3 type II endoleaks; 2 of the 3 type II endoleaks disappeared during the follow-up period. Additional endovascular operations were performed in 3 patients. There were 10 in-hospital deaths (14.5%), and the incidences of stroke, spinal cord injury and distal embolism were 11.6%, 5.8% and 2.9%, respectively. The 1- and 3-year survival rates were 84.8% and 79.4%, respectively, and the 1- and 3-year freedom from reintervention rates were 97.2% and 81.3%, respectively. CONCLUSIONS The J-graft open stent graft was easy to deploy, and it could shift the distal anastomosis to a more proximal side. The mid-term performance of this device was good. It has the potential to provide one-stage repair.

Abstract
OBJECTIVE To identify predictors of aortic aneurysm formation at or above an infrarenal abdominal aortic aneurysm repair. METHODS A total of 881 infrarenal abdominal aortic aneurysm repairs were identified at a single institution from 2004 to 2008; 187 of the repairs were identified that had pre-operative and post-operative computed tomography imaging at least one year or greater to evaluate for aortic degeneration following repair. Aortic diameters at the celiac, superior mesenteric, and renal arteries were measured on all available computed tomographic scans. Aortic thrombus and calcification volumes in the visceral and infrarenal abdominal aortic segments were calculated. Multivariable modeling was used with log transformed variables to determine potential predictors of future aortic aneurysm development after infrarenal abdominal aortic aneurysm repair. RESULTS Of the 187 patients in the cohort, 100 had an open abdominal aortic aneurysm repair while 87 were treated with endovascular repair. Proximal aortic aneurysms developed in 26% (n = 49) of the cohort during an average of 72 ± 34.2 months of follow-up. After multivariable modeling, visceral segment aortic thrombus on pre-operative computed tomography imaging increased the risk of aortic aneurysm development above the infrarenal abdominal aortic aneurysm repair within both the open abdominal aortic aneurysm (hazard ratio 2.04, p = 0.033) and endovascular repair (hazard ratio 3.31, p = 0.004) cohorts. Endovascular repair was independently associated with a higher risk of future aortic aneurysm development after infrarenal abdominal aortic aneurysm repair when compared to open abdominal aortic aneurysm (hazard ratio 2.19, p = 0.025). CONCLUSIONS Visceral aortic thrombus present prior to abdominal aortic aneurysm repair and endovascular repair are both associated with an increased risk of future proximal aortic degeneration after infrarenal abdominal aortic aneurysm repair. These factors may predict patients at higher risk of developing proximal aortic aneurysms that may require complex aortic repairs.

Abstract
OBJECTIVES The frozen elephant trunk (FET) technique has become an important tool in the treatment of acute type A aortic dissection. The aim of this study was to evaluate the effect of long FET on spinal cord injury (SCI) and distal aortic remodeling after acute type A aortic dissection based on clinical and radiological outcomes. METHODS From January 2018 to November 2019, 158 patients (mean age 51.8 years [range: 32-78 years], 88.6% male) with acute type A aortic dissection were treated by FET with 100 mm (n = 113) or 150 mm (n = 45) open hybrid stent graft prosthesis. Patients were divided into two groups according to the length of FET. The clinical and radiological outcomes of the patients were reviewed retrospectively. RESULTS Postoperative outcomes did not differ significantly: in-hospital mortality (9.7% vs. 6.7%, p = .758) and SCI (5.3% vs. 2.2%, p = .674). Aortic remodeling, which was evaluated by aortic diameter, true lumen diameter, false lumen (FL) diameter and the rate of FL complete thrombosis, was more positive in long FET group in the descending thoracic aorta during the follow-up period. At the abdominal level, there was no statistically significant difference between the two groups. CONCLUSIONS The long version of FET does not increase the risk of SCI in patients with acute type A aortic dissection. The application of long FET can achieve better results in terms of remodeling of the thoracic aorta in the short- and medium-term follow-up.

Abstract
BACKGROUND The treatment of complex thoracic aorta pathologies remains a challenge for cardiovascular surgeons. After introducing Frozen Elephant Trunk (FET), a significant evolution of surgical techniques has been achieved. The present meta-analysis aimed to assess the efficacy of FET in acute type A aortic dissection (ATAAD) and the effect of circulatory arrest time on post-operative neurologic outcomes. METHODS A standard Preferred Reporting Items for Systematic Reviews and Meta-Analyses search was conducted for all observational studies of patients diagnosed with ATAAD undergoing total arch replacement with FET reporting in-hospital mortality, bleeding, and neurological outcomes. A random-effect meta-analysis was performed using STATA software (StataCorp, TX, USA). RESULTS Thirty-five studies were eligible for the present meta-analysis, including 3211 patients with ATAAD who underwent total arch replacement with FET. The pooled estimate for in-hospital mortality, postoperative stroke, and spinal cord injury were 7% (95% CI 5 - 9; I2 = 68.65%), 5% (95% CI 4 - 7; I2 = 63.93%), and 3% (95% CI 2 - 4; I2 = 19.56%), respectively. Univariate meta-regression revealed that with increasing the duration of hypothermic circulatory arrest time, the effect sizes for postoperative stroke and SCI enhances. CONCLUSIONS It seems that employing the FET procedure for acute type A dissection is associated with acceptable neurologic outcomes and a similar mortality rate comparing with other aorta pathologies. Besides, increasing hypothermic circulation arrest time appears to be a significant predictor of adverse neurologic outcomes after FET.

Abstract
OBJECTIVE We performed a multicenter prospective comparative study to determine the impact of a Japanese frozen elephant trunk device on total arch replacement compared with conventional repair without it. METHODS Between 2016 and 2019, a total of 684 patients (frozen elephant trunk procedure; n = 369; conventional repair, n = 315) from 41 institutions were enrolled. The 2 procedures were selected according to each center's strategy. RESULTS The frozen elephant trunk procedure was applied more for aortic dissection, whereas the conventional repairs were predominantly performed for aneurysms. In the former, only hypothermic circulatory arrest time was reduced among the intraoperative parameters. Although there were no differences in the 30-day and in-hospital mortality rates (0.8% and 1.6%, respectively, for the frozen elephant trunk procedure vs 0.3% and 0.6%, respectively, for conventional repair), the neurologic complication rates were significantly higher in stroke (5.7% vs 2.2%; P = .022) and paraplegia (1.6% vs 0%; P = .023). In the propensity score matching analyses using 11 variables, statistical significance disappeared in the differences for mortality and neurologic morbidity (stroke and paraplegia/paraparesis) rates of 194 patients of each group, although they were still higher for the frozen elephant trunk procedure. CONCLUSIONS The early outcomes of total arch replacement with the frozen elephant trunk procedure were acceptable despite its higher prevalence of emergency or redo surgery, which was comparable to that of the conventional repair. This procedure had higher rates of spinal cord injury than the conventional repair, which is a disadvantage of this approach.

Abstract
Over the decades, the Frozen Elephant Trunk (FET) technique has gained immense popularity allowing simplified treatment of complex aortic pathologies. FET is frequently used to treat aortic conditions involving the distal aortic arch and the proximal descending aorta in a single stage. Surgical preference has recently changed from FET procedures being performed at Zone 3 to Zone 2. There are several advantages of Zone 2 FET over Zone 3 FET including reduction in spinal cord injury, visceral ischemia, neurological and cardiovascular sequelae. In addition, Zone 2 FET is a technically less complicated procedure. Literature on the comparison between Zone 3 and Zone 2 FET is scarce and primarily observational and anecdotal. Therefore, further research is warranted in this paradigm to substantiate current surgical treatment options for complex aortic pathologies. In this review, we explore literature surrounding FET and the reasons for the shift in surgical preference from Zone 3 to Zone 2.

Abstract
Aortic diseases located in the ascending aorta, aortic arch or proximal descending aorta often require more than one surgical intervention depending on the type of pathology and its extent as well as future anticipated aortic problems. These obstacles were tackled in 1983 by Hans Borst with the introduction of the classic elephant trunk (cET). This was an outstanding and straightforward procedure. Since then, the cET was very often the first surgical approach for patients with extensive aortic pathology of the ascending aorta and arch extending into the downstream aorta. Thirteen years later, Suto and Kato introduced the frozen elephant trunk (fET) which was later on perfectionized by industry and applied in various ways by many surgical groups worldwide. Comparing the cET with the fET raises a lot of difficulties. The lack of randomization and the presence of procedural and complication-related limitations for each technique do not allow for definitive conclusions about the ideal procedure to treat complex aortic pathology. It would be very short-sighted to close all future discussions about the subject with this statement of the Hannover group made in 2011. Since both techniques and its results cannot be compared statistically due to the heterogeneity of patient groups, the lack of randomization, the difference in type and extent of pathology, the differences in surgical techniques, the learning curve in gaining experience in both techniques, and the lack of reporting standards, no scientific conclusion can be drawn as to which technique is most successful. Comparisons may even be considered futile. It is the purpose of this paper merely to make a descriptive observation of both techniques, to discuss some important elements of interest and to give some constructive and useful criticism.

Abstract
OBJECTIVE The present study aimed to evaluate the outcomes of total aortic arch replacement with proximalization of distal anastomosis using the frozen elephant trunk technique with the J Graft FROZENIX (Japan Lifeline, Tokyo, Japan) and Gelweave Lupiae (Vascutek Terumo Inc, Scotland, United Kingdom) graft (distal anastomosis performed in zones 1 and 2) in patients with acute Stanford type A acute aortic dissection. METHODS A total of 50 patients underwent total aortic arch replacement using the frozen elephant trunk technique, deploying the J Graft FROZENIX into zone 1 or 2 (zone 1: n = 17, zone 2: n = 33) in combination with the Gelweave Lupiae graft for acute Stanford type A acute aortic dissection. Patient characteristics, intraoperative data, and early and midterm outcomes were analyzed. RESULTS The overall in-hospital mortality rate was 4% (2 patients). The in-hospital mortality rate in patients with visceral malperfusion was 11% (1/9). There were no patients with paraplegia and stent graft-induced new entry. Resection or closure of the most proximal entry tear was achieved in 100% of 42 patients who had postoperative computed tomography. The overall survival was 87.9%, 84.1%, and 84.1% at 1, 2, and 3 years, respectively. However, 1 patient required endovascular extension for the dilatation of the descending thoracic aorta 4 months after the initial surgery. CONCLUSIONS Total aortic arch replacement with the frozen elephant trunk technique (zone 1-2) and Gelweave Lupiae graft was safe and effective in simplifying surgery for acute Stanford type A acute aortic dissection.

Abstract
OBJECTIVE To report our own experience of hybrid treatment using FET technique in patients with type A aortic dissection and concomitant lesion of aortic arch and ascending aorta. MATERIAL AND METHODS There were 90 (28,3%) FET procedures for the period from January 2010 to August 2019. Type B aortic dissection was diagnosed in 19 (45,2%) patients. Type B aortic dissection combined with aortic arch aneurysm occurred in 11 (58%) cases, ascending aorta aneurysm - 15 (79%) cases. Patients underwent total arch and ascending aorta replacement via median sternotomy (upper partial J-shaped sternotomy in 3 cases). Valve-sparing interventions were performed in 58% of cases (aortic root repair - 6 (32%) patients, David procedure - 5 (26%) cases). Intraoperative features, early postoperative morbidity and in-hospital mortality were retrospectively analyzed. In long-term period, distal aortic remodeling, survival rate and incidence of redo interventions were evaluated. RESULTS Mean CPB time was 166±27 min, aortic cross-clamping time - 93±23 min, duration of circulatory arrest - 43±11 min. Neurological complications and paraplegia were absent. In-hospital mortality was absent. Reversible acute renal failure without need for hemodialysis developed in 2 cases (11%). Two patients underwent repeated intervention (TEVAR) due to dSINE and negative aortic remodeling. Annual survival rate was 100%. Freedom from redo aortic surgery was 89,5%. CONCLUSION FET surgery is an adequate alternative treatment for type B aortic dissection combined with lesion of aortic arch and ascending aorta. This approach ensures a one-stage repair in patients with contraindications to TEVAR. Unlike thoracotomy, FET procedure is valuable for simultaneous correction of cardiac and proximal aortic lesion, stabilizing the distal segments of dissected aorta. This is obvious advantage of this technique.

Abstract
OBJECTIVE This study aimed to evaluate the prevalence of spinal cord injury in total arch replacement with frozen elephant trunk for acute type A aortic dissection using our spinal cord protection technique. METHODS Between January 2013 and December 2017, 33 patients underwent total arch replacement with frozen elephant trunk for acute type A aortic dissection (mean age 67.9 ± 13.3 years). Our spinal cord protection technique involved maintaining extracorporeal circulation through the left subclavian artery in all procedures, using aortic occlusion balloon during distal anastomosis, and inserting frozen elephant trunk above Th 8 with transesophageal echocardiographic guidance. Computed tomography was performed within 1-2 weeks, 12 months, and 36 months postoperatively. We compared the degree of thrombosis of the descending aorta between preoperation and early postoperative period by Fisher's exact test. Moreover, we evaluated postoperative mortality and mobility (including spinal cord injury) at follow-up. RESULTS The operative mortality within 30 days was 6.1%. Neither paraplegia nor paraparesis was noted. We observed significant thrombosis of the false lumen at the distal arch and aortic valve level of the descending aorta in postoperative early term period (p < 0.01). At mid-term follow-up (mean 33.9 months), survival probability and 3-year freedom from reoperation rates were 93.9 ± 4.1% and 95.0 ± 4.9%, respectively. CONCLUSIONS The frozen elephant trunk technique with our spinal protection strategy provides good postoperative outcomes. Our strategy can maintain spinal cord perfusion without complete ischemia time even during lower body ischemia time. Implementation of our spinal protection strategy will help prevent spinal cord injury and dilated downstream aorta.

Abstract
Background The frozen elephant trunk (FET) technique is increasingly used for the treatment of acute and chronic aortic arch disease. This study reports our single center experience with the FET technique in patients with complex aortic disease. Methods Between 2009 and 2019, 111 consecutive patients underwent aortic arch surgery in our institution using the FET technique for acute type A dissection (AAD group; n=75) or non-acute type A dissection (non-AAD group; n=36; 10 patients with chronic type A dissection; 26 patients with aneurysm), respectively. Relevant perioperative data, including 30-day mortality and neurological complications, were retrospectively obtained from our electronic patient’s records, including follow-up (FU) data of outpatient clinical visits and computed tomography (CT). Results Thirty-day mortality in the entire FET cohort was 16.2% (AAD 18.7% vs. non-AAD 11.1%; n=0.414). Severe brain injury was the leading cause of death in AAD patients (12.0% vs. 0% non-AAD; P=0.030). Overall permanent stroke and spinal cord injury was 12.6% and 3.6%. Four patients in the AAD group developed paraplegia and permanent stroke rate was significantly higher in AAD compared to non-AAD patients (17.3% vs. 2.8%; P=0.034). One, 3- and 5-year survival rates were 78.7%±4.0%, 72.2%±4.8%, and 64.3%±6.8% for the total cohort; survival at 1-, 3- and 5-year was 76.7%±5.0%, 71.0%±6.1%, and 64.5%±8.3% for the AAD cohort compared to 83.1%±6.3%, 75.0%±7.9% and 66.7% for non-AAD patients (P=0.579), respectively. Conclusions Our single-center experience confirms good early and mid-term survival after the FET procedure in patients presenting with AAD, CAD and aneurysm. Future efforts should focus on reduction of severe neurological complication.

Abstract
Background Frozen elephant trunk (FET) enables treatment of arch and proximal descending thoracic aorta aneurysms. In treating patients with single-stage FET, the relationship of distal stent size to endoleak and reintervention has remained unexamined. Methods In this retrospective analysis of 63 cases in which FET was used to repair aneurysms between 2008 and 2019, 36 were intended as single-stage procedures. Effective sizing and sealing of distal stents were analyzed by preoperative and postoperative computed tomography angiography (CTA). Results During a mean of 25.8 ± 5.7 months of CTA follow-up, 10 of 36 (28%) experienced endoleak, and 3 of 36 (8%) had sac expansion. Ultimately, 5 of 13 (38%) underwent thoracic endovascular aneurysm repair. Patients without endoleak or sac expansion were more likely to have stents with >10% oversize and a >30-mm seal in healthy aorta compared with those experiencing these complications (11 of 23 vs 0 of 13; P = .0031). Conversely, 11 of 36 patients (31%) with adequately oversized and sealed stents developed fewer endoleaks compared with those without (0 of 11 vs 10 of 14; P < .0004). Patients with endoleak or sac expansion had smaller mean distal stent oversize and shorter mean sealing length compared with those without endoleak or sac expansion (2.3 ± 3.9% vs 18 ± 2.9% [P = .0023] and 1 ± 0.7 mm vs 34 ± 6 mm [P = .0005], respectively). Conclusions We recommend >10% distal stent oversize and >30-mm sealing length to minimize endoleak and reintervention. Increasing multidisciplinary collaboration with endovascular surgeons will improve distal stent planning.

Abstract
Background The frozen elephant trunk (FET) procedure remains an increasingly popular approach to address complex multi-segmental aortic pathologies, owing to their ability to promote false lumen thrombosis and reduce the need for second-stage operations. While the short-term outcomes of such procedures have been shown to be acceptable, much less is known regarding long-term outcomes. This systematic review evaluates long-term outcomes of the FET procedure. Methods Studies with at least 12 months follow-up data on FETs were identified in four electronic databases. All studies were reviewed by two independent researchers and relevant data extracted. Long-term outcomes, including overall survival, freedom from reintervention, and freedom from aortic events, were evaluated using patient data recreated from digitized Kaplan-Meier curves. Results Thirty-seven studies with 4,178 patients were identified. The majority of the studies focused solely on acute dissections. Average follow-up was 3.2 years. Overall survival at 1-, 3-, and 5-year was 89.6%, 85.2%, and 82.0%, respectively. Freedom from reintervention at the same timepoints were 93.9%, 89.3%, and 86.8%, respectively. Mortality, permanent neurological deficit and spinal cord injury were 10.2%, 7.7%, and 6.5%, respectively. Conclusions Survival after the FET procedure is favorable, though ongoing close serial monitoring is essential to assess for the need for further reintervention. Larger multi-institutional registries are required to provide more robust evidence to better elucidate the patient cohort that would most benefit from the FET.

Abstract
This article reviews endovascular management of chronic post-dissection aneurysms of the aortic arch. Therapeutic strategies intended for this complex aortic condition are evolving rapidly to allow the treatment of various hostile aortic anatomy and frail patients. Principles, technical considerations, devices and outcomes of each technique are reviewed and summarized. Hybrid repair offer similar early mortality and stroke rates compared to open conventional surgery. Arch chimney and other parallel graft techniques present poor long term outcome, and should be limited to emergency situations where no other option is available. Fenestrated stent-grafting is subjected to many technical challenges in aortic arch due to difficulties in stent-graft orientation and fenestration positioning. In situ fenestration is an off-label technique that should only be used as an emergency bailout maneuver, considering that temporary coverage of supra aortic trunk vessel and its long-term durability raise concern. Finally, in experienced hands and appropriate anatomic conditions, arch branched graft technology has shown itself to be a safe and effective alternative to open conventional surgery. No randomized controlled trials have yet compared total endovascular aortic arch repair with hybrid techniques and open arch repair. The management of chronic post-dissection aneurysms of the aortic arch is challenging, decision-making and interventions should continue to be performed in high-volume centers with a dedicated aortic team with an expertise in both open and endovascular repairs.

Abstract
Total aortic arch replacement (TAR) with frozen elephant trunk (FET) technique (FET) has been increasingly used to treat a variety of aortic pathologies over the past two decades. Because FET can effectively treat the diseased arch and cover the proximal entry tear in the distal arch, it is a valuable option in the treatment of DeBakey I aortic dissections. This report focuses on the techniques and outcomes of TAR with FET for acute/chronic aortic dissection. A review of pooled literature including 27 observational studies showed in-hospital mortality, permanent stroke, and spinal cord injury rates of 8.4%, 5.9% and 2.6% for acute aortic dissections, and 7.5%, 4.0% and 4.6% for chronic aortic dissections, respectively. In most of the studies, complete false lumen thrombosis rate was achieved in 80% of patients at the level of FET for acute and chronic aortic dissections. Mid-term outcomes are equally promising. For chronic aortic dissections, positive remodeling of the non-stented distal aortic segments is less frequent leading to secondary reinterventions within 3 to 5 years. However, most studies have not applied distal abdominal extensions of the repair using fenestrated and branched endografts. In the current endovascular era, TAR + FET should be considered as an alternative to conventional open surgical repair in centers of excellence.

Abstract
BACKGROUND The purpose of this study was to evaluate the risk factors for spinal cord injury (SCI) in patients with acute aortic dissection undergoing surgery with frozen elephant trunk technique (FET). METHODS From December 2014 to February 2018, 17 patients with acute aortic dissection underwent surgical treatment of the aortic arch with FET. SCI occurred in 3 patients. Risk factors for SCI were evaluated. RESULTS Mean age of the patients was 56 years and 88.2% were male. The ratio of true lumen to total aortic diameter at the level of carina (before: 0.48 vs. after: 0.75, P < 0.001), aortic valve (before: 0.47 vs. after: 0.67, P = 0.001), and celiac artery (before: 0.48 vs. after: 0.68, P = 0.003) increased after surgery. There were no significant differences in perioperative minimum hemoglobin level and postoperative mean arterial pressure between patients with and without SCI. However, patients with SCI had higher creatinine level before surgery (SCI: 1.32 mg/dL vs. no SCI: 0.81 mg/dL, P = 0.023). Although there was no difference in number of patent intercostal arteries before surgery, those originating from the true lumen were fewer in patients with SCI (SCI: 2.7 vs. no SCI: 8.6, P = 0.021). Furthermore, with entry closure, significant decrease in patency was observed in intercostal arteries originating from the false lumen (before: 3.1 vs. after: 1.0, P < 0.001). CONCLUSION FET was useful in entry closure. However, FET in patients with higher creatinine level and those who may have significant spinal cord perfusion from the false lumen could be a risk factor for postoperative SCI.

Abstract
PURPOSE Postoperative spinal cord injury is a devastating complication after aortic arch replacement. The purpose of this study was to determine the predictors of this complication. METHODS A group of 254 consecutive patients undergoing aortic arch replacement via median sternotomy, with (n = 78) or without (n = 176) extended replacement of the upper descending aorta, were included in a risk analysis. The frozen elephant trunk technique was used in 46 patients. The patients' atherothrombotic lesions (extensive intimal thickening of > 4 mm) were identified from computed tomography images. RESULTS Complete paraplegia (n = 7) and incomplete paraparesis (n = 4) occurred immediately after the operation (permanent spinal cord injury rate, 1.97%; transient spinal cord injury rate, 2.36%). A multivariable logistic regression analysis identified the use of the frozen elephant trunk technique (odds ratio 36.3), previous repair of thoracoabdominal aorta or descending aorta (odds ratio 29.4), proximal atherothrombotic aorta (odds ratio 9.6), chronic obstructive lung disease (odds ratio 7.1) and old age (odds ratio 1.1) as predictors of spinal cord injury (p < 0.0001, area under curve 0.93). CONCLUSIONS Spinal cord injury occurs with a non-negligible incidence following aortic arch replacement. The full objective assessment of the morphology of the whole aorta and the recognition of the risk factors are mandatory.

Abstract
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
Abstract
OBJECTIVES
The aim of this study was to evaluate early- and mid-term outcome and aortic remodelling in patients undergoing implantation of 2 different frozen elephant trunk prostheses, either the Thoraflex™ hybrid (Vascutek, Inchinnan, UK) and the E-vita Open (Jotec Inc., Hechingen, Germany) for acute aortic dissection.
METHODS
All consecutive patients [n = 88; median age 59 (49–67) years; 69% male] undergoing surgery with a frozen elephant trunk prosthesis for acute aortic dissection from August 2005 until March 2018 were included in this study. The Thoraflex™ device was implanted in 55 patients and the E-vita Open graft in 33 patients.
RESULTS
Preoperative characteristics did not differ significantly between groups. There was also no statistically significant difference in postoperative outcome: in-hospital mortality (11% vs 12%; P > 0.99), stroke (18% vs 6%; P = 0.12) and spinal cord injury (6% vs 6%; P > 0.99). While there was no statistically significant difference in the occurrence of distal stent graft-induced new entries (16% vs 18%; P = 0.77), there was a significantly higher rate of secondary endovascular aortic interventions in the Thoraflex™ hybrid group (22% vs 0%; P = 0.003). There was a trend towards a higher rate of false lumen thrombosis at the level of the stent graft (74% vs 95%; P = 0.085) and was comparable at the thoraco-abdominal transition (53% vs 80%; P = 0.36) 1 year after implantation of the prostheses.
CONCLUSIONS
In this comparison of 2 frozen elephant trunk prostheses, there is no evidence that different surgical techniques influence in-hospital outcome. At 1-year follow-up, patients who underwent implantation of the E-vita Open prosthesis showed a significantly reduced rate of secondary aortic interventions and a trend towards a higher rate of false lumen thrombosis which might be attributed to a longer coverage of the descending aorta due to a longer stent graft design and significantly more frequent implantation in zone 3.
