[PMID: 38750942 DOI: 10.1016/j.jvs.2024.04.074] [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: 02/02/2024] [Revised: 03/25/2024] [Accepted: 04/23/2024] [Indexed: 06/11/2024]
Abstract
OBJECTIVE Prevention of late type Ia endoleaks is the main concern in thoracic endovascular aortic aneurysm repair (TEVAR) for thoracic aortic aneurysm. Since 2017, we have performed zone 0 TEVAR with proximal fixation augmentation using a Najuta thoracic fenestrated stent graft in addition to zone 2 TEVAR for distal arch aneurysms. We report the early and midterm outcomes of TEVAR performed using this strategy. METHODS This single-center retrospective study enrolled 386 cases of TEVAR for thoracic aortic disease between January 2013 and December 2020. Patients with thoracic aortic aneurysm treated by TEVAR landing at zone 2 was referred to as the standard group, whereas those treated by TEVAR landing at zone 0 using a Najuta fenestrated stent graft in addition to zone 2 TEVAR was referred to as the augmentation group. We retrospectively compared the clinical outcomes between the two groups. The primary end point was secondary intervention for postoperative type Ia endoleaks. Secondary end points were technical success, aneurysm-related death, and major adverse events (MAEs), including stroke, paraplegia, endoleaks, and secondary interventions. RESULTS We performed TEVAR in 41 and 30 cases in the standard and augmentation groups, respectively. The mean aneurysm sizes in the standard and augmentation groups were 54.5 and 57.3 mm (P = .23), and the proximal neck lengths were 16.8 and 17.4 mm (P = .65), respectively. The anatomical characteristics seemed to be similar in both groups. The technical success rate in both groups was 100%. Three cases in the standard group had MAEs, including two stroke and one brachial artery pseudoaneurysm; whereas two cases had MAEs in the augmentation group, including one stroke and one paraplegia. There was no 30-day mortality or retrograde type A dissection in both groups. The mean observation periods in the standard and augmentation groups were 46 months (range, 1-123 months) and 35 months (range, 1-73 months), respectively. At 36 and 60 months after the procedure, the freedom from aneurysm-related death was 97.6% and 97.6% in the standard group, 100.0% and 100.0% in the augmentation group (P = .39); and the freedom from reintervention for type Ia endoleaks was 79.2% and 65.2% in the standard group, 100.0% and 100.0% in the augmentation group (P = .0087). A statistically significant decrease in reinterventions for type Ia endoleaks was observed in the augmentation group. CONCLUSIONS Proximal fixation augmentation using the Najuta fenestrated stent graft during TEVAR for distal arch aneurysm is effective in preventing the postoperative late type Ia endoleaks.

A meta-analysis on the effect of proximal landing zone location on stroke and mortality in thoracic endovascular aortic repair. J Vasc Surg 2023; 78:1559-1566.e5. [PMID: 37201762 DOI: 10.1016/j.jvs.2023.05.014] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 04/19/2023] [Accepted: 05/10/2023] [Indexed: 05/20/2023]
Abstract
BACKGROUND Thoracic endovascular aortic repair (TEVAR) involving the aortic arch may increase the opportunity for stroke owing to disruption of cerebral circulation and embolization. In this study, a systematic meta-analysis was performed to examine the impact of proximal landing zone location on stroke and 30-day mortality after TEVAR. METHODS MEDLINE and Cochrane Library were searched for all original studies of TEVAR reporting outcomes of stroke or 30-day mortality for at least two adjacent proximal landing zones, based on the Ishimaru classification scheme. Forest plots were created using relative risks (RR) with 95% confidence intervals (CI). An I2 of <40% was regarded as minimal heterogeneity. A P value of <.05 was considered significant. RESULTS Of the 57 studies examined, a total of 22,244 patients (male 73.1%, aged 71.9 ± 11.5 years) were included in the meta-analysis, with 1693 undergoing TEVAR with proximal landing zone 0, 1931 with zone 1, 5839 with zone 2, and 3089 with zone 3 and beyond. The overall risk of clinically evident stroke was 2.7% for zones ≥3, 6.6% for zone 2, 7.7% for zone 1, and 14.2% for zone 0. More proximal landing zones were associated with higher risks of stroke compared with distal (zone 2 vs ≥3: RR, 2.14; 95% CI, 1.43-3.20; P = .0002; I2 = 56%; zone 1 vs 2: RR, 1.48; 95% CI, 1.20-1.82; P = .0002; I2 = 0%; zone 0 vs 1: RR, 1.85; 95% CI, 1.52-2.24; P < .00001; I2 = 0%). Mortality at 30 days was 2.9% for zones ≥3, 2.4% for zone 2, 3.7% for zone 1, and 9.3% for zone 0. Zone 0 was associated with higher mortality compared with zone 1 (RR, 2.30; 95% CI, 1.75-3.03; P < .00001; I2 = 0%). No significant differences were found in 30-day mortality between zones 1 and 2 (P = .13) and between zone 2 and zones ≥3 (P = .87). CONCLUSIONS The risk of stroke from TEVAR is lowest in zone 3 and beyond, increasing significantly as the landing zone is moved proximally. Furthermore, perioperative mortality is increased with zone 0 compared with zone 1. Therefore, risk of stent grafting in the proximal arch should be weighed against alternative surgical or nonoperative options. It is anticipated that the risk of stroke will improve with further development of stent graft technology and implantation technique.

Abstract
PURPOSE The purpose of this study was to evaluate the efficacy and safety of zone 2 thoracic endovascular aortic repair assisted by the chimney technique or single-branched stent graft for the preservation of the left subclavian artery, and summarize our single-center experience with the techniques. MATERIALS AND METHODS From February 2017 to June 2020, 137 patients who underwent left subclavian artery revascularization during zone 2 thoracic endovascular aortic repair were enrolled. Patients had acute type B aortic dissection and penetrating aortic ulcer associated with intramural hematoma. The chimney technique was performed in 68 patients (group A), and single-branched stent graft was deployed in 69 patients (group B). All procedures were performed during the acute phase. Primary technical success, immediate postoperative endoleak, neurologic complications (stroke or spinal cord ischemia), 30-day mortality, 1-year technical success, all-cause mortality, patency of the left subclavian artery, and reintervention were analyzed. Comparing the occurrence of the Bird-Beak Configuration, defined as a gap between the aortic wall and the sent graft with stent protrusion into the aortic lumen more than 5 mm, was also performed. RESULTS Primary technique success was achieved in 66 and 67 patients in groups A and B, respectively. The incidence of immediate postoperative endoleak, neurologic complications (stroke or spinal cord ischemia), and 30-day mortality were 5.9%, 1.5%, and 4.4% in group A, and 2.9%, 2.9%, and 2.9% in group B, respectively. During follow-up, the 1-year technical success rate was similar in both groups. All-cause mortality was similar in both groups (3.1% in group A and 4.5% in group B). The patency of the left subclavian artery was not significantly different between the 2 groups with 2 and 3 occlusions in groups A and B, respectively. The rate of reintervention was higher in group B (3.1% vs 1.6%, p=0.536), with a non-significant difference. Bird-Beak Configuration was more prominent in group B with the incidence of 59.42%. CONCLUSIONS Acting as minimally invasive alternatives, both techniques are feasible for left subclavian artery preservation during zone 2 thoracic endovascular aortic repair for type B acute aortic syndromes with encouraging mid-term outcomes. Long-term follow-up is required to confirm these findings.

Abstract
PURPOSE Displacement forces (DFs) identify hostile landing zones for stent graft deployment in thoracic endovascular aortic repair (TEVAR). However, their use in TEVAR planning is hampered by the need for time-expensive computational fluid dynamics (CFD). We propose a novel fast-approximate computation of DFs merely exploiting aortic arch anatomy, as derived from the computed tomography (CT) and a measure of central aortic pressure. MATERIALS AND METHODS We tested the fast-approximate approach against CFD gold-standard in 34 subjects with the "bovine" aortic arch variant. For each dataset, a 3-dimensional (3D) model of the aortic arch lumen was reconstructed from computed tomography angiography and CFD then employed to compute DFs within the aortic proximal landing zones. To quantify fast-approximate DFs, the wall shear stress contribution to the DF was neglected and blood pressure space-distribution was averaged on the entire aortic wall to reliably approximate the patient-specific central blood pressure. Also, DF values were normalized on the corresponding proximal landing zone area to obtain the equivalent surface traction (EST). RESULTS Fast-approximate approach consistently reflected (r2=0.99, p<0.0001) the DF pattern obtained by CFD, with a -1.1% and 0.7° bias in DFs magnitude and orientation, respectively. The normalized EST progressively increased (p<0.0001) from zone 0 to zone 3 regardless of the type of arch, with proximal landing zone 3 showing significantly greater forces than zone 2 (p<0.0001). Upon DF normalization to the corresponding aortic surface, fast-approximate EST was decoupled in blood pressure and a dimensionless shape vector (S) reflecting aortic arch morphology. S showed a zone-specific pattern of orientation and proved a valid biomechanical blueprint of DF impact on the thoracic aortic wall. CONCLUSION Requiring only a few seconds and quantifying clinically relevant biomechanical parameters of proximal landing zones for arch TEVAR, our method suits the real preoperative decision-making process. It paves the way toward analyzing large population of patients and hence to define threshold values for a future patient-specific preoperative TEVAR planning.

Abstract
BACKGROUND Retrograde type A dissection (RTAD) is a devastating complication of thoracic endovascular repair (TEVAR) with low incidence but high mortality. The objective of this study is to report the incidence, mortality, potential risk factors, clinical manifestation and diagnostic modalities, and medical and surgical treatments. METHODS A systematic review and single-arm and two-arm meta-analyses evaluated all published reports of RTAD post-TEVAR through January 2021. All study types were included, except study protocols and animal studies, without time restrictions. Outcomes of interest were procedural data (implanted stent-grafts type, and proximal stent-graft oversizing), the incidence of RTAD, associated mortality rate, clinical manifestations, diagnostic workouts and therapeutic management. RESULTS RTAD occurred in 285 out of 10,600 patients: an estimated RTAD incidence of 2.3% (95% CI: 1.9-2.8); incidence of early RTAD was approximately 1.8 times higher than late. Wilcoxon signed-rank testing showed that the proportion of RTAD patients with acute type B aortic dissection (TBAD) was significantly higher than those with chronic TBAD (P = .008). Pooled meta-analysis showed that the incidence of RTAD with proximal bare stent TEVAR was 2.1-fold higher than with non-bare stents: risk ratio was 1.55 (95% CI: 0.87-2.75; P = .13). Single arm meta-analysis estimated a mortality rate of 42.2% (95% CI: 32.5-51.8), with an I2 heterogeneity of 70.11% (P < .001). CONCLUSION RTAD is rare after TEVAR but with high mortality, especially in the first month post-TEVAR with acute TBAD patients at greater risk as well as those treated with proximal bare stent endografts.

Abstract
Background: The total endovascular repair of the aortic arch is becoming more and more an acceptable alternative to the open repair in selected patients. The aim of the present study is to perform a meta-analysis of the available data on the outcomes of the various endovascular techniques used to treat the pathologies in this challenging anatomical area. Patients and methods: An extensive electronic search in PubMed/MEDLINE, Science Direct Databases, and the Cochrane Library was conducted. All papers published up to January 2022 on the endovascular techniques in the aortic arch (chimney-thoracic endovascular aortic repair (ChTEVAR), fenestrated/branched grafts as custom made devices (CMD) and surgeon modified TEVAR (SM TEVAR) providing information about at least one of the essential outcomes defined in the inclusion criteria. Results: Out of the 5078 studies found through the search in the databases and registers, 26 studies with a total number of patients of 2327 with 3497 target vessels were included in the analysis. The studies reported a high technical success rate with an estimated proportion of 95.8% (95% CI, 93-97.6%). Moreover, the pooled estimation of the early type Ia/III endoleak was 8.1% (95% CI, 5.4-12.1%). The pooled mortality was 4.6% (95 CI, 3.2-6.6%) with a significant heterogeneity and the stroke had an estimated proportion (major and minor combined) of 4.8% (95% CI, 3.5-6.6%). A meta-regression analysis showed no significant variation between the groups in mortality (P=.324) showed however a significant difference between the therapeutic methods regarding stroke P<.001 (lower rate in ChTEVAR and SM vs. CMD). Conclusions: The present meta-analysis could demonstrate good short- and long-term outcomes of the multiple total endovascular repair methods used in the aortic arch.

Abstract
Background Thoracic endovascular aortic repair, initially intended for thoracic aortic disease treatment, has extended its application to the proximal zone of the aorta. However, the safety and surgical outcomes of extending the proximal landing zone into the ascending aorta (zone 0) in selected cases remain unknown. Thus, we performed a systematic review and meta-analysis of zone 0 thoracic endovascular aortic repair (TEVAR) to obtain a deeper understanding of its safety, outcomes, and trends over time. Methods A literature search was performed using PubMed, EMBASE, and Web of Science databases in accordance with the preferred reporting items for systematic reviews and meta-analyses guidelines, from January, 1997 to January, 2022. Only studies involving zone 0 TEVAR were included. The retrieved data from the eligible studies included basic study characteristics, 30-day/in-hospital mortality rate, indications, comorbidities, stent grafts, techniques, and complications. Summary effect measures of the primary outcomes were obtained by logarithmically pooling the data with an inverse variance-weighted fixed-effects model. Results Fifty-three studies with 1,013 patients were eligible for analysis. The pooled 30-day/in-hospital mortality rate of zone 0 TEVAR was 7.49%. The rates of post-operative stroke, type Ia endoleak, retrograde type A aortic dissection, and spinal cord ischemia were 8.95, 9.01, 5.72, and 4.12%, respectively. Conclusions Although many novel stent grafts and techniques targeting zone 0 TEVAR are being investigated, a consensus on technique and device selection in zone 0 TEVAR is yet to be established in current practice. Furthermore, the post-operative stroke rate is relatively high, while other complication rates and perioperative death rate are comparable to those of TEVAR for other aortic zones.

Abstract
BACKGROUND In the last decade, new stent graft designs have evolved to tackle challenges in thoracic endovascular aortic repair. A specific focus on access vessel issues has led to the introduction of new low-profile endograft designs for most of the major products. OBJECTIVE The main objective of this article is to provide an overview of the available publications on new stent graft designs. MATERIALS AND METHODS Assessing recent publications on the major reiterations of thoracic endografts, benefits and drawbacks are discussed. RESULTS Recent reiterations of major endografts for thoracic aortic endovascular repair have focused mainly on the development of low-profile devices. Through alterations on graft fabric as well as stent material and design, delivery systems were reduced in profile, thus, reducing access vessel complications or enabling an endovascular procedure altogether. Long-term data are already available for one endoprosthesis. Other refinements include in situ adaptation of the stent graft to the aortic arch curvature as well as the option of staged deployment to allow more precision and reduce manipulation close to supra-aortic branches. CONCLUSIONS Especially in the case of low-profile endografts, preliminary and long-term results of access vessel complications are promising. In order to draw final conclusions as to how durable the results of aneurysm exclusion are, more long-term studies are warranted.

Abstract
Endovascular repair of the descending thoracic aorta has gained widespread acceptance as a primary treatment modality for thoracic aortic disease due to its minimally invasive approach and improved survival rates. GORE® TAG® Conformable Thoracic Stent Graft was designed for descending thoracic aortic aneurysms, penetrating ulcers, aortic transections and type B aortic dissections, which are accepted indications for endovascular therapy. The aim of this review is to summarize the clinical literature, focusing mainly on the publications that came from manufacturer's pre-market and post-market studies. Including the Global Registry for Endovascular Aortic Treatment (GREAT), sponsored by WL Gore & Associates (Flagstaff, AZ, USA), which is a large database of endovascular repair of various thoracic, abdominal and thoraco-abdominal aortic pathologies to identify and evaluate only those with isolated thoracic aortic pathology (arch and descending thoracic).

Abstract
Objective: The aim of this study was to report 10-year real-world single-center experience with the GORE TAG conformable thoracic aortic graft (CTAG), focusing on rupture-free survival, aortic-related reintervention, and device-related complications during midterm and long-term follow-up (FU). Methods: This retrospective study analyzes results of thoracic endovascular aortic repair (TEVAR) performed between January 2009 and December 2018. Out of 419 TEVAR procedures within this period, 194 patients (male 57.2%, 111/194), with a mean age of 65 ± 13 years, were treated with the CTAG device. Indication for TEVAR was a thoracic aortic aneurysm in 24.7% (48/194), type B aortic dissection in 32.5% (63/194), penetrating aortic ulcer 15.5% (30/194), and miscellaneous 27.3% (53/194). Emergently were operated 43.8% (85/194) patients. Median follow-up (FU) including computed tomography imaging was 43.5 months (Q1-Q3: 8.6–67.0) and was completed in 91.2% (177/194) of patients. Results: Overall survival rates were 75.8% (95% confidence interval [CI] = [0.76–0.70]) and 56.6% (95% CI = [0.57–0.50]) at 12 and 60 months, respectively. Cumulative incidence for aortic rupture was 11.9% (95% CI = [0.07–0.17]) at 60 and 90 months, respectively. Cumulative incidence for aortic-related reintervention was 27.5% (95% CI = [0.21–0.34]) at 60 and 90 months. Cumulative incidence for migration was 2.8% (95% CI = [0.004–0.05]) and 3.9% (95% CI = [0.007–0.07]) at 60 and 90 months, respectively. New endograft infections or material fatigue were not observed. Conclusions: The herein reported 10-year real-world single-center experience with the CTAG observed favorable long-term outcome. Thus, the device demonstrates appropriate persistent safety, efficacy, and clinical durability up to long-term FU in the treatment of diverse thoracic aortic pathologies.

Abstract
OBJECTIVES The aim of this study was to evaluate technical/clinical outcomes of the Gore TAG Conformable Thoracic Stent Graft with Active Control System (CTAG with ACS) in thoracic aortic disease since its introduction in Europe in 2017. METHODS Patients undergoing thoracic endovascular aortic repair (TEVAR) with the device between 2017 and 2020 were identified from a prospectively maintained single-centre database and retrospectively analysed. Predominant indications were aortic dissection (n = 46), thoracic/thoraco-abdominal aneurysm (n = 20/n = 7), penetrating ulcer (n = 14) and intramural haematoma (n = 12). Emergency procedures were performed in 47% (54/115). The primary outcome was technical success. Secondary outcomes were clinical success, serious adverse events and procedure-related reintervention. ACS was assessed regarding angulation, accuracy and apposition. The median follow-up was 8.46 months (interquartile range: 3.18-16.89 months). RESULTS A total of 115 consecutive patients (82 males, median age 63; interquartile range: 53-74 years) have been included. Technical success was achieved in 95.7% (110/115). Clinical success rate was 80.9% (93/115); mostly due to procedure-related death (n = 14). Overall mortality was 19.1% (22/115), with significant differences between elective/emergency procedures (log-rank: P < 0.001). Procedure-related serious adverse event rate was 44.3% (51/115). Procedure-related reintervention was performed in 20.9% (24/115). The cumulative incidence for reintervention differed significantly between elective/emergency cases (Gray's test: P = 0.0033). Angulation was used in 40.9% of patients (47/115), mostly in type II arches (52.7%). Deployment accuracy was 87.8% (101/115). Sufficient apposition was present in 93.0% (107/115). CONCLUSIONS This single-centre study shows encouraging performance of the CTAG with ACS in an array of aortic pathologies. Although longer-term data must be awaited, ACS leads to overall favourable device placement. Despite ongoing advances in device technology, TEVAR remains challenging and is associated with significant burden inherent to the underlying disease.

Abstract
BACKGROUND Thoracic aortic arch aneurysms (TAAs) can be a life-threatening condition due to the potential risk of rupture. Treatment is recommended when the risk of rupture is greater than the risk of surgical complications. Depending on the cause, size and growth rate of the TAA, treatment may vary from close observation to emergency surgery. Aneurysms of the thoracic aorta can be managed by a number of surgical techniques. Open surgical repair (OSR) of aneurysms involves either partial or total replacement of the aorta, which is dependent on the extent of the diseased segment of the aorta. During OSR, the aneurysm is replaced with a synthetic graft. Hybrid repair (HR) involves a combination of open surgery with endovascular aortic stent graft placement. Hybrid repair requires varying degrees of invasiveness, depending on the number of supra-aortic branches that require debranching. The hybrid technique that combines supra-aortic vascular debranching with stent grafting of the aortic arch has been introduced as a therapeutic alternative. However, the short- and long-term outcomes of HR remain unclear, due to technical difficulties and complications as a result of the angulation of the aortic arch as well as handling of the arch during surgery. OBJECTIVES To assess the effectiveness and safety of HR versus conventional OSR for the treatment of TAAs. SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL and AMED databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 22 March 2021. We also searched references of relevant articles retrieved from the electronic search for additional citations. SELECTION CRITERIA We considered for inclusion in the review all published and unpublished randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing HR to OSR for TAAs. DATA COLLECTION AND ANALYSIS Two review authors independently screened all titles and abstracts obtained from the literature search to identify those that met the inclusion criteria. We retrieved the full text of studies deemed as potentially relevant by at least one review author. The same review authors screened the full-text articles independently for inclusion or exclusion. MAIN RESULTS No RCTs or CCTs met the inclusion criteria for this review. AUTHORS' CONCLUSIONS Due to the lack of RCTs or CCTs, we were unable to determine the safety and effectiveness of HR compared to OSR in people with TAAs, and we are unable to provide high-certainty evidence on the optimal surgical intervention for this cohort of patients. High-quality RCTs or CCTs are necessary, addressing the objective of this review.

Abstract
BACKGROUND The Gore conformable TAG thoracic endoprosthesis (CTAG) was engineered to enhance conformability in the thoracic aorta and has demonstrated greater deployment accuracy and wall apposition than the original TAG device. The Food and Drug Administration approved the CTAG in 2011 based on the 1-year results of the pivotal trial for the CTAG device. In the present report, we have documented the outcomes for those patients through 5 years. METHODS The CTAG aneurysm study was a prospective, multicenter trial that assessed the safety and effectiveness of the CTAG device as treatment of descending thoracic aortic aneurysms. Follow-up imaging assessments consisted of radiographs and computed tomography at annual intervals through 5 years. A core imaging laboratory was used to assess the aneurysm size, device integrity, and endoleaks. RESULTS A total of 66 patients were enrolled (51 pivotal arm patients and 15 continued access patients) from October 2009 through September 2011. The baseline characteristics, procedural characteristics, and outcomes through 2 years were reported previously. Through 5 years, five patients (7.6%) had required device-related reintervention (one type Ia endoleak or contained rupture of the descending thoracic aorta, one type Ib endoleak, two indeterminate endoleaks, and one thoracic aortic pseudoaneurysm). Four patients (6.1%) had died of aneurysm-related causes, with one death occurring within 30 days of the index procedure. A total of 24 patients (36.3%) had died during the 5-year study period. Seven patients (10.6%) had experienced stroke or transient ischemic attack through 5 years, with one early stroke (postoperative day 28). Prosthesis or intercomponent migration was observed in six patients (9.1%) through 5 years; however, no patient had developed a type III junctional endoleak. No stent-graft fracture or compression was observed through 5 years. At 5 years, 14 patients (50.0%) showed sac regression, 5 (17.9%) showed sac expansion, and 9 (32.1%) showed sac stability using on a 5-mm threshold for change. CONCLUSIONS Thoracic endovascular aortic repair with the CTAG device was associated with low rates of aneurysm-related mortality and reintervention through 5 years. Proximal endoleak was rare, and most patients showed sac regression or stability at 5 years after the initial thoracic endovascular aortic repair.

Abstract
PURPOSE Up to 10% of acute type A aortic dissection (TAAD) patients are deemed unfit for open surgical repair, exposing these patients to high mortality rates. In recent years, thoracic endovascular aortic repair has proven to be a promising alternative treatment modality in specific cases. This study presents a comprehensive overview of the current state of catheter-based interventions in the setting of primary TAAD. METHODS A literature search was conducted, using MEDLINE and PubMed databases according to PRISMA guidelines, updated until January 2020. Articles were selected if they reported on the endovascular repair of DeBakey Type I and II aortic dissections. The exclusion criteria were retrograde type A dissection, hybrid procedures, and combined outcome reporting of mixed aortic pathologies (e.g., pseudoaneurysm and intramural hematoma). RESULTS A total of 31 articles, out of which 19 were case reports and 12 case series, describing a total of 92 patients, were included. The median follow-up was 6 months for case reports and the average follow-up was 14 months for case series. Overall technical success was 95.6% and 30-day mortality of 9%. Stroke and early endoleak rates were 6% and 18%, respectively. Reintervention was required in 14 patients (15%). CONCLUSION This review not only demonstrates that endovascular repair in the setting of isolated TAAD is feasible with acceptable outcomes at short-term follow-up, but also underlines a lack of mid-late outcomes and reporting consistency. Studies with longer follow-up and careful consideration of patient selection are required before endovascular interventions can be widely introduced.

Abstract
PURPOSE To assess outcomes of a low-profile thoracic stent-graft in the treatment of thoracic aortic pathologies. METHODS A retrospective analysis of all consecutive patients with aortic thoracic pathologies treated with the RelayPro device in two university hospitals between October 2018 and July 2019. RESULTS 23 patients (65% men; mean age 63.4 ± 15 years) were treated. Pathologies included aortic dissections (n = 10), 5 residual type A (22%) and 5 type B (22%), 6 degenerative aortic aneurysms (26%), 4 penetrating aortic ulcers (17%), and aortic erosion, intramural hematoma and aortic rupture (n = 1 and 4% in each case). Two cases (9%) were emergent and two urgent. Proximal landing was achieved in zones 0 (4%), 1 (4%), 2 (43%), and 3 (26%). Five grafts were frozen elephant trunk extensions. Technical success was 100% with accurate device deployment in the intended landing zone of the aortic arch in all 23 patients and with no Ia/III endoleaks and three (13%) type II endoleaks. Apposition was adequate in 96%. Two patients had post-implantation syndromes (one fever, one leukocytosis). Mean follow-up was 11.6 ± 3.7 months (range, 2-16) with no other complications, secondary interventions or conversions to open surgery. There was no 30-day mortality and no aortic-related mortality; all-cause mortality was 4% during follow-up. CONCLUSION A 3-4 French reduced profile in the current generation of stent-grafts facilitates TEVAR particularly in patients with smaller vessels access. Early safety and effectiveness outcomes are favorable, even in endpoints such as deployment accuracy and apposition which may be surrogates for longer-term clinical success and durability.

Abstract
OBJECTIVE To describe the outcome of thoracic endovascular aortic repair (TEVAR) in thoracic aortic aneurysm and penetrating aortic ulcer with respect to instructions for use status. METHODS Between October 2009 and September 2017, a total of 532 patients underwent TEVAR; of which 195 have been treated using the Conformable GORE® TAG® thoracic endoprosthesis (CTAG). Fifty-six patients of this cohort underwent TEVAR for thoracic aortic aneurysm/penetrating aortic ulcer using the CTAG. Depending on the preoperative computed tomography angiography findings, patients were classified as inside or outside the device's instructions for use. All inside instruction for use patients underwent postoperative reclassification regarding the instructions for use status. Study endpoints included TEVAR-related reintervention, exclusion of the pathology (endoleak type I/III), TEVAR-related mortality, and graft-related serious adverse events. The median duration of follow-up was 29.7 months (range: 0-109.4 months). RESULTS Of the 56 patients, 17 were primarily classified as outside instruction for use, and in additional 13 patients, TEVAR was performed outside instruction for use, leading to 30 outside instruction for use patients (53.6%). Twenty-six patients (46.4%) were treated inside instruction for use. Reintervention-free survival was lower in outside instruction for use patients (P = 0.016) with a hazard ratio of 9.74 (confidence interval 1.2-80.2; P = 0.034) for TEVAR-related reintervention. With respect to endoleak type I/III, relevant difference was detected between inside/outside instruction for use status (P = 0.012). The serious adverse event rate was 30.4%, mainly in outside instruction for use patients (P = 0.004). Logistic regression analysis indicated an association between graft-related serious adverse event/instructions for use status (odds ratio 6.11; confidence interval 1.6-30.06; P = 0.012). In-hospital death was seen more frequently in outside instruction for use patients (P = 0.12) as was procedure-related death (log-rank test: P = 0.21). CONCLUSION TEVAR for thoracic aortic aneurysm/penetrating aortic ulcer is frequently performed outside instruction for use despite preoperative inside instruction for use eligibility, leading to important consequences for technical/clinical outcome. Instructions for use adherence in TEVAR should be of interest for further large-scale studies.

Abstract
BACKGROUND This study reports the early- and long-term outcomes of the thoracic endovascular aortic repair using the Chimney-Graft technique (ChTEVAR) for the treatment of aortic arch pathologies. METHODS From January 2010 to December 2019, patients who underwent aortic ChTEVAR technique in our institution were included. Early, mid, and long-term outcomes in this group of patients were evaluated. Patient follow-up data were obtained by imaging follow-up that are routinely performed after 3-6 months following initial surgery and then at yearly intervals. RESULTS Aortic arch repair with a ChTEVAR was performed in 54 patients. The 30-day mortality was 18.5% (n = 10). All-cause 30-day mortality was higher in the subgroup of patients operated urgently (33% vs. 14%) without a significant difference (P = 0.141). Permanent neurological deficit (PND) was observed in 15% (8/54 patients); stroke in 11% (6/54), and paraplegia 4% (2/54). During follow-up the primary and primary-assisted chimney-graft patency was 96.8% and 97.8%, respectively. The multivariate analysis identified the age >70 years and the aortic diameter as independent risk factors for elevated mortality during the follow-up (P = 0.015 and 0.001, respectively). The PND was an independent predictor for 30-day mortality (P = 0.014, hazard ratio 13.5, 95% confidence interval 1.7-106.6). CONCLUSIONS The ChTEVAR has noninferior results to other open and endovascular aortic arch repair methods with an acceptable long-term survival especially in elective procedures.

Abstract
Abstract
OBJECTIVES
Our goal was to assess the value of the Modified Arch Landing Areas Nomenclature (MALAN) for thoracic endovascular aortic repair (TEVAR), in which each landing area (LA) is identified by a proximal landing zone and the type of arch (e.g. 0/I), as predictors of postoperative proximal endograft performance.
METHODS
A multicentre retrospective analysis was performed of patients treated with arch TEVAR (i.e. proximal landing zone 0–3) for various indications between 2007 and 2017. Patients were stratified by the MALAN classification into hostile LAs (i.e. 2/III and 3/III) and favourable LAs (i.e. 0/I–III, 1/I–III, 2/I–II and 3/I–II). Outcome criteria included composite proximal endograft failure (including type Ia endoleak, persistent false lumen perfusion at the level of the most proximal communication between the lumina in aortic dissections, endograft migration and retrograde dissection) and deaths from all causes. Competing risk analyses were performed.
RESULTS
A total of 359 patients (hostile LAs 133; favourable LAs 226) were identified. The median age was 71.0 (62.0–77.0); 78.3% were men. Proximal endograft failure occurred in 28/133 patients (21.1%) in the hostile LA group and in 12/226 (5.3%) in the favourable LA group. On multivariate analysis, hostile LAs were independently associated with proximal endograft failure (P < 0.0001). There was no other independent risk factor. Favourable LAs were associated with an increased mortality rate (P = 0.006), which could be attributed to the proximal LA subgroup (i.e. 0/I–III and 1/I–III) (P < 0.0001), in addition to age (P < 0.0001).
CONCLUSIONS
The MALAN classification identifies hostile proximal landing zones for TEVAR, namely 2/III and 3/III LAs, which are associated with dismal proximal endograft performance. The MALAN appears to be an intuitive and valuable tool to improve the preoperative decision-making process.

Abstract
Penetrating aortic ulceration (PAU) is part of the spectrum of acute aortic syndromes (AAS), and is defined as an ulcerated intimal disruption due to atherosclerotic disease. PAU may be simple, isolated and asymptomatic, or it may be symptomatic, aneurysmal and extensive; these may progress and lead to rupture. This review aims to evaluate the treatment options for PAU. Treatment options range from radiological surveillance, risk factor modification, best medical therapy and open or endovascular surgical repair. Patients with PAU are frequently older and comorbid with relatively damaged aortic tissue; this can make open surgical repair more challenging. Endovascular repairs for larger, symptomatic, aneurysmal PAU may be performed with acceptable outcomes. Complex endovascular repairs may be required depending on the pathology. Patients with small, asymptomatic, uncomplicated PAU may be safely followed up with surveillance. PAU with concomitant intramural haematoma (IMH) should be closely monitored to observe for resolution or progression following conservative and medical management strategies. PAU is a unique entity and its natural history should be studied independently to better understand appropriate management strategies. This research is currently lacking, and larger studies or registries may be helpful in optimising PAU management.

Abstract
Background: Endovascular aortic aneurysm repair (EVAR) with stent-grafts is used widely for the treatment of thoracic aortic aneurysms (TAA). Inappropriate design of stent-grafts may lead to complications such as endoleak, stent-graft migration and new entries, causes of which may be inappropriate radial support force or insufficient longitudinal flexibility of the stent-grafts.Material and methods: To improve the mechanical performance of the stent-grafts, a type of non-equal-strut stent hoops was proposed, and the influence of structural parameters on the mechanical performance was studied.Results: Results of numerical simulation and physical experiments show that by using the proposed non-equal-strut stent hoops, radial support force and longitudinal flexibility of stent-grafts can be reconciled and balanced.Conclusion: Results of this study could be used to facilitate radial force control and longitudinal flexibility enhancement in the design of aortic stent-grafts.

Abstract
Purpose: To report the outcomes from the observational SURPASS
registry, which was created to assess the performance of the Conformable TAG
(CTAG) stent-graft with the Active Control System (ACS) in patients undergoing
thoracic endovascular aortic repair (TEVAR) in a real-world setting.
Materials and Methods: The SURPASS registry
(ClinicalTrials.gov; identifier NCT03286400) was an
observational, prospective, single-arm, post-market, international study that
enrolled patients undergoing TEVAR using the CTAG with ACS for both acute and
chronic thoracic aortic disease between October 2017 and July 2018. The CTAG
with ACS features 2-stage deployment of the stent-graft and an optional
angulation mechanism that modifies only the proximal end of the stent-graft.
During the observation period, 127 patients (mean age 67.1±12.1 years, range
27–86; 92 men) were enrolled and treated for an array of aortic pathologies,
including chronic and acute lesions and 4 ruptured descending thoracic
aneurysms. The primary outcome of this study was technical success; secondary
outcomes were clinical success and major adverse events at 30 days and 12
months. The numbers of 2-stage device deployments and applications of the
angulation mechanism were recorded, along with the reasons for use.
Results: Technical success of the TEVAR was 97.6% owing to
unintentional partial coverage of supra-aortic branches in 3 cases (the vessels
were patent on imaging). The stent-graft was repositioned at its intermediate
diameter in 79 patients (62.2%), and the angulation feature was applied in 64
cases (50.4%), mainly to improve proximal wall apposition and orthogonality in
the aorta. The desired effect was achieved in 60 cases (93.8%). There was no
device compression, bird-beak configuration, fracture, or graft occlusion. The
30-day and 12-month clinical success rates were 97.6% and 92.9%, respectively.
There were 3 aorta-related deaths at 30 days and a further 3 at 12 months.
Fatalities were due to a retrograde type A dissection (0.8%), paraplegia, bowel
ischemia, sepsis in the setting of a mycotic aneurysm, aneurysm rupture post
aortoesophageal fistula, and multiorgan dysfunction syndrome. Three endoleaks (2
type Ia and 1 type III) required reintervention. Conclusion: In the
SURPASS registry, the use of the CTAG device with ACS showed promising outcomes
despite the challenging pathologies. The new delivery system enables a
controlled staged delivery with in situ adjustments during positioning,
facilitating the treatment of complex aortic disease.

Abstract
Purpose: To investigate the association between the bird-beak configuration (BBC), a wedge-shaped gap between the undersurface of a thoracic endograft and the lesser curvature of the arch after thoracic endovascular aortic repair (TEVAR), and postoperative outcome after TEVAR. Methods: The study was performed according to the PRISMA guidelines. The PubMed, EMBASE, and Cochrane databases were searched to identify all case series reporting BBC after TEVAR between 2006 and April 2018. Data analysis was performed considering the difference in the risk of complications for presence vs absence of BBC. After screening 1633 articles, 21 studies were identified that matched the selection criteria; 12 of these reported detailed information to investigate the postoperative outcome using proportion meta-analysis with a random effects model. The pooled risk difference is reported with the 95% confidence interval (CI). Heterogeneity of the included studies was assessed with the I2 statistic (low 25%, medium 50%, high 75%). Results: Complications occurred within a range of 0 to 72 months in 14.7% (95% CI 7.4% to 27.3%) of patients with BBC and in 6.3% (95% CI 2.5% to 15.4%) of patients without BBC. A cumulative incidence could not be assessed. The summary risk difference was 11.1% (95% CI −0.1% to 22.3%, p=0.052). There was significant heterogeneity ( I2=85.6%). The Egger test did not show evidence of publication bias (p=0.975). When specifically considering type Ia endoleak and endograft migration, the risk difference between BBC and non-BBC patients was 8.2% (95% CI 0.3% to 16.1%, p=0.042; I2=69.0%). The specific risk difference for endograft collapse/infolding and thrombosis was 3.7% (95% CI −3.5% to 11.1%, p=0.308; I2=10.2%). Conclusion: At present the literature does not provide statistical evidence to establish an overall prognostic value of the BBC. Nevertheless, the BBC appears to be associated with a high risk of type Ia endoleak and endograft migration, which warrants specific and long-term surveillance. Clinically relevant values for BBC grading should be established to perhaps define indications for preemptive treatment based on the presence of BBC only.

Abstract
BACKGROUND Thoracic endovascular aortic repair (TEVAR) currently represents the gold standard of treatment for thoracic aortic injury (TAI). Nevertheless, there is an ongoing debate surrounding its safety and subsequent cardiovascular effects. Our aim is to assess heart and vascular structure and function remodeling after TEVAR in TAI young patients. METHODS We evaluated 20 patients (18 men, age 41 ± 14 years, 11 treated with Gore CTAG, 9 with Medtronic Valiant) with office and 24-hr blood pressure (BP) with specific vascular stiffness analysis (Mobil-O-Graph), aortic diameters (computed tomography scan) and left ventricular mass index (LVMI echocardiogram). Evaluation was done after a median time of 5.0 ± 3.5 years from the trauma. RESULTS After TAI 12 patients (55%) developed hypertension. When patients were divided according to treating time, those treated for more than 3 years show higher LVMI, PWV, and ascending aorta dilatation. CONCLUSIONS Our study shows that TEVAR for TAI is associated with heart and vascular remodeling. The presence of TEVAR modifies aortic functional properties and could induce an increase in BP that can promote aortic and cardiac damage, even in young patients.

Abstract
BACKGROUND To evaluate the early safety and clinical performance of the new low-profile RelayPro Thoracic Stent-Graft System in patients with thoracic aortic disease. METHODS This was an international, prospective, single-arm study in patients diagnosed with thoracic aorta disease (aneurysm, pseudoaneurysm, dissection, penetrating atherosclerotic ulcer, or intramural hematoma) and treated with a RelayPro stent-graft (in bare stent and/or nonbare stent configurations). The primary endpoints were freedom from aneurysm or dissection-related mortality and stent-graft performance. RESULTS A total of 31 patients were treated with the RelayPro thoracic stent-graft between 2014 and 2015 at 8 sites in Italy and Spain. Mean age was 72.1 (±10.2) years and 77% were male, 74% with hypertension, and 42% with a history of smoking. Twenty-four (77%) had aneurysms (fusiform in 46%, saccular in 42%, pseudoaneurysm in 12%); 5 (16%) had penetrating atherosclerotic ulcer; and 2 (6%) had chronic Type B dissection. Mean vascular access diameter was 9.1 mm (6-13 mm); 7 patients (23%) had vascular access of 7 mm or less. Technical success was 100% (primary, 90%; assisted primary, 10%). Freedom from aneurysm/dissection-related mortality through 30 days was 100%. Freedom from device-related major adverse events through 30 days was 94%. At 1 year, there was 1 (3%) type Ib and 1 (3%) type II endoleak, 1 (3%) nonaneurysm-related late death, and 1 (3%) secondary intervention (to correct type Ib endoleak). CONCLUSIONS The RelayPro has a 3-4 French profile reduction to allow endovascular repair of thoracic aortic disease in patients with smaller anatomies. This study shows good initial stent-graft performance and a favorable early safety profile.

Abstract
BACKGROUND We compared outcomes of single-stage hybrid aortic arch replacement (frozen elephant trunk) versus 2-stage hybrid repairs with primary open arch procedures followed by thoracic endovascular stenting. METHODS This study reports a single-center retrospective review (2003 to 2016) of 118 patients undergoing hybrid repair of the aortic arch including 48 single-stage repairs versus 70 two-stage repairs. RESULTS Single-stage repair was performed in 48 patients, including 31 (64.6%) men and 17 (35.4%) women with a mean age of 64 ± 11 years and a 2-stage procedure was performed in 70 patients, including 42 (60%) men and 28 (40%) women with a mean age of 65.67 ± 13.3 years (p = 0.46). More emergent single-stage procedures were performed in 23 of 48 (47.9%) patients versus 2-stage procedures in 8 of 70 (11.43%) patients (p < 0.001). Between the single- and 2-stage groups, there was no difference in stroke (6.25% [3 of 48] versus 14.28% [10 of 70]; p = 0.23), spinal cord ischemia (4.16% [2 of 48] versus 5.7% [4 of 70]; p = 1.0), or 30-day mortality rate: 8 of 48 (16.7%) patients versus a combined 30-day mortality rate of the 2-stage procedure of 14.8% (4 of 70 [5.7%] at the first stage and 5 of 55 [9.1%] at the second stage; p = 0.56), respectively. After exclusion of the 30-day mortality, midterm survival was 86% at 1 to 2 years for single-stage patients versus 80% at 1 year and 46% at 2 years for the 2-stage patients (p = 0.0019). CONCLUSIONS Both single-stage and 2-stage hybrid arch replacements are effective approaches for treating complex aortic arch diseases. Early deaths and neurological outcomes in the single-stage group are comparable to those in the combined 2-stage group. Furthermore, in this series, patients who had a single-stage hybrid procedure had a higher survival rate at 2 years.

Abstract
Purpose: To analyze the results of isolated left subclavian artery (LSA) revascularization during thoracic endovascular aortic repair (TEVAR) using carotid-subclavian bypass (CSbp) or chimney grafts (CGs). Methods: A retrospective multicenter, observational study identified 73 patients (mean age 68±13 years, range 22–87; 56 men) with acute or chronic thoracic aortic lesions who underwent TEVAR with isolated LSA revascularization using either CSbp (n=42) or CGs (n=31) from January 2010 and February 2017. Primary endpoints were TEVAR-related mortality, postoperative stroke, freedom from type Ia endoleak, and LSA patency. Results: Primary technical success was achieved in all cases. Early TEVAR-related mortality was 4.2% (CSbp 2% vs CG 6%, p=0.571). Two (3%) patients had major ischemic strokes (one in each group). Mean follow-up was 24±21 months (range 1–72; median 15). Estimated freedom from TEVAR-related mortality was 93%±3% (95% CI 84.3% to 97.0%) at 12 and 36 months, with no significant difference between CSbp and CG (p=0.258). Aortic reintervention did not differ between the groups (CSbp 5% vs CG 6%, p=0.356); nor did freedom from type Ia endoleak (CSbp 98% vs CG 87%, p=0.134). Gutter-related endoleaks occurred in 4 (13%) CG patients, but none of the patients experienced sac enlargement or the need for reintervention and none died. Primary patency of the LSA was 100% for the entire group during the observation period. Conclusion: In our experience, LSA revascularization proved most satisfactory and equally effective with both the CSbp and CG techniques, without discernible differences at midterm follow-up.

Abstract
Background To report the experience of a single centre regarding the application of the triple-chimney technique using C-TAG with Viabahn or Excluder iliac extension devices for the endovascular management of aortic arch dilation diseases. Methods From July 2016 to August 2017, 7 patients (5 men; mean age 56.1±10.8 years) with aortic arch dilation diseases were treated with the triple-chimney technique. All patients were followed up at 1, 3, and 6 months and every 6 months thereafter. Results Six innominate arteries were deployed with Excluder iliac extensions and one with a Viabahn cover-stent. All the left common carotid arteries and left subclavian arteries were placed with Viabahn. Reverse chimney technique was applied in four patients. Three (42.0%) type I endoleaks were found on the final angiogram. Two were apparently reduced, and one disappeared after balloon dilation. The mean follow-up time was 15.7 months (9-20 months). All the type I endoleak was found disappeared within 3 months. One patient died of myocardial infarction at 6 months after discharge. No other complications such as stent-graft migration, occlusion, type II endoleak or neurological stroke occurred. Conclusions The use of C-TAG coupled with Viabahn or Excluder iliac extension is feasible and effective for the treatment of aortic arch dilatation diseases. However, more patients and longer follow-up time are required to verify its long-term safety and efficacy.

Abstract
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 Matching analysis revealed a significantly greater incidence of stroke in the HAR group but equivalent midterm outcomes in the hybrid group compared with the CTAR group.

Abstract
Background The aim of this study was to analyze device conformability in TEVAR of acute and chronic (a/c) type B aortic dissections (TBAD) using the Gore Conformable Thoracic Aortic Stent-graft (CTAG). Material/Methods From January 1997 to February 2014, a total of 90 out of 405 patients in our center received TEVAR for TBAD. Since November 2009, 23 patients (16 men; median age: 62 years) were treated with the CTAG. Indications were complicated aTBAD in 15 (65%) and expanding cTBAD in 8 (35%) patients. Primary endpoints were the assessment of device conformability by measuring the distance (D) from the radiopaque gold band marker (GM) at the proximal CTAG end to the inner curvature (IC) of the arch on parasagittal multiplanar reformations of CT angiography, as well as the evaluation of aortic diameter changes following TEVAR. Median follow-up was 13.3 months (range: 2 days to 35 months). Results Primary and secondary success rates were 91.3% (21/23) and 95.6% (22/23), respectively. There was 1 type Ia endoleak, retrograde dissection or primary conversion was not observed. Median GM-IC-D was 0 mm (range: 0 mm to 10 mm). GM-IC-D was associated with zone 2 placement compared to zone 3 (P=0.036). There was no association between GM-IC-D formation and arch type. In aTBAD cases the true lumen significantly increased after TEVAR (P=0.017) and the false lumen underwent shrinkage (P=0.025). In cTBAD patients the false lumen decreased after TEVAR (P=0.036). Conclusions The CTAG shows favorable conformability and wall apposition in challenging arch pathologies such as TBAD.
