[PMID: 39128706 DOI: 10.1016/j.hjc.2024.08.006] [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: 03/02/2024] [Revised: 07/10/2024] [Accepted: 08/04/2024] [Indexed: 08/13/2024] Open
Abstract
OBJECTIVE Aortic dissection remains a life-threatening condition necessitating accurate diagnosis and timely intervention. This study aimed to investigate phenotypic heterogeneity in patients with Stanford type B aortic dissection (TBAD) through machine learning clustering analysis of cardiovascular computed tomography (CT) imaging. METHODS Electronic medical records were collected to extract demographic and clinical features of patients with TBAD. Exclusion criteria ensured homogeneity and clinical relevance of the TBAD cohort. Controls were selected on the basis of age, comorbidity status, and imaging availability. Aortic morphological parameters were extracted from CT angiography and subjected to K-means clustering analysis to identify distinct phenotypes. RESULTS Clustering analysis revealed three phenotypes of patients with TBAD with significant correlations with population characteristics and dissection rates. This pioneering study used CT-based three-dimensional reconstruction to classify high-risk individuals, demonstrating the potential of machine learning in enhancing diagnostic accuracy and personalized treatment strategies. Recent advancements in machine learning have garnered attention in cardiovascular imaging, particularly in aortic dissection research. These studies leverage various imaging modalities to extract valuable features and information from cardiovascular images, paving the way for more personalized interventions. CONCLUSION This study provides insights into the phenotypic heterogeneity of patients with TBAD using machine learning clustering analysis of cardiovascular CT imaging. The identified phenotypes exhibit correlations with population characteristics and dissection rates, highlighting the potential of machine learning in risk stratification and personalized management of aortic dissection. Further research in this field holds promise for improving diagnostic accuracy and treatment outcomes in patients with aortic dissection.

Abstract
OBJECTIVE The study was to figure out the feasibility, efficacy, and safety of a single-branched stent graft, namely Castor, in combination with fenestration or chimney in the context of aortic arch lesions presenting with aberrant subclavian artery (ASA) and/or Kommerell's diverticulum (KD). METHODS All consecutive patients with aortic arch lesions and ASA and/or KD receiving Castor from June 2018 to June 2023 were investigated. RESULTS Incorporating 18 patients, the study encompassed 11 cases with KD, 3 cases with dysphagia; 2 cases of right-sided aortic arch with left-sided aberrant left subclavian artery (ALSA), and 16 cases of left-sided aortic arch with right-sided aberrant right subclavian artery (ARSA). The mean operation time was 132±23 minutes. The mean measured proximal aortic diameter was 30.9±1.6 mm, and proximal diameter of Castor stent was 34 (32, 34.5) mm, with oversize of 9.1±1.6%; the mean measured branch diameter was 8.8±0.97 mm, and branch diameter of Castor stent was 10 (8, 10) mm, with oversize of 0.86±0.57 mm. Technical success rate was 100%, and no in-hospital mortality, no stroke, and no endoleak were identified. One (5.6%) case with spinal cord ischemia and one (5.6%) case with poor healing of operative site were identified. During the follow-up period, no aortic-related death or secondary intervention was recorded. The maximal aortic diameter was significantly reduced at the sixth postoperative month (padj=0.031); KD diameter was significantly reduced at the third (padj=0.001) and sixth (padj<0.001) postoperative month. CONCLUSION Totally endovascular repair of aortic arch lesions with ASA and KD via Castor stent in combination with fenestration or chimney is feasible, effective, and safe, which can achieve an encouraging medium-term outcome and provide excellent remodeling at the lesions. CLINICAL IMPACT Single branched stent in combination with fenestration or chimney achieved a sufficient proximal landing zone and provided an encouraging medium-term outcome in this retrospective review of 18 patients receiving endovascular treatment of pathological aortic arch with aberrant subclavian artery and/or Kommerell's diverticulum. The authors suggest this time-saving and efficient technique to establish systematic experience for the treatment in this kind of patients.

Abstract
Objective To evaluate the outcomes of thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD) with aberrant right subclavian artery (ARSA). Methods A retrospective analysis was conducted on patients with TBAD and ARSA who underwent TEVAR between the period of January 2017 and December 2022. Patient demographics, computed tomography angiography (CTA) measurements, surgical procedures, and postoperative outcomes were reviewed. Results A total of 9 patients (6 males and 3 females) were included in the study. 4 ARSA were reconstructed, 3 by periscope technique and 1 by in vitro fenestration technique. 3 left subclavian arteries (LSA) were reconstructed, 1 by the chimney technique and 2 by the single-branched stent technique. 2 patients underwent reconstruction of both ARSA and LSA. The overall technical success rate was 100%, with no occurrences of stroke, paraplegia, or mortality within 30 days. 1 patient experienced immediate type Ia endoleak, which resolved after 3 months. 1 patient developed weakness in the right upper limb, while 1 patient presented mild subclavian steal syndrome (SSS); both cases showed recovery during follow-up. The average follow-up duration was 35.6 ± 11.1 months, during which no reinterventions, deaths, or strokes were observed. Conclusion Our limited experience involving 9 patients demonstrates that early and mid-term outcomes of TEVAR for the treatment of TBAD with ARSA are satisfactory.

Abstract
OBJECTIVE To compare the early and midterm outcomes of three different strategies for an isolated left vertebral artery on the arch (LVoA) revascularisation during thoracic endovascular aortic repair (TEVAR) with a proximal zone 2 landing. METHODS Between January 2016 and December 2021, 67 patients with LVoA and aortic arch pathologies who underwent zone 2 landing TEVAR at four medical centres were enrolled. These patients were divided into three groups for comparison: the novel chimney (group A, n = 28) with the right brachial-left brachial through and through (RLT) procedure; in vitro fenestration (group B, n = 24); and transposition (group C, n = 15). The flow direction and velocity of the LVoA was examined by Doppler ultrasound in the pre-, intra-, and post-operative periods. Primary outcomes were all cause mortality and new neurological symptoms. RESULTS No deaths or new neurological symptoms occurred within 30 days. Early type Ia endoleak rates were 18% (n = 5), 17% (n = 4), and 0% in groups A, B, and C, respectively (p = .22). All patients had antegrade flow of the LVoA. The mean ± standard deviation duration of follow up was 63.6 ± 4.0 months. No deaths were observed during follow up. The rates of new neurological symptoms were 0%, 8%, and 33% in groups A, B, and C, respectively. The rates of midterm type Ia endoleak were 7%, 12%, and 0% in groups A, B, and C, respectively (p = .35). Bidirectional flow rates in the LVoA were 0%, 21%, and 27% in groups A, B, and C, respectively (p = .021). Two (8%) and three (20%) patients in groups B and C underwent a secondary procedure because of mild dizziness, but this was not necessary in group A (p = .058). CONCLUSION The novel chimney technique of the RLT procedure may be feasible for patients with a LVoA requiring zone 2 anchoring. Accurate determination of the safety and feasibility of this novel technique requires larger sample sizes and longer follow up.

AORTA (STAMFORD, CONN.) 2023; 11:20-28. [PMID: 36848908 PMCID: PMC9970753 DOI: 10.1055/s-0042-1757948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Accepted: 07/06/2022] [Indexed: 06/18/2023]
Abstract
An aberrant right subclavian artery (ARSA) is the most common congenital variant of the aortic arch. Usually, this variation is largely asymptomatic, but sometimes it may be involved in aortic dissection (AD). Surgical management of this condition is challenging. The therapeutic options have been enriched in recent decades by establishing individualized endovascular or hybrid procedures. Whether these less invasive approaches bear advantages, and how they have changed the treatment of this rare pathology, is still unclear. Therefore, we conducted a systematic review. We performed a review of literature from the past 20 years (from January 2000 until February 2021) complying with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. All reported patients treated for Type B AD in the presence of an ARSA were identified and classified into three groups according to the received therapy (open, hybrid, and total endovascular). Patient characteristics, as well as in-hospital mortality, and major and minor complications were determined and statistically analyzed. We identified 32 relevant publications comprising 85 patients. Open arch repair has been offered to younger patients, but significantly less often in symptomatic patients needing urgent repair. Therefore, the maximum aortic diameter was also significantly larger in the open repair group compared with that in the hybrid or total endovascular repair group. Regarding the endpoints, we did not find significant differences. The literature review revealed that open surgical therapies are preferred in patients presenting with chronic dissections and larger aortic diameters, most likely because they are unsuitable for endovascular aortic repair. Hybrid and total endovascular approaches are more often applied in emergency situations, where aortic diameters remain smaller. All therapies demonstrated good, early, and midterm outcomes. But, these therapies carry potential risks in the long term. Therefore, long-term follow-up data are urgently needed to validate that these therapies are sustainable.

Abstract
BACKGROUND Aberrant subclavian artery (AScA) with or without associated Kommerell's diverticulum (KD) is the most frequently encountered anomaly of the aortic arch, it may be life threatening, especially when associated with aneurysmal degeneration. The best management is still debated and depends on many clinical and anatomical factors. A systematic review was conducted to assess the current evidence on the treatment options and their efficacy and safety for AscA and KD repairs. METHODS A literature search in PubMed and Cochrane Library was performed, and articles that were published from January 1947 to August 2021 reporting on AscA and KD management were identified. Multicenter studies, single-center series, and case series with three or more patients were considered eligible in the present review. A comparison of outcomes of patients who underwent open surgery (OS), a hybrid approach (HA), and total endovascular repair (ER) (ie, 30-day mortality and stroke were analyzed when available and compared among the three groups (P < .05; Benjamini and Hochberg-adjusted P < .05; Bonferroni-adjusted P < .05). Titles, abstracts, and full texts were evaluated by two authors independently. Primary outcomes included survival rate, perioperative stroke, arm ischemia, and spinal cord ischemia. Endoleak, in the case of HA and ER, and reintervention rates were considered outcomes. RESULTS Three hundred thirty-one articles were initially evaluated and 30 studies, totaling 426 patients treated for AScA with 324 KD, were included. Of the 426 patients, 241 were male (56.5%), and the mean patient age was 57.9 ± 12.0 years. The approach was OS in 228 patients, HA in 147 patients, and ER in 51. Dysphagia was the most common presentation in 133 cases. Aortic rupture was observed in 16 of the 426 patients (3.8%), including 14 AScA/KD (3.3%) aneurysm rupture. KD maximum diameter varied widely from 12.6 to 63.6 mm. The overall 30-day mortality was 20 (4.7%) (OS group 8/228 [3.5%]; HA group 10/147 [6.8%]; ER 2/51 [3.9%]; P = NS). The overall stroke rate was 4.9% (21/426) (OS group 10/228 [4.4%]; HA group 6/147 [4.1%]; ER group 5/51 [9.8%]; P = NS), including nine transient and nondisabling neurological deficits. Overall secondary procedures for complications were reported in 36 of the 426 cases (8.4%), mostly owing to endoleak. Follow-up varied from 13 to 74 months. CONCLUSIONS This systematic review assessed the current outcomes of the three types of therapeutic management for AScA and KD and demonstrated that they are all relatively safe and effective, providing satisfactory early and midterm outcomes. Long-term outcomes are warranted, especially for total ERs since the long-term durability of stent grafts remains unknown.

Abstract
INTRODUCTION The management of Kommerell's Diverticulum (KD) has evolved from open surgical resection and graft replacement of the aorta, to endovascular repair in asymptomatic patients due to its recognized possible sequelae - aortic rupture and dissection. Despite these technical advances, standard indications for intervention and treatment algorithms remain unclear. We will present our single-center experience in the treatment of KD, supporting a multidisciplinary endovascular-first approach. METHODS All patients who underwent thoracic endovascular aortic repair (TEVAR) for KD between 2017 and 2020 were retrospectively identified from a prospectively maintained institutional surgery database. Chart review was used to characterize presenting symptoms, interventions, technical results, and complications. Revascularization was performed using carotid-axillary bypass. Routine endovascular subclavian artery occlusion was employed to eliminate retrograde diverticulum perfusion and avoid open ligation. RESULTS 8 patients were identified, including 6 females and 2 males between the ages of 44-76. Patients presented with dysphagia (n = 3), acute embolic stroke (n = 1), transient ischemic attack (TIA) (n = 1), upper extremity embolization (n = 1), and acute type B aortic dissection (n = 1). One patient had a prior incomplete open repair that was successfully treated endovascularly. Another patient had a mediastinal neoplasm infiltrating an incidental aberrant subclavian artery and KD. All cases had symptomatic improvement and successful endovascular repair as demonstrated on post-operative imaging. Perioperative complications included percutaneous access site pseudoaneurysm (n = 2), stroke (n = 1), and subclavian artery rupture immediately recognized and treated (n = 1). There was no perioperative mortality. CONCLUSION Endovascular techniques have resulted in technical success and symptomatic improvement for KD without open thoracotomy or sternotomy. Significant rates of endovascular complications and paucity of long-term durability data should be considered. Until formal criteria for repair are established, early application of TEVAR using a consistent multi-specialty approach may mitigate the risk of unpredictable aortic complications in these patients while avoiding the accepted morbidity and mortality of open surgery.

Abstract
Objective The aim of the study was to investigate surgical modalities and outcomes in patients with type A aortic dissection involving arch anomalies. Method Patients with type A aortic dissection who underwent surgical treatment at our center between January 2017 and 31 December 2020 were selected for this retrospective analysis. Data including computed tomography (CT), surgical records, and cardiopulmonary bypass records were analyzed. Perioperatively survived patients were followed up, and long-term mortality and aortic re-interventions were recorded. Result A total of 81 patients with arch anomalies were included, 35 with “bovine” anomalies, 23 with an aberrant right subclavian artery, 22 with an isolated left vertebral artery, and one with a right-sided arch + aberrant left subclavian artery. The strategies of arch management and cannulation differed according to the anatomic variation of the aortic arch. In total, seven patients (9%) died after surgery. Patients with “bovine” anomalies had a higher perioperative mortality rate (14%) and incidence of neurological complications (16%). Overall, four patients died during the follow-up period, with a 6-year survival rate of 94.6% (70/74). A total of four patients underwent aortic re-intervention during the follow-up period; before the re-intervention, three received the en bloc technique (13.6% 3/22) and one received hybrid therapy (11.1% 1/9). Conclusion With complete preservation and reconstruction of the supra-arch vessels, patients with type A aortic dissection combining arch anomalies can achieve a favorable perioperative prognostic outcome. Patients who received the en bloc technique are more likely to require aortic re-intervention than patients who underwent total arch replacement with a four-branched graft vessel. Cannulation strategies should be tailored according to the variation of anatomy, but routine cannulation with the right axillary artery can still be performed in most patients with arch anomalies, even for patients with an aberrant right subclavian artery.

Abstract
OBJECTIVE The arterial morphology in aberrant subclavian artery (ASA) patients and its association with type B aortic dissection are important for treatment and prevention. This study examined the arterial morphology of ASA patients with type B dissection and evaluated its association with type B dissection in vivo. METHODS The presence of ASA and type B dissection was screened from patients with aortic dissection receiving computed tomography angiography (CTA) from January 2011 to May 2021. ASA patients with type B dissection (Group 1, n=16), clinically-matched counterparts without type B dissection (Group 2, n=32) and clinically-matched type B dissection subjects without ASA (Group 3, n=32) were measured for the angles of ascending aorta, aortic arch, aortic deviation, and the diameters of ascending aorta, aortic arch, ASA ostium and middle ASA segment. The correlation between ASA morphology and type B dissection was analyzed by variance analysis or Wallies H test. RESULTS Compared with Group 2, Group 1 reported a sharper ascending aortic angle (131.5o±13.7o vs. 148.1o±7.8o, P=0.001), larger aortic deviation angle in plane 2 (28.2o±6.0o vs. 22.1o±7.2o, P=0.005) and plane 3 (26.4 o±7.3o vs. 21.8o±6.3o, P=0.028). Similarly, Group 1 displayed a greater diameter in the ascending aorta, aortic arch, and the ostium and middle of ASA (38.3±4.1mm vs. 33.6±4.5mm, P=0.001; 34.0±9.3mm vs. 26.2±2.9mm, P=0.004; 20.3±9.3mm vs. 14.0±3.2mm, P=0.018; 10.8±2.3mm vs. 9.0±1.5mm, P=0.002, respectively), without a significant difference in the aortic arch angle. Compared with Group 3, Group 1 showed a sharper ascending aortic angle (131.5o±13.7o vs. 142.5o±11.7o, P=0.026) and smaller aortic deviation angle in plane 1 (21.7o±6.2o vs. 28.9o±6.2o, P=0.04) and plane 3 (26.4o±7.3o vs. 21.8o±6.3o, P=0.007), though with no significant difference in the aortic arch angle, aortic deviation angle in plane 2, and ascending aortic diameter. CONCLUSIONS The diameters of the ostium and middle segment of ASA and ascending aorta and the angles of ascending aorta and aortic deviation are potential risk factors for type B dissection in ASA patients, which may provide new insights into the mechanism of type B dissection in patients with ASA.

Abstract
Objectives To evaluate the in-hospital and later outcomes of thoracic endovascular aortic repair (TEVAR) for type B intramural hematoma (TBIMH) combined with an aberrant subclavian artery (aSCA). Methods In the period from January 2014 to December 2020, 12 patients diagnosed with TBIMH combined with aSCA and treated by TEVAR were enrolled in this retrospective cohort study, including 11 patients with the aberrant right subclavian artery (ARSA) and 1 with an aberrant left subclavian artery (ALSA). A handmade fenestrated stent-graft or chimney stent or hybrid repair was performed when the proximal landing zone was not enough. Results The mean age of all the patients was 59.2 ± 7.6 years, and 66.7% of patients were men. There were 4 patients with Kommerell's diverticulum (KD). The procedures in all 12 patients were technically successful. There was one case each of postoperative delirium, renal impairment, and type IV endoleak after TEVAR. During follow-up, 1 patient died of acute pancreatitis 7 months after TEVAR. The overall survival at 1, 3, and 5 years for the patients was 90.9, 90.9, and 90.9%, respectively. KD was excluded in 2 patients, and the handmade fenestrated stent-graft was applied in the other 2 patients to preserve the blood flow of the aSCA. No neurological complications developed and no progression of KD was observed during the follow-up. Conclusion Thoracic endovascular aortic repair for patients with aSCA and TBIMH is promising. When KD was combined, we could exclude KD or preserve the blood flow of aSCA with regular follow-up for the diverticulum according to the size of the KD.

Abstract
BACKGROUND Type B aortic dissection (TBAD), is defined as a dissection involving the aorta distal to left subclavian artery with the ascending aorta and the aortic arch not affected. TBAD is classified due to the time frame and presence of complications. Complicated TBAD (co-TBAD) patients have a greater mortality rate than uncomplicated TBAD (un-TBAD) and thoracic endovascular aortic repair (TEVAR) is considered the gold-standard intervention for these clinical challenges. METHODS We undertook a systematic review of the literature regarding TEVAR intervention in co-TBAD and un-TBAD. A comprehensive search was undertaken across four major databases and was evaluated and assessed until June 2020. RESULTS A total of 16,104 patients were included in the study (7772 patients co-TBAD and 8352 un-TBAD). A significantly higher proportion of comorbidities were seen in co-TBAD patients compared with un-TBAD. Acute dissection was more frequent in the co-TBAD group (73.55% vs. 66.91%), while chronic dissection was more common in un-TBAD patients (33.8% vs. 70.73%). Postprocedure stroke was higher in co-TBAD (5.85% vs. 3.92%; p < .01), while postprocedural renal failure was higher in un-TBAD patients (7.23 vs. 11.38%; p < .01). No difference was observed in in-hospital mortality however the 30 days mortality was higher in the co-TBAD group. One-year survival was higher in the uncomplicated group but this difference was not observed in the 5-year survival. CONCLUSION In our analysis we can appreciate that despite significantly higher comorbidities in the co-TBAD cohort, there was no difference in in-hospital mortality between the two groups and the 5-year survival did not have any difference.

Abstract
Managing type B aortic dissection (TBAD) involving Kommerell's diverticulum (KD), aberrant right subclavian artery (ARSA), and isolated left vertebral artery (ILVA), is extremely challenging. As treatment, we described a one-stage hybrid technique combined with thoracic endovascular aortic repair (TEVAR) with open surgery through a supraclavicular incision. A 57-year-old man with TBAD and the three anomalies successfully underwent hybrid TEVAR. A side-to-side artificial bypass between the ARSA and the right common carotid artery was established through a right supraclavicular incision before TEVAR. The release of the stent-graft was designed from the distal aortic ostium to the left common carotid artery (LCCA) to cover the ILVA, ARSA, and left subclavian artery (LSA). Then, the ILVA and LSA were transposed to the LCCA through a left supraclavicular incision. Intraoperative angiography confirmed complete false lumen exclusion and KD, with all branches patent and without endoleaks. Computed tomography angiography 7 days and 1 year postoperatively demonstrated well-perfused ARSA, LSA, and ILVA, and a fully expanded stent-graft with no endoleaks, migration, disconnection, or stenosis. TBAD involving KD, ARSA, and ILVA in one case is rare. This is the first report to treat this pathology with a one-stage supraclavicular hybrid procedure.

Abstract
OBJECTIVE In this retrospective study, we presented the results of Castor single-branched stent-graft in a small series of patients with acute type B aortic syndrome and aberrant right subclavian artery (ARSA). METHODS Between January 2019 and November 2019, 5 patients were diagnosed with acute type B aortic syndrome and ARSA (4 patients with intramural hematoma and ARSA, 1 patient with type B aortic dissection and ARSA). All the patients underwent thoracic endovascular aortic repair (TEVAR) using Castor single-branched stent-graft. In-hospital and 3-month outcomes were collected. RESULTS The mean operative time was 116 ± 20.43 minutes (range 90-145). All the TEVAR procedures were successfully performed without conversion to open surgery (100% success rate). All the ARSAs of the 5 patients were revascularized in situ by Castor single-branched stent-grafts. No deaths and complications were observed in the 3-month follow-up. The maximal diameters of diseased aortas in the 4 patients with IMH decreased 3 months after TEVAR. The false lumen in the graft-covered segment was completely thrombosed in the patient with type B aortic dissection. CONCLUSIONS Castor single-branched stent-graft may be a good choice in treatment of acute type B aortic syndrome and aberrant right subclavian artery.

Abstract
OBJECTIVE Aberrant subclavian artery (ASA), a well-described aortic arch anomaly, is frequently associated with dysphagia and development of Kommerell diverticulum (KD) with aneurysmal degeneration. Historically, open repair has been performed, which can be associated with significant morbidity. More recently, hybrid approaches using different arch vessel revascularization techniques in combination with thoracic endovascular aortic repair (hybrid TEVAR) have been described, but there is a paucity of literature describing outcomes. The objective of this analysis was to describe our experience with management of complicated ASAs using hybrid TEVAR, further adding to the literature describing approaches to and outcomes of hybrid ASA repair. METHODS A retrospective, single-institution review was performed of all patients treated for ASA complications using hybrid TEVAR (2002-2018). The primary end point was technical success, defined as absence of type I or type III endoleak intraoperatively and within 30 days postoperatively. Secondary end points included complications, reintervention, and survival. Centerline measurement of KD diameters (maximum diameter = opposing aortic outer wall to diverticulum apex) was employed. Kaplan-Meier methodology was used to estimate secondary end points. RESULTS Eighteen patients (1.4% of 1240 total TEVAR procedures; male, 67%; age, 59 ± 13 years) were identified (left-sided arch and right ASA, 94% [n = 17]; right-sided arch and left ASA, n = 1 [6%]; retroesophageal location and associated KD, 100%); median preoperative KD diameter was 60 mm (interquartile range [IQR], 37-108 mm). Operative indications included diverticulum diameter (61%), dysphagia (17%), rupture (11%), rapid expansion (6%), and endoleak after TEVAR (6%). All procedures used some combination of supraclavicular revascularization and TEVAR (staged, 50% [n = 9]), whereas partial open arch reconstruction was used in 17% (n = 3). There were no perioperative deaths or spinal cord ischemic events. Major complications occurred in 22% (n = 4): nondisabling stroke, one; arm ischemia, one; upper extremity neuropathy, one; and iatrogenic descending thoracic aortic dissection, one. Technical success was 83%, but 44% (n = 8) had an endoleak (type I, n = 3; type II, n = 5 [intercostal, n = 2; aneurysmal subclavian artery origin, n = 3]) during follow-up (median, 4 months; IQR, 1-15 months). Two endoleaks resolved spontaneously, three were treated, and three were observed (1-year freedom from reintervention, 75% ± 10%). Median KD diameter decreased by 7 mm (IQR, 1-12 mm), and 78% (n = 14) experienced diameter reduction or stability in follow-up. The 1- and 3-year survival was 93% ± 6% and 84% ± 10%, respectively. CONCLUSIONS Hybrid open brachiocephalic artery revascularization with TEVAR appears to be safe and reasonably effective in management of ASA complications as evidenced by a low perioperative complication risk and reasonable positive aortic remodeling. However, endoleak rates raise significant concerns about durability. Therefore, if this technique is employed, the mandatory need for surveillance and high rate of reintervention should be emphasized preoperatively. This analysis represents a relatively large series of a hybrid TEVAR technique to treat ASA complications, but greater patient numbers and longer follow-up are needed to further establish the role of this procedure.

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
PURPOSE To evaluate the early and midterm outcomes of endovascular repair of Stanford type B aortic dissection (TBAD) with an aberrant right subclavian artery (ARSA). MATERIALS AND METHODS From November 2012 to July 2018, 15 patients (13 male, 2 female) who had TBAD with ARSA underwent total endovascular repair, including thoracic endovascular aortic repair (TEVAR), left subclavian artery (LSA) chimney technique, LSA fenestration technique, and double chimney technique (LSA chimney and ARSA periscope). The mean age was 55 years. Kommerell diverticulum (KD) occurred in 2 patients, which were covered by means of oversized aortic stents. All patients had preoperative imaging examinations for assessing cerebral blood flow and the dominant vertebral arteries. RESULTS All procedures were completed successfully. There was no in-hospital mortality. The mean procedural time was 98 ± 40 minutes (range 50-190). The mean preoperative diameters of the maximum descending aorta, false lumen, and true lumen in the descending aorta versus postoperative were 37 ± 10 mm (range 28-67), 18 ± 9 mm (range 9-41), and 19 ± 6 mm (range 10-35) versus 34 ± 9 mm (range 25-64), 5 ± 8 mm (range 0-28), and 28 ± 5 mm (range 19-37), respectively. Right upper extremity weakness was observed in 2 patients, which recovered gradually during follow-up. Immediate type Ia endoleak was detected in 1 patient. The mean follow-up time was 33 ± 20 months. During follow-up, no ARSA steal syndrome, spinal cord ischemia, or strokes were not observed. CONCLUSIONS Endovascular treatment for TBAD with ARSA was feasible and safe with a satisfactory midterm follow-up outcome.
