Yuan Z, Zhang L, Cai F, Wang J. Clinical outcomes and aortic remodeling after Castor single-branched stent-graft implantation for type B aortic dissections involving left subclavian artery. Front Cardiovasc Med 2024; 11:1370908. [PMID: 38873267 PMCID: PMC11169613 DOI: 10.3389/fcvm.2024.1370908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Accepted: 04/29/2024] [Indexed: 06/15/2024] Open
Abstract
Background The left subclavian artery (LSA) can be intentionally covered by a stent graft to acquire adequate landing zones for a proximal entry tear near the LSA during thoracic endovascular aortic repair (TEVAR). The Castor single-branched stent graft is designed to treat type B aortic dissection (TBAD) to retain the LSA during TEVAR. This study investigates clinical outcomes, aortic remodeling, and abdominal aortic perfusion patterns after TEVAR with the novel Castor device. Methods From November 2020 to June 2023, 29 patients with TBAD involving the LSA were treated with the Castor single-branched stent graft. In-hospital clinical outcome and aortic computed tomography angiography (CTA) data were analyzed. CTA was performed preoperatively and at follow-up to observe stent morphology; branch patency; endoleak; change in true lumen (TL), false lumen (FL), and transaortic diameters; and abdominal aortic branch perfusion pattern. Results The technical success rate was 96.6%. One failure was that the branch section did not completely enter the LSA and the main body migrated distally. No in-hospital mortality, paraplegia, or stroke occurred. During follow-up, one type Ib endoleak, four distal new entry tears, and one recurrent type A dissection arose from a new entry tear at the ascending aorta, no stent migration was observed, and the branch patency rate was 100%. At the thoracic aorta, TL diameters significantly increased, FL diameters markedly decreased, and FL was partially or completely thrombosed in most patients at follow-up. At the abdominal aorta, we observed 33.3% of TL growth and 66.7% of TL stabilization or shrinkage. The initial TL ratio at iliac bifurcation negatively predicted abdominal TL growth after TEVAR with a cutoff of 21.0%. Of the 102 abdominal aortic branches, 94.1% of the branches showed no change in perfusion pattern, 3.9% of the branches had an increased TL perfusion, and 2.0% of the branches had an increased FL contribution. Conclusion The Castor unibody single-branched stent graft offers an efficient endovascular treatment for TBAD involving the LSA. TEVAR with the Castor device effectively induced thoracic FL thrombosis and thoracic TL enlargement and resulted in abdominal TL growth when the initial TL ratio at iliac bifurcation is less than 21.0%. Abdominal aortic branch perfusion patterns remain relatively stable after TEVAR with the Castor stent graft.

Abstract
OBJECTIVES Our goal was to access early and mid-term outcomes of a gutter-plugging chimney stent graft for treatment of Stanford type B aortic dissections in the clinical trial Prospective Study for Aortic Arch Therapy with stENt-graft for Chimney technology (PATENCY). METHODS Between October 2018 and March 2022, patients with Stanford type B aortic dissections were treated with the Longuette chimney stent graft in 26 vascular centres. The efficiency and the incidence of adverse events over 12 months were investigated. RESULTS A total of 150 patients were included. The technical success rate was 99.33% (149/150). The incidence of immediate postoperative endoleak was 5.33% (8/150, type I, n = 6; type II, n = 1; type IV, n = 1) neurologic complications (stroke or spinal cord ischaemia); the 30-day mortality was 0.67% (1/150) and 1.33% (2/150), respectively. During the follow-up period, the median follow-up time was 11.67 (5-16) months. The patent rate of the Longuette graft was 97.87%. Two patients with type I endoleak underwent reintervention. The follow-up rate of the incidence of retrograde A type aortic dissection was 0.67% (1/150). There was no paraplegia, left arm ischaemia or stent migration. CONCLUSIONS For revascularization of the left subclavian artery, the Longuette chimney stent graft can provide an easily manipulated, safe and effective endovascular treatment. It should be considered a more efficient technique to prevent type Ia endoleak. Longer follow-up and a larger cohort are needed to validate these results. CLINICAL TRIAL REGISTRY NUMBER NCT03767777.

Predicting the need for subclavian artery revascularization in thoracic endovascular aortic repair: A systematic review and meta-analysis. J Vasc Surg 2024:S0741-5214(24)00985-6. [PMID: 38621636 DOI: 10.1016/j.jvs.2024.04.023] [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: 02/06/2024] [Revised: 03/21/2024] [Accepted: 04/09/2024] [Indexed: 04/17/2024]
Abstract
OBJECTIVE This systematic review and meta-analysis aims to investigate the effectiveness of left subclavian artery revascularization compared with non-revascularization in thoracic endovascular aortic repair, and to summarize the current evidence on its indications. METHODS A computerized search was conducted across multiple databases, including MEDLINE, SCOPUS, Cochrane Library, and Web of Science, for studies published up to November 2023. Study selection, data abstraction, and quality assessment (using the Newcastle-Ottawa Scale) were independently conducted by two reviewers, with a third author resolving discrepancies. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using random-effects models and publication bias was assessed using funnel plots. RESULTS In the 76 included studies, left subclavian artery revascularization was associated with reduced risks of stroke (OR, 0.67; 95% CI, 0.45-0.98; n = 15,331), spinal cord ischemia (OR, 0.75; 95% CI, 0.56-0.99; n = 11,995), and arm ischemia (OR, 0.09; 95% CI, 0.01-0.59; n = 8438). No significant reduction in paraplegia (OR, 0.56; 95% CI, 0.21-1.47; n = 1802) or mortality (OR, 0.77; 95% CI, 0.53-1.12; n = 11,831) was observed. Moreover, the risk of endoleak was comparable in both groups (OR, 1.25; 95% CI, 0.55-2.84; P = .60; n = 793), whereas the risk of reintervention was significantly higher in the revascularization group (OR, 1.98; 95% CI, 1.03-3.83; P = .04; n = 272). Both groups had similar risks of major (OR, 0.45; 95% CI, 0.19-1.09; P = .08; n = 1113), minor (OR, 0.21; 95% CI, 0.01-3.45; P = .27; n = 183), renal (OR, 0.61; 95% CI, 0.12-3.06; P = .55; n = 310), and pulmonary (OR, 0.59; 95% CI, 0.16-2.15; P = .42; n = 8083) complications. The most frequent indications for left subclavian artery revascularization were primary prevention of spinal cord ischemia, augmentation of the landing zone, and primary stroke prevention. CONCLUSIONS Left subclavian artery revascularization in thoracic endovascular aortic repair was associated with reduced neurological complications but was not found to impact mortality. The study highlights important indications for revascularization as well as significant predictors of complications, providing a basis for clinical decision-making and future research.

Abstract
We present a rare manifestation of a common pathology: left sided sensorineural hearing loss secondary to subclavian steal syndrome after thoracic endovascular aortic repair for complicated acute aortic dissection. We describe the vascular physiology that can result in unilateral hearing loss and provide a brief review of subclavian steal syndrome. This case report highlights the importance of avid clinical recognition of an atypical presentation of a common vascular disease.

Abstract
AIM The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. STRUCTURE Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

Left subclavian artery revascularization is associated with less neurologic injury after endovascular repair of acute type B aortic dissection. J Vasc Surg 2023; 78:1170-1179.e2. [PMID: 37524152 DOI: 10.1016/j.jvs.2023.07.051] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 07/16/2023] [Accepted: 07/22/2023] [Indexed: 08/02/2023]
Abstract
OBJECTIVE The aim of this study was to analyze patients with acute type B aortic dissection (aTBAD) requiring thoracic endovascular aortic repair (TEVAR) with left subclavian artery (LSA) coverage to determine whether LSA revascularization decreased the risk of neurologic complications. METHODS The national Vascular Quality Initiative TEVAR module was queried for all procedures performed between 2014 and 2021. Patients presenting with aortic aneurysms or aortic ruptures were excluded from the analysis. Patients were divided into two groups according to whether their LSA was revascularized (prior to or during TEVAR) or not. Univariate followed by multivariate analysis was used to account for possible confounders and evaluate the association of LSA revascularization with the primary outcome of neurologic injury (stroke or spinal cord ischemia). RESULTS Among patients who had TEVAR for aTBAD, 501 patients had the LSA covered. The LSA was revascularized prior to or concomitant with TEVAR in 28% of these patients (n = 139). Average age was 57 years, and 73% (n = 366) were male. Neurologic injury developed in 88 patients (18%). On univariate analysis, patients who had their LSA revascularized were significantly less likely to develop neurologic injury (10% vs 20%; P < .01). This association persisted after accounting for potential confounders (odds ratio, 0.4; P = .02). No significant difference was seen when comparing 30-day or 1-year mortality between patients who had LSA revascularization and those who did not. Follow-up averaged 1.9 years (range, 0-8.1 years). Long-term survival did not differ between the two groups on Kaplan-Meier analysis. CONCLUSIONS In this study of patients with aTBAD who underwent LSA coverage during TEVAR, the addition of a LSA revascularization procedure was associated with a significantly lower incidence of neurological injury including spinal cord ischemia and/or stroke.

Ann Vasc Surg 2023; 91:266-274. [PMID: 36642166 DOI: 10.1016/j.avsg.2023.01.009] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/21/2022] [Accepted: 01/05/2023] [Indexed: 01/13/2023]
Abstract
BACKGROUND In situ laser fenestrated endovascular aortic repair (L-FEVAR) is a novel and creative solution for complex aortic pathologies in the urgent and emergency setting. Outcomes of this technique, however, are poorly reported. We sought to evaluate the efficacy, safety, and outcomes of L-FEVAR in aortic arch pathologies. METHODS A systematic literature review and analysis were conducted in accordance with the preferred reporting items for systematic reviews and meta-analyses and Cochrane guidelines. A search was conducted using Google, PubMed, and Scopus to identify studies evaluating L-FEVAR. Two independent reviewers determined study inclusion. Case reports and series including < 10 patients were excluded. Reviewers also assessed the methodological quality and extracted data regarding outcomes. A meta-analysis of endoleak event rates was conducted using a fixed-effect model due to small sample size. RESULTS Eight studies met inclusion criteria between 2013 and 2021. Most studies were retrospective (87.5%) with median follow-up duration of 12.5 months (range 10-42). There were 440 patients included (range 15-148), mostly men (64%). Mean age was 61 years (range 53-68). Included patients were all symptomatic with L-FEVAR being technically successful in 93.3% of cases. The main indication for aortic arch intervention was aortic dissection. Single fenestrations occurred most frequently (68%), followed by triple (22%) then double fenestrations (9%). Meta-analysis of 8 studies (n = 440) demonstrated an endoleak event rate of 0.06 (95% confidence interval 0.04-0.09, P < 0.001) with no observed statistically significant heterogeneity of effects (Q = 7.91, P = 0.34). The median operative time was 162 min (range 53-252) with median length of stay of 10 days (range 7-17). Primary branch patency was 96.6%. Secondary patency rate was 97%. Pooled complication rates such as endoleak occurred in 4.8%, stroke in 2.0%, spinal cord ischemia in 0.2%, retrograde dissection in 0.9%, and 30-day death in 2.0%. Access complications occurred in 0.4%. Antiplatelet regimen was poorly reported in the study cohort. CONCLUSIONS In situ laser fenestration is a feasible, safe, and effective approach to treat aortic arch disease in patients who are unsuitable for open or custom-made endovascular means. High technical success and excellent short-term branch patency can be achieved. These single-institution series exhibit promising short-term outcomes. In a similar paradigm to investigational device exemptions studies for custom-made and physician modified endografts, these preliminary data make a persuasive argument for larger long-term multi-institutional prospective study of this promising technique.

Whole Body Retrograde Perfusion Combined With Central Aortic Perfusion Strategy in the Repair of Distal Arch Pathology Through a Lateral Thoracotomy. Mayo Clin Proc 2023; 98:432-442. [PMID: 36868750 DOI: 10.1016/j.mayocp.2022.08.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Revised: 03/29/2022] [Accepted: 08/10/2022] [Indexed: 03/05/2023]
Abstract
OBJECTIVE To compare the results of the hypothermic circulatory arrest (HCA) + retrograde whole-body perfusion (RBP) technique with those of deep hypothermic circulatory arrest (DHCA-only) approach. METHODS Limited data are available on cerebral protection techniques when distal arch repairs are performed through a lateral thoracotomy. In 2012, the RBP technique was introduced as adjunct to HCA during open distal arch repair via thoracotomy. We reviewed the results of the HCA + RBP technique compared with those of the DHCA-only approach. From February 2000 to November 2019, 189 patients (median age, 59 [IQR, 46 to 71] years; 30.7% female) underwent open distal arch repair via lateral thoracotomy to treat aortic aneurysms. The DHCA technique was used in 117 patients (62%, median age 53 [IQR, 41 to 60] years), whereas HCA + RBP was used in 72 patients (38%, median age 65 [IQR, 51 to 74] years). In HCA + RBP patients, cardiopulmonary bypass was interrupted when systemic cooling achieved isoelectric electroencephalogram; once the distal arch had been opened, RBP was then initiated via the venous cannula (flow of 700 to 1000 mL/min, central venous pressure <15 to 20 mm Hg). RESULTS The stroke rate was significantly lower in the HCA + RBP group (3%, n=2) compared with the DHCA-only (12%, n=14) (P=.031), despite longer circulatory arrest times in HCA + RBP compared with the DHCA-only (31 [IQR, 25 to 40] minutes vs 22 [IQR, 17 to 30] minutes, respectively; P<.001). Operative mortality for patients undergoing HCA + RBP was 6.7% (n=4), whereas for those undergoing DHCA-only it was 10.4% (n=12) (P=.410). The 1-, 3-, and 5-year age-adjusted survival rates for the DHCA group are 86%, 81%, and 75%, respectively. The 1-, 3-, and 5-year age-adjusted survival rates for the HCA + RBP group are 88%, 88%, and 76%, respectively. CONCLUSION The addition of RBP to HCA in the treatment of distal open arch repair via a lateral thoracotomy is safe and provides excellent neurological protection.

Abstract
AIM The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. Structure: Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

Abstract
PURPOSE In thoracic endovascular aortic repair (TEVAR), the left subclavian artery (LSA) is often occluded. Although most patients tolerate this, some develop ischemic symptoms to the brain or left upper extremity (LUE). A revascularization procedure may be associated with significant complications. The purpose of this review was to assess the incidence of LSA occlusion, resulting ischemic symptoms, and complications related to revascularization operations in trauma patients compared to non-trauma patients. METHODS Studies from 2010 to 2020 were fully reviewed if they discussed incidence of LSA coverage, LUE ischemia, carotid-subclavian bypass, or complications associated with carotid-subclavian bypass. RESULTS Seventeen articles were included in this analysis. A total of 167 patients were identified as trauma cases. Incidence of LSA occlusion in trauma was 91/167 (54%) compared to 281/1446 (19%) in the population exclusive of trauma (p < 0.001). Following LSA occlusion, the rate of LUE claudication/ischemia was 21/56 (38%) for trauma, compared to 12/193 (6%) in non-trauma cases (p < 0.001). The overall complication rate after carotid-subclavian rescue bypass was 29.2% (33/112), with phrenic nerve palsy (24%), recurrent laryngeal nerve palsy (5%), and pseudoaneurysm (1.7%) being the most common. CONCLUSION LSA coverage following TEVAR is common and associated with significant complications, often requiring operative management. The incidence of ischemic complications after occlusion of the LSA is significantly higher in the trauma population. Revascularization procedures to correct the occlusion have a high rate of complications.

Abstract
BACKGROUND Endovascular repair of the thoracic aorta (TEVAR) outcomes have been studied with interest in complications related to left subclavian artery (LSA) coverage in patients with atherosclerotic pathologies; however, specific data on the management of the LSA in a trauma population is lacking. The objective of this study is to evaluate outcomes following TEVAR for traumatic aortic injury based on LSA coverage. METHODS The Vascular Quality Initiative thoracic endovascular aortic repair module (2010-2017) was analyzed. Patients were included if they had a traumatic aortic injury requiring TEVAR. Patients were placed in two groups based on coverage of the left subclavian artery. Patients were propensity score matched and the primary outcomes were cerebrovascular symptoms and spinal cord ischemia. Additional clinical and resource utilization outcomes were analyzed. RESULTS 451 patients were included in the analysis. There were 268 patients in the LSA not covered group and 183 patients in the LSA covered group. The mean aortic injury grade was 2.88±0.056 vs 2.88±0.049 in the covered versus not-covered group (p=0.957). Glasgow coma scale and injury severity score were not different between the groups. There was no difference between groups for cerebrovascular symptoms or spinal cord ischemia, 1.4% vs 2.8% p=0.684 and 0% vs 2.1% p=0.247, after propensity score matching. Significant differences in access site complications and resource utilization were identified between groups. CONCLUSION This is the largest series to evaluate complications based on LSA coverage following TEVAR in trauma patients. Our data demonstrate that coverage of the LSA during TEVAR following blunt trauma is associated with no difference in CNS outcomes. As such, LSA revascularization strategies, while possible, are not directly supported by these data, and should be individualized based on each patient's specific clinical scenario.

Abstract
OBJECTIVES Thoracic endovascular aortic repair (TEVAR) is the standard treatment for acute complicated type B aortic dissection (TBAD). However, long-term results reveal that TEVAR does not achieve a complete aortic remodeling and poses a risk of aneurysmal aortic degeneration. Distal reentry treatment at the abdominal level seems to be necessary to obtain a complete remodeling in TBAD. Moreover, it is necessary to treat the aortoiliac bifurcation in patients with persistent true lumen collapse or limb ischemia. METHODS Between January 2018 and October 2019, 11 patients with acute or sub-acute complicated TBAD or non-A non-B aortic dissection were treated in our institution in an endovascular fashion. We performed the stent-assisted balloon-induced intimal disruption and relamination in aortic dissection repair (STABLISE) technique in all cases, but two cases required complementary treatment of the aortoiliac bifurcation with a bifurcated AFX endograft system for limb ischemia due to true lumen collapse. RESULTS Technical success was obtained in all patients. No procedural complications occurred. No postoperative deaths, stroke, paraplegia, mesenteric, or renal ischemia were observed, and no secondary intervention was necessary. Satisfactory aortic remodeling was obtained after the follow-up periods with a 57.5% mean true lumen expansion. CONCLUSION Our initial experience using the extended STABILISE (e-STABILISE) technique using a bifurcated AFX endograft did not result in any postoperative mortality or complications. Without additional data, this technique should be reserved for specific patients who require revascularization of the aortoiliac bifurcation.

Abstract
Background: Pathologies of the descending thoracic aorta inwardly extended towards the aortic arch actually shorten the proximal landing zone for aortic prosthesis. This, in turn, worsens the feasibility of the aorta for endovascular therapeutic options of those pathologies.
Objective: This work considers the blockage of the left subclavian artery (LSA) through endovascular treatment of the pathologies of the descending aorta as a main work question, which is based on the hypothesis that there is no necessity for primary standard revascularization of the LSA in TEVAR with LSA covering. The researchers have 12 years of experience in treatment of different thoracic aortic lesions. Their experience will also be reviewed in this paper.
Design: Retrospective unicenter cohort study in consecutive patients order to describe the real-world situation of daily clinical practice
Material: All the patients who had undergone endovascular, hybrid, or open operative therapy of variant pathologies of descending aorta were included in this study.
Methods: Various parameters were investigated, including therapeutic procedures such as i) pure endovascular vs. hybrid; ii) year of therapy; iii) symptomatic vs. asymptomatic status of the patients; iv) variant epidemiological factors (age, sex, risk factors, mortality, and follow up); v) overstenting/blocking of the LSA; vi) complications of applied therapies; vii) further operations/interventions to treat such complications; viii) radiologic aortic measurements (such as lumen extensions, false lumen measurements, distance to the supra-aortic and visceral vessels); and ix) multiple other pathological features. Different statistical parameters were also examined. Survival was analysed by the Kaplan–Meier assessment in the group of whole patients vs. the group of over-stented patients. Here the analysis of variance is performed for the independent parameters for the revascularized patients—not the revascularized patients—who had undergone LSA coverage. For statistical approval, U-test was used. The p-value < 0.05 was considered significantly different. The literature review was achieved by a search in PubMed, Google scholar, Research Gate, ScienceDirect, and Cochrane library by using the following terms endovascular, TEVAR, revascularization, stroke, and left-subclavian-artery ischemia. The literature is classified accordingly in relation to the main topic. In fact, the literature undergoes further analysis if it goes with or against our hypothesis.
Results: Overall, 112 patients were enrolled in the study. There was no significant difference comparing the not-revascularized vs. the revascularized group of patients, considering the consequences on cerebrovascular blood circulation (in particular, n=1 case [4.8 %] vs. no case [0 %]; p=1) or the spinal cord ischemia (n=2 [9.5 %] vs. n=1 [7.1 %]; p=1). As the main result, there was no case of manifest left arm ischemia and deaths (mortality, 0). Survival was in both groups as follows: 22 [95% CI, 14.154–29.904] months vs. 43 [95% CI, 33.655–51.921] months with no significant statistical difference (p>0.05) . The only statistically significant risk factor found was renal insufficiency (p, 0.028), but this too is considered a trend by the urgency of revascularization. Postoperatively, pneumonia showed a trend of higher frequency (p=0.058) in the revascularized cases (n=0 in the not-revascularized vs. n=3 [21.4 %] in the revascularized cases). There was no significant difference in the occurance of postoperative neurovascular complications (such as cerebrovascular accidents, spinal cord ischemia, or left arm ischemia) by comparing the groups of not-revascularized and revascularized patients.
Conclusion: The revascularization of the overstented LSA due to TEVAR should be limited to certain indications, including i) the inadequate intracerebral circle of Willis; ii) the predominantly perfused left vertebral artery with inadequate blood perfusion via the right vertebral artery (e.g., by stenosis), iii) anatomic variance such as the left vertebral artery originating directly from the aortic arch (and must be blocked by TEVAR); iv) the need of an adequate left internal thoracic artery for coronary-artery-bypass grafting (CABG); v) the need of patent LSA for the dialysis shunt of the left arm. However, there is no appropriate evidence as yet based on sufficient study results achieved in trials with an advanced design (such as [double-]blind, multicenter randomized study) that appears to be urgently required.

Abstract
Abstract
Background
We performed routine spinal fluid drainage for patients who underwent TEVAR for thoracic aortic pathology together with left subclavian artery coverage, which was needed for achievement of a safe proximal sealing zone. We assessed the occurrence of spinal cord ischemia as well the rate of occurrence of other complications such as stroke, and upper limb ischemia.
Results
This was a case series study done between July 2014 and April 2020, in them all the left subclavian artery was covered to ensure a proximal safe seal zone. Routine spinal fluid drainage was done, keeping the spinal fluid pressure < 10–15 mmHg with catheter in place for 48 h. Data was obtained from twenty-three patients who underwent TEVAR for thoracic aortic dissection (73.91%), thoracic aortic aneurysm (21.74%), or ulcer (4.35%). Planning was based upon multi-slice computed tomographic angiography and covering the left subclavian was mandatory to achieve a proximal sealing zone. Technical success was achieved in 100% of cases. 4.35% of patients had three endograft, 56.52% had two endografts, 39.13% had one endograft. All patients lost their radial pulsations immediately after implantation, 8.70% developed post implantation syndrome(fever) that was managed conservatively, 4.35% developed stroke related to the anterior circulation, 4.35% developed signs of spinal cord ischemia. During the follow up, one patient died within 6 h after the procedure due to extensive myocardial infarction (patient was scheduled for CABG after our procedure). 17.40% developed upper limb symptoms that were tolerable and were managed conservatively.
Conclusion
By adopting routine spinal cord drainage and pressure monitoring, we can consider not to revascularize the left subclavian artery prior to TEVAR if it will be covered.

Abstract
PURPOSE OF REVIEW In the present review, we discuss the role of CT imaging in the management of aortic dissection, with a particular emphasis on endovascular treatment considerations. RECENT FINDINGS Computed tomography imaging is a fundamental tool in the diagnosis and management of acute and chronic aortic dissection. Its diagnostic accuracy and high resolution contribute to and guide operative strategy. Persistent high mortality for patients who develop aortic dissections suggests a need for innovative diagnostic and treatment strategies. In the recent era, considerable advances have been made in computed tomography (CT) image acquisition, processing, and analysis as well as endovascular technologies with expanded roles in the treatment of aortic diseases.

Abstract
BACKGROUND Thoracic endovascular aortic repair (TEVAR) is the gold standard for surgical management of descending thoracic aortic pathology. Depending on the anatomy, TEVAR often requires deployment across the origin of the left subclavian artery (LSA) to obtain a proximal seal, thus potentially compromising perfusion to the left upper extremity (LUE). However, in most patients this is generally well tolerated without revascularization due to collateralization from the left vertebral artery (LVA). CASE PRESENTATION We present a complex 59-year-old Caucasian patient case of TEVAR with a history of prior arch debranching and intraoperative LSA coverage requiring subsequent LSA embolization and emergency take-back for left carotid-subclavian bypass. CONCLUSION The purpose of this case report is to highlight an often overlooked anatomic LVA variant and an atypical, delayed presentation of acute LUE limb ischemia.

Abstract
BACKGROUND Acute type B aortic dissection with origin of the left subclavian artery (LSA) is generally managed with endovascular therapy for acute coverage of the LSA with: 1) no revascularization; 2) revascularization with open methods; or 3) endovascular revascularization. To identify an alternative solution, we critically evaluated a small cohort of patients who had partial coverage of their LSA. METHODS Three thoracic endovascular repairs were performed from January-March 2015. Patients were deemed eligible for endovascular repair after they had failed conservative management. Indications included acute type B dissection with lower extremity ischemia, ruptured dissection, and persistent symptoms of dissection after medical therapy. RESULTS Technical success was achieved in all three patients, and all procedures were performed percutaneously. The mean distance between the ostium of the LSA and the entry point of dissection was 11.1±3.4 mm. Within the 30-day postoperative period, there were no deaths, aortic ruptures, myocardial infarctions, or conversions to open repair. Freedom from re-intervention was noted in all 3 patients. There was no spinal cord ischemia. CONCLUSIONS There is no strong evidence to support the current optimal approach for treatment of the thoracic aorta. Partial coverage of LSA in patients with <2 cm seal zones may be considered as an alternative. However, due to our small sample size, limited follow-up, and lack of comparison cohort, further investigation is necessary.

Meta-analysis of outcomes after intentional coverage of celiac artery in thoracic endovascular aortic repair. J Vasc Surg 2021; 74:1732-1739.e3. [PMID: 33592296 DOI: 10.1016/j.jvs.2021.01.053] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 01/08/2021] [Indexed: 02/08/2023]
Abstract
OBJECTIVE The aim of the present study was to demonstrate the clinical outcomes of intentional coverage of the celiac artery (CA) during thoracic endovascular aneurysm repair (TEVAR). METHODS The MEDLINE, EMBASE, and Cochrane Library databases were searched for studies reporting coverage of CA during TEVAR. The methodologic quality of the included studies was assessed using the Moga score and Newcastle-Ottawa scale. A random effects model was used to pool the estimates. A meta-analysis was performed with investigation of the following outcomes: visceral ischemia, spinal cord ischemia (SCI), stroke, endoleak, reintervention, 30-day mortality, and 1-year mortality. RESULTS A total of 10 studies with 171 patients were included. The summary estimate rate of visceral ischemia events was 4.2% (95% confidence interval [CI], 0.9-8.9%; I2 = 4.1%). The incidence of stroke and SCI was 0.2% (95% CI, 0%-3.4%; I2 = 0%) and 3% (95% CI, 0.3%-7.4%; I2 = 6.1%). The rate of endoleak during the follow-up period was 24.1% (95% CI, 14.3%-35.1%; I2 = 20.0%). The reintervention rate was 13.6% (95% CI, 4.4%-25.7%; I2 = 66.0%). The 30-day and 1-year mortality were 2.9% (95% CI, 0.3%-7.2%; I2 = 6.2%) and 15.2% (95% CI, 7.8%-23.9%; I2 = 0%). CONCLUSIONS Among the patients with complex thoracic aortic pathologies deemed at high risk for open reconstruction, TEVAR with intentional coverage of the CA is a safe and feasible option to extend the distal sealing zone with acceptable rates of visceral ischemia, SCI, type II endoleak from the CA, and 30-day mortality.

Abstract
OBJECTIVE Coverage of the left subclavian artery (LSA) is often required to achieve complete proximal sealing during thoracic endovascular aortic repair. However, whether LSA revascularization should be performed remains controversial. METHODS MEDLINE, Embase, and Cochrane databases were systematically searched to identify all the relevant studies. A random-effects model was applied to pool the effect measures. Dichotomous data were presented using an odds ratio (OR). RESULTS There were 32 studies included for qualitative analysis and 31 studies for quantitative analysis. We found that patients who underwent LSA revascularization had a significantly decreased risk of spinal cord ischemia (OR, 0.62; 95% confidence interval [CI], 0.41-0.92; P = .02; I2 = 0%), cerebrovascular accident (OR, 0.63; 95% CI, 0.42-0.95; P = .03; I2 = 22%), and left upper extremity ischemia (OR, 0.18; 95% CI, 0.09-0.36; P < .00001; I2 = 0%). However, no significant differences were found in the risk of paraplegia (OR, 0.91; 95% CI, 0.55-1.51; P = .71; I2 = 0%) and 30-day mortality (OR, 0.89; 95% CI, 0.59-1.36; P = .60; I2 = 21%) between the groups of patients with and without LSA revascularization. CONCLUSIONS Revascularization of the LSA is associated with decreased risks of cerebrovascular accident, spinal cord ischemia, and left upper limb ischemia in thoracic endovascular aortic repair with LSA coverage at the cost of higher local complications, such as possible vocal cord paresis.

Abstract
OBJECTIVES Endovascular repair has been proposed as an alternative to classical surgical repair for the management of blunt traumatic thoracic aortic injury. However, the long-term outcomes of endovascular repair and the risks of left subclavian coverage remain unclear. METHODS From April 2001 to August 2018, 33 patients with blunt traumatic thoracic aortic injury underwent endovascular repair in our institution. A follow-up computed tomography and a clinical examination were performed before discharge and at 1 month, and yearly or every 2 years thereafter. RESULTS The mean age was 45 ± 19 years. The technical success rate was 100%. Complete coverage of the left subclavian artery (LSCA) was performed in 20 patients (60.6%). Among 20 patients with coverage of the LSCA, revascularization was performed in 1 patient. No in-hospital deaths occurred. The clinical follow-up rate was 97%, with a mean period of 7 years and a maximum of 18 years. The survival rates were 100% at 1 year, 95% at 5 years and 88.7% at 10 years after the event. Among the 5 patients (20%) who developed neurological complications, 1 who had undergone implantation of a 200-mm long stent graft and LSCA coverage without revascularization developed paraplegia during the long-term follow-up. CONCLUSIONS This study demonstrates that the endovascular treatment of blunt traumatic thoracic aortic injury is a safe and effective therapeutic method over a long-term follow-up period. LSCA coverage and long stent graft placement might be indications for revascularization to prevent spinal cord injury.

Abstract
Objectives Investigate the impact of left subclavian artery coverage without revascularization on spinal cord ischemia development in patients undergoing thoracic endovascular aortic repair. Methods The Vascular Quality Initiative thoracic endovascular aortic repair module (April 2011–July 2014) was analyzed. Patients undergoing left subclavian artery coverage were divided into two groups according to revascularization status. The association between left subclavian artery revascularization with the primary outcome of spinal cord ischemia and the secondary outcome of stroke was assessed with multivariable analysis adjusting for between-group baseline differences. Results The left subclavian artery was covered in 508 (24.6%) of the 2063 thoracic endovascular aortic repairs performed. Among patients with left subclavian artery coverage, 58.9% underwent revascularization. Spinal cord ischemia incidence was 12.1% in the group without revascularization compared to 8.5% in the group undergoing left subclavian artery revascularization (odds ratio (95%CI): 1.48(0.82–2.68), P = 0.189). Multivariable analysis adjustment identified an independent association between left subclavian artery coverage without revascularization and the incidence of spinal cord ischemia (adjusted odds ratio (95%CI): 2.29(1.03–5.14), P = 0.043). Although the incidence of stroke was also higher for the group with a covered and nonrevascularized left subclavian artery (12.1% versus 8.5%), this difference was not statistically significant after multivariable analysis (adjusted odds ratio (95%CI): 1.55(0.74–3.26), P = 0.244). Conclusion For patients undergoing left subclavian artery coverage during thoracic endovascular aortic repair, the addition of a revascularization procedure was associated with a significantly lower incidence of spinal cord ischemia.

Abstract
PURPOSE Thoracic endovascular aortic aneurysm repair (TEVAR) has become a mainstay of therapy for aneurysms and other disorders of the thoracic aorta. The purpose of this narrative review article is to summarize the current literature on the risk factors for and pathophysiology of spinal cord injury (SCI) following TEVAR, and to discuss various intraoperative monitoring and treatment strategies. SOURCE The articles considered in this review were identified through PubMed using the following search terms: thoracic aortic aneurysm, TEVAR, paralysis+TEVAR, risk factors+TEVAR, spinal cord ischemia+TEVAR, neuromonitoring+thoracic aortic aneurysm, spinal drain, cerebrospinal fluid drainage, treatment of spinal cord ischemia. PRINCIPAL FINDINGS Spinal cord injury continues to be a challenging complication after TEVAR. Its incidence after TEVAR is not significantly reduced when compared with open thoracoabdominal aortic aneurysm repair. Nevertheless, compared with open procedures, delayed paralysis/paresis is the predominant presentation of SCI after TEVAR. The pathophysiology of SCI is complex and not fully understood, though the evolving concept of the importance of the spinal cord's collateral blood supply network and its imbalance after TEVAR is emerging as a leading factor in the development of SCI. Cerebrospinal fluid drainage, optimal blood pressure management, and newer surgical techniques are important components of the most up-to-date strategies for spinal cord protection. CONCLUSION Further experimental and clinical research is needed to aid in the discovery of novel neuroprotective strategies for the protection and treatment of SCI following TEVAR.

Abstract
BACKGROUND The application of thoracic endovascular aortic repair (TEVAR), a minimally invasive operation, in the aortic arch has been a challenge of cardiovascular surgery in recent years. This study aimed to investigate management of the vertebral artery with coverage of the left subclavian artery (LSA) during TEVAR. METHODS From January 2007 to September 2014 in the Department of Cardiothoracic Surgery at Wuhan General Hospital of Guangzhou Military Region, 160 patients underwent LSA closure or partial coverage during TEVAR of an aortic lesion near the LSA. The vertebral artery treatment, the reason for the surgical approach selection, and the prognosis were analyzed. RESULTS In 94 patients with partial LSA coverage during TEVAR, no treatment was provided for the vertebral arteries, revealing blood flow of the left vertebral artery forward into the skull after surgery. For 66 patients with full LSA coverage (closure) during TEVAR, right carotid artery-left common carotid artery bypass surgery was performed before TEVAR in ten patients, without any treatment for the vertebral artery, showing reverse blood flow of the left vertebral artery after surgery. Left common carotid artery-LSA bypass surgery was performed before TEVAR in four patients; right common carotid artery-left common carotid artery-LSA bypass surgery was performed before TEVAR in three cases, and 6 out of these 7 patients underwent proximal LSA ligation, showing no obvious blood flow in the left vertebral artery. The closure of the LSA aortic arch opening using an occluder was performed in one patient, preserving the forward blood flow in the left vertebral artery. Among the 160 patients in this study, postoperative recurrent laryngeal nerve injury occurred in one patient after right common carotid artery-left common carotid artery-LSA bypass surgery, and the remaining 159 patients had no significant severe complications or death within 1 postoperative month. CONCLUSIONS Appropriate management of the aortic arch branch vessels may expand the application of TEVAR to the aortic arch and reduce complications, especially for high-risk patients who have a difficult time tolerating thoracotomy.

Methods: A multicenter registry in the Netherlands captured data on 30 patients (mean age 68 years; 17 men) with thoracic aortic pathology and a short (<20 mm) proximal or distal landing zone who received a custom-made scalloped stent-graft between January 2013 and February 2016. Patients were treated for saccular (n=13) aneurysms, fusiform (n=9) aneurysms, pseudoaneurysms (n=4), or chronic type B dissections (n=4). The scallop was used to preserve flow in the left subclavian artery (LSA) (n=17), left common carotid artery (n=5), innominate artery (n=1), and celiac trunk (n=7). In 7 (23%) patients, the scallop also included the adjacent artery. Results: Technical success was achieved in 28 (93%) patients. In 1 patient, a minor type Ia endoleak was observed intraoperatively, which was no longer visible on computed tomography angiography at 3 months. In another patient, the LSA was unintentionally obstructed due to migration of the stent-graft on deployment. Concomitant carotid-carotid or carotid-subclavian bypass was performed in 4 patients. There was no retrograde type A dissection or conversion to open surgery. In-hospital mortality was 3%, and the perioperative ischemic stroke rate was 3%. At a mean follow-up of 9.7 months (range <1 to 31), 29 of 30 target vessels were patent. Conclusion: The scalloped stent-graft appears to be a safe and relatively simple alternative for the treatment of thoracic aortic lesions with short landing zones. Larger patient series and long-term follow-up are required to confirm these early results.

Abstract
Purpose: To evaluate risk factors for early (<30 days) type I endoleak following thoracic endovascular aortic repair (TEVAR). Methods: A retrospective study was conducted of 439 consecutive patients (mean age 74.0±10.0 years; 333 men) who underwent TEVAR at a single center between June 2006 and June 2013. Pathologies included 237 aortic arch aneurysms and 202 descending thoracic aortic aneurysms (dTAA). Maximum TAA diameter was 63.6±13.7 mm. Among the distal aortic arch aneurysms, 124 required coverage of the left subclavian artery (LSA), while the remaining 113 arch aneurysms had debranching (n=40), the chimney technique (n=52), and a branched stent-graft (n=13). Eight patients with dilatation of the ascending aorta underwent arch replacement with elephant trunk prior to TEVAR. Predictive factors for type I endoleak were explored in univariate analysis and examined for each outcome using logistic regression models; results are given as the odds ratio (OR) and 95% confidence interval (CI). Results: Among 439 TEVAR cases, 37 (8.4%) had type I endoleaks on imaging at 1 month; 31 were in the 237 arch cases (13.1%). Endoleak investigation by site indicated a low incidence (3.0%) for dTAAs and markedly low (1.4%) in zone 4. Significantly more endoleaks were observed in zones 0–2 than in zone 4 (p<0.001). On univariate analysis, significant associations were found between endoleak and LSA coverage (OR 5.8, 95% CI 2.4 to 14.4, p<0.001), operative time ≥240 minutes (OR 3.7, 95% CI 1.5 to 6.2, p=0.002), and ≥270 mL of contrast (OR 2.8, 95% CI 1.4 to 5.8, p=0.004). Among the aortic branch reconstruction procedures, the chimney technique was the only maneuver associated with a significant risk of endoleak (OR 5.3, 95% CI 2.3 to 11.2, p<0.001). Arch state was not correlated with endoleaks, but ≥38-mm proximal neck diameter (OR 3.6, 95% CI 1.2 to 10.8, p=0.023), stent-graft diameter ≥40 mm (OR 9.9, 95% CI 1.4 to 30.5, p=0.015), and excessively oversized (≥14%) stent-grafts (OR 3.5, 95% CI 1.2 to 10.3, p=0.020) were; the proximal neck length was not correlated with endoleaks if a proximal neck length >10 mm can be secured. Conclusion: Risks for early type I endoleaks after TEVAR for aneurysm were landing zone 0–2, LSA coverage, large proximal neck and stent-graft diameters, excessive oversizing, and the use of the chimney technique.

Abstract
BACKGROUND Traumatic thoracic aortic dissection is uncommon in clinical practice; however, it is associated with high morbidity and mortality. Thoracic aortic dissection is usually caused by sudden deceleration resulting from a traffic accident or fall. Aortic injury after blunt trauma is a critical condition. This study reported the outcomes of endovascular repair of acute traumatic aortic dissection in patients at a district general hospital. METHODS In this study, we retrospectively reviewed the clinical data of eight patients with acute traumatic aortic dissection after a blunt trauma who had undergone thoracic endovascular aortic repair (TEVAR) between January 2012 and December 2015 at a district general hospital in Taiwan. RESULTS The median age of the patients was 49±22 years (range, 20-77 years), and 6 of the 8 (75%) patients were men. Five patients were involved in traffic accidents, and 3 patients had fallen from heights. The injury severity score (ISS) of the patients ranged from 17 to 66. In all patients, the aortic injury was located near the origin of the left subclavian artery (LSA). Four patients had seal ostium of subclavian artery, left. None of the patients developed paraplegia or lower extremity ischemia. Moreover, all patients had concomitant injuries, and no patients died postoperatively. CONCLUSIONS Endovascular repair is a rapid and minimally invasive therapy for patients with traumatic aortic injury and is associated with favorable technical results.

Abstract
Background Most blunt aortic injuries occur in the proximal proximal descending aorta causing acute transection of this vessel. Generally, surgical repair of the ruptured segment of aorta is associated with high rates of morbidity and mortality and in this view endovascular treatment seems to be a valid and safer alternative. Aim of this article is to review our experience with endovascular approach for the treatment of acute traumatic rupture of descending thoracic aorta. Methods From April 2002 to November 2014, 11 patients (9 males and 2 females) were referred to our Department with a diagnosis of acute transection of thoracic aorta. Following preoperative Computed Tomography (CT) evaluation, thoracic endovascular aortic repair (TEVAR) with left subclavian artery coverage was performed. Follow-up consisted clinical and instrumental (CT, Duplex ultrasound) controls at discharge, 1, 3 and 6 months and yearly thereafter. Results At 12-year follow up, the overall survival for the entire patients cohort was 100 %, no major or minor neurological complications and no episode of left arm claudication occurred. Cardiovascular, respiratory and bleeding complications, in the early period, was represented by minor, non fatal events. No stent graft failure, collapse, leak or distal migration were detected at CT scan during the entire follow up period. Conclusions According to our experience, despite the small number of patient population, TEVAR procedure with with left subclavian artery coverage, performed in emergency settings, seems to provide excellent long term results. Trials registration The protocol was registered at a public trials registry, www.clinicaltrials.gov (trial identifier NCT02376998).

Abstract
Several authors have described anatomic variations of the aortic arch in 13% to 20% of the patients who do not have aortic disease. However, few studies have evaluated these patterns in the thoracic aortic dissection (TAD). In the authors' knowledge, this is the first survey that specifically investigates the frequency of these variations in a broad, nonselected group of Chinese patients with aortic dissection. Furthermore, it compares this group with a group of patients without aortic disease.The objective of this study was to define the variation frequency of the aortic arch branches pattern using the tomographic studies of 525 Chinese patients with a diagnosis of TAD. The Stanford classification was used to set the site of the initial tear of the dissection. In addition, we performed an epidemiological analysis of the aortic arch anatomic variations in TAD, and its possible implications for surgical or endovascular treatment. The general hypothesis proposal asserted that Chinese patients with dissection of the aorta have a similar incidence of variations of the aortic arch to the patients without aortic disease.A retrospective study of cases and controls was carried out using the tomographic studies (CT) of all patients admitted to the First Affiliated Hospital of Zhengzhou University, located at Henan-China, with a confirmed diagnosis of aortic dissection from January 2012 until December 2014. The group of cases consisted of 525 patients: 374 men and 151 women, with a mean age of 52.27 years (range, 20-89). The average age of the patients with Stanford A and B aortic dissection was 49.46 and 53.67, respectively. The control group consisted of 525 unselected patients without TAD who underwent a CT scan of the chest due to other indications. This group consisted of 286 men and 239 women, with a mean age of 53.60 years (range, 18-89). All the patients with aneurysm or dissection were excluded from the control group. We performed a statistical analysis of demographic data.The study found 7 different patterns of the aortic arch on both groups of cases and controls. Within the 525 patients with TAD were observed 85 (16.19%) anatomical variations, while the control group showed 112 variations (21.33%); P = 0.033. The most common anatomical variant was the bovine arch, found in 62 (11.80%) cases of TAD compared with 77 (14.66%) in the control group; P = 0.172. Anatomical variations were observed in 14.32% of the patients with Stanford A dissection and 17.09% of the patients with Stanford B dissection; P = 0.425. Patients with Stanford A dissection showed the pattern of bovine arch in 23 (13.21%) of 174 cases. In contrast, the patients with Stanford B dissection showed it in 39 (11.11%) of 351 cases; P = 0.481. The anatomical variant defined as vertebral artery of direct origin of the aortic arch was more frequent in the patients with Stanford B dissection (5.12%). The patients with Stanford A dissection presented this pattern in 1.14% of the cases; P = 0.025. This study observed an increased frequency of aortic dissection in the subgroup from 41 to 60 years old. In the subgroup from 41 to 60 years old without TAD, a greater frequency of anatomical variations were found than in the patients with TAD (20.81% vs 14.23%; P = 0.050). The same fashion was seen in patients older than 80 years (27.27% vs 0%; P = 0.030). The anatomical variations of the aortic arch with TAD occurred in 14.97% of the male patients and 19.20% of the female patients compared to 21.67% to 20.92% in the control group; P = 0.026 and P = 0.681, respectively.The aortic arch variations were found less frequently in the TAD group than in the control group in the present Chinese series. The bovine arch was considered the variant pattern of the major frequency in the patients with TAD and the control group. The anatomical variant of 4 branches, defined as vertebral artery of direct origin of the aortic arch, was more frequent in patients with Stanford B aortic dissection than in the patients with Stanford A.This finding might show an association between the geometry of the aortic arch and the site of onset of first intimal tear of dissection.

Abstract
BACKGROUND Practice guidelines for management of the left subclavian artery (LSA) during thoracic endovascular aortic repair (TEVAR) are based on low-quality evidence, and there is limited literature that addresses optimal revascularization techniques. The purpose of this study was to compare outcomes of LSA coverage during TEVAR and revascularization techniques. STUDY DESIGN We performed a single-center retrospective cohort study from 2001 to 2013. Patients were categorized by LSA revascularization and by revascularization technique, carotid-subclavian bypass (CSB), or subclavian-carotid transposition (SCT). Thirty-day and mid-term stroke, spinal cord ischemia, vocal cord paralysis, upper extremity ischemia, primary patency of revascularization, and mortality were compared. RESULTS Eighty patients underwent TEVAR with LSA coverage, 25% (n = 20) were unrevascularized and the remaining patients underwent CSB (n = 22 [27.5%]) or SCT (n = 38 [47.5%]). Mean follow-up time was 24.9 months. Comparisons between unrevascularized and revascularized patients were significant for a higher rate of 30-day stroke (25% vs 2%; p = 0.003) and upper extremity ischemia (15% vs 0%; p = 0.014). However, there was no difference in 30-day or mid-term rates of spinal cord ischemia, vocal cord paralysis, or mortality. There were no statistically significant differences in 30-day or midterm outcomes for CSB vs SCT. Primary patency of revascularizations was 100%. Survival analysis comparing unrevascularized vs revascularized LSA was statistically significant for freedom from stroke and upper extremity ischemia (p = 0.02 and p = 0.003, respectively). After adjustment for advanced age, urgency, and coronary artery disease, LSA revascularization was associated with lower rates of perioperative adverse events (odds ratio = 0.23; p = 0.034). CONCLUSIONS During TEVAR, LSA coverage without revascularization is associated with an increased risk of stroke and upper extremity ischemia. When LSA coverage is required during TEVAR, CSB and SCT are equally acceptable options.

Abstract
Background Thoracic endovascular aortic repair (TEVAR) is becoming increasingly popular due to reduced perioperative morbidity and mortality compared with open surgical repair. However, complications can occur when the left subclavian artery is involved. When performing TEVAR with left carotid-subclavian artery bypass the stent graft will extend to the left common carotid artery. We herein present the case of a patient with a type B aortic dissection with an acute intramural hematoma. Chylothorax was noted after TEVAR with left carotid-subclavian artery bypass. Case report A 66-year-old female with descending aortic dissection that was treated conservatively developed the sudden onset of back pain. Aortic computed tomography (CT) showed a type B intramural aortic dissection. TEVAR with left carotid-subclavian artery bypass was performed. Left chylothorax was noted after surgery with drainage of up to 1000 mL per day. Conservative management was ineffective. Thoracoscopic ligation of the thoracic duct was performed with resolution of the chyle leakage. Conclusion Chylothorax can occur after TEVAR with carotid-subclavian artery bypass and likely results from thoracic duct injury. When conservative treatments fail, ligation of the thoracic duct cephalad to aortic hiatus can resolve the chyle leakage.

Abstract
BACKGROUND Thoracic endovascular aortic repair (TEVAR) is widely used for treatment of traumatic aortic injury (TAI). Stent graft coverage of the left subclavian artery (LSA) may be required in up to 40% of patients. We evaluated the long-term effects of intentional LSA coverage (LSAC) on symptoms and return to normal activity in TAI patients compared with a similarly treated group whose LSA was uncovered (LSAU). METHODS Patients were identified from a prospective institutional trauma registry between September 2005 and July 2012. TAI was confirmed using computed tomography angiography. The electronic medical records, angiograms, and computed tomography angiograms were reviewed in a retrospective fashion. In-person or telephone interviews were conducted using the SF-12v2 (Quality Metrics, Lincoln, RI) to assess quality of life. An additional questionnaire was used to assess specific LSA symptoms and the ability to return to normal activities. Data were analyzed by Spearman rank correlation and multiple linear and logistic regression analysis with appropriate transformations using SAS software (SAS Institute, Cary, NC). RESULTS During the study period, 82 patients (57 men; mean age 40.5 ± 20 years, mean Injury Severity Score, 34 ± 10.0) underwent TEVAR for treatment of TAI. Among them, LSAC was used in 32 (39.5%) and LSAU in 50. A group of the LSAU patients (n = 22) served as matched controls in the analysis. We found no statistically significant difference in SF-12v2 physical health scores (ρ = -0.08; P = .62) between LSAC and LSAU patients. LSAC patients had slightly better mental health scores (ρ = 0.62; P = .037) than LSAU patients. LSAC patients did not have an increased likelihood of experiencing pain (ρ = -0.0056; P = .97), numbness (ρ = -0.12; P = .45), paresthesia (ρ = -0.11; P = .48), fatigue (ρ = -0.066; P = .69), or cramping (ρ = -0.12; P = .45). We found no difference between groups in the ability to return to activities. The mean follow-up time was 3.35 years. Six LSAC patients (19%) died during the follow-up period of unrelated causes. CONCLUSIONS Intentional LSAC during TEVAR for TAI appears safe, without compromising mental or physical health outcomes. Furthermore, LSAC does not increase the long-term risk of upper extremity symptoms or impairment of normal activities.

Abstract
Background The management of the left subclavian artery when coverage is necessary during thoracic aorta endografting remains a matter of debate. Materials and methods A retrospective analysis of a single-centre experience with thoracic endovascular aorta repair (TEVAR) was performed. Between April 2004 and October 2012, 125 cases of TEVAR were performed. The analysis focused on patients who required coverage of the left subclavian artery (LSA). We analysed mortality and morbidity with special attention to the rates of cerebrovascular accidents (CVAs) and spinal cord ischaemia (SCI) in the early and midterm. Results Of the 125 patients, 53 (42 %, group A) required an intentional coverage of the LSA to obtain an adequate proximal seal for the endograft; the remaining patients constituted group B. None of the patients in group A had protective LSA revascularisation prior to TEVAR. The primary technical success rate was 79.2 vs. 90.3 % (group A vs. group B, p = 0.08), and the primary clinical success rate was 77.4 vs. 82 % (group A vs. group B, p = 0.53). The 30-day mortality rate was 11.3 vs. 11.1 % (group A vs. group B, p = 0.97). The 30-day morbidity was 7.5 vs. 13.9 % (group A vs. group B, p = 0.4). CVA occurred in 1.9 % of group A patients, compared to 1.4 % of patients from group B (p = 0.82). The SCI incidence rate was 0 vs. 1.4 % (p = 0.39). The mean follow-up of group A was 24.1 months (range 2–64.6 months, SD = 19). Additionally, the 1-year estimated survival was 85.5 %, and the 3-year estimated survival was 78 %. There were no midterm CVAs; one event of SCI occurred in the seventh post-operative month in group A. Conclusion Our analysis, although retrospective and based on one institution experience, shows a realistic population of TEVAR patients. We prove that TEVAR with coverage of LSA origin can be accomplished with minimal neurological morbidity in this patient population. The study shows that LSA revascularisation is not mandatory before endograft deployment, especially in emergency settings. We also prove that although zone 2 TEVAR extends the proximal landing zone, it does not prevent type IA endoleaks from appearing. A multicentre randomised control trial with higher number of patients is necessary for proper, robust conclusion to be established.

Abstract
BACKGROUND The objective of this study was to report on the incidence of left arm ischemia, left arm function, and quality of life after thoracic endovascular aortic repair (TEVAR) by stent grafting with and without coverage of the left subclavian artery (LSA). METHODS All patients who underwent TEVAR since 1996 in our institution were included. Basic demographic parameters, underlying disease, details of TEVAR, long-term left arm function (Disabilities of the Arm, Shoulder, and Hand [DASH] questionnaire), and quality of life (12-Item Short Form Health Survey) were analyzed. End points were left arm ischemia, need for LSA revascularization (before or after TEVAR), long-term functional impairment, and quality of life. RESULTS A total of 138 patients underwent TEVAR for degenerative aneurysm (n = 64), traumatic aortic injury (TAI; n = 38), or Stanford type B dissection (n = 36). Seventy-three patients (52.9%) had LSA coverage, which led to partial or complete LSA occlusion in 49 (35.5%). Selectively, nine patients (6.5%) had primary LSA revascularization. After TEVAR, left arm ischemia was observed in only one patient, who consecutively needed a left carotid to subclavian bypass. During a mean follow-up period of 4.1 ± 3.7 years, no additional patient needed secondary LSA revascularization. In comparing patients with occluded vs patent LSA, the Physical Component Summary (PCS) and Mental Component Summary (MCS) health scores (12-Item Short Form Health Survey) as well as DASH scores were similar. However, subgroup analysis showed better PCS scores for TAI patients with patent LSA, whereas MCS and DASH scores were similar in TAI patients, and scores were indifferent within thoracic aortic aneurysm and Stanford type B dissection subgroups. In comparing different subgroups, TAI patients had significantly better PCS, MCS, and DASH scores. CONCLUSIONS TEVAR is associated with a low risk of peri-interventional left arm ischemia. During long-term follow-up, secondary LSA revascularization is uncommon. Coverage of the LSA has no impact on left arm function and quality of life, probably with the exception of physical health scores in patients with TAI.
