Abstract
Background Because thoracic endovascular aortic repair (TEVAR) has become the standard of care for complicated type B aortic dissection (TBAD) and descending thoracic aortic (DTA) aneurysm, it is important to understand outcomes and use of TEVAR across thoracic aortic pathologies. Methods and Results This was an observational study of patients with TBAD or DTA undergoing TEVAR from 2010 to 2018, using the Nationwide Readmissions Database. In-hospital mortality, postoperative complications, admission costs, and 30- and 90-day readmissions were compared between the groups. Mixed model logistic regression was used to identify variables associated with mortality. An estimated total of 12 824 patients underwent TEVAR nationally, of which 6043 had an indication of TBAD and 6781 of DTA. Patients with aneurysms were more likely to be older, women, have cardiovascular disease, and have chronic pulmonary disease compared with patients with TBAD. Weighted in-hospital mortality was higher for TBAD (8% [1054/12 711] versus 3% [433/14 407], P<0.001), compared with DTA, as were all postoperative complications. Patients with TBAD had a higher cost of care during their index admission (57.3 versus 38.8 × $1000, P<0.001), compared with DTA. The 30-day and 90-day weighted readmissions were more frequent for the TBAD group compared with DTA (20% [1867/12 711] and 30% [2924/12 711] versus 15% [1603/14 407] and 25% [2695/14 407], respectively, P<0.001). On multivariable adjustment, TBAD was independently associated with mortality (odds ratio, 2.06 [95% CI, 1.68-2.52]; P<0.001). Conclusions After TEVAR, patients who presented with TBAD had higher rates of postoperative complications, in-hospital mortality, and cost compared with DTA. The incidence of early readmission was substantial for patients undergoing TEVAR, faring worse for those undergoing TEVAR for TBAD as compared with DTA.

Ann Vasc Surg 2022; 87:205-212. [PMID: 35835381 PMCID: PMC9901212 DOI: 10.1016/j.avsg.2022.06.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 06/20/2022] [Accepted: 06/23/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Ischemic stroke is a devastating complication of thoracic endovascular aortic repair (TEVAR). This risk may be higher in more proximal aneurysms that require arch manipulation. The purpose of this study is to (1) describe 30-day stroke and death rates in patients undergoing TEVAR, (2) compare stroke rates in patients undergoing TEVAR for arch versus descending aneurysm pathology, and (3) identify predictive factors associated with stroke after TEVAR. METHODS The Vascular Quality Initiative registry was queried (2015-2021) for TEVAR procedures performed for degenerative aneurysms. Our primary outcomes were any stroke or death at 30 days. Patient-, procedure-, and hospital-level predictors of stroke were assessed using multivariable Poisson regression. RESULTS Among 3,072 patients with degenerative aneurysms (197 [6.4%] arch versus 2,875 [93.6%] descending) treated with elective TEVAR, the median age was 73 years (interquartile range 67-79) and 54.8% were male. Within the arch aneurysm group, there were 27.4% zone 0, 22.8% zone 1, and 49.8% zone 2 interventions. Overall 30-day stroke and death rates were 3.2% and 3.8%. The distribution of stroke events was bilateral (52.9%), left carotid (20.7%), left vertebrobasilar (11.5%), right carotid (9.2%), and right vertebrobasilar (5.7%). Although mortality was similar between groups, the rate of ischemic stroke was higher for patients undergoing TEVAR for arch aneurysm versus descending aneurysms (7.1% arch versus 2.9% descending, P = 0.001). Factors that were associated with ischemic stroke after TEVAR included age (>79 years, relative risk [RR] 1.79, 95% confidence interval [CI] 1.08-2.98 vs. <79 years), dependent functional status (RR 1.73, 95% CI 1.07-2.78), procedural time (RR 1.25, 95% CI 1.15-1.36), and endovascular intervention for supra-aortic trunk revascularization (RR 2.66, 95% CI 1.06-6.70 versus no intervention). CONCLUSIONS Ischemic stroke risk after TEVAR was increased for arch aneurysms compared to descending aneurysms. More proximal zone coverage and endovascular interventions on the supra-aortic trunks were associated with increasing risk for stroke. Adequate preparation for stroke prevention is necessary prior to TEVAR with supra-aortic trunk revascularization.

Abstract
INTRODUCTION Thoracic endovascular aortic repair (TEVAR) became the standard of care for treating Type B aortic dissections and descending thoracic aortic aneurysms. We aimed to describe the racial/ethnic differences in TEVAR utilization and outcomes. METHODS The National Inpatient Sample was reviewed for all TEVARs performed between 2010 and 2017 for Type B aortic dissection and descending thoracic aortic aneurysm (DTAA). We compared groups stratifying by their racial/ethnicity background in White, Black, Hispanic, and others. Mixed-effects logistic regression was performed to assess the relationship between race/ethnicity and the primary outcome, in-hospital mortality. RESULTS A total of 25,260 admissions for TEVAR during 2010-2017 were identified. Of those, 52.74% (n = 13,322) were performed for aneurysm and 47.2% (n = 11,938) were performed for Type B dissection. 68.1% were White, 19.6% were Black, 5.7% Hispanic, and 6.5% were classified as others. White patients were the oldest (median age 71 years; p < .001), with TEVAR being performed electively more often for aortic aneurysm (58.8% vs. 34% vs. 48.3% vs. 48.2%; p < .001). In contrast, TEVAR was more likely urgent or emergent for Type B dissection in Black patients (65.6% vs. 41.1% vs. 51.6% vs. 51.7%; p < .001). Finally, the Black population showed a relative increase in the incidence rate of TEVAR over time. The adjusted multivariable model showed that race/ethnicity was not associated with in-hospital mortality. CONCLUSION Although there is a differential distribution of thoracic indication and comorbidities between race/ethnicity in TEVAR, racial disparities do not appear to be associated with in-hospital mortality after adjusting for covariates.

J Vasc Surg 2021; 75:833-841.e1. [PMID: 34506896 DOI: 10.1016/j.jvs.2021.08.056] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Accepted: 08/05/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVE Thoracic endovascular aortic repair (TEVAR) for descending thoracic aortic aneurysm (DTAA) is associated with high perioperative survival, although mortality is a possible outcome. However, no risk score has been developed to predict mortality after TEVAR for intact DTAA to aid in risk discussion and preoperative patient selection. Our objective was to use a multi-institutional database to develop a 30-day mortality risk calculator for TEVAR after DTAA repair. METHODS The Vascular Quality Initiative database was queried for patients treated with TEVAR for intact DTAA between August 2014 and August 2020. Univariable and multivariable analyses aided in developing a 30-day mortality risk score. Internal validation was done with K-fold cross-validation and calibration curve analysis. RESULTS Of 2141 patients included in the analysis, 90 (4.2%) died within 30 days after the procedure. Clinically relevant variables identified to be independently associated with 30-day mortality and therefore used to derive the predictive model included age 75 years or greater (odds ratio [OR], 2.27; 95% confidence interval [CI], 1.50-3.44; P < .001), coronary artery disease (OR, 1.60; 95% CI, 1.03-2.47; P = .036), American Society of Anesthesiologists class IV/V (OR, 2.39; 95% CI, 1.39-4.10; P = .002), urgent vs elective procedure (OR, 3.47; 95% CI, 1.90-6.33; P < .001), emergent vs elective procedure (OR, 5.27; 95% CI, 2.36-11.75; P < .001), prior carotid revascularization (OR, 3.24; 95% CI, 1.64-6.39; P = .001), and proximal landing zone <3 (OR, 2.51; 95% CI, 1.65-3.81; P < .001). The model showed an area under the receiver operating characteristic curve of 0.75. Internal validation demonstrated a bias-corrected area under the receiver operating characteristic curve of 0.73 (95% CI, 0.66-0.79) and a calibration slope of 1.00 with a corresponding intercept of 0.00. CONCLUSIONS This study provides a novel clinically relevant risk prediction model to estimate 30-day mortality risk after TEVAR for DTAA. The TEVAR Mortality Risk Calculator provides useful prognostic information to guide patient selection and facilitate preoperative discussions and shared decision making. An easily accessible online version of the TEVAR Mortality Risk Score is available to facilitate ease of use.

A Systematic Review. Ann Vasc Surg 2021; 75:29-44. [PMID: 33831530 DOI: 10.1016/j.avsg.2021.03.024] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Revised: 03/01/2021] [Accepted: 03/11/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVE Branched and fenestrated endografts (fEVAR/bEVAR) are complex techniques used to treat thoracic aorta pathologies involving the aortic arch. This systematic review aims to determine all the reported results regarding these techniques in the aortic arch, in order to describe their clinical outcomes. METHODS A systematic review of the literature was performed, considering all articles published until October 2019. PubMed, Cochrane database resources were used. The protocol of the study was previously registered in the Prospero database (CRD42020147037). Primary exclusion criteria included opinion articles, merely technique descriptions, articles without the follow-up of at least 1 month, studies conducted on animals, mixed treatments, and ongoing trials without published data. Included variables were study design, aortic pathology, type of endovascular technique (fEVAR/bEVAR), endograft manufacturing, number of fenestrations/branches and type of bridge stents. Technical success, complications during surgery and follow-up were also described. RESULTS From a total of 164 articles, 29 (28 retrospective, 1 prospective) were analyzed with a total of 693 cases (341 fEVAR and 352 bEVAR). The most common indications for repair were aneurysm (54.8%) and dissection (40%). Only fEVAR and bEVAR were considered, but different endograft materials and techniques were used and, therefore, reported upon in the current review. Zenith Alpha Thoracic Endovascular Graft was the most representative (24% of cases). Custom made, off-the-shelf, physician modified and in situ fenestrated endografts were also used in 39%, 22.4%, 18.6% and 18.9% of cases, respectively. Bridge stents were implanted in the 50.5% of cases. Technical success rate was 96%. The main intraoperative complication was the endoleak (5.2%) followed by stroke (4.8%). The in-hospital mortality was 2.5%. The mean follow-up was 18.5 months. The mortality related to the main operation during follow-up was 3.2% and not directly related to the main operation was 11.3%. During the follow-up, 92 cases (13.3%) in total had to undergo through a reintervention, 46.7% with endovascular repair and 26.1% with open surgical repair (the rest were not specified). CONCLUSION published experience with bEVAR and fEVAR in the aortic arch showed acceptable short-term effectiveness and safety. More well-conducted prospective clinical studies with long term follow-up, combined with comparative meta-analysis, are needed to elucidate the real benefit of those endovascular techniques in the aortic arch pathology.

Abstract
BACKGROUND Adequate seal for thoracic endovascular aortic repair (TEVAR) commonly requires landing in zone 2, but can prove to be challenging due to the tortuous and angulated anatomy of the region. OBJECTIVES Our objective was to determine the proximal landing accuracy of zone 2-targeted TEVARs following carotid-subclavian revascularization (CSR) and its impact on clinical outcomes. METHODS Retrospective review of patients that underwent CSR for zone 2 endograft delivery at a tertiary institute between January 2008 and March 2018 was conducted. Technical outcomes were assessed by examining the incidence of intraoperative corrective maneuvers, 1a endoleaks and reinterventions. Distance to target and incidence of LSA stump filling were examined as radiographic markers of landing accuracy. RESULTS Zone 2-targeted TEVAR with CSR was performed in 53 patients for treatment of dissections (49%), aneurysms (30%) or trauma (21%). Nine (17%) cases required intraoperative corrective procedures: 5 (9%) proximal cuffs due to type 1a endoleak and 4 (8%) left common carotid artery (LCCA) stenting due to inadvertent coverage. Cases performed using higher resolution hybrid fluoroscopy machine compared to mobile C-arm were associated with increased proximal cuff use (OR 8.8; 95% CI 1.2-62.4). Average distance between the proximal edge of the covered graft to LCCA was 8 ± 1 mm and larger distances were not associated with higher rates of 1a endoleak. Twenty-eight (53%) cases of antegrade LSA stump filling were noted on follow-up imaging, but were not associated with higher rates of reinterventions (OR 0.8, 95% CI [0.2-4.6]). Three (6%) patients had a stroke within 30 days and 4 (8%) patients expired within 1 month. Intraoperative corrective maneuvers, post-operative 1a endoleak and reinterventions were not associated with higher rates of stroke or mortality. CONCLUSION Using current endografts and imaging modalities, zone 2-targeted TEVARs have suboptimal technical accuracy.

Abstract
OBJECTIVE Thoracic endovascular aortic repair (TEVAR) has become the most common surgical procedure for treatment of descending thoracic aortic pathology. Cervical debranching in the form of carotid-subclavian bypass or transposition (CSBT) and carotid-carotid bypass (CCB) has enabled the use of TEVAR for the treatment of more complex anatomy involving the arch. The present study examined the effects of concomitant cervical bypass on the perioperative outcomes of TEVAR. METHODS The American College of Surgeons National Surgical Quality Improvement Program files (2005-2017) were reviewed. Using the Current Procedural Terminology codes, all patients who had undergone TEVAR were identified and were divided into three groups: TEVAR, TEVAR with one bypass (CSBT or CCB), and TEVAR with two bypasses (CSBT and CCB). The patient characteristics and perioperative outcomes of the three groups were compared. Multivariable analysis was performed to determine the factors associated with mortality. RESULTS A total of 3281 patients had undergone TEVAR and 10% had also undergone one or more debranching procedure (one bypass, 9%; two bypasses, 1%). The frequency of debranching had increased from 3.4% to 10.9% (P = .01) during the study period. Significant differences were found among the three groups in age, sex, smoking history, urgency of surgery, and anesthesia technique. The patients who had undergone TEVAR with cervical debranching had had significantly greater morbidity, longer operating times, and longer hospital stays compared with those who had undergone TEVAR alone. The mortality of TEVAR with two bypasses (22.6%) was significantly greater than that of TEVAR alone (7.5%) and TEVAR with one bypass (6.8%; P < .01). The total morbidity (30.9% vs 35.1% vs 67.7%; P < .001) and stroke rate (3% vs 7.5% vs 12.9%; P < .0001) increased with the increasing number of bypasses. A subgroup analysis of patients who had undergone TEVAR with one bypass showed no significant differences in mortality between TEVAR plus CSBT (6.6%) vs TEVAR plus CCB (8.8%; P = .63). Multivariable analysis showed that TEVAR with two bypasses was associated with significantly increased mortality compared with TEVAR alone (odds ratio [OR], 4.33; 95% confidence interval [CI], 1.75-10.73) and TEVAR with one bypass (OR, 3.44; 95% CI, 1.24-9.51). Older age (OR, 1.74; 95% CI, 1.42-2.13), dependent functional status (OR, 1.48; 1.00-2.19), dialysis (OR, 2.61; 95% CI, 1.57-4.33), and emergent status (OR, 3.66; 95% CI, 2.73-4.90) were also associated with mortality. CONCLUSIONS TEVAR with concomitant cervical debranching has been increasingly used to treat complex aortic pathology but is associated with significantly worse outcomes than TEVAR alone. As advanced endovascular technology to treat the aortic arch emerges, the outcomes of open surgical debranching in the present study constitute an important benchmark for comparison.

Abstract
OBJECTIVE An analysis was conducted of early and midterm outcomes of a large series of patients treated with in situ laser fenestration (ISLF) during thoracic endovascular aortic repair (TEVAR) of acute and subacute complex aortic arch diseases, such as Stanford type A aortic dissection (TAAD), type B aortic dissection (TBAD) requiring proximal sealing at zone 2 or more proximal, thoracic aortic aneurysm or pseudoaneurysm, and penetrating aortic ulcer. We present the perioperative and follow-up outcomes and discuss the rate of complications. METHODS This is a retrospective review of prospectively collected data from January 2017 to March 2019 of patients treated with TEVAR and ISLF of aortic arch branches at a large tertiary academic institution in an urban city in China. Preoperative, intraoperative, and follow-up clinical and radiographic data are analyzed and discussed. RESULTS A total of 148 patients presented with symptomatic and acute or subacute TAAD, TBAD, thoracic aortic aneurysm, or penetrating aortic ulcer for a total of 183 arch vessels. There were 105 men and 43 women, 21 to 79 years of age (mean, 54.9 ± 12.9 years). Time from symptom onset to time of surgery was an average of 7 ± 3 days. Survivor follow-up duration ranged from 5 to 24 months (mean, 15 ± 5 months). Single-vessel fenestration was carried out in 124 cases, two-vessel fenestration in 13 cases, and three-vessel fenestration in 11 cases. There were four cases with technical failure to laser fenestration, with a technical success rate of 97.3%. Postoperatively, there were seven cases of endoleak (4.7%; one type IB distal from the left subclavian artery branch stent graft, three type IIIC at the fenestration site, and three type II), three retrograde dissections (2.0%), and five strokes (3.4%); death occurred in three patients with 30-day mortality of 2.9%, and two deaths occurred during follow-up for 3.4% mortality at an average 15 months of follow-up. There was no branch stent graft occlusion or spinal ischemia postoperatively or during follow-up. The distribution of arch diseases varied significantly according to the number of vessels that were laser fenestrated; TAAD was more likely to receive multivessel laser fenestrations, and TBAD was more likely to receive single-vessel fenestration (P < .001). The rate of complications was distributed differently between the three ISLF groups, with more complications occurring in multivessel fenestrations. However, a statistical weakening was observed when frequency of complications between the three groups was stratified by type of arch disease. The complication rate varied significantly between the different arch diseases, higher in TAAD than in TBAD (P = .008). CONCLUSIONS ISLF during TEVAR for treatment of acute and subacute complex aortic arch diseases in the proximal aortic arch is safe and effective on the basis of these early to midterm follow-up data of a large cohort. However, care should be taken in intervening on TAAD using TEVAR with adjunctive multivessel laser fenestration. Continued investigation of TEVAR and adjunctive ISLF is needed to elucidate the long-term outcomes of this minimally invasive treatment for complex aortic arch disease in an urgent setting.

Abstract
Summary: Background: To evaluate trends in frequency, mortality and treatment for non-traumatic vascular emergencies (VE) in the US. Methods: VE in the Nationwide Inpatient Sample (2005–2014) were identified. ICD-9 CM diagnosis and procedures codes captured six common VE. Results: 228,210,504 emergency admissions with 317,396 procedures for VE were estimated. Mean age was 67.8 years and were primarily men (56.1 %; p < 0.0001). The commonest VE was Acute Limb Ischemia (ALI) (82.4 %) followed by ruptured AAA (10.8 %) and Acute Mesenteric Ischemia (4.71 %). VE increased from 132.8 per 100,000 admissions in 2005 to 153.6 in 2014 (p < 0.001), with mortality decrease for all VE (13.8 % vs. 9.1 %; p < 0.0001). Length of stay decreased (median 8 vs. 7 days; p < 0.0001) but cost of care increased (median $ 25,443 vs. $ 29,353; p < 0.0001). Endovascular treatment increased overall for VE from 23.7 % in 2005 to 37.2 % in 2014 (p < 0.0001). Hospital mortality for VE decreased overall, except ruptured thoracoabdominal aortic aneurysm with mortality decrease with endovascular treatment (34.3 vs. 11.1; p = 0.04) and mortality increase with open treatment (44.7 vs. 47.6; p = 0.06). ALI overall mortality decreased from 8.1 % to 5.7 % (p < 0.0001) due to reduced open surgical mortality from 9.6 % to 7.4 % (p < 0.0001); endovascular mortality did not improve over time (4.0 % vs. 3.4 %; p = 0.45). Hospital mortality also increased for endovascular treatment of ruptured thoracic aortic aneurysm (rTAA) from 14.9 % to 27.4 % (p = 0.0003) during this period. Conclusions: VE frequency increased with a decrease in overall mortality over time. Overall hospital stay has decreased but with an increase in the cost of care. Open surgical mortality for VE has also decreased overall, suggesting perioperative care improvements, with the exception of ruptured thoracoabdominal aortic aneurysm. Endovascular utilization for VE has significantly increased; associated with lower mortality for most VE, although an increase in hospital mortality after endovascular repair of rTAA was seen. This may be due to an increased implementation of endovascular repair for patients not previously eligible for surgery due to high risk. We recommend careful selection of patients for rTAA treatment as mortality has increased despite endovascular therapy and at an increased cost of care.

Occlusion of the Celiac Artery during Endovascular Thoracoabdominal Aortic Aneurysm Repair Is associated with Increased Perioperative Morbidity and Mortality. Ann Vasc Surg 2020; 66:200-211. [PMID: 32035263 DOI: 10.1016/j.avsg.2020.01.102] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 01/25/2020] [Accepted: 01/26/2020] [Indexed: 12/20/2022]
Abstract
BACKGROUND Some studies suggest that celiac artery coverage during elective endovascular thoracoabdominal aortic aneurysm (TAAA) repair is safe given sufficient collateralization of visceral organ perfusion from the superior mesenteric artery. However, there is concern that celiac artery coverage may lead to increased risk of foregut or spinal cord ischemia with an attendant increased risk of mortality. We sought to investigate rates of bowel ischemia, spinal cord ischemia, and 30-day mortality associated with celiac artery coverage during TEVAR and complex EVAR. METHODS The Society for Vascular Surgery Vascular Quality Initiative database was queried for TEVAR and complex EVAR cases from 2012 to 2018. Inclusion criteria included TAAA pathology and endograft extension to aortic zone 6. Patients with aortic rupture, trauma, prior thoracic aortic surgery, known preoperative occlusion of the left subclavian superior mesenteric, or celiac arteries were excluded. Cases with intraoperative celiac artery occlusion (CAO) were compared retrospectively to cases with celiac artery preservation (CAP). Primary outcomes included 30-day mortality and a composite end point of 30-day mortality, spinal cord ischemia (transient or permanent lower extremity neurologic deficit), and bowel ischemia (colonoscopic evidence of ischemia, bloody stools in a patient who dies prior to colonoscopy or laparotomy, or other documented clinical diagnosis). Univariable comparisons were performed using chi-squared tests and Student's t-tests, as appropriate. Multivariable logistic regression analyses were employed to identify independent predictors of outcome. RESULTS There were 628 cases identified for inclusion in the study. Patients undergoing CAO (n = 44) were more likely to be female or to have higher rates of preoperative spinal drain use, American Society of Anesthesiologists score ≥3, low preop hemoglobin, and/or symptomatic presentation, but fewer mean number of aortic zones covered. CAO was associated with higher 30-day mortality (5 of 44, 11%) compared to CAP (23 of 584, 4%), P = 0.039. The composite end point occurred at a significantly greater proportion for those who had CAO (10 of 44, 23%) compared to CAP (53 of 584, 9%, P = 0.008), driven by higher rates of 30-day mortality and bowel ischemia (9% vs. 2%, P = 0.026). By multivariate analysis, CAO was predictive of 30-day mortality (odds ratio [OR] = 3.9, 95% confidence interval [CI] = 1.1-13.8, P = 0.04) and the composite endpoint (OR = 3.0, 95% CI = 1.1-8.5, P = 0.03). Increasing procedure time was also associated with 30-day mortality (OR = 1.4, 95% CI = 1.1-1.7, P < 0.001) and the composite end point (OR = 1.4, 95% CI = 1.1-1.6, P < 0.001). CONCLUSIONS For those treated for TAAAs, CAO was independently predictive of increased 30-day mortality and a composite end point of perioperative mortality, spinal cord ischemia, and bowel ischemia. When treating patients with extensive aortic aneurysmal disease, physicians should attempt to preserve the celiac artery, by revascularization or avoiding ostium coverage, whenever feasible.

Abstract
OBJECTIVE Despite endovascular advances in fenestrated and branched devices, thoracic endovascular aortic repair (TEVAR) for arch pathologies remains challenging. The aim of this study was to provide a contemporary review on the current evidence for in situ fenestration during TEVAR and to evaluate its short- and mid-term clinical outcome in the management of arch pathology. METHODS A systematic literature review on in situ fenestration of thoracic aortic stent-graft from January 2003 to September 2018 was performed under the instruction of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. RESULTS Our initial search yielded 169 studies, of which 21 articles were relevant to the topic and were finally included. One hundred and forty-five in situ fenestration procedures in 99 patients were reviewed, involving 25 innominate arteries (17%), 33 left common carotid arteries (23%) and 87 left subclavian arteries (60%). Twelve patients (12/99, 12%) had two-vessel fenestration and three-vessel fenestration was performed in 17 patients (17/99, 17%). Technical success was achieved in 136 arteries (136/145, 93%). Talent/Valiant with monofilament twill woven polyester fabric was the most common (50/99, 51%) stent-graft used for fenestration. Three methods reported for in situ fenestration were needle, laser and radiofrequency. Needle was the most frequently used device for fenestration, which was performed in 60 patients (60/99, 61%). Three patients (3/99, 3%) died with 30 days, none were in situ fenestration TEVAR procedure-related. Perioperative complications including one (1%) retrograde type A aortic dissection, two (2%) type II endoleaks, and three (3%) strokes were reported. The pooled estimate for overall technical success, perioperative mortality and stroke was 88.3% (95% CI, 78.6%-93.9%), 5.9% (95% CI, 2.5%-13.4%) and 9.5% (95% CI, 4.1%-20.6%), respectively. Four patients (4/96, 4%) died during follow-up, none were aortic-related. All the fenestration bridging stents were reportedly patent, with only 1 (1/96, 1%) asymptomatic left subclavian stent stenosis. Two patients (2/96, 2%) with type II endoleak from left subclavian artery required secondary intervention. CONCLUSION In situ fenestration appeared to be a feasible and effective method to extend proximal landing zone during TEVAR. It had an acceptable short-term result with high technical success and low fenestration related morbidity. Long-term durability data were lacking, and there was no high level evidence to recommend the routine use of in situ fenestration TEVAR for the management of arch pathology.

Abstract
Purpose: To analyze the distribution of air bubbles in the supra-aortic vessels during thoracic stent-graft deployment in zones 2 and 3 in an aortic flow model. Materials and Methods: Ten identical, investigational, tubular, thoracic stent-grafts were deployed in a glass aortic flow model with a type I arch: 5 in zone 2 and 5 in zone 3. A pulsatile pump generated a flow of 5 L/min with systolic and diastolic pressures (±5%) of 105 and 70 mm Hg, respectively. The flow rates (±5%) were 300 mL/min in the subclavian arteries, 220 mL/min in the vertebral arteries, and 400 mL/min in the common carotid arteries (CCAs). The total amounts of air released in each supra-aortic branch and in the aorta were recorded. Results: The mean amounts of air measured were 0.82±0.23 mL in the zone-2 group and 0.94±0.28 mL in the zone-3 group (p=0.49). In the zone-2 group compared with zone 3, the amounts of released air were greater in the right subclavian artery (0.07±0.02 vs 0.02±0.02 mL, p<0.01) and right CCA (0.30±0.8 vs 0.18±07 mL, p=0.04). There were no differences between the groups concerning the mean amounts of air measured in the right vertebral and all left-side supra-aortic branches. The amount of air released in the descending aorta was significantly higher in the zone-3 group vs the zone-2 group (0.48±0.12 vs 0.13±0.08 mL, p<0.01). Small bubbles were observed continuously during deployment, whereas large bubbles appeared more commonly during deployment of the proximal stent-graft end and after proximal release of the stent-graft. Conclusion: Air is released into all supra-aortic branches and the descending aorta during deployment of tubular thoracic stent-grafts in zones 2 and 3 in an aortic flow model. Higher amounts of air were observed in right-side supra-aortic branches during deployment in zone 2, whereas significantly greater amounts of air were observed in the descending aorta during deployment in zone 3.

Abstract
BACKGROUND Cardiac and cerebrovascular complications are major causes of adverse outcomes following thoracic endovascular aortic repair (TEVAR). The benefits of statins have been established, but little is known about their impact on patients undergoing TEVAR. We investigated whether chronic statin use protected against early postoperative major adverse cardiac and cerebrovascular events (MACCEs) after TEVAR. METHODS We retrospectively reviewed 211 patients who underwent TEVAR between February 2013 and March 2017 classified into two groups, those with acute aortic syndrome (AAS, N.=79) and those without (non-AAS, N.=132). Patients were subdivided according to preoperative statin therapy for ≥3 months or not. The primary endpoint was 30-day MACCE, defined as myocardial infarction, stroke, arrhythmia, cardiovascular death, or cerebrovascular death. Acute kidney injury (AKI) occurrence within 48 hours was also evaluated. Multivariate logistic regression analysis was performed to identify independent risk factors for MACCEs and AKI. RESULTS Incidence of MACCEs (1% vs. 11%, P=0.019) was significantly lower in the statin group than in the no-statin group in non-AAS patients. Multivariate logistic regression analysis revealed statin use (odds ratio 0.85, 95% confidence interval 0.01-0.95, P=0.046) as an independent predictor for MACCE in non-AAS patients. The AKI incidence was significantly higher in the statin group than in the no-statin group in AAS patients (44% vs. 15%, P=0.018). CONCLUSIONS In patients undergoing TEVAR, chronic statin use was associated with reduced 30-day MACCEs in non-AAS patients, but not in AAS patients. It might rather be associated with increased risk of AKI in AAS patients.
