Abstract
BACKGROUND Obesity is increasing in prevalence globally and within the cohort of vascular surgical patients, leading to poorer outcomes. There are few data on endoleak as a complication of AAA surgery in obese patients. The aim of this study was to use large scale registry data from the Global Registry for Endovascular Aortic Treatment (GREAT) to interrogate any relationship between obesity and endoleak following endovascular aneurysm repair (EVAR) using a Gore Excluder device (W. L. Gore & Associates, Newark, DE, USA), in order to guide treatment recommendations in the future. METHODS A retrospective review of the GREAT Registry was carried out and patients who were recorded as having a postoperative endoleak requiring intervention were included. Patient demographics including Body Mass Index (BMI), aneurysm parameters and on- or off-instructions for use (IFU) were recorded. Ruptured AAA were excluded. RESULTS Data were obtained for 3326 patients with an operation date between August 25, 2010 and September 22, 2019. Obese patients were significantly less likely to have a Type 1 endoleak (Fisher's Exact P value=0.006), and the association was maintained in a multiple logistic regression model which controlled for age, gender, neck angulation and off IFU device use (OR=0.33, P=0.01). CONCLUSIONS Among AAA patients treated with a Gore Excluder device (W. L. Gore & Associates), a higher BMI category was associated with a lower risk of Type 1 endoleak requiring reintervention. Further work needs to be carried out to assess our findings in other patient cohorts.

Abstract
PURPOSE Endovascular aortic repair (EVAR) is the method of choice for most abdominal aortic aneurysm (AAA) patients requiring intervention. However, chronic aortic neck dilatation (AND) following EVAR progressively weakens the structural seal between vessel and endograft and compromises long-term results of the therapy. This experimental ex vivo study seeks to investigate mechanisms of AND. MATERIALS AND METHODS Porcine abdominal aortas (n=20) were harvested from slaughterhouse pigs and connected to a mock circulation. A commercially available endograft was implanted (n=10) or aortas were left untreated as controls (n=10). Vascular circumferential strain was assessed via ultrasound in defined aortic segments as a parameter of aortic stiffness. Histology and aortic gene expression analysis were performed to investigate potential changes of aortic wall structure and molecular differences due to endograft implantation. RESULTS We found that endograft implantation acutely induces a significant stiffness gradient directly at the interface between stented and unstented aortic segments under pulsatile pressure. Comparing stented aortas with unstented controls, we detected increased aortic expression levels of inflammatory cytokines (Il6 and Ccl2) and matrix metalloproteinases (Mmp2 and Mmp9) after 6 hours of pulsatile pressurization. This effect, however, was abolished when repeating the same experiment under 6 hours of static pressure. CONCLUSIONS We identified endograft-induced aortic stiffness gradients as an early trigger of inflammatory aortic remodeling processes that might promote AND. These results highlight the importance of adequate endograft designs to minimize vascular stiffness gradients and forestall late complications, such as AND. CLINICAL IMPACT AND may compromise the long-term results following endovascular aortic repair. However, the mechanisms behind the underlying detrimental aortic remodeling are still unclear. In this study we find that endograft-induced aortic stiffness gradients induce an inflammatory aortic remodeling response consistent with AND. This novel pathomechanistic insight may guide the design of new aortic endografts that minimize vascular stiffness gradients and forestall late complications such as AND.

Acta Biomater 2023; 161:170-183. [PMID: 36849029 DOI: 10.1016/j.actbio.2023.02.028] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 01/25/2023] [Accepted: 02/20/2023] [Indexed: 02/27/2023]
Abstract
The effects of thoracic endovascular repair (TEVAR) on the biomechanical properties of aortic tissue have not been adequately studied. Understanding these features is important for the management of endograft-triggered complications of a biomechanical nature. This study aims to examine how stent-graft implantation affects the elastomechanical behavior of the aorta. Non-pathological human thoracic aortas (n=10) were subjected to long-standing perfusion (8h) within a mock circulation loop under physiological conditions. To quantify compliance and its mismatch in the test periods without and with a stent, the aortic pressure and the proximal cyclic circumferential displacement were measured. After perfusion, biaxial tension tests (stress-stretch) were carried out to examine the stiffness profiles between non-stented and stented tissue, followed by a histological assessment. Experimental evidence shows: (i) a significant reduction in aortic distensibility after TEVAR, indicating aortic stiffening and compliance mismatch, (ii) a stiffer behavior of the stented samples compared to the non-stented samples with an earlier entry into the nonlinear part of the stress-stretch curve and (iii) strut-induced histological remodeling of the aortic wall. The biomechanical and histological comparison of the non-stented and stented aortas provides new insights into the interaction between the stent-graft and the aortic wall. The knowledge gained could refine the stent-graft design to minimize the stent-induced impacts on the aortic wall and the resulting complications. STATEMENT OF SIGNIFICANCE: Stent-related cardiovascular complications occur the moment the stent-graft expands on the human aortic wall. Clinicians base their diagnosis on the anatomical morphology of CT scans while neglecting the endograft-triggered biomechanical events that compromise aortic compliance and wall mechanotransduction. Experimental replication of endovascular repair in cadaver aortas within a mock circulation loop may have a catalytic effect on biomechanical and histological findings without an ethical barrier. Demonstrating interactions between the stent and the wall can help clinicians make a broader diagnosis such as ECG-triggered oversizing and stent-graft characteristics based on patient-specific anatomical location and age. In addition, the results can be used to optimize towards more aortophilic stent grafts.

Abstract
This review discusses the impact of endovascular aneurysm repair on cardiovascular (CV) hemodynamics and the role of stent-graft material, i.e., polytetrafluoroethylene (PTFE) vs. polyester in post-procedural outcomes. Endovascular aneurysm repair has been widely employed in the last decades for thoracic and abdominal aneurysm repair. However, aortic endografts are stiff and alter the native flow hemodynamics. This failure to simulate the native aorta could lead to added strain on the heart, manifesting as increased left ventricular strain, higher pulse pressure, and congestive heart failure later. This could result in adverse CV outcomes. Also, evidence is mounting to support the implication of stent-graft materials, i.e., PTFE vs. polyester, in adverse post-procedural outcomes. However, there is an absence of level one evidence. Therefore, the only way forward is to plan and perform a randomised controlled trial to demonstrate the alterations in the CV hemodynamics in the short and long run and compare the available stent-graft materials regarding procedural and clinical outcomes. We believe the best solution, for now, would be to reduce the stented length of the aorta. At the same time, in the longer term, encourage continuous improvement in stent-graft materials and design.

Abstract
OBJECTIVES The purpose of this study was to determine the relationship between the changes in diastolic function and their association with cardiac biomarkers in the perioperative period in patients undergoing complex endovascular aortic repair. DESIGN Prospective observational study. SETTING Single-center academic hospital, central teaching hospital in Warsaw, Poland. PARTICIPANTS The study comprised 27 high-risk patients scheduled for elective endovascular repair of aortic aneurysm. INTERVENTIONS Complex endovascular procedure using branched endograft of the thoracoabdominal aorta. Branches of the stent grafts included renal arteries, the superior mesenteric artery, and the celiac trunk. MEASUREMENTS AND MAIN RESULTS The primary outcome was to evaluate changes in diastolic function parameters assessed with transthoracic echocardiography at two and 24 hours postoperatively. The major secondary outcomes were changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) and troponin I concentrations, systolic function parameters, hemodynamic parameters at two and 24 hours, length of hospital stay, and 30-day mortality. There was a reduction in e' wave velocity on both the septal and lateral sides at two hours compared with the baseline (p = 0.041 and p = 0.05, respectively). There was an increase in both NT-proBNP and troponin I concentrations after surgery (p = 0.002 and p = 0.034, respectively), with troponin I peaking two hours after surgery and NT-proBNP peaking 24 hours after surgery. CONCLUSIONS Patients undergoing a branched endovascular aortic repair of a thoracoabdominal aortic aneurysm experience a cardiac insult that manifests with deterioration in diastolic parameters and concomitant increases of troponin and NT-proBNP concentrations. Additional large-scale prospective studies are required to confirm this phenomenon.

Abstract
BACKGROUND There is currently limited data assessing the long-term consequences of thoracic endovascular aortic repair (TEVAR) in otherwise healthy aortic segments remote from the site of endograft coverage. The aim of this study is to retrospectively evaluate aortic remodeling and long-term outcomes of blunt thoracic aortic injury (BTAI) patients treated with TEVAR. Our hypothesis is that significant changes to the aorta proximal to the graft-covered segment are suspected following TEVAR. METHODS An institutional review board-approved retrospective review of patients who underwent TEVAR for BTAI at a level I trauma center from 2004 to 2018 was performed. Forty-six patients were identified and of these, 32 patients with high-resolution computed tomographic angiography imaging follow-up were included in the study. Computed tomographic angiography measurements of aortic dimensions and branch vessels proximal, distal, and adjacent to the stent grafted segment were recorded preprocedure and postprocedure and analyzed. Primary device-related outcomes such as birdbeaking, mural thrombus, stent migration, and persistent endoleak were assessed. Patient outcomes including mortality, graft-related morbidity, and need for secondary interventions were also analyzed. RESULTS Mean follow-up of the selected patients in the study was 1.52 y (range, 0.06-8.0 y). Following TEVAR, the ascending aortic length increased significantly (mean 5.7 ± 4.6 mm, P < 0.001). The mean diameters of the ascending aorta (1.5 ± 1.5, P < 0.001 mm), the midaortic arch (1.3 ± 1.7 mm, P < 0.001), and proximal and the distal endograft landing zones (1.9 ± 2.1 mm and 2.2 ± 1.6 mm, respectively, P < 0.001) also increased significantly following TEVAR. Clinically relevant device-related outcomes occurred with the presence of endograft infolding and subsequent development of endograft mural thrombus (P < 0.001). The need for secondary intervention following TEVAR for BTAI was associated with endograft mural thrombus (P < 0.05). CONCLUSIONS TEVAR for BTAI causes significant geometric changes in the aorta proximal to the stented grafted segment of the aorta. Direct consequences of the graft at the stented segment includes mural thrombus development within the endograft which was associated with the need for secondary intervention. Although clinical significance is yet to be determined, post-TEVAR changes in aortic architecture warrant continued aortic surveillance following BTAI.

Abstract
BACKGROUND We report a rare case of delayed, symptomatic thoracic endograft thrombosis after the initial thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury which was successfully retreated with a redo TEVAR, followed by open conversion due to recurrent partial occlusion of the distal edge of the endografts. METHODS Two years ago, a 22-year-old man had undergone an emergency TEVAR for blunt thoracic aortic injury. A Zenith Cook 22 × 100 mm (Cook Incorporated, Bloomington, IN) endograft was used. Six months later, he underwent an emergency endovascular relining of the endograft using the same type of device. The multiorgan perfusion was completely restored except for the spinal cord injury. After 8 months, a recurrent partial occlusion of the distal edge of the second graft was documented. The thoracic aorta was replaced with a 22-mm silver-coated graft (Maquet Spain, SLU). RESULTS Histology examination showed a neointimal formation and thickening and fibrosis of the inner 1/3 of the media with loss of smooth muscle cells and increase of the elastic fibers. CONCLUSIONS The need for secondary interventions or open conversion because of potential complications after TEVAR for traumatic aortic injury is an additional consideration when weighing the risks and benefits of endovascular repair and subsequent surveillance strategies.

Abstract
Pulse wave velocity (PWV) is a valid, clinically feasible marker of arterial stiffening, and a strong predictor of outcomes. The present study aimed to compare aortic elastic properties in patients with abdominal aortic aneurysms (AAA), with or without coronary artery disease (CAD), as well as healthy individuals. A total of 130 patients with AAA, eligible for interventional repair, and 30 healthy individuals, comprising the control group (HC), were enrolled. Presence of CAD was identified by coronary angiography. Aortic PWV (aPWV) was measured using the Arteriograph. aPWV was found considerably higher in AAA patients compared with HC group (11.5 ± 2.9 vs 7.3 ± 1.6 m/s, P < .001). Importantly, among patients with AAA, those with concomitant CAD (n = 41) had greater aPWV than those without CAD (12.5 ± 2.9 vs 11.0 ± 3.0 m/s, P = .03). In receiver operator curve (ROC) analysis, a value of aPWV above 12.8 m/s was identified to correlate with the presence of CAD in the AAA patient population. After adjustment for confounders, including hypertension which is one of the major risk factors for abdominal aneurysms, multivariate logistic regression analysis revealed that this aPWV cutoff remained independently associated with presence of CAD [odds ratio = 1.64, 95% confidence interval =1.19-4.08, P = .03]. The coexistence of CAD and AAA is characterized by a greater arterial stiffness. This finding should be taken into consideration when selecting endovascular stents with more favorable elastic properties. Moreover, AAA patients with high aPWV (>12.8 m/s) are more likely to also have CAD, and this may be considered by vascular surgeons when evaluating patients' cardiovascular risk.

Abstract
BACKGROUND Endovascular intervention for chronic symptomatic type B aortic dissection (CS-TBAD) induces aortic wall stress with negative hemodynamic cardiovascular consequences. CS-TBAD risks increased morbidity and mortality due to septum maturation with significant impact on false lumen modulation, and partial lumen thrombosis conveying the worst outcome. The aim of the TIGER technique is total aortic remodeling with true lumen expansion, false lumen regression and complete thrombosis, and stabilization of overall aortic diameter. METHODS We report 5 cases of aortic dissection with a mean follow-up of 16 months (6-28 months). All had aneurysmal dilation, with 3 having acute pan aortic dissection and 2 having CS-TBAD. All were managed by sTaged HybrId sinGle lumEn Reconstruction (TIGER). Our first approach was to create one single lumen from the supraceliac, infradiaphragmatic aorta to both common iliac arteries with open surgical patching of the visceral arteries; then, we performed a TEVAR 3 months later. RESULTS Three patients required a left subclavian artery chimney graft and one required bilateral subclavian to carotid artery transposition. No spinal drainage was required, and all patients had intraoperative transesophageal echo for wire guidance. We had no aortic rupture or retrograde type A dissection, and we experienced no renal, visceral, cardiac, pulmonary, or spinal complications. All patients, but one, went off their antihypertensive medication. All patients had normal estimated glomerular filtration rate postoperatively, and they all demonstrated accelerated aortic modulation. CONCLUSIONS TIGER was not only effective at the semiacute stage to initiate remodeling and prevent malperfusion, it also facilitated a straightforward TEVAR at stage 2, which was made easier by avoiding visceral branch stenting. Moreover, it decreased the length of aortic segment, which was stented, thereby avoiding critical shattering, branch dislodgment, and visceral compromise; spinal ischemia; and negative cardiovascular consequences.

Abstract
Endovascular repair of descending thoracic aorta (DTA) is considered as first interventional option for most part of the aortic disorders. However, many unmet needs and issues are still limiting its applicability. One of the major limitations is related to the existing gaps in evidence. Clear and robust evidence is still needed in many aspects of the management of DTA pathologies. In numerous clinical scenarios, adequate trials are lacking. Besides those gaps in evidence, it is well recognized that thoracic endografting (TEVAR) is technically evolving in order to overcome technical and device-related complications and limitations. We can deploy endografts in any aortic segment: in the descending, in the ascending, in the arch, even preserving aortic branches. Nevertheless, from the pure technical point of view, current generations of endografts still need more development and improvement. Durability remains the major concern for any endovascular treatment, and thoracic endografting is not an exception. As Galenus said, the physician is only nature's assistant, thoracic endograft should also follow the natural anatomy instead of fighting against it. We will focus the following pages on the graft conformability and compliance, both related to durability and safety of thoracic endografting. We will review the current knowledge and concerns associated with the anatomical and hemodynamic modifications induced by the thoracic endograft strength, stiffness and straightness and their implications for the future thoracic endograft designs.

Abstract
PURPOSE To identify the perioperative factors associated with aneurysm size changes after endovascular aortic aneurysm repair (EVAR). METHODS Between August, 2008 and December, 2014, 187 patients underwent EVAR treatment in our institution. The subjects of this study were 135 of these patients without peripheral artery disease, who were followed up with computed tomography (CT) for 3 years. Significant aneurysm size change was defined as sac size change of more than 5 mm from the baseline. RESULTS Sac enlargement was identified in 25 patients (18.5%) and sac shrinkage was identified in 59 (43.7%) patients. The factors associated with sac enlargement were postoperative pulse wave velocity (OR: odds ratio 3.80, p = 0.047), prevalence of a type 2 endoleak 1 week after surgery (OR 4.26, p = 0.022), inner diameter (OR 1.10, p = 0.005), and distance from the lower renal artery to the terminal aorta (OR 1.05, p = 0.017). The factors associated with sac shrinkage were prevalence of a type 2 endoleak (OR 0.09, p < 0.001) and preoperative pulse wave velocity (OR 0.32, p = 0.022). The factors independently associated with type 2 endoleak were the use of an Excluder device (OR 3.99, p = 0.002) and the length of the aneurysm (OR 1.02, p = 0.027). CONCLUSION Inner diameter, treatment length, perioperative pulse wave velocity, and type 2 endoleak were associated with sac size changes after EVAR.

Pulmonary Function and Arterial Stiffness in Chronic Heart Failure. BIOMED RESEARCH INTERNATIONAL 2016; 2016:5478394.

Abstract
Arterial stiffness contributes to heart failure and is decreased by angiotensin receptor blockers (ARBs). This cross-sectional study aimed to assess associations of lung function and ARB with arterial stiffness in patients with chronic heart failure. 354 outpatients (168 males; 186 females; 68.2 ± 7.2 years old) with chronic heart failure were evaluated. Lung function parameters, including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and FEV1 to FVC ratio (FEV1/FVC), were assessed. The cardio-ankle vascular index (CAVI) was used to estimate arterial stiffness. Unadjusted correlation analyses revealed a positive association of CAVI with ARB but not ACEI, and a negative correlation with FEV1 (r = −0.2987, p < 0.0001). Multiple stepwise regression analyses showed that ARB and FEV1 (p < 0.0001) were independent predicting factors for CAVI. These findings suggest that reduced pulmonary function is associated with increased CAVI. Pulmonary function protection could be used to improve the prognosis in heart failure, but additional studies are necessary.
