Luo ZR, Wang ZS, Chen YX, Chen LW. Outcomes of endovascular therapy for Stanford type B aortic dissection in patients with sleep apnea syndrome. J Vasc Surg 2024; 80:1437-1447.e2. [PMID: 38925349 DOI: 10.1016/j.jvs.2024.06.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2024] [Revised: 05/23/2024] [Accepted: 06/15/2024] [Indexed: 06/28/2024]
Abstract
OBJECTIVE This study aimed to determine the influences of varying severity of sleep apnea syndrome (SAS) on the outcomes after thoracic endovascular aorta repair (TEVAR) in patients with Stanford type B aortic dissection (TBAD). METHODS This observational study focused on individuals with TBAD plus SAS who received TEVAR between January 2018 and December 2022. Patients were divided into groups according to the results of the portable sleep-breathing monitoring systems: mild SAS (MSAS) and moderate-to-severe SAS (MSSAS). Clinical profiles were collected and analyzed. RESULTS A total of 121 cases with TBAD plus SAS who underwent TEVAR were enrolled in this study. Two groups were formed by stratifying these cases: MSAS (74 cases) and MSSAS (47 cases). The MSSAS cases were found to be older relative to MSAS cases (51.7 ± 8.3 years vs 57.1 ± 12.8 years; P = .012) and had a higher body mass index (BMI; 25.7 ± 2.3 kg/m2vs 27.0 ± 2.3 kg/m2; P = .038). The investigation did not find any appreciable differences between the MSAS and MSSAS groups in terms of complications (endoleak, P = .403; stent-induced new entry, P >.999; and stent displacement: P >.999). However, the MSSAS group exhibited a significantly higher overall mortality rate compared with the MSAS group (log-rank P = .027). The tendency continued when examining cases with Marfan syndrome combined with MSSAS, where the overall mortality rate was significantly greater compared with Marfan syndrome cases with MSAS (log-rank P = .037). The absence of a significant difference was noteworthy in the freedom from reintervention between the MSAS and MSSAS groups (log-rank P = .278). The overall mortality rate was significantly higher in MSSAS group even after adjusting for varying potential confounders in the multivariate cox regression analysis (hazard ratio [HR], 1.875; 95% confidence interval [CI], 1.238-2.586; P = .012). A markedly higher rate of distal stent dilation in the MSSAS group was also observed compared with the MSAS group (HR, 2.5 mm/year [95% CI, 2-3 mm/year] vs HR, 4 mm/year [95% CI, 2.0-5.5 mm/year]; P = .029). CONCLUSIONS MSSAS is associated with a significantly higher risk of overall mortality and dilation rate of the distal stent after TEVAR for TBAD patients. Hence, aggressive efforts to reverse the severity of SAS in time in these individuals seem to be necessary.

Abstract
This study aimed to establish a predictive model for the risk of post-thoracic endovascular aortic repair (TEVAR) post-implantation syndrome (PIS) in type B aortic dissection (TBAD) patients, assisting clinical physicians in early risk stratification and decision management for high-risk PIS patients. This study retrospectively analyzed the clinical data of 547 consecutive TBAD patients who underwent TEVAR treatment at our hospital. Feature variables were selected through LASSO regression and logistic regression analysis to construct a nomogram predictive model, and the model's performance was evaluated. The optimal cutoff value for the PIS risk nomogram score was calculated through receiver operating characteristic (ROC) curve analysis, further dividing patients into high-risk group (HRG) and low-risk group (LRG), and comparing the short to midterm postoperative outcomes between the two groups. In the end, a total of 158 cases (28.9%) experienced PIS. Through LASSO regression analysis and multivariable logistic regression analysis, variables including age, emergency surgery, operative time, contrast medium volume, and number of main prosthesis stents were selected to construct the nomogram predictive model. The model achieved an area under the curve (AUC) of 0.86 in the training set and 0.82 in the test set. Results from calibration curve, decision curve analysis (DCA) and clinical impact curve (CIC) demonstrated that the predictive model exhibited good performance and clinical utility. Furthermore, after comparing the postoperative outcomes of HRG and LRG patients, we found that the incidence of postoperative PIS significantly increased in HRG patients. The duration of ICU stay and mechanical assistance time was prolonged, and the incidence of postoperative type II entry flow and acute kidney injury (AKI) was higher. The risk of aortic-related adverse events (ARAEs) and major adverse events (MAEs) at the first and twelfth months of follow-up also significantly increased. However, there was no significant difference in the mortality rate during hospitalization. This study established a nomogram model for predicting the risk of PIS in patients with TBAD undergoing TEVAR. It serves as a practical tool to assist clinicians in early risk stratification and decision-making management for patients.

Thoracic Endovascular Repair after Total Aortic Arch Replacement with Frozen Elephant Trunk for Type a Aortic Dissection. Ann Vasc Surg 2024; 99:290-297. [PMID: 37858671 DOI: 10.1016/j.avsg.2023.08.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 08/12/2023] [Accepted: 08/17/2023] [Indexed: 10/21/2023]
Abstract
BACKGROUND The management of residual aortic dissection after initial type A repair with the Frozen elephant trunk technique remains mostly unexplored. This work aimed to evaluate endovascular second-stage surgery for patients with residual aortic dissection. METHODS A retrospective analysis of consecutive patients that underwent Type A aortic repair with Frozen elephant trunk, followed by a second-stage endovascular procedure was done from March 2016 to December 2021. The primary outcome was aortic-related adverse events or mortality, and secondary outcomes were aortic remodeling and perioperative complications. Remodeling was assessed by comparing the difference in ratios for true lumen/total aortic diameters on pre-operative and follow-up scans. RESULTS Thirty-four patients underwent second-stage surgery after Type A repair during the study period (7 thoracic endovascular aortic repair extensions, 1 STABLE/PETTICOAT, and 26 STABILISE). Median follow-up was 23 months (range 2-66 months). There were no perioperative deaths or major complications and 1 reoperation for left subclavian re-embolization. At the last follow-up, there was no aortic-related mortality. There were 5 aortic-related adverse events, including another subclavian re-embolization and a preplanned open conversion. Risk factors were connective tissue disorders (P = 0.01) and aortic aneurysms >55 mm (P = 0.03). Distal remodeling reached statistical significance in all segments (P < 0.01) and was greater for patients treated with the STABILISE technique when compared to extended thoracic endovascular aortic repair (P = 0.01). CONCLUSIONS Second-stage endovascular management of residual aortic dissection after initial Frozen elephant trunk repair showed excellent perioperative and good midterm outcomes and induced significant remodeling of the entire aorta in most cases, particularly with the STABILISE procedure.

[PMID: 37425476 PMCID: PMC10328807 DOI: 10.1016/j.xjon.2023.02.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/20/2022] [Revised: 02/14/2023] [Accepted: 02/28/2023] [Indexed: 07/11/2023]
Abstract
Objective Antithrombotic therapy has the potential to interfere with false lumen thrombosis. In type B acute aortic syndrome, the degree of false lumen thrombosis affects clinical outcomes. We aimed to explore the association of antithrombotic therapy with the prognosis of patients with type B acute aortic syndrome. Methods We reviewed 406 patients with type B acute aortic syndrome who were discharged alive with and without antithrombotic therapy. The primary outcome was aorta-related adverse events, defined as a composite of aorta-related death, aortic rupture, aortic repair, and progressive aortic dilation. Results Of the 406 patients, 64 (16%) were discharged with antithrombotic therapy and 342 (84%) were discharged without antithrombotic therapy. A total of 249 patients (61%) presented with intramural hematoma with complete thrombosis of the false lumen, and 157 patients (39%) presented with aortic dissection. During a median follow-up of 4.6 years, 32 patients (50%) in the antithrombotic group and 93 patients (27%) in the nonantithrombotic group had a primary outcome event. Cumulative incidence of aorta-related events at 1 and 3 years with death as the competing risk was higher in the antithrombotic group than in the nonantithrombotic group (19% ± 5% vs 9% ± 2% at 1 year and 40% ± 7% vs 17% ± 2% at 3 years, P < .001). Conclusions Antithrombotic therapy might be associated with an increased risk of aorta-related events in patients with type B acute aortic syndrome.

Abstract
Chronic type B aortic dissection (cTBAD) is a rare but challenging condition that requires individual treatment strategies. Especially the long-term therapy impacts prognosis. In this single-center retrospective study, we evaluated patients with cTBAD in our vascular outpatient clinic over 10 years. Follow-up consultations included contrast-enhanced, electrocardiogram-triggered, high-resolution CT angiography (CTA) covering the entire aorta. Evaluated characteristics went beyond demographic characteristics combining the treatment approach and the timing and occurrence of potential complications. We analyzed 133 patients in total (n = 92, 69.2% male) with cTBAD with a mean follow-up of 67.7 months. Most of them underwent invasive treatment (n = 102, 76.7%), the majority received thoracic endovascular aortic repair (TEVAR) (n = 82, 61.7%). A total of 80 patients (60.2%) had major complications, whereas over a third was free of complications even after 5 years. Most common complications were progress of dissection and endoleaks, aneurysms of true (TL) and false lumen (FL) were more common in the later time periods. The treatment of cTBAD in terms of timing, therapy approach, and complications is still challenging for the entire aortic team. Nevertheless, the early recognition of complications permits promising treatment options and highlights the importance of frequent follow-up examinations especially within the first years.

Monitoring of false lumen thrombosis in type B aortic dissection by impedance cardiography - A multiphysics simulation study. INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN BIOMEDICAL ENGINEERING 2023; 39:e3669.

Abstract
Aortic dissection is caused by a tear on the aortic wall that allows blood to flow through the wall layers. Usually, this tear involves the intimal and partly the medial layer of the aortic wall. As a result, a new false lumen develops besides the original aorta, denoted then as the true lumen. The local hemodynamic conditions such as flow disturbances, recirculations and low wall shear stress may cause thrombus formation and growth in the false lumen. Since the false lumen status is a significant predictor for late-dissection-related deaths, it is of great importance in the medical management of patients with aortic dissection. The hemodynamic changes in the aorta also alter the electrical conductivity of blood. Since the blood is much more conductive than other tissues in the body, such changes can be identified with non-invasive methods such as impedance cardiography. Therefore, in this study, the capability of impedance cardiography in monitoring thrombosis in the false lumen is studied by multiphysics simulations to assist clinicians in the medical management of patients under treatment. To tackle this problem, a 3D computational fluid dynamics simulation has been set up to model thrombosis in the false lumen and its impact on the blood flow-induced conductivity changes. The electrical conductivity changes of blood have been assigned as material properties of the blood-filled aorta in a 3D finite element electric simulation model to investigate the impact of conductivity changes on the measured impedance from the body's surface. The results show remarkable changes in the electrical conductivity distribution in the measurement region due to thrombosis in the false lumen, which significantly impacts the morphology of the impedance cardiogram. Thus, frequent monitoring of impedance cardiography signals may allow tracking the thrombus formation and growth in the false lumen.

Abstract
OBJECTIVE Most of the entry tears of uncomplicated type B aortic dissection are located in the distal arch and extends in a retrograde manner to the level of the left subclavian artery. Our objective was to evaluate feasibility and effectiveness using fenestrated sent graft with complete neck vessel preservation to treat uncomplicated type B aortic dissection. SUBJECTS AND METHODS We retrospectively reviewed the record of patients with uncomplicated type B aortic dissection who underwent fenestrated thoracic endovascular aortic repair in subacute phase (15-90 days) between August 2016 and April 2020. The Najuta fenestrated stent graft was placed proximally beyond he left subclavian artery (zone 0-2) in an attempt to seal the entry while preserving the neck vessels. RESULTS We evaluated 9 cases (male: 7, female: 2; median age 70 years). The median distance from the LSA to the proximal entry was 37 mm. The landing zones of the proximal end of the Najuta were zone 0: 3, zone 1: 2, and zone 2: 4 cases. Technical success was 100% with no 30-day death. None of the patients had a stroke, paraplegia or retrograde dissection, and no endoleak was observed. Complete aortic remodeling with false lumen resolution was obtained in all cases while each fenestrated vessels remained patent during the follow-up period. CONCLUSION Preemptive thoracic endovascular aortic repair aimed at perfusion of cervical branches using the Najuta fenestrated stent is safe and effective and may be considered as a reasonable treatment option for the treatment is a safe and an effective treatment.

Abstract
BACKGROUND Chronic type B aortic dissection requires optimal medical therapy. However, secondary complications like organ or extremity malperfusion or development of aneurysmal dilatation require interventional therapy. OBJECTIVES Presentation of different endovascular treatment options for complications of chronic type B aortic dissection. MATERIALS AND METHODS Analysis of current literature with regard to indications, techniques, results, and differential indications of interventional techniques for the treatment of chronic type B aortic dissection complications. RESULTS Endovascular implantation of an aortic stent graft is interventional standard therapy for treatment of aneurysmal dilatation of the aorta following type B dissection. Technical problems are the proximal and distal landing zones and the treatment of persistent flow in the false lumen. CONCLUSION Endovascular treatment of chronic complicated type B aortic dissection is increasingly used compared to open surgical treatment because not only are more complex stent grafts (fenestrated and branched devices) available but also because of newly developed techniques for effective occlusion of flow in the false lumen (e.g., candy plug).

Abstract
Objective:The standard treatment for complicated Stanford type B aortic dissection (TBAD) is thoracic endovascular aortic repair (TEVAR). Functional parameters, specifically blood flow, are not measured in the clinical assessment of TEVAR, yet they are of outmost importance in patient outcome. Consequently, we investigated the impact of TEVAR on the flows in the aorta and its branches in TBAD using 4D Phase-Contrast Magnetic Resonance Imaging (4D Flow MRI).MethodsSeven patients with TBAD scheduled for TEVAR underwent pre and post-operative 4D Flow MRI. An experienced reader assessed the presence of helical flow in the false lumen (FL) using streamlines and measured net flow at specific locations. In addition, forward and reverse flows, stasis, helicity, and absolute helicity were computed automatically along the aorta centerline. Average values were then computed in the segmented vessels. Impact of TEVAR on these parameters was assessed with a Wilcoxon signed rank test. Impact of the metallic stent on the velocity quantification was assessed using intra-class correlation coefficient (ICC) between velocities measured intra-stent and in adjacent stent-free regions.ResultsFL helical flow was observed proximally in 6 cases and distally in 2 cases pre-operatively. Helical flow disappeared post-TEVAR proximally, but developed distally for 2 patients. Intra-stent measures were similar to stent-free with a median difference of 0.1 L/min and an ICC equal to 0.967 (p < 0.01). Forward flow increased from 59.9 to 81.6% in the TL and significantly decreased in the FL from 15.9 to 3.3%. Similarly, reverse flow increased in the TL from 4.36 to 10.8% and decreased in the FL from 10.3 to 4.6%. No significant changes were observed in net flow for aortic branches (p > 0.05). A significant increase in FL stasis was observed (p = 0.04).DiscussionTEVAR significantly increased forward flow in the TL and significantly decreased both forward and reverse flows in the FL. Interestingly, reverse flow in the TL increased post-TEVAR, which could be due to increased rigidity of the wall, due to the metallic stent. User independent helicity quantification enabled detection of elevated helicity at the level of secondary entry tears which had been missed by streamline visualization.

Abstract
Background To characterize the difference in aortic dimensions during the cardiac cycle with electrocardiogram (ECG)-gated computed tomography angiography (CTA) and to determine whether other parameters in comparison to diameter could potentially provide a more accurate size reference for stent selection at the aortic arch and the proximal thoracic descending aorta. Methods The CTA imaging of 90 patients during the cardiac cycle was reviewed. Three anatomic locations were selected for analysis (level A: 1 cm proximal to the innominate artery; level B: 1 cm distal to the left common carotid artery; and level C: 1 cm distal to the left subclavian artery). We measured the maximum diameter, the minimum diameter, the lumen area, the lumen perimeter, and the diameter derived from the lumen area, and the changes of each parameter at each level during the cardiac cycle were compared. Results The mean age was 60.9 ± 12.4 years (range, 16–78 years). There was a significant difference in the aortic dimensions during the cardiac cycle (p < 0.001). The diameter derived from the lumen area at all three levels was changed least over time when compared to the area, perimeter, and the maximum aortic diameter (all p < 0.01). Conclusion The aortic dimensional differences during the cardiac cycle are significant. The aortic diameter derived from the lumen area over other parameters may provide a better evaluation for selecting the size of the stent at the aortic arch and the proximal thoracic descending aorta. A prospective study comparing these different measurement parameters regarding the outcomes is still needed to evaluate the clinical implications.

Abstract
Non-traumatic thoracic aorta emergencies are associated with significant morbidity and mortality. Diseases of the intimomedial layers (aortic dissection and variants) have been grouped under the common term of acute aortic syndrome because they are life-threatening conditions clinically indistinguishable on presentation. Patients with aortic dissection may present with a wide variety of symptoms secondary to the pattern of dissection and end organ malperfusion. Other conditions may be seen in patients with acute symptoms, including ruptured and unstable thoracic aortic aneurysm, iatrogenic or infective pseudoaneurysms, aortic fistula, acute aortic thrombus/occlusive disease, and vasculitis. Imaging plays a pivotal role in the patient’s management and care. In the emergency room, chest X-ray is the initial imaging test offering a screening evaluation for alternative common differential diagnoses and a preliminary assessment of the mediastinal dimensions. State-of-the-art multidetector computed tomography angiography (CTA) provides a widely available, rapid, replicable, noninvasive diagnostic imaging with sensitivity approaching 100%. It is an impressive tool in decision-making process with a deep impact on treatment including endovascular or open surgical or conservative treatment. Radiologists must be familiar with the spectrum of these entities to help triage patients appropriately and efficiently. Understanding the imaging findings and proper measurement techniques allow the radiologist to suggest the most appropriate next management step.

Obstructive Sleep Apnoea in Stanford Type B Aortic Dissection Is Associated With Multiple Imaging Signs Related to Late Aortic Events. Front Cardiovasc Med 2021; 8:752763. [PMID: 34869658 PMCID: PMC8636812 DOI: 10.3389/fcvm.2021.752763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 10/25/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Obstructive sleep apnoea (OSA) is highly prevalent in patients with Stanford type B aortic dissection (TBAD). Few studies have evaluated the effects of OSA on vascular changes in TBAD patients. This study aimed to explore the effect of OSA on aortic morphological changes in TBAD patients and its relation to late aortic events (LAEs). Methods: This case-control study included 143 TBAD patients. The diameters of different parts of the aorta were measured based on computed tomography angiography (CTA). According to the apnoea-hypopnoea index (AHI), OSA was classified as mild (5 ≤ AHI ≤ 15), moderate (15 < AHI ≤ 30), or severe (AHI > 30). The false lumen (FL) status was evaluated and classified as partially thrombosed, patent, or completely thrombosed. Results: The OSA prevalence in TBAD patients was 64.3%, and image differences related to LAEs between TBAD patients with and without OSA included the maximum aortic diameter at onset (37.3 ± 3.9 vs. 40.3 ± 4.5 mm, p < 0.001), the FL diameter of the proximal descending thoracic aorta (16.0 ± 6.8 vs. 20.3 ± 4.7 mm, p < 0.001), and the proportion of the FL that was partially thrombosed (39.2 vs. 64.1%, p = 0.004). Additionally, in the multivariable analysis of patients with OSA, the risks of an aortic diameter ≥40 mm, a proximal descending aorta FL ≥ 22 mm and a partially thrombosed FL were 4.611 (95% CI: 1.796–11.838, p = 0.001), 2.544 (95% CI: 1.050–6.165, p = 0.039), and 2.565 (95% CI: 1.167–5.637, p = 0.019), respectively, after adjustment for confounding factors. Trend tests showed that the risks of an aortic diameter ≥40 mm and a partially thrombosed FL increased with increasing OSA severity. Conclusions: TBAD patients with moderate to severe OSA have aortic dilatation in different parts of the aorta. OSA is an independent risk factor for multiple imaging signs related to LAEs, suggesting that OSA is an important factor affecting the prognosis of TBAD patients.

Abstract
OBJECTIVES Thoracic endovascular aortic repair (TEVAR) has become first line therapy for complicated acute type B aortic dissection (aTBAD). However, the strategy for optimal proximal landing zone remains to be determined. We compared early outcomes and late aortic-related adverse events in patients undergoing TEVAR for complicated aTBAD with endograft deployment in proximal landing zone 2 versus 3. METHODS We performed a retrospective chart review of adult patients undergoing TEVAR for complicated aTBAD within 6 weeks of diagnosis from 1/2008 to 12/2018. We excluded patients with connective tissue disorders and prior type A repair. Patients were divided into landing zone 2 TEVAR (Z2T) and zone 3 TEVAR (Z3T) groups. Z2 patients were divided between left subclavian artery (LSA) revascularization (Z2R) versus LSA coverage without revascularization (Z2C). Groups were compared for need for aortic re-intervention within 36 months of initial admission and freedom from aortic related adverse events and mortality (AREM), defined as need for aortic re-intervention, aortic-related death or rupture. RESULTS Eighty-three patients underwent TEVAR for complicated aTBAD within a mean of 4.1±7.8 days. 89.5% of patients had less than 2 cm of healthy proximal descending thoracic aorta. Landing zone was Z3T in 35 patients and 48 underwent Z2T: 10 Z2C and 38 Z2R. There were no differences between Z2T and Z3T in time from diagnosis to TEVAR, demographics, comorbidities and diameter aortic measurements. 30-day survival was 87.8%: 89.5% for Z2R, 88.6% for Z3 and 80.0 % for Z2C (p=0.610). Post-operative spinal cord ischemia rate was 3.7%: 2.7 % for Z2R, 0% for Z3T and 20.0% for Z2C (p=0.012). Post-operative thoracic aortic rupture was 2.2% in Z2 and 0 in Z3. Need for aortic re-intervention at 36 months post-TEVAR was lower for Z2T (10.4%) vs. Z3T (31.4%), p=0.025. Freedom from AREM at 36 months was higher in Z2T vs. Z3T - 87.5% vs. 68.6%, p= 0.048. Freedom from proximal re-intervention was higher in Z2T (95.8%) compared to Z3T (80.0%), p=0.019. Z3T deployment was predictive for AREM (OR:3.648,95%CI:1.161-11.465,p=0.027) and need for proximal re-intervention (OR: 5.542,95%CI:1.062-28.927,p=0.042). CONCLUSION Most patients with aTBAD have less than 2 cm of proximal healthy descending thoracic aorta. In patients treated for complicated aTBAD, zone 2 TEVAR is associated with a lower need for aortic re-intervention and aortic-related adverse events than zone 3 TEVAR. Patients may benefit from a more aggressive proximal landing zone with similar perioperative morbidity when zone 2 TEVAR is done with LSA revascularization.

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

Abstract
INTRODUCTION The conservative management of a Stanford type B aortic dissection (TBD) is optimal blood pressure management, cardiac rehabilitation, and progressive return to activities of daily living (ADL) while preventing advancing dissection and aortic dilation. Recent case reports indicate higher levels of activity may be safe; however, the exercise parameters for chronic TBD conditions span a broad range and the research is limited. CASE PRESENTATION The clinical presentation and outpatient cardiac and physical rehabilitation program for a 61-year-old male with a chronic TBD from his subclavian artery to common iliac arteries is presented. The exercise protocol was developed and based on the available literature for the management of chronic aortic diseases. Eighteen months after the patient's acute TBD event, he began an exercise protocol designed to address the sport specific functional deficits related to his recreational activities. The program incorporated a variety of exercises from resistance training to cardiovascular exercise and high interval training. The therapeutic goals included restoration of cardiac fitness and improvement of core stability and appendicular strength, ultimately aiming toward a potential to return to recreational sport involving short duration, high intensity activity. CONCLUSION In conjunction with the appropriate anti-hypertensive medication treatment, understanding the concepts of aortic hemodynamics as they relate to exercise can serve as a guideline for clinicians in developing an individualized exercise program for their TBD patients. Moreover, these physical training programs may include particular exercise guidelines beyond general recommendations of light to moderate cardiovascular activities.

Abstract
OBJECTIVE Thoracic aortic dissection (TAD) is associated with matrix changes, biochemical changes, and inflammatory markers like interleukin-1 beta (IL-1β). However, the exact mechanism remains unknown. This study aimed to investigate the role of IL-1β, matrix metalloproteinase (MMP)-2, MMP-9, smooth muscle cell apoptosis, and elastic fibre fracture in the development of TAD in a rat model. METHODS The TAD rat model was induced by β-aminopropionitrile (BAPN). TAD was investigated in 112 male Sprague-Dawley rats, which were equally divided into four groups of 28 rats (Control, BAPN, BAPN + IL-1β, and BAPN + IL-1β antibody). Systolic blood pressure, survival, and the development of TAD were measured after six weeks. Expression of IL-1β, MMP-2, and MMP-9 was measured by Western blot. Apoptosis, aortic elastin concentration, and biomechanical characteristics were measured by the TdT mediated dUTP nick end labelling assay, Victoria blue staining, and in vitro testing. RESULTS During six weeks, the mortality was 0% (0/28) in the control group, 53.6% (15/28) in the BAPN group (p < .001 compared with the control group), 75.0% (21/28) in the BAPN + IL-1β group (p = .007 compared with the BAPN group), and 35.7% (10/28) in the BAPN + IL-1β antibody group (p = .023 compared with BAPN group and p < .001 compared with the BAPN + IL-1β group). IL-1β treatment deteriorates BAPN induced mortality and aneurysm expansion, which were attenuated by anti-IL-1β treatment. In BAPN + IL-1β group, stress and strain parameters were decreased by 13.5%-53.5% and elastin content was decreased by 14%, and IL-1β, MMP-2, and MMP-9 were expressed higher by 117%, 108%, and 75% when compared with the rats in the BAPN group. Contrarily, in the BAPN + IL-1β antibody group, the above changes could be completely (strain, elastin content, and expression of MMP-2) or partly (elasticity modulus, stress, and expression of MMP-9) blocked by anti-IL-1β treatment. CONCLUSION IL-1β plays a critical role in TAD formation by altering the expression of MMP-2 and MMP-9, degrading the aortic wall matrix, causing elastic fibre rupture, and changing the stress or strain of the aortic wall. Anti-IL-1β reduces the later effects and could be one of the molecular targets for prognosis and drug treatment of TAD in the future.

Abstract
In recent guidelines of international societies, the most frequent indication for treatment after chronic type B aortic dissection (cTBAD) is aneurysmal dilatation. Endovascular repair is recommended in patients with moderate to high surgical risk or with contraindications to open repair. During the last decade, many advances have been made in the field of endovascular techniques and devices. The aim of this article is to address the current status of endoluminal techniques for the management of cTBAD including standard thoracic endovascular repair, new devices, fenestrated and branched abdominal aortic devices and false lumen occlusion techniques.

Abstract
OBJECTIVE The aim of this study was to determine geometric changes in the proximal and distal aortic landing zones after thoracic endovascular aortic repair (TEVAR) for acute descending aortic dissection. METHODS This was a retrospective analysis of clinical and radiological data. Included are patients who underwent TEVAR for acute descending aortic dissection between 2004 and 2018. Analysed are the proximal and distal landing zones' initial geometries and their change at follow up. Median follow up time was 2.3 (first quartile 0.9, third quartile 4.5) years. RESULTS One hundred and one patients were included (93 type B and 8 non-A non-B dissections, aged 65 (57, 74) years old, and 29% female). Dissection extended down to the abdominal aorta in 69% patients. The proximal landing zone was non-dissected in 92 patients. The diameters of non-dissected proximal landing zones increased by 3 (-1, 5; p < .001) mm at follow up. The distal landing zone was dissected in 84% of patients. The diameters of dissected distal landing zones had increased at follow up by 7 (3, 12) mm and 4 (1, 10; both p < .001) mm measured in true lumen and total aorta, respectively, observed one year after TEVAR. Stent grafts reached their nominal diameter at follow up in 22% and 17% of proximal and distal landing zones, respectively. There were seven proximal and 10 distal stent graft induced new entries at follow up. Aortic re-intervention was necessary in 23 patients entailing 19 TEVAR extensions and four open aortic repairs. CONCLUSION The distal landing zone in patients undergoing TEVAR for descending aortic dissection is frequently dissected and is associated with the risk of d-SINE at follow up and the need for re-interventions after TEVAR - factors that emphasise the importance of long term follow up.

Abstract
The natural course of intramural hematoma (IMH) of the aorta remains unpredictable and despite an increasing amount of literature reports its treatment is still debatable. IMH typically is diagnosed by computed tomography that has permitted to identify specific images whose onset, in uncomplicated cases, appears to be associated to a dismal prognosis. We report on a case series of acute uncomplicated type B IMH in which early detection of such findings, given the expected poor prognosis associated to the aorta-related mortality, suggests the need to shift toward an aggressive endovascular aortic repair in this subset of patients.

Abstract
Purpose To compare hybrid and in vitro fenestration procedures for preserving the left subclavian artery in thoracic endovascular aortic repair (TEVAR) with unfavorable proximal landing zone. Methods Retrospective comparison of data from 49 consecutive patients who underwent left subclavian artery revascularization during TEVAR by either hybrid or fenestration approaches from January 2015 to March 2018. Procedural duration, and 30-day rates of procedural success, mortality and complications (endoleaks, cerebral infarction, spinal cord ischemia, left arm ischemic symptoms, and delirium) were compared. Results For hybrid procedure ( n = 32) vs. fenestration ( n = 17) groups, which were age and gender matched: procedural success rate was 100%, with significantly longer procedural duration (248.4 ± 40.9 vs. 60.6 ± 16.8 min; t = –22.653, P = 0.000) and similar 30-day complication rate (18.8% vs. 11.8%; χ2 = 0.397, P = 0.529). At 12.7 ± 9.3 months’ follow-up, there were no cases of death, spinal cord ischemia, or other complications in either group. Conclusions In this retrospective, single-center comparison, both hybrid and in vitro fenestration approaches for reconstructing the left subclavian artery in TEVAR with unfavorable proximal landing zone appeared safe and effective, with shorter procedural duration for fenestration. Larger studies with longer term follow-up are warranted.

Abstract
OBJECTIVE To investigate the effect of bilateral superior cervical sympathetic ganglion occlusion (SCG) on aortic dissection and its possible mechanism. METHODS Forty-five SD rats were randomly divided into three groups with 15 in each:blank control group, sham operation group and SCG group. β-aminopropione (666 mg·kg-1·d-1) was given by subcutaneous injection for 4 weeks to establish the aortic dissection model. Rats in SCG group were given SCG before the injection of β-aminopropione. Blood pressure and heart rate of the rats were monitored using noninvasive tail artery blood pressure measuring instrument; sympathetic activity was monitored using drug block method; the structure of aortic wall was observed using HE staining; collagen fibers in aortic wall was observed using Sirius red staining; protein expression of Apelin was detected by immunohistochemistry; and the protein expression of matrix metalloproteinase (MMP)-2, 9 was detected by Western blotting. RESULTS During the experiment, the body mass of the sham operation group and SCG group was smaller than that of the blank control group (all P<0.05), and the body mass of the SCG group was larger than that of the sham operation group (all P<0.05). The heart rate and sympathetic activity of the sham operation group were higher than those of the blank control group (all P<0.05), while the SCG group were lower (all P<0.05). Compared with the blank control group, the aortic wall in the sham operation group was thickening, while that in the SCG group was improved. A large number of collagen-1 in the aortic wall of the blank control group was stained brown by Sirius red, which was lighter in SCG group, and the staining in the sham operation group was the lightest. Compared with the blank control group, the expression of Apelin, MMP-2 and MMP-9 protein in the sham operation group increased (all P<0.05), while those in the SCG group decreased (all P<0.05). CONCLUSIONS SCG can effectively reduce the incidence and mortality of aortic dissection in rats, which may be related to the inhibition of sympathetic activity and the decrease of collagen-1, Apelin, MMP-2 and MMP-9 expression.

Abstract
OBJECTIVES: Patients with chronic aortic dissection often require repeat interventions due to enlargement of the pressurized false lumen or disseminated intravascular coagulation even after additional thoracic endovascular aortic repair (TEVAR) to occlude the entry tear. Residual false lumen flow can persist even after performing the candy-plug technique or branched stent-graft placement in some cases. We have devised a new method for false lumen closure. METHODS: From December 2010 to May 2017, 5 patients (mean age: 57 [13] years, range: 43-77 years) with chronic dissection at the aortic arch and descending aorta, who underwent initial TEVAR, required additional treatment. Using an open surgical approach, the endograft was fixed with an outer felt under cardiopulmonary bypass after the endograft with stent was expanded by fenestration. The false lumen was closed using this procedure, and the aortotomy was repaired by direct closure in 2 cases and by graft replacement in 3 cases. RESULTS: No major operative complications occurred, such as respiratory failure or paraplegia. Postoperative enhanced computed tomography (CT) images showed that the false lumen flow disappeared in all cases. All patients were discharged under normal conditions. They were all followed up and their CT did not indicate any complications for a mean of 33.6 (20.3) months. CONCLUSIONS: Our combined procedure was effective and provided a higher success rate compared with endovascular therapy alone. This staged treatment approach, using a combination of TEVAR and false lumen closure, is less invasive compared with open surgery alone and may represent a valid treatment option for chronic type B dissection.
