    提出一种新颖的技术,该技术能够在开窗/分支血管内主动脉修复(F/B-EVAR)期间以具有挑战性的解剖结构对目标血管进行安全有效的插管。
    展开F/B-EVAR内移植物后,目标血管(电视)是插管。束线技术为具有挑战性的电视提供了解决方案,并使用了多个精细的无创伤导丝,这些导丝一起用作刚性导丝。该技术可以使用以下两种方式执行:(1)一根0.018英寸和一根0.014英寸导丝或(2)三根0.014英寸导丝。我们在使用分支EVAR治疗的复杂腹主动脉瘤的情况下证明了该技术,其中使用束线技术将患有严重口狭窄的左肾动脉插入导管。
    束线技术提供了一种技术上可行且经济上可行的解决方案,用于在F/B-EVAR期间在解剖学上具有挑战性的电视中促进导管和桥接支架的输送。它是医生可用于访问要求苛刻的电视的治疗性医疗设备的有用补充。
    UNASSIGNED: To present a novel technique that enables safe and effective cannulation of target vessels with challenging anatomy during fenestrated/branched endovascular aortic repair (F/B-EVAR).
    UNASSIGNED: Following deployment of the F/B-EVAR endograft, the target vessels (TVs) are cannulated. The bundle wire technique provides a solution to challenging TVs and uses multiple fine atraumatic guidewires that together serve as a stiff guidewire. The technique can be executed in 2 ways using: (1) one 0.018 inch and one 0.014 inch guidewire or (2) three 0.014 inch guidewires. We demonstrate the technique in a case of a complex abdominal aortic aneurysm treated using branched EVAR in which the left renal artery with severe ostial stenosis was catheterized using the bundle wire technique.
    UNASSIGNED: The bundle wire technique offers a technically feasible and economically viable solution for facilitating catheter and bridging stent delivery in anatomically challenging TVs during F/B-EVAR. It is a useful addition to the therapeutic armamentarium available to physicians for accessing demanding TVs.

    主动脉疾病,比如主动脉瘤,解剖,和破裂,在临床急症中占很大比例。红细胞分布宽度(RDW),这直接反映了红细胞增多症(即,红细胞体积的异质性),已经成为许多心血管疾病的有希望的生物标志物。因此,我们旨在探讨RDW在主动脉病变中的意义。我们使用关键字\"RDW\"或\"红细胞分布宽度\"和\"主动脉瘤\"或\"主动脉扩张\"或\"主动脉夹层\"搜索Scopus和PubMed,以确定在这些主动脉疾病患者中测量RDW值的研究。最终纳入了10项观察性研究。在所有研究中,主动脉疾病患者的RDW值升高。在有足够的RDW数据可用于汇集的四项研究中,在有或无复杂主动脉病变的患者中,RDW的加权平均差值(WMD)为0.575(95CI,0.254~0.896).RDW可能是主动脉病变患者的有价值的诊断和预后生物标志物。
    Diseases of the aorta, such as aortic aneurysm, dissection, and rupture, account for a large proportion of acute clinical emergencies. The red blood cell distribution width (RDW), which directly reflects anisocytosis (i.e., the heterogeneity of erythrocyte volumes), has emerged as a promising biomarker for many cardiovascular pathologies. Thus, we aimed to explore the implication of RDW in aortic pathologies. We searched Scopus and PubMed using the keywords \"RDW\" OR \"red blood cell distribution width\" AND \"aortic aneurysm\" OR \"aortic dilatation\" OR \"aortic dissection\" for identifying studies in which RDW values were measured in patients with these aortic diseases. Ten observational studies were finally included. In all studies, RDW value was increased in patients with aortic diseases. In the four studies in which sufficient RDW data were available for pooling, the weighted mean difference (WMD) of RDW in patients with or without complicated aortic pathologies was 0.575 (95 %CI, 0.254-0.896). RDW may be a valuable diagnostic and prognostic biomarker in patients with aortic pathologies.

    方法:由于文献证据不足,经肱动脉入路(TBA)的机械血栓切除术(MT)在主动脉病变和急性缺血性卒中(AIS)的患者中非常罕见。从技术角度来看的困难和该技术的结果受到经常伴随它的并发症的影响。
    背景:文献中仅报道了少数主动脉病变和急性缺血性卒中患者通过TBA进行MT,在AIS应急管理中的应用还没有详细的论述。
    目的:出于澄清和明确强调这种方法在AIS和主动脉病变患者中通过TBA进行急诊MT的有效性的需要,本文献回顾和病例报告具有以下目的:第一个是在44岁的AIS患者中通过经肱动脉入路进行的急诊MT,并在经股动脉入路(TFA)期间被诊断为主动脉缩窄,在我们部门成功进行再灌注,第二个是回顾文献中MT通过TBA进行的不同主动脉病理和AIS再灌注治疗的患者的病例报告。
    方法:总共9例(1例个人病例和8例发表病例)根据主动脉病理类型进行了修订,再灌注治疗类型,以及机械取栓和局部经臂入路的并发症。
    结果:在超过一半的病例中,通过经臂入路的机械血栓切除术是首选(55.55%,n=5例)在先前诊断为主动脉病变的情况下治疗急性缺血性中风。在所有病例的三分之一(33.33%,n=3,我们的病例和2例文献报告),在尝试推进引导导管通过经股动脉入路和术中主动脉病理诊断后,选择经肱动脉入路.只有一种情况,在对显示单相血流的桡动脉进行超声评估后,MT通过TBA进行。报告1例经肱局部并发症,在另外两种情况下,没有说明是否有这种并发症。据报道,有2例通过TBA进行仅MT脑再灌注的AIS出血性转化,1例急性主动脉夹层A型和我们以前未诊断的主动脉缩窄病例。在报告了短期和长期随访的病例中,治疗的结果,这并非完全是血管内(77.77%的病例仅有MT,33.33%的病例与首次溶栓和MT后相关),很好(9名患者中有6名)。在两个案例报告中,结果没有说明,一名患者在重症监护病房长期住院后死于呼吸系统并发症(我们的患者)。
    结论:作为临床紧急情况,急性缺血性卒中需要紧急医疗干预.在主动脉病变患者中,急性缺血性卒中的急诊护理是一个挑战,经臂入路机械取栓是脑再灌注的安全替代方法。
    METHODS: Mechanical thrombectomy (MT) via the transbrachial approach (TBA) is a very rare option used in cases of patients with aortic pathologies and acute ischemic stroke (AIS) due to the insufficient evidence in the literature, the difficulty from a technical point of view and the result of this technique influenced by the complications that frequently accompany it.
    BACKGROUND: Only a few cases of patients with aortic pathologies and acute ischemic stroke where MT via TBA were reported in the literature, and its application in the emergency management of AIS has still not been dealt with in detail.
    OBJECTIVE: Out of a need to clarify and clearly emphasize the effectiveness of this approach in emergency MT via TBA in patients with AIS and aortic pathologies, this literature review and case report has the following objectives: the first one is the presentation of an emergency MT via transbrachial approach performed in a 44-year-old patient with AIS and diagnosed aortic coarctation during transfemural approach (TFA), with successful reperfusion in our department and the second one is to review the cases reports of patients with different aortic pathologies and AIS reperfusion therapy performed by MT via TBA from the literature.
    METHODS: A total of nine cases (one personal case and eight published cases) were revised in terms of aortic pathologies type, reperfusion therapy type, and the complication of both mechanical thrombectomy and local transbrachial approach.
    RESULTS: Mechanical thrombectomy through the transbrachial approach was the first choice in more than half of these cases (55.55%, n = 5 cases) in the treatment of acute ischemic stroke in the presence of previously diagnosed aortic pathologies. In one-third of all cases (33.33%, n = 3, our case and 2 case reports from the literature), the transbrachial approach was chosen after attempting to advance the guiding catheter through the transfemoral approach and intraprocedural diagnosis of aortic pathology. In only one case, after an ultrasound evaluation of the radial artery that showed a monophasic flow, MT was performed via TBA. Local transbrachial complication was reported in one case, and in two other cases, it was not stated if there were such complications. Hemorrhagic transformation of AIS was reported in two cases that underwent MT-only cerebral reperfusion via TBA, one with acute aortic dissection type A and our case of previously undiagnosed aortic coarctation. In the cases in whom short and long-term follow-up was reported, the outcome of treatment, which was not exclusively endovascular (77.77% cases with only MT and 33.33% with association of first thrombolysis and after MT), was good (six from nine patients). In two case reports, the outcomes were not stated, and one patient died after a long hospitalization in the intensive care unit from respiratory complications (our patient).
    CONCLUSIONS: Being a clinical emergency, acute ischemic stroke requires urgent medical intervention. In patients with aortic pathologies, where acute ischemic stroke emergency care is a challenge, mechanical thrombectomy via the transbrachial approach is a safe alternative method for cerebral reperfusion.

    背景:内皮细胞层对于维持各种血管功能至关重要。导致主动脉病变如腹主动脉瘤(AAA)和主动脉夹层(AD)的内皮功能障碍的主要危险因素包括吸烟和高血压。本研究探讨了尼古丁(Nic)和血管紧张素II(AngII)在转录水平上对人主动脉内皮细胞(HAoECs)的影响。
    方法:将HAoEC暴露于100nM的Nic和/或100nM的AngII。在暴露后进行RNA测序(RNA-Seq)以鉴定受调节的基因。应用RT-qPCR验证结果。GeneMANIA用于进行计算机分析,旨在鉴定炎症中潜在的下游相互作用基因,细胞粘附,内皮细胞增殖,和凝血途径。
    结果:RNA-Seq鉴定LGALS9(半乳糖凝集素-9)在Nic暴露后可能受到调节,而随后的RT-qPCR实验证实了转录调控(p<0.05)。随后的计算机模拟分析鉴定了与不同基因组中的LGALS9相互作用的潜在候选基因。在可能与LGALS9相互作用的前100个基因中,有18个是炎症反应基因,28例参与细胞粘附,2在细胞增殖中,和6在凝血。
    结论:HAoECs的Nic暴露导致LGALS9在转录水平上显著增加。LGALS9本身可以通过干扰各种信号传导途径而作为必需内皮细胞过程的关键调节因子,因此可以代表主动脉病变发病机理中的潜在新靶标。
    BACKGROUND: The endothelial cell layer is essential for the maintenance of various blood vessel functions. Major risk factors for endothelial dysfunction that contribute to aortic pathologies such as abdominal aortic aneurysm (AAA) and aortic dissection (AD) include smoking tobacco cigarettes and hypertension. This study explores the effects of nicotine (Nic) and angiotensin II (Ang II) on human aortic endothelial cells (HAoECs) at a transcriptional level.
    METHODS: HAoECs were exposed to 100 nM Nic and/or 100 nM Ang II. RNA sequencing (RNA-Seq) was performed to identify regulated genes following exposure. Results were validated applying RT-qPCR. GeneMANIA was used to perform in silico analysis aiming to identify potential downstream interacting genes in inflammatory, cell-adhesion, endothelial cell proliferation, and coagulation pathways.
    RESULTS: RNA-Seq identified LGALS9 (Galectin-9) as being potentially regulated following Nic exposure, while subsequent RT-qPCR experiments confirmed the transcriptional regulation (p < 0.05). Subsequent in silico analysis identified potential candidate genes for interacting with LGALS9 in different gene sets. Of the top 100 genes potentially interacting with LGALS9, 18 were inflammatory response genes, 28 were involved in cell adhesion, 2 in cell proliferation, and 6 in coagulation.
    CONCLUSIONS: Nic exposure of HAoECs causes a significant increase in LGALS9 at a transcriptional level. LGALS9 itself may serve as key regulator for essential endothelial cell processes via interfering with various signaling pathways and may thus represent a potentially novel target in the pathogenesis of aortic pathologies.

    未经证实:胸主动脉腔内修复术(TEVAR)被描述为优于开放手术方法,和以前的研究发现TEVAR的优势在于降低总体发病率和死亡率.这项研究旨在描述TEVAR对高复杂性胸主动脉疾病患者的结局。
    未经评估:描述性研究,由前瞻性收集的数据库的回顾性审查开发。纳入2012年至2022年期间接受TEVAR的18岁以上患者。患者人口统计学,围手术期数据,手术结果,发病率,并描述了死亡率。进行了统计学和多变量分析。当p值<0.05时达到统计学显著性。
    未经批准:共纳入66例患者。男性患者占60.61%,平均年龄为69.24岁。相关的主动脉疾病是动脉瘤(68.18%),溃疡相关(4.55%),壁内相关血肿(7.58%),创伤相关病理(1.52%),主动脉夹层(30.30%)。平均住院时间为18.10天,98.48%需要重症监护病房。在30天,死亡率为10.61%,再干预率为21.21%.术中失血量增加(p=0.001)和男性(p=0.04)与死亡率有统计学关系。与较高的体重指数值(p=0.04,95%置信区间[CI]=0.82-7.21)和(p=0.02,95%CI=1.31-12.57)相比,体重过轻患者的并发症和内漏风险高6.7和11.4倍。分别。
    UNASSIGNED:胸主动脉腔内修复术似乎是胸主动脉病变患者的可行选择,有足够的死亡率和发病率。体重过轻的患者似乎具有增加的总体发病率的风险和增加的内漏的风险。需要进一步的前瞻性研究来证明我们的结果。
    结论:肥胖和BMI在外科文献中被广泛研究。根据我们的研究,对于接受TEVAR治疗的患者,在与体重指数相关的术后并发症和死亡率方面存在矛盾.就该手术的术后发病率和死亡率而言,不应将其视为高风险特征。
    UNASSIGNED: Thoracic endovascular aortic repair (TEVAR) has been described to be superior to an open surgical approach, and previous studies have found superiority in TEVAR by reducing overall morbidity and mortality rates. This study aimed to describe the outcomes of TEVAR for patients with thoracic aortic disease at a high complexity.
    UNASSIGNED: Descriptive study, developed by a retrospective review of a prospectively collected database. Patients aged above 18 years who underwent TEVAR between 2012 and 2022 were included. Patient demographics, perioperative data, surgical outcomes, morbidity, and mortality were described. Statistical and multivariate analyses were made. Statistical significance was reached when p values were <0.05.
    UNASSIGNED: A total of 66 patients were included. Male patients were 60.61% and the mean age was 69.24 years. Associated aortic diseases were aneurysms (68.18%), ulcer-related (4.55%), intramural-related hematoma (7.58%), trauma-related pathology (1.52%), and aortic dissection (30.30%). The mean hospital stay was 18.10 days, and intensive care unit was required for 98.48%. At 30 days, the mortality rate was 10.61% and the reintervention rate was 21.21%. Increased intraoperative blood loss (p=0.001) and male sex (p=0.04) showed statistical relationship with mortality. Underweight patients have 6.7 and 11.4 times more risk of complications and endoleak compared with higher body mass index values (p=0.04, 95% confidence interval [CI]=0.82-7.21) and (p=0.02, 95% CI=1.31-12.57), respectively.
    UNASSIGNED: Thoracic endovascular aortic repair seems to be a feasible option for patients with thoracic aortic pathologies, with adequate rates of mortality and morbidity. Underweight patients seem to have an increased risk of overall morbidity and increased risk for endoleak. Further prospective studies are needed to prove our results.
    CONCLUSIONS: Obesity and BMI are widely studied in the surgical literature. According to our study, there is a paradox regarding the outcomes of patients treated with TEVAR in terms of postoperative complications and mortality related to the body mass index. And shouldn\'t be considered as a high-risk feature in terms of postoperative morbidity and mortality in this procedure.

    主动脉疾病是一种罕见但可能危及生命的疾病。我们提出了一系列主动脉疾病,包括胸主动脉瘤的血清蛋白质组学研究(n=11),慢性夹层(n=9),急性主动脉夹层(n=11),和手术治疗的夹层(n=19)以及健康对照(n=10)和冠心病患者(n=10)代表非主动脉心血管疾病。总的来说,我们在所有70份样本中鉴定并定量了425种蛋白质.不同的主动脉疾病代表了可区分的蛋白质组概况。我们确定了与疾病严重程度呈正相关或负相关的蛋白质簇,包括胞浆组织渗漏蛋白的增加和凝血和补体系统成分的减少。Further,我们确定了急性主动脉夹层的血清蛋白质组指纹,组成,其中,丰富的炎症标志物,如C反应蛋白和S100蛋白家族成员。该研究强调了血清蛋白质组学在主动脉疾病研究中的适用性,并强调了建立疾病特异性预后标志物的可能性。
    Aortic diseases are a rare but potentially life-threatening condition. We present a serum proteomic study for a spectrum of aortic diseases including thoracic aortic aneurysms (n = 11), chronic dissections (n = 9), acute aortic dissections (n = 11), and surgically treated dissections (n = 19) as well as healthy controls (n = 10) and patients of coronary heart disease (n = 10) to represent non-aortic cardiovascular disease. In total, we identified and quantified 425 proteins across all 70 samples. The different aortic diseases represented distinguishable proteome profiles. We identified protein clusters that positively or negatively correlate with disease severity, including increase of cytosolic tissue leakage proteins and decrease of components of the coagulation and complement system. Further, we identified a serum proteome fingerprint of acute aortic dissections, consisting, among others, of enriched inflammatory markers such as C-reactive protein and members of the S100 protein family. The study underlines the applicability of serum proteomics for the investigation of aortic diseases and highlights the possibility to establish disease-specific prognostic markers.

    共存的多级主动脉病变是由动脉粥样硬化和高血压引起的,并在一小部分患者中出现。血管内修复术是一种安全有效的治疗方法。然而,针对两个主动脉段同时使用胸血管内修复术(TEVAR)和血管内动脉瘤修复术(EVAR)的小系列和病例报告较少.确定同时和单独TEVAR和EVAR治疗多水平主动脉病变的结果。2010年至2020年间,31例患者和22例患者接受了一期和二期修复治疗,分别在一个中心。所有患者均伴有胸主动脉和腹主动脉疾病(主动脉夹层,动脉瘤,和穿透性主动脉溃疡)。与两级主动脉修复术患者相比,一期修复患者年龄较大(平均年龄,68vs.57岁;P<0.001),并且具有更大的术前最大主动脉直径(67.03±10.65vs.57.45±10.36mm;p=0.002)。术中和术后结果显示,两阶段组的手术时间和住院时间(LOS)更长。两组术后并发症无明显差别。在后续行动中,一期组的再干预自由和平均生存率为100vs.100%,92.4vs.95%,和88vs.88%在一个,两个,5年,分别,而两阶段组的平均生存率为86.4。90.5%,87vs.90.5%,和76vs.84%的人,两个,5年,分别,均无统计学差异。TEVAR和EVAR联合可以成功进行,发病率和死亡率最低。一期修复与多级主动脉病变治疗的风险增加无关。
    Coexisting multilevel aortic pathologies were caused by atherosclerosis and hypertension and presented in a small subgroup of patients. Endovascular repair is a safe and effective treatment for a variety of aortic pathologies. However, fewer small series and cases were reported using simultaneous thoracic endovascular repair (TEVAR) and endovascular aneurysm repair (EVAR) for both aortic segments. To determine the outcomes of simultaneous and separately TEVAR and EVAR treating for multilevel aortic pathologies. Between 2010 and 2020, 31 patients and 22 patients were treated by one-staged and two-staged repair, respectively at a single center. All patients had the concomitant thoracic and abdominal aortic disease (aortic dissection, aneurysms, and penetrating aortic ulcers). Compared with the patients with two-staged aortic repair, the one-staged repair patients were older (mean age, 68 vs. 57 years; P < 0.001) and had a larger preoperative maximal aortic diameter (67.03 ± 10.65 vs. 57.45 ± 10.36 mm; p = 0.002). The intraoperative and postoperative outcomes show that the procedure times and length of hospital stay (LOS) were longer in the two-staged group. There is no significant difference in postoperative complications between the two groups. In the follow up, the freedom from re-intervention and the mean survival rate for the one-staged group were 100 vs. 100%, 92.4 vs. 95%, and 88 vs. 88% at one, two, and 5 years, respectively, whereas the mean survival rate for the two-staged group was 86.4 vs. 90.5%, 87 vs. 90.5%, and 76 vs. 84% at one, two, and 5 years, respectively, all with no statistical difference. Combined TEVAR and EVAR can be performed successfully with minimal morbidity and mortality. The one-staged repair was not associated with the increased risk for multilevel aortic pathologies treatment.

    Women with known cardiovascular diseases (CVD) and a desire to have children should receive a timely comprehensive counselling before becoming pregnant. This is critical as the foundation for an informed decision-making process of the mother and her family. Furthermore, a detailed interdisciplinary management plan should be developed and discussed with the patient. The modified World Health Organization (mWHO) classification should be applied for maternal cardiovascular risk stratification. Although the prevalence of aortic pathologies is infrequent, they are often life-threatening conditions. Following the recent advances in terms of surgical management and anticoagulation, the adequate management of valvular heart disease is particularly challenging. Cardiomyopathies during pregnancy are associated with high maternal mortality and severe cardiovascular complications, such as progressive heart failure and thromboembolic events; however, novel treatment options have recently become available.
    UNASSIGNED: Frauen mit bekannten Herz-Kreislauf-Erkrankungen und Kinderwunsch sollten rechtzeitig vor der Schwangerschaft eine umfassende Beratung erhalten. Diese ist als Grundlage einer informierten Entscheidungsfindung für Mütter und deren Familien unabdingbar. Des Weiteren sollte ein Behandlungsplan interdisziplinär erstellt und mit den Patientinnen besprochen werden. Zur Risikobewertung in der Schwangerschaft sollte die modifizierte Klassifikation der Weltgesundheitsorganisation (mWHO) verwendet werden. Auch wenn es sich bei Erkrankungen der Aorta um seltene Pathologien handelt, sind diese häufig lebensbedrohlich. Herzklappenerkrankungen sind häufiger. Aufgrund neuer Möglichkeiten in der Chirurgie und der Antikoagulation stellt die Therapie von Herzklappenerkrankungen eine besondere Herausforderung dar. Kardiomyopathien in der Schwangerschaft können Todesfälle und schwere kardiovaskulärer Komplikationen, wie eine fortschreitende Herzinsuffizienz oder thromboembolische Ereignisse, verursachen. Mittlerweile sind jedoch neuartige Behandlungsmöglichkeiten verfügbar.
