Reporting standards for endovascular aortic repair of aneurysms involving the renal-mesenteric arteries.

J Vasc Surg 2020 Jun 29. Epub 2020 Jun 29.

MedStar Health, Washington DC.

Endovascular aortic aneurysm repair of complex aortic aneurysms requires incorporation of side branches using specially designed aortic stent-grafts with fenestrations, directional branches or parallel stent-grafts. These techniques have been increasingly utilized and reported in the literature. The purpose of this document is to clarify and update terminology, classification systems, measurement techniques and end-point definitions that are recommended for reports dealing with endovascular repair of complex abdominal and thoracoabdominal aortic aneurysms involving the renal and mesenteric arteries.

Disruption of Osteoprotegerin has complex effects on medial destruction and adventitial fibrosis during mouse abdominal aortic aneurysm formation.

PLoS One 2020 2;15(7):e0235553. Epub 2020 Jul 2.

Department of Cardiovascular Physiology and Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Japan.

Aortic aneurysm refers to dilatation of the aorta due to loss of elasticity and degenerative weakening of its wall. A preventive role for osteoprotegerin (Opg) in the development of abdominal aortic aneurysm has been reported in the CaCl2-induced aneurysm model, whereas Opg was found to promote suprarenal aortic aneurysm in the AngII-induced ApoE knockout mouse aneurysm model. To determine whether there is a common underlying mechanism to explain the impact of Opg deficiency on the vascular structure of the two aneurysm models, we analyzed suprarenal aortic tissue of 6-month-old ApoE-/-Opg-/- mice after AngII infusion for 28 days.

MiR-126-5p promotes contractile switching of aortic smooth muscle cells by targeting VEPH1 and alleviates Ang II-induced abdominal aortic aneurysm in mice.

Lab Invest 2020 Jul 1. Epub 2020 Jul 1.

Department of Vascular Surgery, The Second Affiliated Hospital of Dalian Medical University, Dalian, 116027, Liaoning, People's Republic of China.

Abdominal aortic aneurysm (AAA) is a potential lethal disease that is defined by an irreversible dilatation (>50%) of the aorta. During AAA expansion, the aortic wall is often remodeled, which is featured by extracellular matrix (ECM) degeneration, medial and adventitial inflammation, depletion and phenotypic switching of vascular smooth muscle cells (SMCs). Recent studies have suggested microRNAs as vital regulators for vascular SMC function. Read More

Long Noncoding RNA SNHG16 Facilitates Abdominal Aortic Aneurysm Progression through the miR-106b-5p/STAT3 Feedback Loop.

J Atheroscler Thromb 2020 Jul 2. Epub 2020 Jul 2.

Department of Cardiovascular Surgery, Second Affiliated Hospital of Kunming Medical University.

Aim: Deepening our understanding of the molecular mechanism of abdominal aortic aneurysm (AAA) progression will help set up novel avenues for therapeutic target identification. Our aim here was to unveil the mechanism function of STAT3 in AAA progression.

Methods: We investigated the functional role of STAT3 in AAA by evaluating vascular smooth muscle cell (VSMC) apoptosis and proliferation via terminal deoxynucleotidyl transferase dUTP nick end labeling, western blotting, 5-ethynyl-2´-deoxyuridine, and Cell Counting Kit-8 assays. Read More

Feasibility and accuracy of a novel automated three-dimensional ultrasonographic analysis system for abdominal aortic aneurysm: comparison with two-dimensional ultrasonography and computed tomography.

Cardiovasc Ultrasound 2020 Jul 1;18(1):24. Epub 2020 Jul 1.

Division of Cardiology, Severance Cardiovascular Hospital, Yonsei University College of Medicine, 50 Yonsei-ro, Seodaemun-gu, Seoul, 03722, Republic of Korea.

Background: Accurate measurement of the maximum aortic diameter (Dmax) is crucial for patients with abdominal aortic aneurysm (AAA). Aortic computed tomography (CT) provides accurate Dmax values by three-dimensional (3-D) reconstruction but may cause nephrotoxicity because of contrast use and radiation hazard. We aimed to evaluate the accuracy of a novel semi-automated 3-D ultrasonography (3-D US) system compared with that of CT as a reference. Read More

Clin Appl Thromb Hemost 2020 Jan-Dec;26:1076029620932226

School of Life and Pharmaceutical Sciences, Dalian University of Technology, Panjin, China.

This research was designed to determine the association of serum lipid peroxidation products with disease severity in patients with abdominal aortic aneurysm (AAA). In total, 76 pairs of AAA cases as well as matched controls were enrolled in our research using propensity score matching (PSM). And their malondialdehyde (MDA), lipid hydroperoxide (LPO), and glutathione peroxidase (GSH-Px) levels were also detected through enzyme-linked immunosorbent assay (ELISA). Read More

Endoluminal Management of Infra-renal Aortic and Aorto-iliac Aneurysms.

Cardiovasc Intervent Radiol 2020 Jun 21. Epub 2020 Jun 21.

Auckland Hospital, Auckland, New Zealand.

This paper reviews the development of endovascular aneurysm repair (EVAR) of infra-renal aortic and iliac artery aneurysms and considers the current status and best treatment options. The vast majority of devices are bifurcated and exclude the aneurysm utilizing the same techniques for fixation and seal. The modern EVAR procedure is usually performed in a hybrid operating theatre, utilizing image fusion and other radiation-reducing techniques and using optimized procedural techniques, including percutaneous access.

Randomised trial of telephone counselling to improve participants' adherence to prescribed drugs in a cardiovascular screening trial. A VIVA substudy.

Basic Clin Pharmacol Toxicol 2020 Jun 21. Epub 2020 Jun 21.

Department of Cardiology, Diagnostic Centre, Regional Hospital Central Jutland, Silkeborg, Denmark.

A total of 1,446 participants; 65-74-year-old men diagnosed with abdominal aortic aneurysm (AAA), peripheral arterial disease (PAD) or high blood pressure (HB) in the Viborg Vascular (VIVA) screening trial, were consecutively included and randomised to a telephone counselling (TC) or no TC 3 months after being screened positive. Data from VIVA were linked to data from Danish registers from 2007 to 2016. The primary outcome was a composite outcome of proportion of days covered (PDC) by statin, antithrombotic drugs and antihypertensive agents and for each specific drug class at 6-month follow-up.

Ann Vasc Surg 2020 Jun 17. Epub 2020 Jun 17.

Medical School, Democritus University, Alexandroupolis, Greece.

The use of social media for academic or research purposes is still in infancy. However, the potential of dissemination of medical knowledge through these electronic platforms is dynamically increasing. We performed a search on Twitter® collecting tweets containing the keywords 'peripheral arterial disease' (PAD) and 'abdominal aortic aneurysm' (AAA) separately and including three types of emitters.

LncRNA LBX2-AS1 facilitates abdominal aortic aneurysm through miR-4685-5p/LBX2 feedback loop.

Biomed Pharmacother 2020 Jun 16;129:109904. Epub 2020 Jun 16.

Department of Cardiovascular Surgery, Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology, No.1095 Jiefang Ave, Hankou, 430000 Hubei, China. Electronic address:

Long noncoding RNAs (LncRNAs) are involved in multiple processes of human malignancy, and emerge as crucial molecules in RNA biology. However, the function of lncRNAs has not been well illustrated in abdominal aortic aneurysm (AAA). In this research, the effects of dysregulated ladybird homeobox 2 antisense RNA 1 (LBX2-AS1) or ladybird homeobox 2 (LBX2) on vascular smooth muscle cell (VSMC) biological processes were surveyed via cell counting kit-8 (CCK-8), methyl thiazolyl tetrazolium (MTT), terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) and caspase-3 activity assays.

Quadriplegia and quadriparesis after endovascular aortic procedures: a catastrophic and under-reported complication?

J Cardiovasc Surg (Torino) 2020 Jun 19. Epub 2020 Jun 19.

Vascular Surgery, "Vita-Salute" University School of Medicine, San Raffaele Scientific Institute, Milan, Italy.

Purpose: to report three cases of spinal cord ischemia (SCI) involving the cervical- dorsal level and leading to quadriplegia and quadriparesis, following thoraco-abdominal aortic aneurysm (TAAA) endovascular repair.

Case Reports: A 79-year-old woman with an extent III TAAA was scheduled for a multi-step fenestrated/branched endovascular aortic repair. Immediately after the first step, consisting of standard proximal thoracic stent-graft implantation, she developed quadriplegia that did not resolve despite all therapeutic actions, and died as a consequence on postoperative day 32.
