Abstract Unusual rainfall is the primary cause of failure tailing dams, and overtopping most representative model dam failure. The upstream was selected as research object to study whole process breach extension dam-failure mechanism under full-scale condition. results showed that significant size grading phenomenon in front, middle, end pond obvious due flow separation effect, its average particle diameter D50. At different moments rainfall, height infiltration line at positions body...
To summarize a single-center experience using the single/double chimney technique in association with thoracic endovascular aortic repairs (TEVAR) for arch pathologies.From November 2007 to March 2016, 122 patients (mean age 50.4±12.7 years, range 29-80; 92 men) pathologies underwent TEVAR combined single (n=101) or double (n=21) grafts reconstruct supra-aortic branches: 21 innominate arteries, 114 left common carotid and 8 subclavian arteries (LSA). Pathologies included type B dissection...
Revascularization of the supra-aortic major branches in thoracic endovascular aortic repair (TEVAR) is challenging owing to complex anatomic configuration arch pathologies. This study aims evaluate feasibility, effectiveness, and safety three techniques-chimney, fenestrated, in-situ fenestration-for patients with pathologies.A retrospective analysis was performed involving 234 lesions, who underwent TEVAR adaptations technique (chimney, or fenestration) between January 2016 December 2017.One...
Vascular smooth muscle cells (VSMCs) undergo cell biological changes in response to a variety of cytokines and growth factors. Adiponectin inhibits neointimal formation through suppressing the proliferation migration VSMCs. However, mechanisms underlying effect adiponectin on VSMC apoptosis require further investigation. The present study was designed investigate apoptosis, focusing mitofusin‑2 (MFN2) mediated Ras‑Raf‑extracellular signal regulated kinase (Erk)1/2 signaling pathway. results...
Purpose: To evaluate the safety and feasibility of in situ needle fenestration (ISNF) technique for reconstruction left subclavian artery (LSA) during thoracic endovascular aortic repair (TEVAR) complicated arch pathologies. Materials Methods: A retrospective review was conducted from January 2014 to December 2019 50 patients (mean age 60.2±11.1; 45 men) who underwent ISNF revascularize LSA TEVAR. Twenty-one also required revascularization common carotid (LCCA; n=19) innominate (IA; n=2)...
To investigate the interaction between blasting crack and circular hole with various offset distances in PMMA, this study examined propagation arrest mechanisms of utilizing a dynamic caustics experimental system. When distance (d) ≥ 8 mm, had negligible effect on propagation. d = 6 velocity mode I stress intensity factor propagating near were significantly reduced. The exerted notable hindering crack, however, it did not completely initially approaches subsequently moves away from hole. ≤ 4...
To report our early experience with endovascular repair of acute non-A-non-B aortic dissections using chimney grafts to preserve blood flow a left common carotid artery (LCCA) located in the proximal landing zone.From June 2009 May 2010, 8 patients (7 men; mean age 49 years, range 29-75) dissection and no adequate sealing zones underwent thoracic (TEVAR). Covered stents were placed parallel stent-grafts restore LCCAs while extending fixation zones; subclavian arteries intentionally covered...
Objective This study was performed to describe the treatment of aortic arch pathologies with a physician-modified fenestration (PMF) technique in thoracic endovascular repair (TEVAR). Methods From August 2015 2017, 32 patients underwent TEVAR PMF technique. All patients’ clinical data were analyzed GraphPad Prism 7.0. Results Thirty-four stent-grafts implanted patients. The mean proximal diameter stent-graft 32.4 ± 3.4 cm, and length 170.0 25.2 cm. Twenty-nine procedures preserve left...
Objective This study aimed to summarize the long-term experience of using chimney technique in thoracic endovascular aortic repair (TEVAR) for arch diseases. Methods From November 2007 June 2021, a total 345 consecutive patients (mean age 56 ± 11.3 years, range 28–83, 302 men) with pathologies underwent TEVAR combined (cTEVAR). Their medical data and follow-up results were retrospectively reviewed analyzed. Results Among patients, 278 (80.6%) received single chimneys, 53 (15.4%) double 7...
This paper presents a study on the numerical performance of three contact simulation methods, namely, interface element, thin-layer and analysis through behavior between concrete face slab dam body high concrete-faced rockfill named Tianshengqiao-I in China. To investigate accuracy limitations each method, results are compared terms deformation, stress along interface, stresses slab, separation from cushion layer. In particular, predicted deformation with in-situ observation data to classify...
The tensile fracture characteristics of compacted soils are very important for the stability earth structures. In this work, a horizontal displacement-controlled, uniaxial, direct-tension test apparatus was developed to capture complete stress-deformation response cohesive soils. A series uniaxial tests were performed on two soils, and cracking process observed. curves showed clear postpeak softening behavior along with development cracks. influences water content dry density strength...
ObjectiveThe aim of this study was to evaluate safety and efficacy thoracic endovascular aortic repair (TEVAR) for acute Stanford type B dissection (TBAD) with retrograde A intramural hematoma (TAIMH).MethodsPatients TBAD TAIMH treated TEVAR between January 1, 2014, March 31, 2022, were retrospectively reviewed. Aortic diameter distance measured using the 3D Slicer image computing platform. Patients' characteristics, procedural, in-hospital follow-up data, remodeling...
PurposeTo report the outcome of intended celiac artery coverage during thoracic endovascular aortic repair (TEVAR) for type B dissection with an intimal tear near (CA) orifice. MethodsBetween 2007 and 2011, 13 patients (10 men; mean age 61.3 years, range 46–70) underwent primary (n=9) or secondary (n=4) TEVAR intentional CA coverage. Preoperative imaging was performed to confirm existence collateral circulation between superior mesenteric artery. A short stent-graft then deployed cover both...
