Coarctation of aorta is a rare congenital malformation and is usually accompanied by other cardiac or vascular lesions. In this case we describe a 51-year-old patient presented with coarctation of the aortic arch and postcoarctation ectasia concomitant with a left subclavian artery aneurysm. Endovascular therapy included the deployment of an inverted wedge-shaped covered stent inserted by a long "chimney" stent and another cylinder-covered stent, forming a "sandwich"-like configuration. The symptoms were alleviated after surgery, and no perioperative or stent-graft-related complications were observed at a 2-year follow-up...

PURPOSE: To systematically review and meta-analyze the added value of 3-dimensional (3D) image fusion technology in endovascular aortic repair for its potential to reduce contrast media volume, radiation dose, procedure time, and fluoroscopy time. METHODS: Electronic databases were systematically searched for studies published between January 2010 and March 2016 that included a control group describing 3D fusion imaging in endovascular aortic procedures. Two independent reviewers assessed the methodological quality of the included studies and extracted data on iodinated contrast volume, radiation dose, procedure time, and fluoroscopy time...

The dynamics of a large stock of organic matter contained in deep sediments of marginal seas plays pivotal role in global carbon cycle, yet it is poorly constrained. Here, dissolved organic matter (DOM) in sediments was investigated for core sediment up to ~240 meters deep in the East/Japan Sea. The upper downcore profile (≤118 mbsf, or meters below seafloor) at a non-chimney site (U1) featured the exponential production of dissolved organic carbon (DOC) and optically active DOM with time in the pore water above sulfate-methane-transition-zone (SMTZ), concurrent with the increases of nutrients and alkalinity, and the reduction of sulfate...

To report a case of pararenal aortic aneurysm (PAAA) with narrowed iliac arteries treated by the chimney technique combined with the INCRAFT(®) AAA stent graft system. A 75-year-old man was diagnosed with a 55mm PAAA. Patient was judged unfit for open repair and for standard endovascular repair (EVAR) due to its clinical and anatomical requirements. Custom-made fenestrated device (FEVAR) was excluded due to the presence of narrowed and heavily calcified iliac axes. Consequently, patient underwent auspicious endovascular aneurysm repair with the INCRAFT(®) System and chimney grafts in the superior mesenteric artery and both renal arteries...

BACKGROUND: Aim of this study was to evaluate our preliminary experience with the use of the Endurant II short form (IIs) stent-graft in the treatment of abdominal aortic aneurysms (AAAs). METHODS: Between November 2014 and November 2015, 79 patients were consecutively treated with the Endurant IIs stent-graft at 3 European vascular centers. Early (30-day) results in terms of technical success, limb occlusion, major morbidity, and mortality were analyzed. Estimated 1-year outcomes in terms of survival, freedom from type I endoleak, freedom from limb occlusion, and freedom from any device-related reinterventions were assessed with Kaplan- Meyer method...

Concerns about global warming phenomena induced the development of research about the control of anthropogenic greenhouse gases emissions. The current work studies on the scaling up of aqueous mineral carbonation route to reduce the CO2 emissions at the chimney of industrial emitters. The reactivity of serpentinite in a stirred tank reactor was studied for several partial pressures of CO2 (pCO2) (0.4, 0.7, 1.3 and 1.6 bar). Prior to carbonation, the feedstock was finely grinded and dehydroxyled at 650 °C by a thermal treatment...

The method of hybrid arch thoracic endovascular aortic repair (TEVAR) to treat aneurysm with zone 0 landing has changed according to its invasiveness and complications. The real chimney technique allows supra-aortic bypass from ascending aorta without side clamp is the current choice of treatment. The comprehensive strategy to prevent stroke during hybrid arch TEVAR consisting of magnetization-prepared rapid acquisition with gradient-echo for evaluation of the atheromatous change and balloon protection of the left subclavian artery has contributed for the marked reduction of stroke...

INTRODUCTION: Aneurysm regression and target vessel patency during early and mid-term follow-up may be related to the effect of stent graft configuration on the anatomy. We quantified geometry and remodeling of the renal arteries and aneurysm following fenestrated (F-) or snorkel/chimney (Sn-) endovascular aneurysm repair (EVAR). METHODS: 29 patients (mean age, 76.8±7.8 years) treated with F- or Sn-EVAR underwent computed tomography angiography at pre-op, post-op, and follow-up...

A 77-year-old male patient presented with a symptomatic, 66-mm pararenal aortic aneurysm. The patient was classified as unsuitable for open surgery due to significant comorbidities. Fenestrated or branched endografts were contraindicated due to the poor iliac access (6 mm diameter). A double Nellix with chimney endovascular aneurysm sealing (ChEVAS) technique was selected to exclude the pararenal aortic aneurysm and to preserve renal arteries and the superior mesenteric artery. Technical preplanning considered the ideal proximal landing zone to be close to the origin of the almost occluded celiac trunk and the distal common iliac arteries as the ideal distal landing zone...

At deep-sea hydrothermal vents, primary production is carried out by chemolithoautotrophic microorganisms, with the oxidation of reduced sulfur compounds being a major driver for microbial carbon fixation. Dense and highly diverse assemblies of sulfur-oxidizing bacteria (SOB) are observed, yet the principles of niche differentiation between the different SOB across geochemical gradients remain poorly understood. In this study niche differentiation of the key SOB was addressed by extensive sampling of active sulfidic vents at six different hydrothermal venting sites in the Manus Basin, off Papua New Guinea...

PURPOSE: CO₂ leakage along the trocar (chimney effect) has been proposed to be an important factor underlying port-site metastasis after laparoscopic surgery. This study aimed to test this hypothesis by comparing the incidence of port-site metastasis between B-ultrasound-guided and laparoscopically-assisted hyperthermic intraperitoneal perfusion chemotherapy (HIPPC). MATERIALS AND METHODS: Sixty-two patients with malignant ascites induced by gastrointestinal or ovarian cancer were divided into two groups to receive either B-ultrasound-guided or laparoscopically-assisted HIPPC...
