Newly Designed, Self-Expanding Large-Bore Nitinol Stents for Symptomatic Central Venous Stenosis: Technical and Long-Term Clinical Outcome.

Purpose: To retrospectively analyze the technical and long-term clinical outcome of angioplasty and stenting using the Venovo™ venous stent for the treatment of malignant and benign superior vena cava (SVC) occlusive disease.

Materials And Methods: Consecutive patients treated with the Venovo™ venous stent for SVC occlusive disease were included. SVC obstruction symptoms were classified according to the Kishi score.

Immediate and 90-Day Clinical Outcome of Patients with Acute Stroke Treated with the NeVa-Vesalio Mechanical Thrombectomy Device: A Retrospective Case Series.

Objective: The NeVa stent retriever is a newly designed mechanical thrombectomy device for the treatment of acute ischemic stroke caused by large vessel occlusion. We investigate the procedural characteristics and patients' clinical outcomes at discharge and at 90 days of follow-up.

Methods: We retrospectively reviewed a cohort of 75 patients (median age, 74 years) treated with the NeVa device for acute large vessel occlusion stroke.

Comparison of Clinical Performance Between Two Types of Symmetric-Tip Hemodialysis Catheters: A Single-Centre, Randomized Trial.

Purpose: To compare the clinical performance of a newly designed, symmetric-tip Arrow-Clark™ VectorFlow® tunnelled haemodialysis catheter, with a Glidepath™, symmetric-tip tunnelled haemodialysis catheter.

Material And Methods: From November 2018 to October 2020, patients with End-Stage Renal Disease requiring a de novo tunnelled catheter for hemodialysis, were randomized to Vectorflow® (n = 50) or to Glidepath™ catheter (n = 48). The primary outcome was catheter patency at one year following catheter insertion.

Embolization therapy for type 2 endoleaks after endovascular aortic aneurysm repair: imaging-based predictive factors and clinical outcomes on long-term follow-up.

Purpose: To evaluate the technical, radiological, and clinical outcomes after type 2 endoleak (T2EL) embolization in patients with a growing aneurysm sac after endovascular aortic aneurysm repair (EVAR). Additionally, to determine clinical and imaging-based factors for outcome prediction after embolization of a T2EL.

Methods: A single-institution, retrospective analysis was performed of 60 patients who underwent a T2EL embolization procedure between September 2005 and August 2016 to treat a growing aneurysm sac diameter following EVAR.

Upper gastrointestinal bleeding related to an eroded gastrosplenic collateral lately after splenic artery embolization.

Background: Upper gastrointestinal, non-variceal haemorrhage can be related to various etiologies, including peptic ulcer, neoplasm, gastritis, Dieulafoy lesions and other, rare underlying diseases. Here, we describe another, yet unreported etiology of gastric bleeding.

Case Presentation: A 49-year-old man presented with melena; gastroscopy revealed blood in the stomach without active bleeding source.

Enhanced removal of refractory humic- and fulvic-like organics from biotreated landfill leachate by ozonation in packed bubble columns.

Biotreated landfill leachate contains much refractory organics such as humic and fulvic acids, which can be degraded by O. However, the low O mass transfer and high energy cost limit its wide application in landfill leachate treatment. Previous studies proved that packed bubble columns could enhance the O mass transfer and increase the synthetic humic acids wastewater degradation, but the performance of packed bubble columns in real wastewater treatment has not been investigated.

Roof runoff contamination: Establishing material-pollutant relationships and material benchmarking based on laboratory leaching tests.

Because roofs represent a major part of the urban impervious surface, it is hypothesized that roof runoff is an important source of urban stormwater contamination. However, the contribution of different roofing materials to this contamination has only been examined to a limited extent. In this study, a resource and time efficient methodology, which uses some of the principles of a standardized leaching test (CEN/TS16637-2), was developed to identify material-pollutant relationships for sixteen commonly used roofing materials (EPDM, PVC, TPO, EVA, PU and bitumen membranes).

Factors influencing the long-term outcome of tunneled hemodialysis catheters.

Purpose: To review the incidence and type of tunneled hemodialysis catheter (THC) complications in a large cohort of patients with end-stage renal disease. Additionally, the longevity of the THC and factors predicting high risk for catheter complications were assessed.

Material And Methods: Between August 2009 and December 2016, a cohort of 538 patients underwent primary THC insertion; in 119 patients, THC was inserted after failed arteriovenous fistula or graft.
