Surveillance of Arteriovenous Accesses with the use of Duplex Doppler Ultrasonography
Stenosis is the most frequent vascular access complication and is responsible for access thrombosis and thus long-term patency limitation. Regular arteriovenous graft (AVG) examination byExpand
Diversity, ecology and community structure of the freshwater littoral diatom flora from Petuniabukta (Spitsbergen)
Despite the frequent application of diatoms in palaeoecological research in the High Arctic, our knowledge concerning the diversity, ecology, community associations, community dynamics and survivalExpand
Heterolobosean amoebae from Arctic and Antarctic extremes: 18 novel strains of Allovahlkampfia, Vahlkampfia and Naegleria.
The diversity of heterolobosean amoebae, important members of soil, marine and freshwater microeukaryote communities in the temperate zones, is greatly under-explored in high latitudes. To addressExpand
Hemodynamic changes in patients with extracorporeal membrane oxygenation (ECMO) demonstrated by contrast-enhanced CT examinations - implications for image acquisition technique
Extracorporeal membrane oxygenation (ECMO) is an established tool for respiratory and circulatory support. In computed tomography, altered hemodynamics in ECMO patients requires specialExpand
Seasonal hydrological and suspended sediment transport dynamics in proglacial streams, James Ross Island, Antarctica
ABSTRACT Rapid warming of the Antarctic Peninsula is producing accelerated glacier mass loss and can be expected to have significant impacts on meltwater runoff regimes and proglacial fluvialExpand
More Precise Diagnosis of Access Stenosis: Ultrasonography versus Angiography
Purpose Patency of mature vascular access for hemodialysis is mostly limited by the growing stenoses leading to acute access thrombosis. The therapy of choice is usually percutaneous balloonExpand
Technique and follow-up of minimally invasive Heller myotomy for achalasia
BackgroundLaparoscopic Heller myotomy has been proven effective. Reliable predictive factors for outcome and the true benefit of the da Vinci robotic system, however, remain unknown.MethodsSeventyExpand
Treatment of failing arterio-venous dialysis graft by angioplasty, stent, and stent graft: Two-years analysis of patency rates and cost-effectiveness.
The objective of this prospective randomized single-center study was to compare primary and secondary patency rates, number of percutaneous transluminal angioplasty (PTA) interventions andExpand
Identifying Aftercare Supports for Out-of-Home Transitions: A Descriptive Analysis of Youth Perceptions and Preparedness.
Youth served in residential care often demonstrate significant educational and behavioral gains during treatment; however, struggles evidenced during the reunification and reintegration processExpand
Arteriovenous Grafts: Early Ultrasonography Tells Their Fortune
Background: The patency of arteriovenous grafts (AVG) for hemodialysis is mostly limited by growing stenoses that lead to decreasing of blood flow, thromboses and finally to access failure. The aimExpand
