Background/Aims: The strategy of access care at out center involves the use of ultrasound (USG) in case of physical examination (PE) abnormality. USG determines the need of angiography. This study investigated the possible association between the need for percutaneous transluminal angioplasty (PTA) and hemodynamic parameters of USG. The study also assessed the effects of this monitoring strategy on outcomes in comparison with a historical control. Methods: A retrospective study of the medical records of 127 patients (65 PTA, 62 non-PTA) was conducted...

Venous thrombosis of pancreas transplant allografts often leads to graft loss. Its worrisome complication and difficult to treat, forming the most common nonimmunological cause of graft loss. Multiple risk factors have been implicated in the development of venous thrombosis of pancreas transplant. Color Doppler ultrasonography (CDUS) enables early diagnosis of venous thrombosis, thus increasing the possibility of graft-rescue treatments. Endovascular management of pancreatic transplant vascular complications are scant and in the form of case reports...

Monocytes are mononuclear cells characterized by distinct morphology and expression of CD14 and CD16 surface receptors. Classical, quiescent monocytes are positive for CD14 (lipopolysaccharide receptor) but do not express Fc gamma receptor III (CD16). Intermediate monocytes coexpress CD16 and CD14. Nonclassical monocytes with low expression of CD14 represent mature macrophage-like monocytes. Monocyte behavior in peripheral arterial disease (PAD) and during vessel wall directed treatment is not well defined...

Matthias Barton, Johannes Grüntzig, Marc Husmann, Josef Rösch
In 1974, at the Medical Policlinic of the University of Zürich, German-born physician-scientist Andreas Grüntzig (1939-1985) for the first time applied a balloon-tipped catheter to re-open a severely stenosed femoral artery, a procedure, which he initially called "percutaneous transluminal dilatation". Balloon angioplasty as a therapy of atherosclerotic vascular disease, for which Grüntzig and Charles T. Dotter (1920-1985) received a nomination for the Nobel Prize in Physiology or Medicine in 1978, became one of the most successful examples of translational medicine in the twentieth century...

PURPOSE: Neointimal hyperplasia (NH) causes vascular access (VA) stenosis, which results in serious under-dialytic morbidity in hemodialysis patients. We sought to assess whether a vitamin D intervention to NH lesions leads to better VA patency and examined clinical and in vitro studies. METHODS: A pilot clinical study of six hemodialysis patients was conducted to elucidate whether 0.5 μg calcitriol injection to stenotic lesion after balloon angioplasty (PTA) maintains better vessel patency until the next follow-up angiography...
