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...

BACKGROUND: The aim of this paper was to evaluate the efficacy of percutaneous transluminal angioplasty and the intra-arterial infusion of thrombolytic drugs in the treatment of lower extremity (LE) arterial occlusion during thromboangiitis obliterans (TO). METHODS: Between February 2008 and October 2013, 13 consecutive patients with TO and LE arterial occlusion underwent 18 sessions of PTA. One LE was affected in 11 patients and both LEs in two patients. An antegrade approach with transfemoral access was used in 17 procedures, and a retrograde approach via the contralateral common femoral artery (CFA) in one procedure...

PURPOSE: Superior vena cava (SVC) syndrome owing to benign etiology is rare and endovascular techniques have been advocated as the treatment of choice. We report a case of endovascular revascularization of a port catheter-associated complete occlusion of the SVC with reversed flow in the azygos vein. METHODS: In this setting using a sheath in combination with its dilatator to pass the occlusion of the SVC after neither a diagnostic catheter nor a PTA balloon would pass the lesion may be a valid option...

Dopaminergic signaling has long been known to be a critical factor in nicotine addiction, as well as other drugs of abuse. Dopaminergic projections from the VTA to the nucleus accumbens and prefrontal cortex have been well established to be critical to the reinforcing effects of these drugs. However, other projections of dopamine neurons are likely to have significant roles in this process. Also, the relative contributions of D1 and D2 dopamine receptors in drug addiction and its treatment remain to be fully understood...
