PURPOSE To report the 6-month angiographic results from a prospective single-center study investigating the efficacy and outcome of sirolimus-eluting stents used for bailout after infrapopliteal revascularization of patients with critical limb ischemia (CLI). METHODS Twenty-nine patients (21 men; mean age 68.7 years) underwent infrapopliteal(More)
The use of small animal models in basic and preclinical sciences constitutes an integral part of testing new pharmaceutical agents prior to commercial translation to clinical practice. Whole-body small animal imaging is a particularly elegant and cost-effective experimental platform for the timely validation and commercialization of novel agents from the(More)
PURPOSE To report the 1-year angiographic and clinical outcome from a prospective single-center study investigating the infrapopliteal application of sirolimus-eluting versus bare metal stents in patients with critical limb ischemia (CLI) who underwent below-the-knee endovascular revascularization. METHODS Stenting was performed as a bailout procedure for(More)
PURPOSE Optical coherence tomography (OCT) is a catheter-based imaging method that employs near-infrared light to produce high-resolution cross-sectional intravascular images. The authors propose a segmentation technique for automatic lumen area extraction and stent strut detection in intravascular OCT images for the purpose of quantitative analysis of(More)
Therapeutic angiogenesis is based on the premise that the development of new blood vessels can be augmented by exogenous administration of the appropriate growth factors. Over the last years, successful preclinical studies and promising results of early clinical trials have created great excitement about the potential of therapeutic angiogenesis for(More)
PURPOSE To report the midterm (<or=1 year) angiographic and clinical outcomes of a prospective study investigating the infrapopliteal application of paclitaxel-eluting stents (PES) in patients with critical limb ischemia (CLI). MATERIALS AND METHODS Infrapopliteal angioplasty was chosen as first-line therapy in patients with unilateral or bilateral CLI(More)
BACKGROUND Compared with angiogenesis, arteriogenesis is a distinct process based on the remodeling and maturation of pre-existing arterioles into large conductance arteries. Therapeutic angiogenesis has been proposed as a potential treatment for ischemic atherosclerotic diseases. Since a variety of angiogenic factors have been tested with inconsistent so(More)
The present study reports on computational fluid dynamics in the case of severe renal artery stenosis (RAS). An anatomically realistic model of a renal artery was reconstructed from CT scans, and used to conduct CFD simulations of blood flow across RAS. The recently developed shear stress transport (SST) turbulence model was pivotally applied in the(More)
PURPOSE Ureteral patency in malignant ureteral obstruction cases is a therapeutic challenge. We report our long-term experience with palliative treatment for extrinsic malignant ureteral obstruction with percutaneous placement of metal mesh stents. MATERIALS AND METHODS From January 1996 to December 2005, 90 patients with a mean age of 59 years (range 35(More)
PURPOSE To investigate distal embolism during endovascular procedures of the infra-aortic arteries by utilizing a commercial filter basket and unveil any correlation between the baseline clinical and procedural variables and the histopathological findings of the collected particles. METHODS In a prospective study, 48 patients (37 men; mean age 70.8+/-7.8(More)
