OBJECTIVE To prospectively examine outcomes associated with an aggressive screening protocol for blunt cerebrovascular injury (BCVI), and to compare the accuracy of computed tomographic angiography (CTA) and magnetic resonance angiography (MRA) versus conventional angiography with respect to BCVI diagnosis. SUMMARY BACKGROUND DATA In the past 5 years,(More)
BACKGROUND Subintimal endovascular intervention has been used widely in the treatment of symptomatic superficial femoral artery (SFA) occlusion. The relative effectiveness of subintimal placement of a covered stent (CS) versus balloon-only subintimal angioplasty (SIA) remains uncertain. METHODS We performed a retrospective cohort study of consecutive(More)
INTRODUCTION Surgical options for vascular reconstruction in a contaminated field are limited and include prosthetic reconstruction or ligation with extra-anatomic bypass. With prosthetic insertion, rates of graft infection and failures (pseudoaneurysms and thrombosis) are high. In the emergent situations, extra-anatomic bypass is time-consuming and(More)
The following paper gives an overview of the current status of stem cell use in vascular medicine. The role of endothelial progenitor cells (EPCs) is discussed. Different approaches to use cellular based concepts are outlined: among these are the treatment of patients with critical ischemia with bone marrow derived mononuclear cells as well as our own(More)
INTRODUCTION Endovascular grafting of the aorta is gaining widespread acceptance for treating aortic aneurysms. Para-renal aneurysms or thoraco-abdominal aneurysms may be a relative contra-indication for endovascular aneurysm repair (EVAR) unless visceral vessels can be debranched. REPORT We describe a case of thoraco-abdominal aneurysm extending from the(More)
Since major meta-analyses of randomized controlled trials in interventional cardiology showed the potential of drug-eluting stents in decreasing restenosis and reintervention rates after coronary artery stenting, one of the next steps in the treatment of arterial occlusive disease is the transfer of the active coating technology towards peripheral arterial(More)
BACKGROUND The erosion of the early mortality advantage of elective endovascular aneurysm repair (EVAR) compared with open repair of abdominal aortic aneurysm remains without a satisfactory explanation. METHODS An individual-patient data meta-analysis of four multicentre randomized trials of EVAR versus open repair was conducted to a prespecified analysis(More)
OBJECTIVE We tested the hypothesis that rapamycin coated onto, and eluted from, expanded polytetrafluoroethylene (ePTFE) grafts would diminish neointimal hyperplasia in a porcine model. METHODS Rapamycin (also called sirolimus) was coated onto the luminal surface of 6-mm-internal-diameter thin-walled ePTFE grafts by using an adhesive polymer that allows(More)
BACKGROUND Clinical intestinal transplantation has been plagued by frequent and severe graft rejection. It has been proposed that the major histocompatibility complex (MHC) antigens might play a critical role in this process owing to their extensive expression on enterocytes and mucosa-associated immune cells. METHODS The present study examined the role(More)
