BACKGROUND Multiple reports document the higher costs of primary amputation (PA) compared to infrainguinal bypass surgery (IBS). Recent reports document 40-50% cost-effectiveness for percutaneous transluminal angioplasty (PTA) compared to IBS. The literature suggests appropriate initial treatment for critical limb ischemia (CLI) to be IBS = 38%, PTA = 28%,(More)
The novel power-pulse spray (P-PS) technique maximizes and combines the advantages and minimizes the disadvantages of both chemical thrombolysis (CT) and rheolytic thrombectomy (RT). Forty-nine consecutive patients with iliofemoral thrombotic occlusion were treated via P-PS technique. Using a 6 Fr RT catheter, saline prime was exchanged for thrombolytic(More)
Critical limb ischemia (CLI) remains a poorly understood, rarely reported, and inconsistently treated major global healthcare epidemic. The incidence in the US is estimated at 1% of the population aged 50 years and older and at approximately double that rate in the over-70 age group. These frequencies are expected to increase significantly with the aging(More)
PURPOSE To report the technique of carotid endarterectomy (CEA) combined with retrograde balloon angioplasty and stenting of proximal "tandem" lesions in the supra-aortic trunk. TECHNIQUE Intraoperative techniques in 34 patients with 23 left common carotid artery (CCA) and 11 innominate artery lesions included general anesthesia, low-dose dextran,(More)
BACKGROUND The combination of glycoprotein (GP) IIb-IIIa inhibition and direct thrombin inhibition (DTI) with bivalirudin (Angiomax, The Medicines Company, Cambridge, Massachusetts) have shown ischemic and hemorrhagic outcomes benefit in coronary interventions and may have similar benefits in percutaneous peripheral interventions (PPI). The high incidence(More)
PURPOSE To evaluate the feasibility of targeted renal therapy (TRT) to decrease the rate of contrast-induced nephropathy (CIN) during endovascular aortic aneurysm repair (EVAR) in patients at risk for CIN. METHODS A prospective nonrandomized analysis of TRT was performed in 10 high-risk patients (8 men; median age 66.5 years, range 56-80) with(More)
BACKGROUND Many heparin (UFH) limitations are overcome by bivalirudin (Angiomax ). The pharmacokinetic profile of bivalirudin appears well suited for percutaneous peripheral intervention (PPI), yet few data exist regarding its safety and feasibility in this setting. METHODS One hundred and eighty renal and 75 iliac PPIs performed between May 2001 and June(More)
The popularity of mobile devices is founded on information consumption. As device capabilities increase and displays become more detailed, the demands of text rendering are also increasing. The aim of this talk is to provide a detailed overview of the problem domain of font rendering, why GPU font rendering methods are now an important consideration and(More)
The use of embolic protection devices (EPD) during lower extremity peripheral vascular interventions (PVI) remains controversial. We examine the current data and present our Louisiana experience with discussions regarding the unresolved issues surrounding the use of EPD during lower extremity PVI.
