Lipoprotein (a) (Lp(a)) is a well-documented risk factor for atherosclerotic cardiovascular disease. Its role in acute thrombo-embolic occlusions of peripheral arteries is not known. We describe two cases of multiple, acute, peripheral arterial occlusions in two previously healthy men with markedly elevated Lp(a). Both cases had unsatisfactory results after percutaneous ...

BACKGROUND: Peripheral arterial disease (PAD) is a common disease that is diagnosed with a screening test called the Ankle Brachial Index (ABI). Different methods of ABI have been described in the literature. We wanted to estimate and compare the sensitivity and specificity of an alternative method of calculating the ABI ...

Peripheral vascular disease is an obstacle to the use of continuous aortic flow augmentation (CAFA). The authors used CAFA in a patient with a 50% stenosis of the left iliac artery. Five hours after initiating therapy, flow rates dropped from 1.47 L/min to 0.2 L/min, possibly due to obstruction around ...

Acute leukemia may be associated with coagulopathy, predominantly severe bleeding diathesis caused by disseminated intravascular coagulation (DIC) and/or hyperfibrinolysis. Disordered hemostasis is characteristic for acute promyelocytic leukemia (APL, FAB M3). However, thromboembolic events such as arterial occlusion localized to the large vessels at presentation is very rare and almost exclusively ...

Chronic kidney disease is accompanied by increased large-artery stiffness, but the relation between glomerular filtration rate within the reference range and central or peripheral arterial stiffness has been understudied. The link between renal function and arterial stiffness was assessed in 305 patients with never-treated essential hypertension (men: 58%; age: 48+/-11 ...

Ankle-brachial pressure index (ABI) is a simple, inexpensive, and useful tool in the detection of peripheral arterial occlusive disease (PAD). The current guidelines published by the American Heart Association define ABI as the quotient of the higher of the systolic blood pressures (SBPs) of the two ankle arteries of that ...

Intravascular ultrasound (IVUS) has emerged as a useful and often necessary adjunct in a rising number of catheter-based peripheral interventions. IVUS catheters enable luminal and transmural cross-sectional imaging of peripheral vessels with high dimensional accuracy and provide detailed information about lesion morphology. IVUS is able to guide the optimal choice ...

Neurofibromatosis type 1, also called von Recklinghausen's disease, is an autosomal dominant disorder linked to chromosome 17, characterized by growth impairment of the neural crest cells (ectoderm) manifested by multiple neural tumors, cutaneous pigmentations, and Lisch nodules. Disease phenotype develops with time, making its penetrance almost complete by 5 years ...

Following arterial occlusion, blood vessels respond by sprouting new capillaries (i.e. angiogenesis) and by growing and remodelling pre-existing arterioles into physiologically relevant arteries (i.e. arteriogenesis). The importance of nitric oxide (NO) in ischemia-induced angiogenesis is supported by 4 main findings: (i) the ischemic limb shows an increase in endothelial nitric ...

BACKGROUND: Peripheral artery disease is a common condition, mainly associated with clinical cardiovascular risk factors. Patients with peripheral artery disease suffer from coronary artery disease-related complications. On the other hand, metabolic syndrome, as a constellation of specific risk factors, represents a risk factor for cardiovascular mortality. Metabolic syndrome might increase ...

Background: Arteriography has been considered the "Gold Standard" for the investigation of Peripheral arterial occlusive disease (PAOD). The development of Colour flow Doppler (CFD) has extended the scope of non-invasive assessment of chronic lower limb arterial disease. Aims: To evaluate and correlate the findings of CFD with arteriography as the ...

Excimer laser atherectomy (LA) employs precision laser energy control (shallow tissue penetration) and safer wavelengths (ultraviolet as opposed to the infrared spectra in older laser technology), which decreases perforation and thermal injury to the treated vessels. Though extensively used by cardiologists for severe obstructive coronary artery disease, peripheral interventionalists have ...

Recent data have shown a higher incidence of arterial events in patients with venous thromboembolism (VTE) of unknown origin than in those with the secondary form of disease. Whether patients with idiopathic VTE have a higher risk of subsequent arterial events than the general population is unknown. The aim was ...

We hypothesized that measures of arterial stiffness and wave reflection influence functional capacity of patients with peripheral arterial disease (PAD). Consecutive patients (n=106, 69+/-10 years, 66% men) referred for lower extremity arterial evaluation were studied. Radial artery pulse waveforms were obtained by applanation tonometry and an ascending aortic pressure waveform ...

Transcatheter embolotherapy (TCE), a common procedure for interventional radiologists, comprises transcatheter delivery of embolic agents into target vessels in order to eliminate lesions or lesion-associated symptoms. Good knowledge of delivery catheters and embolic agents is essential to optimize embolization techniques and to obtain the desired therapeutic outcomes. In this review, ...

Doppler evaluation in erectile dysfunction (ED) has a significant role in determining the cause of ED. The advantages of penile Doppler and pharmacologic duplex ultrasonography include objective, minimally invasive evaluation of penile hemodynamics at a relatively low cost. Arteriogenic ED may be secondary to peripheral vascular disease and diabetes, or ...
Miller, Thomas A.
The 133xenon clearance test is an easy, noninvasive method to assess arterial blood flow and can distinguish a normal from an ischemic limb. In addition, the close correlation with clinical findings affords an objective method of evaluating the results of surgical revascularization. On the basis of these findings, we feel ...

There are several strategies for cell delivery in cardiac stem cell therapy. The cells can be delivered through coronary arteries, coronary veins, or peripheral veins. Alternatively, direct intramyocardial injection can be performed, using a surgical, transendocardial, or transvenous approach. In this article, we describe the most important conceptual aspects and ...

Patients submitted to orthotopic liver transplantation (OLT) show an increased rate of cardiovascular events. OLT subjects have high homocysteine (Hcy) levels, but no data are available on the association of Hcy with cardiovascular events. In a cross-sectional analysis, 230 subjects were studied at least 6 months after OLT (159 on ...

Peripheral arterial disease in the legs represents a subset of atherosclerosis that manifests a particularly sinister profile. A predominance of sympathetic activity in the periphery favors the development of neurogenic atherosclerosis. Atherosclerosis may then produce flow derangements and decreased physical activity that serves to escalate sympathetic bias in a vicious ...

In patients at risk for coronary atherosclerosis, brachial artery flow-mediated dilation (FMD) rules out significant coronary artery disease (CAD). However, the value of this approach is unknown in patients with peripheral arterial disease who are at increased risk for CAD. This study assessed whether the noninvasive evaluation of endothelial function ...
