BACKGROUND: Although cigarette smoking is thought to constrict peripheral vessels, details have not been clarified because of the limitation of spatial resolution in conventional X-ray angiography systems. Synchrotron radiation microangiography can identify small arteries down to 50 microm in diameter. METHOD AND RESULTS: Male Wistar rats (n=9) were made to ...

Duplex arteriography may be a potential replacement of preoperative standard contrast arteriography for peripheral arterial imaging in lower extremity revascularization procedures. In patients with chronic or acute ischemia, a well-performed duplex arteriography offers several practical advantages over contrast arteriography: it is noninvasive; it does not require nephrotoxic agents; it is ...

PURPOSE: To describe our preliminary experience with a new liquid embolization agent, Onyx, in peripheral interventions. METHODS AND RESULTS: We successfully treated two peripheral aneurysms (one in an internal iliac artery, one in a thoracic collateral artery of an aortic coarctation), two peripheral pseudoaneurysms (one in a lumbar artery, one ...

Endovascular therapy is a rapidly evolving field for the treatment of patients with peripheral arterial disease, and a magnitude of studies reporting on various modern revascularization concepts have been recently published. Thus, studies assessing the efficacy of endovascular therapy of peripheral arteries do not operate with uniformly defined endpoints, rendering ...

Pulmonary artery aneurysm (PAA), especially the peripheral type, is a rare disease. We report 2 cases of peripheral PAA with pulmonary artery hypertension. Complication associated with peripheral PAA was hemoptysis. Endovascular coil embolization was performed successfully in one patient. The other with peripheral PAA was died of massive hemoptysis. In ...

BACKGROUND: Naturally-occurring regulatory T cells (Treg) constitute a mature T-cell population characterized phenotypically by co-expression of CD4 and CD25(high) surface molecules. We investigated here the frequency of circulating Treg in patients presenting with STEMI in comparison with subjects without coronary artery disease (CAD). The effect of primary percutaneous coronary intervention ...

Atherosclerotic peripheral arterial disease is a common medical problem worldwide and portends a poor prognosis because of increased cardiovascular morbidity and mortality. Regular exercise, weight loss, and aggressive risk factor modification, including treatment of dyslipidemia and complete cessation of smoking, is extremely important in this high-risk cohort. Vascular surgery in ...

Stenosis degree is the most common criterion used to assess the severity of atherosclerosis. This form of peripheral arterial disease (PAD) is often present in lower limb arteries. However, to detect and quantify distributed arterial stenoses in lower limbs, a high precision is required over a long segment. Moreover, to ...

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 ...

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 ...

The interventional treatment of peripheral atherosclerotic occlusive disease is increasingly becoming accepted as an appropriate initial form of therapy. Standard methods of treatment include balloon angioplasty and stent assisted angioplasty. Laser catheters and mechanical atherectomy catheters are newer tools, which can be utilized to assist in achieving and maintaining patency ...

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 ...
