OBJECTIVE: Oxidative stress is involved in the pathogenesis of atherosclerosis. 8-Hydroxy-2'-deoxyguanosine (8-OHdG), an oxidative product of DNA, is a sensitive biomarker to reflect oxidative stress status in vivo. However, the circulating 8-OHdG levels in patients with coronary artery disease (CAD) have not yet been elucidated. The purpose of this study ...

BACKGROUND: Small deep brain infarcts are often caused by two different vascular pathologies: 1. atheromatous occlusion at the orifice of large caliber penetrating arteries termed branch atheromatous disease (BAD) and 2. lipohyalinotic degenerative changes termed lipohyalinotic degeneration (LD). We herein analyze and describe the characteristics of these 2 different pathologies. ...

Intracavernous carotid artery aneurysms (ICCAs) are rarely associated with life-threatening complications. We describe a 55-year-old woman who, after the rupture of an intracavernous carotid artery aneurysm, presented with a contralateral cavernous sinus syndrome and severe posterior fossa and spinal cord symptoms. Following parent artery occlusion, thrombosis of the posterior fossa ...

Arterial responses to diverse pathologies and insults likely occur via similar mechanisms. For example, many studies suggest that the natural process of aging and isolated systolic hypertension share many characteristics in arteries, including loss of functional elastin, decreased smooth muscle tone, and altered rates of deposition, and/or crosslinking of fibrillar ...

Polymeric endoaortic paving (PEAP) may improve endovascular repair of abdominal aortic aneurysms (AAA) since it has the potential to treat patients with complex AAA geometries while reducing the incidence of migration and endoleak. Polycaprolactone (PCL)/polyurethane (PU) blends are proposed as PEAP materials due to their range of mechanical properties, thermoformability, ...

High-risk plaques that are vulnerable to rupture demonstrate distinct morphological characteristics. They are differentiated from the lesions responsible for stable coronary artery disease by their large necrotic cores, thin-inflamed fibrous caps, and positive remodeling. Adiponectin is an adipocytokine that is reduced in obesity and type 2 diabetes. Hypoadiponectinemia has been ...

In cardiosurgery patients atherosclerotic debris displaced from the cannulation site but also from the opposite aortic wall by the "sandblast-like" effect of the high-pressure jet emanating from the cannula is a potential source of intraoperative arterial embolization and consequently postoperative neurologic dysfunction. The present study examined the extent to which ...

Introduction.  Aging and hypertension increase the risk of erectile dysfunction (ED) and cardiovascular disease. Arterial insufficiency is likely a primary factor in hypertension-related ED. Given the dominance of internal pudendal arteries in controlling penile vascular resistance, pathological changes in this vessel would be critical for inducing ED in aged hypertensives. ...

Type A and type B aortic dissections typically result from intimal tears above the sinotubular junction and distal to the left subclavian artery (LSA) ostium, respectively. We hypothesized that this pathology results from elevated pressure-induced regional wall stress. We identified 47 individuals with normal thoracic aortas by electrocardiogram-gated computed tomography ...

The purpose of this study was to evaluate endothelial function after post-dilation of bare-metal stents with paclitaxel-coated balloons (PCB) or non-drug-coated balloons (non-DCB) in a porcine model. DCB are an attractive alternative to drug-eluting stents because they provide short duration of drug exposure, while potentially inhibiting in-stent restenosis. Drug-eluting stents ...

Intravascular stents were first introduced in the 1980s as an adjunct to primary angioplasty for management of early complications, including arterial dissection, or treatment of an inadequate technical outcome due to early elastic recoil of the atherosclerotic lesion. Despite the beneficial effects of stenting, persistent high rates of restenosis motivated ...
