The Radial Artery Patency and Clinical Outcomes Study (RAPCO) was devised and implemented in Melbourne in order to establish the appropriate place of the radial artery in the hierarchy of conduits available to the modern coronary bypass surgeon. Designed as a biological comparison with minimisation of other confounding variables, it ...

Shear stress can enhance differentiation of human embryonic stem cells (hESC) to vascular cells. We tested the hypothesis that intra-arterial hESC injection will lead to arteriogenesis while intramuscular injection will have no effect on vascularization. The superficial femoral arteries were excised on both hind limbs in athymic rats. hESC (2×10(6)) ...

An anterior tibial artery pseudoaneurysm is a rare and unexpected complication of Steinmann pin insertion. We describe the case of an 18-year-old boy, who sustained such an injury to the anterior tibial artery during this procedure. Diagnosis was confirmed on a magnetic resonance (MR) angiogram. Aneurysmal sac excision with lateral ...

Summary: A 60-year-old man with direct carotid cavernous fistula (CCF) due to a motor vehicle accident underwent internal carotid artery trapping following high-flow external carotid to internal carotid artery bypass (EC-IC bypass). Follow-up angiography revealed ipsilateral complex indirect cavernous arteriovenous fistula. Although the traumatic indirect CCF angioarchitecture differs from cavernous-sinus ...

A 42-year-old-woman presented with de novo crescendo angina. Thallium-scintigraphy showed inferior ischemia. Coronary angiogram revealed a right coronary artery (RCA), originating from the left sinus of Valsalva with a severe proximal systolic compression. She underwent successful transradial percutaneous coronary intervention with stent implantation. Multislice-computed tomography (MSCT) is usually used to ...

Previous studies have established effects of exercise training on arterial wall thickness, remodeling, and function in humans, but the extent to which these changes are locally or systemically mediated is unclear. We examined the brachial arteries of the dominant (D) and nondominant (ND) upper limbs of elite racquet sportsmen and ...

Vein graft-to-vein graft anastomosis, creating a 'Y' graft, is a useful technique when there is a lack of good-quality autologous vein to perform individual aorto-coronary bypass grafts or when the ascending aorta is short or atheromatous, limiting the space for proximal graft anastomosis. Unlike artery-to-artery composite grafts, which are resistant ...

Congenitally diseased valves are relatively frequent causes of significant morbidity and mortality. Pathology descriptions of such valves have primarily focused on gross structural features including the number of leaflets or commissures (bicuspid/bicommissural valve) and alterations in the contour, thickness, and consistency of the leaflets (dysplastic valve). Functional correlates of these ...

Adrenal artery aneurysms are an extremely rare clinical entity. Only six previous case reports of adrenal artery aneurysms exist, all of which were discovered after rupture. Herein, we describe the discovery of an unruptured adrenal artery aneurysm found during laparoscopic adrenalectomy for pheochromocytoma.

INTRODUCTION: Rarely in the anterior circulation, an anastomosis of the carotid and anterior cerebral arteries occurs when an anomalous branch arises from the ophthalmic segment of the internal carotid artery and anastomoses with the A1-A2 junction of the anterior communicating artery. Right-side predominance is known. To our knowledge, the incidence ...

A potential advantage of the right ventricle to pulmonary artery versus modified Blalock-Taussig shunt in patients undergoing the Norwood procedure is limitation of diastolic runoff from the systemic to pulmonary circulation. We evaluated mesenteric flow patterns and gastrointestinal outcomes following the Norwood procedure associated with either shunt type. Patients randomized ...

Pulmonary arteriovenous malformations caused by abnormal hepatic flow distribution can develop in patients with a single ventricle with an interrupted inferior vena cava. However, preoperatively determining the hepatic baffle design that optimizes hepatic flow distribution is far from trivial. The current study combines virtual surgery and numeric simulations to identify ...

Renal failure is associated with aortic valve calcification. Using our rat model of uremia-induced reversible aortic valve calcification, we assessed the role of apoptosis and survival pathways in that disease. We also explored the effects of raloxifene, an estrogen receptor modulator, on valvular calcification. Gene array analysis was performed in ...

Renal artery aneurysm is a rare entity, and patients are usually asymptomatic at the time of presentation. These aneurysms are rare among pregnant patients, especially after childbirth, and usually form due to changes in vascular wall integrity secondary to hormonal and hemodynamic changes. Here we describe a patient with an ...

Inferior mesenteric artery aneurysms are very rare and they are among the rarest of visceral artery aneurysms. Sometimes, the distribution of the blood flow due to chronic atherosclerotic occlusion of some arteries can establish an increased flow into a particular supplying district (high flow state). A high flow state in ...

ABSTRACT Inhalation injury frequently occurs in burn patients and contributes to the morbidity and mortality of these injuries. Arterial carboxyhemoglobin has been proposed as an indicator of the severity of inhalation injury; however, the interrelation between arterial carboxyhemoglobin and histological alterations has not yet been investigated. Chronically instrumented sheep were ...

Endovascular repair continues to pose a formidable technical challenge in the cases of aneurysm, dissection, and proximal type I endoleak involving the aortic arch. During the process of covering the aortic arch by stent graft to achieve better sealing, maintaining blood flow to the vital supra-aortic branches is difficult. We ...

Percutaneous coronary intervention has resulted in a paradigm shift in the treatment of coronary artery disease and myocardial infarction. However, neither bare-metal stents nor polymer-coated drug-eluting stents represent ideal therapies at this time due to the undesired in-stent stenosis or delayed thrombosis. Hence there is pressing clinical need for greater ...

OBJECTIVES: Bicuspid aortic valves are associated with aortic catastrophes, particularly dissection. We examined whether proactive repair of associated dilatation would reduce risk of subsequent aortic dissection or reoperation and whether more aggressive resection is needed in patients undergoing bicuspid aortic valve surgery alone. METHODS: From January 1993 to June 2003, ...
