Extremely rarely, a posterior communicating artery (PCoA) of "duplicate origin" occurs when two branches of the PCoA arise separately from the supraclinoid segment of the internal carotid artery (ICA) and quickly fuse to form an arterial ring. Three such cases previously reported were described as "fenestration." We report the case ...

Rotational vertebral artery occlusion, or bow hunter's stroke, is reversible, positional symptomatic vertebrobasilar ischemia. The typical mechanism of action is obstruction of a dominant vertebral artery with contralateral head rotation in the setting of baseline ipsilateral vertebral artery stenosis or occlusion. Here we present a rare case of mechanical occlusion ...

Transcatheter aortic valve implantation (TAVI) has been introduced as an alternative to conventional surgery for high-risk patients with aortic stenosis. A recently published randomized clinical trial demonstrated reduction of mortality in high-risk or inoperable patients when compared to medical treatment or balloon aortic valvuloplasty. Despite this evidence of superiority, the ...

The traumatic rupture of the thoracic aorta is a severe and life-threatening entity. The incidence of penetrating trauma to the aortic arch is not known, because most patients die of haemorrhage even before they receive adequate treatment. Clinical signs of such injuries include external or internal haemorrhage, bruit, distal pulse ...

Hyperhomocysteinemia confers a high risk for thrombotic vascular events, but homocysteine-lowering therapies have been ineffective in reducing the incidence of secondary vascular outcomes, raising questions regarding the role of homocysteine as a mediator of cardiovascular disease. Therefore, to determine the contribution of elevated homocysteine to thrombosis susceptibility, we studied Cbs(-/-) ...

ABSTRACT: Bronchial circulation plays a critical role in the pathophysiology of burn and smoke inhalation-induced acute lung injury. A 10-fold increase in bronchial blood flow is associated with excessive production of nitric oxide (NO) following smoke inhalation and cutaneous burn. Because an increased release of neuropeptides from the airway has ...

Vascular complications are a major concern during transcatheter aortic valve replacement, and can occur independently of introducer size. Arterial and venous access must be meticulous in order to avoid potentially life-threatening bleeding, which most commonly results from injury to the common femoral or iliac arteries. We report an unusual case ...

A 61-year-old woman underwent celiac trunk stenting to treat abdominal angina. Three months later, she was readmitted for recurrent symptoms. Computed tomography control revealed the migration of the stent into the splenic artery. No sign of vessel injury or end-organ ischemia was detected. Repeat stenting of the celiac trunk was ...

Following recent successes with percutaneous coronary intervention (PCI) for treating coronary artery disease (CAD), many challenges remain. In particular, mechanical injury from the procedure results in extensive endothelial denudation, exposing the underlying collagen IV-rich basal lamina, which promotes both intravascular thrombosis and smooth muscle proliferation. Previously, we reported the engineering ...

There is no good animal model of large artery injury-induced intimal hyperplasia (IH). Those available are reproducible, providing only a few layers of proliferating cells or have the disadvantage of the presence of a metallic stent that complicates histology evaluation. This study was designed to develop a new, simple model ...
