OBJECTIVE P-selectin-mediated leukocyte-endothelium and leukocyte-platelet interaction has been reported after vascular injury and has been correlated with neointimal hyperplasia, but its role in neointimal formation after arterial injury in diabetes has not been described. METHODS AND RESULTS Using a Zucker diabetic rat balloon injury model, we examined the role of P-selectin in the vascular...
Percutaneous iliosacral screw fixation is commonly practiced to treat unstable posterior pelvic ring injuries. The number of reported cases of iatrogenic complications is increasing. We present a case of superior gluteal artery injury during bilateral percutaneous iliosacral screw fixation in a patient with sacral fracture of spino-pelvic dissociation. This complication was managed by arterial ...
Vascular injury from an arterial closure device.
BACKGROUND Intimal injury rapidly activates TGFβ and enhances vascular repair by the growth of endothelial (EC) and vascular smooth muscle cells (VSMC). The response to the TGFβ family of growth factors can be modified by BAMBI (BMP, Activin, Membrane Bound Inhibitor) acting as a non-signaling, competitive antagonist of TGFβ type I receptors such as ALK 1 and 5. In vivo the effect of BAMBI will...
Peripheral vascular injuries are frequently encountered traumas that require emergency intervention. Rapid recognition of injury, fluid replacement, blood transfusion, and early revascularization very critical in the potential prevention mortality, extremity loss, functional defect. In present report, we aimed to emphasize importance arterial superficial venous also deep revascularizations on m...
Accumulating evidence suggests that urokinase plasminogen activator (uPA) is involved in vascular remodeling and lumen stenosis after angioplasty and stenting. We have shown previously that increased uPA expression greatly promotes neointima formation and inward arterial remodeling after balloon injury. To evaluate the role of inflammation in early mechanisms responsible for inward arterial rem...
BACKGROUND Aging-associated changes in the cardiovascular system increase the risk for disease development and lead to profound alterations in vascular reactivity and stiffness. Elucidating the molecular response of arteries to injury and age will help understand the exaggerated remodeling of aging vessels. METHODOLOGY/PRINCIPAL FINDINGS We studied the gene expression profile in a model of me...
OBJECTIVE Cerebral critical closing pressure (CCP) has been defined as an arterial pressure threshold below which arterial vessels collapse. Hypothetically this is equal to intracranial pressure (ICP) plus the contribution from the active tone of cerebral arterial smooth muscle. The correlation of CCP with ICP, cerebral autoregulation, and other clinical and haemodynamic modalities in patients ...
Popliteal artery injuries are frequently seen with fractures, dislocations, or penetrating injuries. Concern about arterial injury and early recognition of the possibility of arterial injury is crucial for the salvage of the extremity. This article provides an outline of the diagnostic challenges related to these rare vascular injuries and emphasizes the necessity for a high level of suspicion,...
OBJECTIVE Core2 1 to 6-N-glucosaminyltransferase-I (C2GlcNAcT-I) plays an important role in optimizing the binding functions of several selectin ligands, including P-selectin glycoprotein ligand. We used apolipoprotein E (ApoE)-deficient atherosclerotic mice to investigate the role of C2GlcNAcT-I in platelet and leukocyte interactions with injured arterial walls, in endothelial regeneration at ...
