Although the pathophysiology of post-angioplasty restenosis has been extensively studied in extracranial arteries using transluminal vascular injury model in rodents, it is still not well known in the intracranial arteries, which have quite different structures from extracranial arteries. Here, we examined whether 1-min placement of modified intraluminal suture could induce ...

Iatrogenic injury to the circumflex coronary artery following mitral annuloplasty is a potentially fatal complication. It can be clinically silent or else be responsible for a cardiogenic shock. The diagnosis should be suspected on EKG changes with segmental dysfunction of the lateral wall on the intraoperative echography. The author reports ...

A patient with an axillary artery gunshot wound pseudoaneurysm was evaluated and managed with computed tomographic angiogram and endovascular stent graft. Vascular injuries resulting from penetrating trauma or interventional vascular procedures are relatively uncommon. Subclavian and axillary arterial injuries may be associated with substantial morbidity and mortality if not managed ...

BACKGROUND: Transcatheter balloon aortic valvuloplasty for critical aortic stenosis in neonates is routinely performed without recognized complication. Aortic wall injury has rarely been observed after balloon aortic valvuloplasty, although the incidence of this complication is unstudied. We reviewed single-center data to determine the incidence of aortic injury during balloon aortic ...

Penetrating injuries may infrequently cause pseudoaneurysms, lacerations and arteriovenous fistulas involving the subclavian artery. These injuries present with life-threatening bleedings, associated regional injuries and critical limb ischemia and although surgery has been considered the treatment of choice, subclavian injuries pose a real surgical challenge. We prospectively examined data of six ...

Incidental arterial injury is one of the main mechanical complications associated with central venous catheter placement. These injuries can result in significant morbidity and mortality. The use of arterial closure devices to repair these injuries offers a less invasive alternative than open repair and a safer approach than manual compression. ...

Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is a membrane protein that can support the binding, internalization, and proteolytic degradation of oxidized low-density lipoprotein. The LOX-1 expression increases in the neointima after balloon injury. To develop an efficient compound to inhibit LOX-1, we designed and synthesized a novel gene silencer pyrrole-imidazole ...

Inflammation plays a major role in vascular disease. We have shown that leukocyte infiltration and inflammatory mediator expression contribute to vascular remodeling after endoluminal injury. This study tested whether increasing protein O-linked-N-acetylglucosamine (O-GlcNAc) levels with glucosamine (GlcN) and O-(2-acetamido-2-deoxy-d-glucopyranosylidene) amino-N-phenylcarbamate (PUGNAc) inhibits acute inflammatory and neointimal responses to endoluminal arterial ...

The most commonly used procedures to induce arterial injury in mice are carotid artery ligation with cessation of blood flow and mechanically-induced denudation of endothelium in the carotid or the femoral arteries. Both procedures result in neointimal hyperplasia after two to three weeks. A survey of various inbred strains of ...

Flail chest is most often accompanied by a significant underlying pulmonary parenchymal injury and can be a life-threatening thoracic injury. Its management is often complicated by the other injuries it is frequently associated with. Similarly, mortality and morbidity are dictated most often by the associated injuries and findings. Its treatment ...

Injury to the axillary artery is a rare complication of anterior shoulder dislocation. Open surgical repair is technically demanding because of the anatomical position of the vessel and the propensity for concomitant injuries. Standard surgical exposure techniques involve extensive dissection, including a combination of supraclavicular or infraclavicular incision, median sternotomy, ...
