Endothelins are important vasoconstrictors and cellular-growth promoters. ETA-specific antagonists have been shown to reduce neointimal response to injury in some experimental angioplasty models. However, there is little information on the effects of dual ETA/ETB receptor blockers, such as bosentan, on neointimal proliferation following experimental coronary angioplasty. Coronary injury was achieved ...

Blunt pelvic and perineal trauma has been previously reported to result in site-specific veno-occlusive dysfunction and/or site-specific cavernosal artery insufficiency. We herein describe a case of erectile dysfunction in a young previously potent amputee. We postulate that the erectile dysfunction is associated with a newly described form of blunt trauma, ...

Traumatic rupture of the thoracic aorta is a life threatening situation, and may be secondary to several mechanisms; mainly penetrating or iatrogenic lesions and blunt trauma. Although penetrating mechanisms predominate, the number of patients with aortic disruption due to blunt trauma has continued to increase. This paper shows an overview ...

Recent studies have revealed the role of the pRb family members pRb and p130 in the response to vascular injury. We evaluated the arterial injury response in the absence of p107, a protein that shares a high degree of homology with the injury-controlling p130. Carotid artery ligation and perivascular electric ...

BACKGROUND: Our purpose was to determine the accuracy of single-injection, retrograde transbrachial arteriography (RTBA), performed in the emergency room, for suspected axillosubclavian injuries. METHODS: Thirty-three patients were prospectively assigned for RTBA. Clinical indications for RTBA included high-risk mechanism of injury, decreased (n = 19) or absent (n = 5) brachial ...

Complete common femoral artery transection from blunt trauma without bony injury is a rare event. Below we report upon a young cyclist who sustained complete transection of the common femoral artery following blunt trauma. The patient was managed successfully by graft repair of the transected artery. This case report highlights ...

Electrical burns cause damage to the cardiovascular system through different mechanisms. Immediate cardiac arrhythmia is one of the common consequences. A large vessel blow out due to an electrical burn is rarely documented. It is often undetected due to its "silent" symptoms. This article reports a delayed obturator artery rupture ...

OBJECTIVE: It has become clear that von Willebrand factor (vWF) plays important roles in platelet adhesion and aggregation under high blood-flow velocity conditions observed in stenotic atherosclerotic arteries. However, its roles in thrombus formation in vivo on diseased arteries have not been fully understood. We examined the contribution of vWF ...

Intercostal pulmonary herniation occurring years after blunt thoracic trauma is a rare phenomenon. We report on the case of a 66-year-old patient who developed a pulmonary herniation 2 years after a seat-belt injury. Thoracotomy was performed, and the thoracic wall defect was closed with approximating periostal absorbable sutures. The postoperative ...

Restenosis after percutaneous coronary intervention continues to be a serious problem in clinical cardiology. Recent advances in nanoparticle technology have enabled us to deliver an antiproliferative drug selectively to the balloon-injured artery for a longer time. NK911, which is a core-shell nanoparticle of polyethyleneglycol-based block copolymer encapsulating doxorubicin, accumulates in ...

In the usual method of brain removal in forensic autopsies, the upper bridging veins were invariably torn. There are several types of head injuries, in which ruptures of these vessels are the predominant intracranial injury. For the past 5 years we have investigated nearly all cases of lethal head injuries ...

Inflammatory reactions occurring in the brain after ischemia may contribute to secondary damage. In the present study effects of minocycline, an anti-inflammatory agent, alone or in combination with mild hypothermia, on focal embolic brain ischemia have been examined. Focal ischemic injury was induced by embolizing a preformed clot into the ...

In standard blepharoplasty, the orbital septum is opened commonly to enter the preaponeurotic space. This is to anchor the leading edge of the levator palpebral fascia to the skin of a proposed supratarsal fold and to remove supraorbital fat. Incision of the orbital septum is involved occasionally with accidental injury ...

BACKGROUND: The mechanisms responsible for the association between advanced age and atherosclerotic diseases are not clear. Because atherosclerosis develops in response to local endothelial injuries, we investigated the effect of aging on vascular healing and reendothelialization. METHODS AND RESULTS: Endothelium denudation was performed by balloon angioplasty of the iliac arteries ...

Heme oxygenase (HO) is a cytoprotective enzyme that degrades heme (a potent oxidant) to generate carbon monoxide (a vasodilatory gas that has anti-inflammatory properties), bilirubin (an antioxidant derived from biliverdin), and iron (sequestered by ferritin). Due to the properties of inducible HO (HO-1) and its products, we hypothesized that HO-1 ...

When vascular injury is observed in dogs used in preclinical toxicology studies, careful evaluation of the lesions is warranted, especially when differentiating drug-induced vascular changes from spontaneous findings, such as idiopathic canine polyarteritis. The clinical signs as well as the nature and distribution of lesions can often be distinguishing, as ...

Blunt carotid artery injury is an uncommon injury with a potentially devastating outcome. Although treatment is often unhelpful for an established neurologic deficit, there is frequently a delay between the episode of trauma and the onset of neurology. This delay provides a window of opportunity where early detection and intervention ...

Matrix metalloproteinases (MMPs) and, in particular, MMP-9 are important for smooth muscle cell (SMC) migration into the intima. In this study, we sought to determine whether MMP-9 is critical for SMC migration and for the formation of a neointima by using mice in which the gene was deleted (MMP-9(-/-) mice). ...
