There are numerous mechanisms by which mammals respond to hypoxia. These include acute changes in pulmonary arterial tone due to smooth muscle cell contraction, acute increases in respiration triggered by the carotid body chemosensory cells, and chronic changes such as induction of red blood cell proliferation and angiogenesis by hypoxia inducible factor targets erythropoietin and vascular endothelial growth factor, respectively. Mitochondria account for the majority of oxygen consumption in the cell and have recently been appreciated to serve as signaling organelles required for the initiation or propagation of numerous homeostatic mechanisms...

Reports of involuntary ipsilateral movements after a stroke are rare, and none have described a patient with both an instinctive grasp reaction and tremor-like movement ipsilateral to the acute stroke lesion. We here report such a patient. A 76-year-old right-handed woman with a past history of left thalamic hemorrhage developed left hemiparesis, an instinctive grasp reaction, and a peculiar involuntary movement of her right arm. This involuntary movement was stereotyped and sometimes rhythmical, with a groping or picking-like action...

Present investigation evaluates the protective effect of Melilotus officinalis (MO) extract on the brain tissues in acute cerebral ischemia. Acute cerebral ischemia was induced by occlusion of carotid artery and rats with cerebral ischemia were treated with MO (100, 250 & 500mg/kg) for the duration of three days. Cerebral ischemia was confirmed by estimating infract volume and neurological deficit score. Moreover biochemical parameters in plasma such as 6-keto-PGF1α and TXB2 and concentration of cytokine, oxidative stress, apoptosis ratio and protein expressions of Bcl2 & Bax were estimated in the brain tissues...

The most effective treatment of patients with stroke due to tandem occlusion is still unclear. We report the case of a man with stroke due to tandem internal carotid artery/middle cerebral artery occlusion, who underwent initially ineffective intravenous thrombolysis (IVT) and endovascular treatment. Early anticoagulation with apixaban was started after 48 h of IVT, given a newly diagnosed nonvalvular atrial fibrillation. Spontaneous partial recanalization of the cervical internal carotid artery was noted, and carotid endarterectomy was performed 72 h after IVT and 8 h after the last dose of apixaban...

BACKGROUND: Tandem occlusions of the internal carotid artery (ICA) and middle cerebral artery (MCA) occur in up to a third of patients with acute ischemic strokes undergoing endovascular mechanical thrombectomy. Understanding open neurosurgical management of associated complications with this procedure is important. CASE REPORT: A 67-year-old man with acute onset of left hemiparesis and a tandem right ICA and MCA occlusion. He underwent carotid stent angioplasty of a stenotic ICA, followed by attempted Solitaire stent retrieval of an MCA clot...

BACKGROUND AND PURPOSE: Atrial fibrillation (AF) and significant carotid artery stenosis (CAS) often coexist in patients with acute stroke but whether CAS affects the stroke recurrence rate in anticoagulated AF patients is largely unknown. The effect of concomitant CAS on both short- and long-term prognosis after stroke in patients with AF was evaluated. METHODS: The multicentre, retrospective FibStroke registry included AF patients with an ischaemic stroke or transient ischaemic attack (TIA) during 2003-2012...

BACKGROUND AND PURPOSE: Although risk factors for acute coronary syndrome (ACS) and atherothrombotic cerebral infarction (ACI) are common, it is unknown if the risk factors for these two conditions are similar. The purpose of our study was to elucidate differences in carotid artery atherosclerotic features between ACS and ACI. METHODS: We measured carotid artery ultrasound-based atherosclerotic parameters in 61 ACS and 33 ACI patients. In the ACS patients, 31 had single-vessel coronary artery disease (SVD) and 30 had multivessel coronary artery disease (MVD)...

OBJECTIVE: Acute occlusions of the extracranial internal carotid artery (ICA) and a major intracranial artery respond poorly to intravenous tissue plasminogen activator (tPA) and present an endovascular challenge. The aim of our study was to retrospectively delineate the feasibility of the combined use of emergent carotid stenting and intra-arterial (IA) Abciximab with intracranial revascularization in the setting of acute ischemic stroke and carotid occlusions at our institution. METHODS: Eleven patients with complete cervical carotid occlusion with or without concomitant intracranial ICA and/or MCA occlusion were identified from a single center, retrospective review of patients admitted to the Stroke unit...

A novel vascular staple (C-staple) was developed that does not enter the vasculature lumen during anastomoses. The objective of this study was to demonstrate C-staple safety when used with a bovine xenograft and compare efficacy of the C-staple procedure with Anastoclip surgical clips or suturing when used with a bovine xenograft. Eight sheep had an acute comparison between suturing and C-staples using both common carotid arteries. Sixteen sheep had xenograft placement in the left carotid artery, eight with C-staples and eight with Anastoclips in a chronic study...

Blunt cerebrovascular injury (BCVI) to the carotid artery is a relatively rare injury that is difficult to identify even with imaging. Any symptoms or neurological deficits following blunt neck injury mandate evaluation and consideration of BCVI. In an effort to highlight this issue, we report the case of a 31-year-old male patient who presented with left-sided weakness consistent with transient ischemic attack (TIA) and concussion. The patient's symptoms occurred within 24 hours of a blunt neck injury sustained by a knee strike during a basketball game...

Mycotic aneurysms and prosthetic graft infections are traditionally treated with excision of the infected tissue or graft, often requiring anatomical or extra-anatomical bypass, carrying significant morbidity and mortality. Currently, the role of endovascular repair without excision in this setting has yet to be defined. We present two case scenarios whereby mycotic pseudoaneurysms were successfully treated with endovascular stent graft coverage, and to present an in-depth review of endovascular in-situ revascularziation in the treatment of arterial and graft infections...
