background chlamydia pneumoniae has been linked with increased risk of cardiovascular diseases; however, data on stroke and cerebrovascular accidents are sparse. objectives the aim of this study was to determine the association between c. pneumoniae infection and ischemic stroke. patients and methods in a case-control study, 141 patients, admitted with ischemic stroke, were compared with gender...
Abstract Background Recently published randomized controlled trials (RCT) have questioned the utility of Fraction Flow Reserve (FFR) to guide revascularization in patients with multivessel coronary artery disease (CAD) as compared Angiography Purpose This current analysis aimed compare clinical outcomes associated FFR guided versus standard angiography-guided for CAD using a large number stable...
common anomalies of the carotid-basilar anastomoses. Persistent trigeminal artery variants originate directly from the precavernous portion of the internal carotid artery (ICA) and may be observed, usually as an incidental finding, in 0.1-1% of angiography or non-invasive vascular imaging studies.1 Little is known about the significance of the PPTA in occlusive cerebrovascular disease. We descr...
Abstract Funding Acknowledgements Type of funding sources: None. Background Acute coronary syndrome (ACS) remains a frequent cause hospital admission, with its prognosis depending on many factors, one being the location culprit lesion. It is established that anterior myocardial infarction, caused mostly by left descending artery occlusion associated worse and higher morbimortality. Therefore, i...
BACKGROUND AND PURPOSE The ability to identify patients at increased risk for stroke from cerebral hemodynamic ischemia may help guide treatment planning. We tested the correlation between regional cerebrovascular reserve (rCVR) on acetazolamide-challenged single-photon emission CT (SPECT) brain scans and intracranial collateral pathways as well as extra- or intracranial (EC-IC) arterial stenos...
PURPOSE To retrospectively evaluate the complications of diagnostic cerebral catheter angiography in 19,826 consecutive patients. MATERIALS AND METHODS This HIPAA-compliant study had institutional review board approval, with waiver of informed consent. Demographic, procedural, and complication data in 19 826 consecutive patients undergoing diagnostic cerebral angiography at one institution fr...
BACKGROUND AND PURPOSE Catheter-based cerebral angiography remains an important diagnostic tool in the pediatric population, particularly considering the currently growing interest in diagnosing and treating cerebrovascular disorders in children. There are no recent estimates of the complication rate associated with modern diagnostic digital subtraction angiography (DSA) in the pediatric popula...
A total of 72 ocular bruits in 50 patients with symptoms of atherothrombotic ischemic cerebrovascular disease were studied with continuous-wave Doppler ultrasonography with spectrum analysis (Dopscan). Fourteen patients also had conventional angiography, and 14 had digital subtraction angiography. Ocular bruits by augmentation flow due to occlusion (seven bruits, 9.7%) or tight stenosis (17 bru...
BACKGROUND AND PURPOSE To develop recommendations for the establishment of comprehensive stroke centers capable of delivering the full spectrum of care to seriously ill patients with stroke and cerebrovascular disease. Recommendations were developed by members of the Brain Attack Coalition (BAC), which is a multidisciplinary group of members from major professional organizations involved with t...
BACKGROUND Moyamoya syndrome is a vasculopathy characterised by progressive occlusion of the cerebral arteries resulting in the development of abnormal collateral circulation. To diagnose this syndrome, imaging of the cerebral arteries is required including CT- or MR-angiography and conventional angiography. We present a case of moyamoya disease with typical findings detected in the sonography....
