..., access to neuroangiography suite and a sizeable support team including angiography nursing, radiographers and anaesthetists [ 10, 11 ]. The maintenance of such a system requires a centralized approach and high volume of cases for skills maintenance [ 11, 12 ]. This has important implications for stroke...

.... However, work-up in an MSU that includes CT angiography (CTA) may also potentially facilitate triage of patients directly to the appropriate target hospital and specialized treatment, according to their individual vascular pathology. Methods: Our institution manages a program investigating the prehospital...

... Angiography The connection between leptomeningeal collateral flow (LMF) and survival of brain parenchyma during acute ischemia has been confirmed in a large number of clinical studies [ 1,2,3,4,5,6,7,8,9 ]. Better collateral flow is associated with smaller infarct volumes, less hemorrhagic...

... of consecutive patients admitted for stroke or transient ischemic attack (TIA) with symptomatic intracranial stenosis confirmed by digital subtraction angiography in a single-center retrospective study. Angiograms were graded systematically in a blinded fashion for antegrade and collateral flow, using...

.... A total of 1,304 patients who underwent MSCT coronary angiography and cerebral angiography were included in this study. By using 64-multislice computed tomography coronary angiography, we investigated the frequency of CAD and association between coronary and cerebral artery atherosclerosis in terms...

.... Methods: In 30 patients (18 females/12 males, age 8–63 years), standardized revascularization was performed. Digital subtraction angiography was performed preoperatively and at 7 days, 6 months and 12 months postoperatively. STA-MCA and EMS functions were graded I (poor), II (medium) or III (extensive...

... digital subtraction angiography. Methods: In this randomized, double-blind, prospective study, pre- and postangiographic diffusion-weighted magnetic resonance imaging (DWI) of 184 participants was evaluated for the occurrence of silent embolism. Results: No significant relationship was found between...

..., 16 (27%) the shift and 22 (37%) the dilatation pattern on angiography. There was excellent agreement between the 2 neuroradiologists (ĸ =0.681). Cross-tabulation analysis showed that angiographic pattern was significantly associated with gender (p = 0.007), symptom pattern (TIA vs. stroke, p = 0.001...

Methods: Twenty-three moyamoya disease patients with ischemic presentation who received revascularization with complete angiography and xenon CT during a minimum of 3 years’ clinical follow-up were enrolled...

... putaminal hemorrhage without remarkable subarachnoid hemorrhage. Most patients were evaluated using conventional catheter angiography except for hypertensive patients over the age of 60 who underwent a magnetic resonance angiogram or a computed tomography angiogram. Computed tomography and clinical factors...

...Kiyohiro Houkin; Naoki Nakayama; Satoshi Kuroda; Tadashi Nonaka; Takaharu Shonai; Takashi Yoshimoto Background: Magnetic resonance angiography (MRA) has been acknowledged as a noninvasive diagnostic modality for moyamoya disease. However, in terms of staging of moyamoya disease, conventional...

... the angiographic and transcranial Doppler ultrasonography (TCD) findings of calcified cerebral arteries. Methods: The subjects were 57 patients with ischemic stroke, all of whom underwent brain CT, digital subtraction cerebral angiography and TCD. Stroke subtypes were defined according to TOAST classification. Two...

... in asymptomatic populations. Early carotid arterial wall disease is also a useful predictor of coronary artery disease on angiography and subsequent coronary vascular events in populations at risk of coronary heart disease. More advanced carotid wall disease (carotid stenosis and plaque surface morphology...

...–13.6, p < 0.001). Conclusions: Ulceration of carotid plaques, visible on angiography or on pathological examination, is seen most often in the proximal (upstream) part where shear stress is highest. To determine whether the frequency of plaque rupture varies along the longitudinal axis...

.... Angiography Atherosclerosis Carotid arteries Blood flow In both the carotid and the coronary circulations, acute thrombotic and thromboembolic events are usually due to unstable atherosclerotic plaque [ 1, 2, 3, 4, 5, 6 ]. However, it is uncertain which factors influence the stability of plaques...

... was to assess the validity of color Doppler sonography compared to selective intra-arterial angiography in the quantification of proximal vertebral artery stenoses. Materials and Methods: A prospective blind study of 316 vertebral arteries was undertaken between 1996 and 1998. One hundred and fifty-eight...
