Background
Acute ischemic stroke secondary to aortic dissection (AoD) is challenging in the era of thrombolysis owing to the diagnostic difficulty within a narrow time window and the high risk of complications.Case Report
A 64-year-old woman with middle cerebral artery occlusion syndrome admitted to the emergency room within intravenous recombinant tissue plasminogen activator (rt-PA) time window. Her neurological symptoms improved during thrombolysis, but chest and abdominal pain developed. Repeated history-taking, physical examination, and imaging studies led to the timely diagnosis and surgical treatment of AoD, which produced a successful outcome.Conclusions
Clinical suspicion is invaluable for the diagnosis of this rare cause of stroke. Considering the stroke mechanism and complications, the risks of thrombolysis might outweigh its benefits. 相似文献2.

Background and Purpose
This work was undertaken to review the current cost-effectiveness analysis data on thrombolysis by intravenous (IV) therapy with recombinant tissue plasminogen activator (rtPA) for acute ischemic stroke.Methods
PubMed was searched for articles published between 1995 and 2008. The cost-effectiveness analysis data from eight eligible studies were reviewed, paying particular attention to their modeling assumptions and the quality of the source data.Results
The reviewed studies were from six countries: USA (n=2), UK (n=2), Canada (n=1), Australia (n=1), Spain (n=1), and Denmark (n=1); most were performed from the healthcare-system and/or societal perspectives. IV rtPA was associated with an acceptable increase in short-term cost [range: US$ 36-236/patient; US$ 29,148-55,591/quality-adjusted life-years (QALYs)], and a net long-term cost saving that was higher from a societal perspective (range: -US$ 12,043 to -US$ 630/patient; -US$ 207,253 to -US$ 21,938/QALYs) than from a healthcare-system perspective (range: -US$ 5,811 to -US$ 5,415/patient; -US$ 41,137 to -US$ 4,662/QALYs).Conclusions
IV rtPA seems to be a cost-effective strategy for the management of acute ischemic stroke, and might reduce the associated healthcare costs as well as patients'' disabilities. Further cost-effectiveness research and the development of a public health strategy are warranted to optimize the use of rtPA in Korea. 相似文献4.

OBJECTIVE: Intravenous recombinant tissue plasminogen activator (rt-PA) is the only therapy of proven value for patients with acute ischemic stroke (AIS). Controversy exists with regard to the prognostic significance of early computed tomography (CT) changes in patients receiving rt-PA for AIS. The authors retrospectively reviewed all cases of AIS who received intravenous rt-PA for AIS in University of South Alabama hospitals between January 1996 and May 1999. A neuroradiologist, blinded to clinical outcomes, reviewed all baseline CT scans for the presence of the following signs: hyperdense middle cerebral artery (HMCA), loss of gray-white differentiation (LGWD), insular ribbon sign (IRS), parenchymal hypodensity (PH), and sulcal effacement (SE). Modified Rankin Scale (mRS) score was recorded 90 days after thrombolysis, and clinical outcome was dichotomized as favorable (0-1) or unfavorable (2-6). The authors performed both univariate and multivariate analyses to investigate the relationship between early CT signs, baseline clinical variables, and functional outcome as measured by the 90-day mRS scores. Any one early CT finding was detected in 23(64%) patients. The frequency of specific findings were as follows: SE in 13 patients (36%), LGWD in 12 patients (33%), PH in 9 patients (25%), HMCA in 4 patients (11%), and IRS in 3 patients (8%) patients. There was no statistically significant association between the occurrence of these imaging findings and subsequent functional outcome after thrombolysis. The data suggest that the presence of subtle acute CT changes in AIS patients is not predictive of clinical outcome following administration of rt-PA as per National Institute of Neurological Disorders and Stroke protocol. 相似文献

Extracranial Internal Carotid Artery Occlusion: The Role of Common Carotid Artery Volume Flow 总被引:1,自引:0,他引:1
Teng-Yeow Tan MD Ulf Schminke MD Li-Ming Lien MD B. Martin Eicke MD Charles H. Tegeler MD 《Journal of neuroimaging》2002,12(2):144-147
BACKGROUND AND PURPOSE: Quantitative measurement of blood flow volume in the common carotid artery (CCA) is now possible using the color velocity imaging quantification (CVI-Q) ultrasound technique. The aim of this study was to evaluate the cerebral hemodynamic effects of unilateral internal carotid artery (ICA) occlusion on CCA blood flow volumes (FVs) using CVI-Q. METHODS: Records of ultrasound studies in our neurosonology laboratory were retrospectively reviewed to identify patients with unilateral ICA occlusions who at a minimum received both a routine color duplex carotid ultrasound examination and quantitative measurement of FV in the CCA, bilaterally, using the CVI-Q method. A total of 71 patients met criteria and were included in the cohort. A side to side comparison was performed for FV, peak systolic velocities (PSV), end-diastolic velocities (EDV), and resistance indices (RIs) in the CCA. Results correlated with any other available data such as flow direction in the ophthalmic artery and the presence of intracranial collateralization. RESULTS: The FV, PSV, and EDV were significantly reduced, and the RI was significantly increased in the CCA on the side of the occlusion. A subgroup analysis in patients who also had an examination of the ophthalmic (n = 61) and the intracranial arteries of the Circle of Willis (n = 50), showed significantly higher FV in the CCA on the side of the occlusion if there was also reversed flow in the ophthalmic artery on the side of the occlusion (344 +/- 144 ml/min versus 169 +/- 53 ml/min). CONCLUSION: Quantitative FV measurement using CVI-Q ultrasound can identify clear alterations in volume flow, collateral pathways, and cerebral hemodynamics in patients with unilateral ICA occlusion. It is a complementary tool, providing additional objective information about the cerebral hemodynamic effects of ICA occlusion that goes beyond what is available using routine flow velocity data. 相似文献

Background: Intravenous recombinant tissue plasminogen activator (IV rt-PA) prior to thrombectomy may reduce the risk of intraprocedural distal embolization in acute ischemic stroke patients. Methods: We analyzed the diffusion-weighted imaging acquired with 1.5- or 3-T magnetic resonance imaging (MRI) scans obtained within 24 hours of thrombectomy in consecutive acute ischemic stroke patients. An independent physician identified distal embolization, defined as discrete foci of restricted diffusion independent of the primary area of infarction on MRI scan. Patients were stratified based on whether they had or did not receive IV rt-PA prior to thrombectomy. Results: Distal embolization was seen in 59 (ipsilateral in 56) of 63 patients (mean age ± SD; 64.6 ± 15.3 years) who underwent thrombectomy (mean number 8.6; range 0-32). There was no difference in mean number of ipsilateral hemispheric distal embolization between the 2 groups (7.9 ± 6.1 versus 7.5 ± 7.6, P = .82). After adjusting for age, admission National Institutes of Health Stroke Scale score, the time interval between symptom onset and thrombectomy, there was no association between receiving IV rt-PA prior to thrombectomy and number of ipsilateral distal emboli (P = .90). There was no relationship between the number of ipsilateral emboli and rates of favorable outcome after adjusting for other confounders (adjusted odds ratio 1.0; 95% confidence interval .89 - 1.0; P = .40). Conclusions: Although distal embolization is very common after thrombectomy, IV rt-PA prior to procedure does not reduce the risk of intraprocedural distal embolization. 相似文献
