All 19 patients were diagnosed using digital subtraction angiography. CUS parameters, including the end-diastolic ratio of the common carotid artery (CCA-ED ratio), end-diastolic flow velocity of the external carotid artery (ECA EDV), and the resistance index of the external carotid artery (ECA RI), were examined before and after treatment of CS-dAVF and TS-dAVF. A comparison of the CUS parameters before treatment showed increases in the CCA-ED ratio and ECA EDV and a decrease in the ECA RI in TS-dAVF patients. After treatment, the difference in the changes in TS-dAVF vs. CS-dAVF patients was significant. Thus, compared with before treatment, the CCA-ED ratio (pre: 1.80 vs. post: 1.38, p = 0.005) and ECA EDV (cm/s) (54.4 vs. 29.9, p = 0.001) decreased significantly in TS-dAVF patients, whereas the ECA RI was significantly higher in both TS-dAVF (0.60 vs. 0.72, p = 0.005) and CS-dAVF (0.76 vs. 0.85, p = 0.043) patients. These results demonstrated the utility of CUS in estimating the therapeutic effect of dAVF, especially in patients with TS-dAVF. dural arteriovenous fistula (dAVF), cavernous sinus dural arteriovenous fistula (CS-dAVF), transverse sigmoid sinus dural arteriovenous fistula (TS-dAVF), resistance index (RI)","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"291 1","pages":"129-132"},"PeriodicalIF":0.1,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76312689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dilatation of left atrium dimension (LAD) and increased levels of brain natriuretic peptide (BNP) are reported to indicate cerebral embolism due to PAF. We assessed the usefulness of chest X-ray in predicting LAD and BNP among patients with acute cerebral infarction. Methods: We included 141 consecutive patients with cerebral infarction [107 cerebral thromboses (cerebral thrombosis group)] and 34 cardiogenic cerebral embolisms due to PAF (PAF group). Transthoracic echocardiography (TTE) was used to evaluate LAD (TTE-LA). On chest X-ray, heart diameter at the third aortic arch (XPLA) and XP-LA divided by maximum intrathoracic diameter (XP-LA ratio) were measured. Results: TTE-LA, XP-LA, XP-LA ratio and BNP levels were significantly higher in PAF group compared with those in cerebral thrombosis group. XP-LA had a significant positive correlation with TTE-LA (r = 0.332, p < 0.0001) and BNP (r = 0.292, p < 0.001). XP-LA ratio also showed a significant correlation with TTE-LA (r = 0.210, p = 0.0126) and BNP (r = 0.515, p < 0.0001). Conclusion: We suggest chest X-ray is a simple and useful tool for predicting LAD and BNP.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"95 1","pages":"38-42"},"PeriodicalIF":0.1,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78176436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We included consecutive 183 patients of brain infarction on which both carotid ultrasonography and ABI/baPWV was performed from July 2014 to June 2015. We evaluated the mean/max intima-media thickness (IMT), plaque score, LDL cholesterol, HDL cholesterol, D-dimer, NT-proBNP, eGFR, HbA1c, and ABI/ baPWV. In ABI, we used the lower side of the ankle and divided into two groups: ABI < 0.9 and ABI ≥ 0.9. In baPWV, we used the higher side and divided into two groups: baPWV > 1,983cm/s and baPWV ≤ 1,983cm/s. Results: Among the 99 patients diagnosed with cardioembolic infarction, atherothrombotic infarction, or lacunar infarction, neither carotid ultrasonography nor ABI/baPWV was associated with stroke subtypes. However, among the 84 patients diagnosed with an unclassified or other etiology, 9 were diagnosed with aortogenic cerebral embolism. A multivariate analysis showed that aortogenic cerebral embolism was significantly associated with the mean IMT and ABI. Conclusion: Among unclassified or other etiology stroke patients, mean IMT and ABI are suggested for the diagnosis of aortogenic cerebral embolism.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"213 1","pages":"133-138"},"PeriodicalIF":0.1,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76134013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
