Background: Prior studies suggest that patent foramen ovale (PFO) diameter >4 mm is associated with a high probability of cryptogenic ischemic stroke (CIS). Methods: We evaluated all patients diagnosed with CIS who underwent closure of intra-atrial communication (IAC) using the Amplatzer atrial septal defect (ASD) occluder in our institution between August 1997 and March 2004. For each IAC, echocardiographic diameters and balloon-stretched diameters were recorded. Stretchability index was calculated as the ratio of stretched diameter to unstretched diameter. Results: Fifty-six patients met the inclusion criteria for this study. There was an inverse logarithmic relationship between unstretched IAC diameter and stretchability index. For the 28 smaller defects, the median IAC diameter was 2 mm, and median stretchability index was 5.58 (range 2.6–15). For the 28 larger defects, median diameter was 6 mm, and median stretchability index was 2.38 (range 1.05–5). The difference in stretchability index between the two groups was significant ( P < 0.0001). Conclusion: Our data bring into question the concept that the diameter of the defect would singularly predict the probability of stroke. 相似文献

Electro-clinical characteristics and postoperative outcome of medically refractory tumoral temporal lobe epilepsy 总被引:1,自引:0,他引:1

BACKGROUND: Very few studies have specifically addressed surgical treatment and outcome of patients with tumor-related temporal lobe epilepsy (TLE). AIM: To define the postoperative seizure outcome and the factors that influenced the outcome of patients with tumor-related TLE. MATERIALS AND METHODS: We selected patients whose surgical pathology revealed a temporal lobe neoplasm and who had completed > 1 year of postoperative follow-up. We reviewed the clinical, EEG, radiological and pathological data, and the seizure outcome of these patients and assessed the factors that influenced the outcome. RESULTS: Out of the 409 patients who underwent surgery for refractory TLE during the 8-year study period, there were 34 (8.3%) patients with temporal lobe neoplasms. The median age at surgery was 20 years and the median duration of epilepsy prior to surgery was 9.0 years. MRI revealed tumor in the mesial location in 21 (61.8%) patients. Interictal and ictal epileptiform EEG abnormalities were localized to the side of th lesion in the majority. Mesial temporal lobe structures were included in the resection, if they were involved by the tumor; otherwise, lesionectomy alone was performed. During a median follow-up of 4 years, 27 (79%) patients were completely seizure-free. The only factor that predicted long-term seizure-free outcome was being seizure-free during the first two postoperative years. CONCLUSIONS: Our results emphasize the fact that in patients with tumoral TLE, when the seizures are medically refractory, surgery offers potential for cure of epilepsy in the majority. 相似文献

BACKGROUND: Despite new therapies, the prevalence of heart failure continues to escalate. The prevalence of diabetes, a risk factor for heart failure, also continues to rise. To further understand the increasing prevalence of heart failure, we compared trends in the prevalence of diabetes among individuals with diagnosed heart failure versus those in the general population. METHODS: Fourteen randomized trials between 1989 and 1999 including subjects with heart failure (n = 34,633) were reviewed. For each trial, the enrollment date was used to estimate the yearly prevalence of diabetes among study participants with heart failure. The prevalence of diabetes in the general population was estimated based on United State's Center for Disease Control statistics from 1989 to 1999. The prevalence of diabetes between heart failure subjects and the general population was compared using a two-sample t-test for independent samples with unequal variances. RESULTS: The prevalence of diabetes increased from 2.6% to 4.0% from 1989 to 1999 in the general U.S. population. Among patients with heart failure, the prevalence of diabetes increased from 13% to 47%. Diabetes prevalence estimates varied significantly (p < 0.001) between the general population and individuals with heart failure during the study period. CONCLUSIONS: The rising prevalence of diabetes may partially explain the growing epidemic of heart failure. Increased efforts targeting diabetes and other cardiovascular risk factors are warranted in attenuating the rising prevalence of heart failure. 相似文献

MR imaging features of mitochondrial encephalomyopathies, lactic acidosis, and stroke-like episodes, Kearns-Sayre/Pearson syndrome have been described in the literature. We describe extensive white matter changes with abnormal signal intensity lesions involving the deep gray nuclei and myelinated white matter tracts in an 18-year-old female with a large-scale 7.4 kb mitochondrial DNA deletion and a atypical presentation of Kearns-Sayre syndrome. Restricted diffusion due to status spongiosus at the involved sites is also discussed. 相似文献

The percutaneous approach for RF ablation of liver lesions high up in the dome is always difficult. The authors describe a transpulmonary approach that may be simpler and safer to use. 相似文献

A case of tuberous sclerosis (TS) with classic triad of seizures, mental deficiency and angiofibromas is presented. The child also presented with self-mutilating behavior, which resulted in the fracture of her anterior teeth. A comprehensive treatment was rendered to the patient under general anesthesia and a mouth guard was given to prevent further trauma to the teeth. 相似文献
