Atrioesophageal fistula is a rare but potentially fatal complication of ablation of atrial fibrillation developing up to 60-days post-ablation with a prevalence of 0.07% to 0.25%, and a 63% mortality. While chest CTs are abnormal in most of these patients (76%-93%), definitive atrioesophageal fistula is noted in only 23-35% of cases, complicating pre-intervention diagnosis. Surgical repair of the left atrial and primary esophageal defect is essential for these patients, resulting in reduced mortality compared to nonsurgical management (33.71% vs. 94.19%). Methods: Our case series and comprehensive review of the literature highlights the diagnostic and treatment challenges of atrioesophageal fistula. Results/Conclusions: For symptomatic patients within 60-days post-ablation, IV contrast-enhanced helical chest CT with thin section collimation as initial imaging and axial reconstruction utilizing a 1mm-mm detector with sagittal and coronal reformats should be completed to allow for optimal identification of abnormalities consistent with atrioesophageal fistula. Patients with neurologic symptoms with the presence of pneumocephalus, infarcts involving one or more vascular territories, or diffuse air emboli that are highly suggestive of atrioesophageal fistula, warrant a chest CT with IV contrast to evaluate the presence of AEF. An initial unremarkable chest CT does not rule out atrioesophageal fistula and repeat chest CT with IV contrast within 1-3 days increases the likelihood of a definitive AEF diagnosis. Surgery is the only recommended management in patients with atrioesophageal fistula who are clinically stable enough to endure the procedures.","PeriodicalId":178697,"journal":{"name":"American Journal of Diagnostic Imaging","volume":"484 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132288177","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}

Data was utilized from 50 total subjects (31 females and 19 males) with an average age of 25.90 ± 4.54 years between the ages of 18-45 were measured via Real-time Ultrasound and images were taken in side-lying 4 times. Digital measurements were taken from the peak of the spinous processes of L4-L5 and L5-S1. The distance of each segment was measured in millimeters in each position of neutral side-lying and follow a flexion/ extension PIVM. Descriptive statistics were used to summarize data and presented as mean ± SD. An independent sample t test was used to compare the mean age, and baseline (neutral) interspinous distance measurements between female and male subjects. P value was set at 0.05 and all of the comparisons were two-tailed. Repeated measures ANCOVAs on interspinous space between L4-5 and L5-S1 before-after the flexion and extension PIVMs were made by including covariates gender, height, and age. The measured interspinous distances between L4-L5 (F=128.58, df=1,48, p<0.001, ηp2=0.728. p<0.001) and L5-S1 (F=168.27, df=1,48, p<0.001, ηp2=0.778) were significantly higher following the flexion PIVM compared to neutral 1. The measured interspinous distances between L4-L5 (F=72.821, df=1,48, p<0.001, p<0.001, ηp2=0.603) and L5-S1 (F=113.358, df=1,48, p<0.001, ηp2=0.703) were significantly lower following the extension PIVM than neutral 2. Gender (F=0.878, df=4,44, p=0.485) and height (p=0.799) were not significantly associated with those above-mentioned changes. However, age was found to be significantly related to L4-L5 flexion (F=7.38, df=1,47, p=0.009, ηp2=0.136). The direction of relation between age and L4-L5 flexion (β=0.351, t= 2.60, p=0.013, p=0.013) was positive and linear. After controlling for age, there were significant changes in L5-S1 flexion (F=6.168, df=1,47, p=0.017, ηp2=0.116) and extension (F=8.321, df=1,47, p=0.006, ηp2=0.150). During a flexion and extension PIVM there were statistically significant changes in interspinous movement regardless of the subjects’ gender and height, and age. These findings validate the changes in interspinous distance during a lumbar PIVM technique through objective imaging with RTUS and provide baseline data for future research to identify if lower spinal dysfunctions will ultimately result in any changes to the resting position of interspinous spaces and during flexion or extension PIVMs.","PeriodicalId":178697,"journal":{"name":"American Journal of Diagnostic Imaging","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114890448","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}

The inclusion of coronal STIR sequences in routine scans could increase the diagnostic sensitivity enabling earlier diagnosis and hence decreasing the morbidity and mortality. The objective of this study is to evaluate additional benefit of a coronal STIR during routine MR of cervical spine. \u0000Materials and Methods: \u0000A retrospective review of 8224 MR scans performed in a year at two imaging diagnostic centres in India was carried out. There were 512 cervical spine MR scans, which were analysed to delineate additional findings solely identified on coronal STIR sequences. The routine protocol included axial and sagittal T1 and T2 sequences and coronal STIR images. \u0000Results: \u0000There were positive findings solely demonstrated on coronal STIR sequences in 32 cases. These include 16 cases of non-specific brachial plexopathy, 4 cases of lung malignancy, 7 cases of lymphadenopathies and 5 cases of tuberculosis of apical segments. \u0000Conclusion: \u0000Due to its large field of view, fluid sensitivity and short acquisition time, coronal STIR sequences, could be very helpful in deciphering additional findings which otherwise would be missed. The inclusion of this sequence in routine scans could significantly increase the diagnostic capability that might change the patient’s management in a significant proportion of cases, at low cost.","PeriodicalId":178697,"journal":{"name":"American Journal of Diagnostic Imaging","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121452894","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}
