Pedunculated thrombus in the aortic arch that is associated with cerebral infarction is very rare requires prompt diagnosis and treatment to prevent occurrence of another devastating complication. Transesophageal echocardiography is useful for detecting source of embolism including aortic thrombi. The treatment options of aortic thrombi involves anticoagulation, thrombolysis, thromboaspiration, and thrombectomy. Here we report a case of huge thrombus in the aortic arch, resulting in acute multifocal cerebellar embolic infarct in patient without any risk factors for vascular thrombosis. Thrombi in the aortic arch were diagnosed by transesophageal echocardiography and treated with anticoagulants successfully.
Insulin autoimmune syndrome (IAS) is characterized by fasting hypoglycemia, endogenous hyperinsulinemia, and the presence of autoantibodies to insulin or insulin receptor in patients that have never been exposed to exogenous insulin. This syndrome is occasionally accompanied by several autoimmune disorders. There is no reported case of concurrent IAS with Hashimoto's thyroiditis. A 52-year-old female was diagnosed with Hashimoto's thyroiditis and was treated with 25 μg/d levothyroxine for 3 years. Recently, she experienced recurrent fasting hypoglycemic symptoms that disappeared rapidly with a carbohydrate-rich diet, although she had no history of diabetes or insulin use. Blood analysis showed hypoglycemia and elevated serum levels of insulin and C-peptide. Imaging studies did not reveal a mass lesion in the pancreas, and selective calcium-stimulated venous sampling also gave a negative result. However, anti-insulin antibody titer was high and assay for anti-insulin receptor antibody was positive. Here, we report a case of IAS concomitant with Hashimoto's thyroiditis. 이 그레이브스병과 동반되어 나타난 예를 처
-AbstractPolyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that typically affects the medium-sized muscular arteries, with occasional involvement of the small muscular arteries.As with other vasculitides, PAN can affect any organ system, including the cardiovascular, gastrointestinal and central nervous systems. The prognosis for patients with untreated PAN is relatively poor, with five-year survival rates of approximately 13 percent. The outcome has improved with proper therapy to approximately 80 percent survival at five years.We report here on a case of a 46 year old man with polyarteritis nodosa and who suffered from pulmonary tuberculosis.
-AbstractBackground:The occurrence of atrial fibrillation after ablation of atrial flutter is clinically important. We investigated variables predicting this evolution in ablated patients without a previous atrial fibrillation history.Materials and Methods:Thirty-six patients (Male=28) who were diagnosed as atrial flutter without previous atrial fibrillation history were enrolled in this study. Group 1 (n=11) was defined as those who developed atrial fibrillation after atrial flutter ablation during 1 year follow-up. Group 2 (n=25) was defined as those who has not occurred atrial fibrillation during same follow-up term. Echocardiogram was performed to all patients. We measured left atrial size, left ventricle end diastolic and systolic dimension, ejection fraction and left atrial volume index before and after ablation of atrial flutter. The differences of each variables were compared and analyzed between two groups. 1)Results:The preablation left ventricular ejection fraction (preLVEF) and postablation left ventricular ejection fraction (postLVEF) are 54±14%, 56±13% in group 1 and 47±16%, 52±13% in group 2. The differences between each two groups are statistically insignificant (2.2±1.5 in group 1 vs 5.4±9.8 in group 2, p=0.53). The preablation left atrial size (preLA) and postablation left atrial size (postLA) are 40±4 mm, 41±4 mm in group1 and 44±8 mm, 41±4 mm in group 2. The atrial sizes of both groups were increased but, the differences of left atrial size between two groups before and after flutter ablation were statistically insignificant (0.6±0. Conclusion:The difference between left atrial volume index before and after atrial flutter ablation is the robust predictor of occurrence of atrial fibrillation after atrial flutter ablation without previous atrial fibrillation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
