The mechanisms of the motion of the intimal flap and of thrombus formation in acute or chronic aortic dissection are not definitively elucidated. Transesophageal echocardiography seems to be a technique of choice to analyze the flow in the true and false lumina. Twenty-one consecutive patients were studied in order to define the mobility of the intimal flap, the color Doppler flow patterns, the presence of spontaneous echocardiographic contrast, and thrombus formation at different levels of the aorta. The results suggest that clotted false lumen is more often seen in chronic aortic dissection at the level of the descending thoracic aorta. However, thrombosed false lumen in the aortic arch is suggestive of a retrograde aortic dissection. In cases of complete obliteration of the false lumen, the differentiation between aortic dissection and aortic ectasia with mural thrombus may be extremely difficult. 相似文献

Cardiovocal syndrome (Ortner’s syndrome) is characterized by left recurrent laryngeal nerve palsy due to cardiovascular disease, but in rare cases it can also be caused by aortic dissection. An 81-year-old man with hypertension was admitted to the hospital with aspiration pneumonia. He had been developing progressive dysphagia and hoarseness for several months before admission. A videofluoroscopic swallowing study showed supraglottic penetration with barium paste and liquid. Laryngoscopy and electromyography revealed left vocal cord palsy caused by left recurrent laryngeal neuropathy, and a contrast-enhanced chest CT revealed dissection of the aortic arch.No commercial party having a direct financial interest in the results of the research supporting this article has or will confer a benefit upon the authors or upon any organization with which the authors are associated. 相似文献

Acute aortic dissection is the most common catastrophic condition of the aorta. Treatment options include open surgery and thoracic endovascular aortic reconstruction (TEVAR). We present a late Type A dissection as a complication of the management of descending aortic dissections with TEVAR and a review of the literature. TEVAR of the thoracic aorta is a viable treatment option for the management of complicated descending thoracic aortic dissections. Careful patient selection is necessary as medical therapy successfully treats the majority of uncomplicated Type B dissections. TEVAR should be reserved for patients with complicated Type B dissections or those who fail nonoperative management. Close postoperative monitoring is necessary when TEVAR is performed and should be accompanied by lifelong surveillance. A high level of suspicion is important to identify retrograde Type A dissections in these patients given its rarity and the ambiguity of its clinical presentation. 相似文献

Cushing''s syndrome and Cushing''s disease cause various metabolic disorders associated with high cortisol levels. Some reports have shown that Cushing''s syndrome is complicated with dissecting aortic aneurysm and aortic dissection after long-term exposure to high cortisol levels. We herein report a rare case of aortic dissection complicated with Cushing''s disease. Aortic dissection may occur even under relatively short periods of high cortisol conditions. This case suggests that hypercortisolemia should be treated as soon as possible in order to prevent aortic dissection in subjects with Cushing''s disease. 相似文献

Spontaneous coronary artery dissection is a rare but increasingly recognized cause of acute myocardial ischemia in young adults, especially in women. We report a case of spontaneous coronary dissection in a young healthy man who was also a carrier of the factor V Leiden gene mutation. 相似文献

INTRODUCTION/AIMS
We designed an interactive web module to improve medical student competence in screening and interventions for hazardous drinking. We assessed its impact on performance with a standardized patient (SP) vs. traditional lecture.SETTING
First year medical school curriculum.PROGRAM DESCRIPTION
The web module included pre/posttests, Flash©, and text didactics. It centered on videos of two alcohol cases, each contrasting a novice with an experienced physician interviewer. The learner free-text critiqued each clip then reviewed expert analysis.PROGRAM EVALUATION
First year medical students conveniently assigned to voluntarily complete a web module (N = 82) or lecture (N = 81) were rated by a SP in a later alcohol case. Participation trended higher (82% vs. 72%, p < .07) among web students, with an additional 4 lecture-assigned students crossing to the web module. The web group had higher mean scores on scales of individual components of brief intervention (assessment and decisional balance) and a brief intervention composite score (1–13 pt.; 9 vs. 7.8, p < .02) and self-reported as better prepared for the SP case.CONCLUSIONS
A web module for alcohol use interview skills reached a greater proportion of voluntary learners and was associated with equivalent overall performance scores and higher brief intervention skills scores on a standardized patient encounter.KEY WORDS: health education, alcohol use disorders/alcoholism, Internet, multimedia learning 相似文献9.

Discontinuities between the leaflets of the aortic and left atrioventricular valves are uncommon congenital malformations. The anomaly may be discovered during surgery without preoperative diagnosis. It represents a spectrum of anomalies that result from interruption of the normal development of the endocardial cushions during the fetal life. We describe a rare case of Down syndrome with transient complete atrioventricular block and discontinuity between the leaflets of the aortic and left atrioventricular valves without intervening fibrous band, leading to separation and detachment between them. It caused severe eccentric jet of regurgitation originated from left ventricular outflow tract and base of anterior leaflet of left atrioventricular valve into the left atrium. He underwent cardiopulmonary bypass, and the defect between left atrioventricular valve and aortic annuli was sewn. Permanent epicardial pacing was inserted during cardiac surgery. To the best of our knowledge, such a case has not been previously reported in the literature. 相似文献
