【摘要】 目的:提高对慢性缩窄性心包炎的临床及影像学特征的认识能力,降低误诊率。方法:分析41例慢性缩窄性心包炎的临床表现,影像学特征。结果:临床表现为不同程度的呼吸困难、心悸、浅静脉充盈,心尖搏动减弱、奇脉、脉压差小。影像学表现:超声心动图检查:心室舒张末径缩小者33例,24例于M型超声心动图上见左室后壁在舒张中晚期运动停止呈平直外形。X线检查:心影轻中度扩大者32例,25例出现心包钙化,26例出现肺淤血,肺部有结核病灶者23例。CT可明确显示心包增厚及钙化。结论:慢性缩窄性心包炎的影像学特征是一侧或两侧心缘僵直,搏动减弱,心包膜增厚、钙化,心室缩小,小心室大静脉。更多还原

【Abstract】 Objective:To improve the cognitive ability of chronic constrictive pericarditis,Reduces misdiagnosing rate.Methods:The review analysis 41 examples chronic constrictive pericarditis the clinical manifestation,the image studyCharacteristic.Results:The clinical manifestation for varying degree having difficulty in breathing,the palpitation,the shallow vein fulls.heart pulsates weakens,the arteries differential pressure is small.Image study performance:33exams Ventricle diastole Diameter Reduces in Ultrasonic cardiogram Inspection.24 exams left ventricle wall stop moving in mid and later period presents Straight contour in M image.32 exams heart Light moderate expansion in X ray inspection.25 exams Pericardium calcification.26 exams Lung extravasated blood.23 exams Pulmonary tuberculosis.CT may be clear about the demonstration pericardium thick and the calcification.Conclusion:The imaging character of chronic constrictive pericarditis is tetanicing with one or both of the heart surface,pulsates weakens.Pericardium thick and calcification.ventricles small.Small ventricle Big Vein.更多还原
