摘　　要：感染性心内膜炎是由病原体感染心内膜所致,容易累及心脏瓣膜,其特征性病损为赘生物形成,而赘生物脱落可以引起动脉栓塞并造成重要组织器官的缺血、坏死等。中国人民解放军总医院确诊了1例感染性心内膜炎合并多发心外并发症,其特征性影像学表现为超声检查发现二尖瓣前叶赘生物形成,CT、MRI检查发现多发脏器、血管受累,具体表现为脾梗死、肾脏梗死、脑梗死、脾动脉瘤、肠系膜上动脉瘤、肾动脉瘤及右侧大脑中动脉远端管腔狭窄、闭塞。Infective endocarditis is a microbial infection of the endocardium and can easily affect heart valve.Its characteristic lesion is vegetation formation,and the shedding of vegetation results in arterial embolism and ischemic necrosis of corresponding tissues and organs.A case of infective endocarditis with multiple extracardiac complications was described in this article.The characteristic ultrasound finding was the vegetation formation in anterior mitral valve.CT and MRI scans revealed involvements in multiple organs and blood vessels,which were manifested as splenic infarction,renal infarction,cerebral infarction,splenic aneurysm,superior mesenteric artery aneurysms,renal artery aneurysms,and distal segment stenosis and occlusion of right middle cerebral artery.
