目的探讨超声心动图在感染性心内膜炎赘生物及其他并发症中的诊断价值,为临床有效诊断提供依据。方法研究选取医院在2008年7月-2011年10月住院治疗的感染性心内膜炎患者76例,所有入组患者均行超声心动图、手术及病理检查,将检查结果进行统计分析。结果 76例患者行急诊手术4例占5.26%,择期手术72例占94.74%,手术成功74例占97.37%,死亡2例占2.63%;76例患者超声心动图检查发现赘生物35例,阳性率77.77%,赘生物<2mm有1例、2～15mm有31例、>15mm有3例;发现1个赘生物12例(其中4例为假阳性)、2个20例、≥3个3例;超声心动图检查受累瓣膜阳性率82.98%,其中二尖瓣受累26例、主动脉瓣受累23例、二尖瓣及主动脉同时受累9例、其他瓣膜受累3例,瓣周漏及脓肿各2例,瓣膜脱垂11例(其中2例为假阳性),瓣膜穿孔2例。结论超声心动图能对心脏赘生物进行准确定位,并能确定其大小、形态、数目及伴随的心脏情况,还能提供感染性心内膜炎有无心脏基础病变、并发症及相应的血流动力学改变等可靠的诊断依据,为临床提供详实的资料。
Objective To investigate the diagnostic value of echocardiography in infective endocarditis neoplasms and other complications and provide the basis for effective clinical diagnosis. METHODS: Totally 76 patients with infective endocarditis admitted to hospital from July 2008 to October 2011 were enrolled in this study. All patients underwent echocardiography, operation and pathological examination, and the results were analyzed statistically. Results 76 cases underwent emergency operation in 4 cases, 5.26% in elective surgery, 72 cases accounted for 94.74%, 74 cases were successful, accounting for 97.37%, 2 cases died of 2.63%; 76 cases of echocardiography found in 35 cases of neoplasms, positive Rate of 77.77%, 1 case of vegetation <2mm, 31 cases of 2 ~ 15mm, 3 cases of> 15mm; 1 case of neoplasm in 12 cases (4 cases were false positive), 2 cases of 20 cases, Cases; echocardiography examination valve positive rate of 82.98%, of which 26 cases of mitral involvement, aortic valve involvement in 23 cases, mitral and aortic involvement in 9 cases, other valve involvement in 3 cases, paravalvular leakage and abscess 2 cases in each, 11 cases of valve prolapse (2 cases were false positive), 2 cases of valve perforation. Conclusion Echocardiography can accurately locate the heart neoplasms, and can determine the size, shape, number and concomitant heart conditions, but also provide infective endocarditis with or without heart-based lesions, complications and the corresponding blood flow Dynamic changes and other reliable diagnostic basis for the clinical to provide detailed information.
