摘要/Abstract

摘要： 本文探究右心声学造影结合经食道超声诊断中青年隐源性脑卒中的应用价值。选取240例疑似隐源性脑卒中中青年患者为研究对象，所有患者均进行右心声学造影和经食道超声检查，明确是否存在右向左分流，测量分流大小，并根据分流量进行分级。右心声学造影结合经食道超声诊断检出率高于单用右心声学造影、经食道超声诊断，具有统计学差异（P<0.05）。右心声学造影结合经食道超声检查诊断中青年隐源性脑卒中的灵敏度、准确度、特异度分别为91.61%、87.08%、80.41%。右心声学造影结合经食道超声检查可有效提高中青年隐源性脑卒中筛查的诊断灵敏度和准确度。

Abstract: This study explored the application value of right heart contrast echocardiography combined with transesophageal ultrasound in the diagnosis of cryptic stroke in young and middle-aged patients. 240 young patients with suspected cryptic stroke were selected as the research objects. All patients were examined by right heart contrast echocardiography and transesophageal ultrasound to determine whether there was a right-to-left shunt. Then measured the size of the shunt, and graded it according to the shunt flow. The detection rate of right heart contrast echocardiography combined with transesophageal ultrasound was significantly higher than that of right heart contrast echocardiography and transesophageal ultrasound alone (P<0.05). The sensitivity, accuracy and specificity of right heart contrast echocardiography combined with transesophageal ultrasound in the diagnosis of cryptic stroke in young and middle-aged patients were 91.61%, 87.08% and 80.41%, respectively. The right heart contrast echocardiography combined with transesophageal ultrasound examination can effectively improve the diagnostic sensitivity and accuracy of cryptic stroke screening in young and middle-aged people.

Key words: right heart contrast echocardiography, transesophageal ultrasound, young and middle-aged people, cryptogenic stroke
