超声联合CT对缩窄性心包炎的诊断效能分析

Efficacy of Ultrasound Combined with CT in the Diagnosis of Constrictive Pericarditis

目的分析超声联合CT对缩窄性心包炎的诊断效能。方法选取2018年3月至2019年3月我院超声科68例拟诊为缩窄性心包炎患者,进行超声与CT检查,检查后对患者行心包剥脱术,术后将其病理组织送至实验室检查。观察超声与CT检查影像学表现,并比较两者诊断准确率。结果患者术后经病理检查后,共62例确诊为缩窄性心包炎。超声与CT检查结果显示,两者心包增厚、心包积液及下腔静脉增宽检出率差异无统计学意义(P>0.05)。超声心房增大、心室舒张功能下降及室间隔抖动征检出率高于CT(P<0.05);CT心包钙化检出率高于超声(P<0.05)。超声单独诊断准确率为75.81%,CT准确率为72.58%,两者联合准确率为91.94%。超声联合CT准确率高于两者单独检查结果(P<0.05)。结论超声可清晰观察到患者房室情况,CT为心包钙化的最佳观察方式,超声联合CT可有效提高缩窄性心包炎诊断准确率,及早确诊疾病并手术治疗,对提高患者预后具有重要价值,值得推荐。

Objective To investigate the efficacy of ultrasound combined with CT in the diagnosis of constrictive pericarditis.Methods 68 patients with constrictive pericarditis in our hospital from March 2018 to March 2019 were enrolled.All patients received the ultrasound and CT examinations.The pathological tissues were sent to the laboratory for examination after pericardiectomy.The imaging manifestations of two methods were observed,and the diagnostic efficacy for constrictive pericarditis was compared.Results 62 cases of constrictive pericarditis were diagnosed by postoperative pathology.The detection rate of pericardial thickening,pericardial effusion and inferior vena cava widening had no difference between two methods(P>0.05).The detection rate of atrial enlargement,ventricular diastolic function decline and ventricular septal jitter was higher by ultrasound than by the CT(P<0.05).The detection rate of pericardial calcification by CT was higher than that by ultrasound(P<0.05).The diagnostic accuracy of ultrasound,CT,and combined examination was 75.81%,72.58%and 91.94%.The accuracy of ultrasound combined with CT was higher than that of single examination(P<0.05).Conclusion Ultrasound can clearly observe the patient's atrioventricular condition,while CT is the best way to observe pericardial calcification,and the combination of two examinations can effectively improve the diagnosis accuracy of constrictive pericarditis.Early diagnosis and surgical treatment are of great value to improve the prognosis of patients.
