超声心动图诊断单纯右肺动脉异常起源于升主动脉

目的 探讨单纯右肺动脉异常起源于升主动脉的超声心动图诊断价值.方法 回顾性分析5例单纯右肺动脉异常起源于升主动脉患者的超声心动图特征.结果 5例右肺动脉均起源于升主动脉近端左后壁,除合并动脉导管未闭外,无其他心内畸形;均存在重度肺动脉高压.3例手术,1例术前漏诊动脉导管未闭,1例院外多次彩色超声漏诊右肺动脉异常起源或误诊为大动脉转位.结论 单纯右肺动脉异常起源于升主动脉在解剖、血流动力学上有许多相似之处,把握共性并多部位、多切面探测有助于超声心动图作出准确诊断并减少漏、误诊.

Diagnosis of isolated anomalous origin of right pulmonary artery from ascending aorta by echocardiography

Objective To evaluate the value of echocardiography in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Methods The eehoeardiographie results of five patients with isolated anomalous origin of right pulmonary artery from ascending aorta were reviewed retrospectively. Results Severe pulmonary hypertension occurred in all the patients,besides accompanied with patent duetus arterious, no other congenital malformations combined. Three patients underwent operation. Patent ductus arterious was missed in one patient's diagnosis. Another patient was missed isolated anomalous origin of right pulmonary artery from ascending aorta in several echoeardiographic examinations, once misdiagnosed as complete transposition of the great arteries. Conclusions There are many anatomic and hemodynamic similarities in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Grasping their common charaeters and exploring multi-position and multi-section are helpful to make correct diagnosis.
