【摘要】：目的:探讨多普勒超声心动图对肺动脉吊带(PAS)的诊断价值,分析超声心动图漏误诊的原因,提高超声心动图对PAS诊断的准确性。方法 :本文回顾性分析62例经外科手术证实为PAS患儿的超声心动图检查资料。结果 :62例PAS中,完全性PAS 59例,部分性PAS 3例;单纯性PAS 14例,合并其他心血管畸形者48例。62例患儿中,超声诊断正确55例(占88.7%),漏误诊7例(占11.3%)。7例漏误诊患者中,3例超声诊断为左肺动脉缺如,2例诊断为左肺动脉发育不良,1例诊断为原发性肺动脉高压伴三尖瓣轻度反流,1例诊断为法洛四联症、左肺动脉不能显示。62例患者中57例行心脏CT检查,心脏畸形与外科手术发现均相同,诊断符合率100%;CT诊断气道狭窄51例,气道狭窄超声心动图检查均未显示。结论:超声心动图可以比较准确地诊断PAS,但易漏误诊;在正常左肺动脉起始处若未发现左肺动脉,要警惕PAS的存在;必要时应行心脏CT检查,明确诊断及有无气管狭窄存在。
[Abstract]:Objective: to investigate the diagnostic value of Doppler echocardiography in pulmonary artery sling (Pass), analyze the causes of misdiagnosis of echocardiographic leakage, and improve the accuracy of echocardiography in the diagnosis of PAS. Methods: the data of echocardiography in 62 children with PAS confirmed by surgery were analyzed retrospectively. Results of 62 cases of PAS, 59 were complete PAS, 3 were partial PAS, 14 were simple PAS and 48 were complicated with other cardiovascular malformations. 55 cases (88.7%) were correctly diagnosed by ultrasound, 7 cases (11.3%) were misdiagnosed as missing diagnosis. 3 cases were diagnosed as missing left pulmonary artery and 2 cases were diagnosed as left pulmonary artery dysplasia. 1 case was diagnosed as primary pulmonary hypertension with tricuspid valve light. A case of tetralogy of Fallot was diagnosed. In 57 cases of left pulmonary artery failure, cardiac malformations were found to be the same as surgical findings. The diagnostic coincidence rate was 100% CT in 51 cases of airway stenosis, and none of them was detected by echocardiography. Conclusion: echocardiography can accurately diagnose pass, but it is easy to miss misdiagnosis. If left pulmonary artery is not found at the beginning of normal left pulmonary artery, we should be alert to the existence of PAS. If necessary, we should perform cardiac CT examination to make sure the diagnosis and the existence of trachea stenosis.
