Abstract:
Purpose Unilateral absence of pulmonary artery is a rare congenital pulmonary arterydysplasia whose untypical symptom often leads to missed diagnosis or misdiagnosis.Diagnostic and follow-up values of ultrasound cardiogram to pediatric congenital unilateral absence of pulmonary artery (UAPA) are explored in this paper.Materials and Methods Ultrasound cardiogram images of 35 UAPA patients confirmed by surgery or CT angiography in Guangzhou Women and Children's Medical Center from May 2009 to July 2016 were analyzed retrospectively,and images characteristics of the correctly diagnosed and missed diagnosis or misdiagnosed ultrasound cardiogram were analyzed.Results Among these 35 UAPA patients,21 cases were on the right side,14 cases on the left side,16 cases single UAPA and 19 cases combined with other intracardiac malformations.27 cases were initially diagnosed by ultrasound cardiogram,7 cases were missed diagnosed and 1 case misdiagnosed,with 77.1％ diagnosis accuracy.UAPA ultrasound cardiogram showed that normal bifurcation structure of pulmonary artery disappears.Main pulmonary artery continued to be one-side pulmonary artery,running to left or right and forming left branch or right branch of pulmonary artery.Pulmonary artery of the one-side absence of pulmonary segment supplied blood through aorta or other branches or vessels on the other side.After receiving unilateral pulmonary artery reconstruction surgery,ultrasound cardiogram of 8 patients of one month indicated that average flow rate of close-end anastomosis was (1.22± 0.17) m/s and far-end (2.17± 0.56) m/s.Conclusion Ultrasound cardiogram is efficient for UAPA preoperative diagnosis.Meanwhile,it is convenient,noninvasive and efficient in assessing anastomosis and pressure of pulmonary artery after surgery.
