MSCTA在肺动脉分支起源异常及合并畸形中的应用价值
Application value of MSCTA in pulmonary artery branch origin anomalies and associated malformations
摘要
Abstract
Objective:To explore the application value of MSCTA in the diagnosis of abnormal origin of pulmonary artery and associated malformations.Methods:A retrospective study was conducted on 46 patients with abnormal origin of pulmonary artery confirmed by surgery or DSA in our hospital from May 2018 to November 2025.Their MSCTA images and three-dimensional post-processing images were collected,and the diagnostic accuracy of MSCTA for abnormal origin of pulmonary artery and associated malformations was analyzed.Results:Among the 46 patients,13 had unilateral pulmonary artery originating from the ascending aorta(11 right,2 left),with 84.6％(11/13)being the proximal type(near the aortic valve);13 had pulmonary artery sling,and 20 had unilateral pulmonary artery agenesis.Surgery or DSA confirmed 82.3％(38/46)of patients had 110 associated malformations.The most common intracardiac malformation was atrial septal defect(ASD,38,34.5％),and the most common vascular malformation was patent ductus arteriosus(PDA,19,17.3％).Other associated malfor‑mations included pulmonary hypoplasia(7,6.4％),tracheal stenosis(6,5.5％),bronchial developmental variation(1,2.6％),and 1 case of rare Berry syndrome.The overall detection rate of abnormal origin of pulmonary artery by MSCTA was 93.5％(43/46),and the diagnostic accuracy for associated cardiovascular malformations was 92.7％(102/110).Missed or misdiagnosed cases were mainly those with pulmonary artery ostium adjacent to other vessels or tiny intracardiac malformations.Conclu-sion:abnormal origin of pulmonary artery is a rare congenital disease,often accompanied by ASD,PDA,pulmonary hypopla‑sia and other malformations.MSCTA can provide accurate anatomical descriptions and identify related abnormalities,which provides key imaging evidence for clinical treatment planning.关键词
