Popis: Background Patent ductus arteriosus (PDA) is one of most common congenital heart defects, it's a unique vascular structure that provides direct communication between pulmonary and systemic circulation. MDCT angiography is a good imaging modality for evaluation of the PDAs and detection of their exact morphological type; course and diameters, which is important before percutaneous closure or stenting procedure of the PDA, also for selection of closure hardware. The aim of this study was to assess the role of MDCT angiography in qualitative and quantitative evaluation of PDA and associated cardiac and\or extracardiac anomalies. Results Echocardiography detected PDA in 28\30 cases while cardiac MDCT detected PDA in all studied 30 cases confirmed by cardiac catheterization and/or operation. MDCT angiography had sensitivity 100% and specificity 100% for PDA detection. PDA originated from aortic isthmus in 15 cases, inferior surface of aortic arch in 11 cases and innominate artery in 4 cases. The most common morphological type of PDA was type A (cone\46.67%) followed by type C (tubular\23.3%), type D (complex\10%), type E (elongated\13.33%) and type B (window\6.67%). The spearman correlation coefficient test demonstrated poor correlation between size of aortic end and MPA (P = 0.75), and between size of pulmonary end and diameter of MPA (P = 0.99) and also demonstrated fair correlation between length of PDA and MPA (P = 0.018). PDA was isolated in 4\30 cases and associated with cardiac and\or extra cardiac anomalies in 26\30 cases included; ASD (n = 18), VSD (n = 16), pulmonary atresia (n = 7), transposition of great arteries (n = 5), teratology of Fallot (n = 4), aortic coarctation (n = 4), persistent truncus arteriosus (n = 3), tricuspid atresia (n = 3), anomalous of pulmonary venous return (n = 3), hypoplastic segment of aorta (n = 2), Ebstein's anomaly (n = 1), bicuspid aortic arch (n = 1) and left hypoplastic heart syndrome (n = 1). Conclusion Cardiac MDCT angiography was superior to Echocardiography in detection, quantitative and qualitative evaluation of PDA either isolated or associated with congenital cardiac and\or extracardiac anomalies and was superior to Echocardiography in detection of associated extracardiac anomalies rather than associated intra cardiac anomalies.
