Background: Preoperative diagnosis of extra-cardiac malformations is essential for surgical planning. Computed tomography (CT) cardiac angiography plays an essential role in CHD, especially for assessing the extra-cardiac manifestations of CHD. Complex cardiovascular anatomic features and extra-cardiac manifestations identified with CT angiography are sometimes more useful in decision-making in surgical procedures.
Methods: This prospective study was conducted in the Department of Radiodiagnosis at Benha university hospital Cases were selected randomly from Pediatric patients with known congenital cardiac disease for extracardiac anomalies work up in the department of jan 2021 to may 2024, 50 consecutive patients (male 23, female 27); with age ranging from 4 months to 11 years were diagnosed with congenital complex cardiac malformations on echocardiography with suspected intrathoracic extra-cardiac vascular anomalies, All the angiogram was done with All CT examinations were performed using Multi Detector CT.
Results: Patent ductus arteriosus (PDA) emerged as the most frequently observed anomaly, accounting for 20% of cases, followed by coarctation of aorta (16%)MAPCAS (14%) and,, PAPVR (14%), , transposition of the great arteries (10%), DORV (8%), right-sided aortic arch (10%), and double superior vena cava (10%). Less frequently encountered anomalies included anomalies in the origin of coronary arteries represented (6%), , hypoplastic aortic arch (12%), , interrupted aortic arch (8%), TAPVR (8%), aberrant left subclavian artery (6%), pseudocoarctation (4%), truncus arteriosus (4%), double aortic arch (4%)
Conclusion: Multislice CT angiography is helpful in accurate diagnosis of confident diagnosis and anatomic detection of extra-cardiac vascular abnormalities and coronary arteries anomalous origin compared with echocardiography.
