Aberrant Right Subclavian Artery with Kommerell's Diverticulum and Patent Ductus Arteriosus: Unusual Combination of Congenital Heart Anomalies and Clinical Manifestations in A Neonate

Background: A one-month-old neonate presented to the hospital with dyspnea and bloody stool, which happened suddenly and progressed over two days. Case presentation: Computed tomography and threedimensional reconstruction of the trachea and heart was done, demonstrating significant trachea stenosis, aberrant right subclavian artery arising from Kommerell's diverticulum, and patent ductus arteriosus. Reconstruction of the aberrant subclavian artery, resection of the diverticulum, and ligation of ductus arteriosus was performed. Conclusion: The case reported a rare combination of congenital anomalies and rare clinical manifestations at the same time. We thought the anatomical anomalies caused necrotizing enterocolitis (NEC), which lead to bloody stool.

Automated summary

This is a rare case of congenital anomalies and clinical manifestations in a newborn. Computed tomography and three-dimensional reconstruction revealed tracheal stenosis, aberrant right subclavian artery, and patent ductus arteriosus. The anatomical anomalies may have caused necrotizing enterocolitis, leading to bloody stool.
