Aortopulmonary Window or Patent Ductus Arteriosus? The Window Ductus

Area of Science:

• Cardiology
• Thoracic Surgery
• Pediatric Surgery

Background:

• Window Ductus (type B) is a rare congenital anomaly with unique anatomy.
• Its presentation can mimic a typical patent ductus arteriosus, leading to diagnostic and surgical challenges.
• Misdiagnosis can result in surgical misadventure if approached with standard patent ductus arteriosus techniques.

Purpose of the Study:

• To report a case of Window Ductus diagnosed in infancy.
• To describe the diagnostic and surgical management of this rare anomaly.
• To highlight an effective surgical repair strategy.

Main Methods:

• Diagnosis confirmed via advanced cross-sectional imaging (CT scan).
• Surgical repair performed via median sternotomy with cardiopulmonary bypass.
• Specific surgical technique involved aortic-side clamping, division, primary aortic cuff closure, and autologous pericardial patch for the pulmonary artery.

Main Results:

• Successful surgical repair of the Window Ductus.
• Resolution of symptoms including recurrent upper respiratory tract infections and complete left lung collapse.
• Complete reexpansion of the left lung post-repair.

Conclusions:

• Window Ductus requires careful diagnostic evaluation, with CT scans being crucial for surgical planning.
• Median sternotomy and cardiopulmonary bypass provide a safe and reproducible surgical approach.
• This approach facilitates successful repair and favorable patient outcomes.
