Tracheobronchial Release for Left Bronchus Compression After Aortic Arch Repair

Area of Science:

• Pediatric Cardiology
• Congenital Heart Surgery
• Thoracic Surgery

Background:

• Retroaortic space narrowing is a known complication after surgical repair of common arterial trunk (CAT) and interrupted aortic arch (IAA).
• This narrowing can lead to significant postoperative respiratory issues, particularly bronchial compression.
• Complex congenital heart disease, such as a functionally univentricular heart, presents unique surgical challenges.

Purpose of the Study:

• To report a case of successful management of left bronchus compression following CAT and IAA repair in a neonate with tricuspid atresia.
• To highlight the utility of tracheobronchial release in relieving postoperative airway obstruction in this specific patient population.

Main Methods:

• The patient, a newborn with CAT, IAA, and tricuspid atresia, underwent surgical repair.
• Surgical repair included CAT repair, IAA repair, and left ventricle-to-pulmonary artery (LV-to-PA) conduit placement using the Lecompte maneuver.
• Postoperative management involved identification and surgical release of left bronchus compression.

Main Results:

• The neonate developed left bronchus compression after the initial cardiac surgery.
• Tracheobronchial release was performed to alleviate the bronchial compression.
• The intervention successfully relieved the airway obstruction, leading to improved respiratory status.

Conclusions:

• The Lecompte maneuver, while effective for cardiac repair, can predispose to retroaortic space narrowing and bronchial compression.
• Tracheobronchial release is a viable and effective option for managing postoperative left bronchus compression in neonates after complex congenital heart defect repair.
• Careful postoperative monitoring and timely surgical intervention are crucial for patients undergoing complex cardiac surgeries with potential airway complications.
