Abstract

Objective: To present our surgical experience and evaluate the therapeutic strategy for cases of right aortic arch associated with Kommerell's diverticulum treated by open surgical repair at Cho Ray Hospital.


Methods: A descriptive case series study was conducted from 2020 to 2025 at Cho Ray Hospital on patients with right aortic arch associated with Kommerell's diverticulum who were indicated for open surgical repair.


Results: Four patients underwent successful open repair via median sternotomy, with complete excision of the diverticulum and aortic reconstruction using a graft. The mean cardiopulmonary bypass time was 220 ± 40 minutes. No operative or early postoperative mortality occurred. One elderly patient developed postoperative pneumonia requiring prolonged tracheostomy. The remaining patients recovered well, with marked improvement in compressive symptoms and satisfactory graft patency on postoperative computed tomography imaging. The patient with prior hybrid repair deteriorated due to worsening bronchial compression from the stent-graft, and the family declined re-operation


Conclusion: Open surgical repair remains a mainstay of treatment for right aortic arch associated with Kommerell's diverticulum, particularly in patients with complex anatomy, large aneurysms, or significant mediastinal compressive symptoms. This approach enables thorough relief of mediastinal compression and ensures long-term patency of the reconstructed aorta.
