Summary
Kommerell diverticulum repair is complex. This study presents a novel single-stage hybrid frozen elephant trunk technique for treating Kommerell diverticulum and aberrant right subclavian artery during acute aortic dissection.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Kommerell diverticulum treatment typically requires complex, multistage surgical repair.
- Repair involves excluding the diverticulum, dividing the vascular ring, and reconstructing the aberrant subclavian artery.
- Emergency presentations, especially with acute aortic dissection, pose significant surgical challenges.
Observation:
- A patient presented with acute type A aortic dissection and Kommerell diverticulum.
- The complexity of the condition necessitated an innovative surgical approach.
Findings:
- A novel, single-stage approach was successfully employed.
- This involved using a multibranched hybrid arch frozen elephant trunk prosthesis.
- The technique achieved complete repair of the Kommerell diverticulum and aberrant right subclavian artery.
Implications:
- This single-stage hybrid frozen elephant trunk technique offers a potentially less invasive and more efficient solution for complex Kommerell diverticulum cases.
- It demonstrates the feasibility of managing acute aortic dissection with concurrent Kommerell diverticulum repair.
- This approach may improve outcomes for patients with this challenging combined pathology.
