Purpose: To describe the preliminary experience of using physician-modified, branched, double-trunk stent-grafts (PBDS) for treating thoracoabdominal aortic aneurysms (TAAA).
Materials and methods: Ten (10) patients with TAAA were included in the study from June 2017 to March 2020. The technical success, perioperative complications, re-intervention, and patency of branch arteries were assessed.
Results: The technical success rate was 100%. There were four type III endoleaks (40%) recorded in the perioperative period. The median follow-up was 13.4 months (range, 3-36 months). During follow-up, two renal stent-graft occlusions (2 of 37 visceral arteries reconstructed, 5.4%), one cerebral infarction (1 of 10, 10%) and one paraplegia (1 of 10, 10%) occurred. No aortic-related death was recorded.
Conclusion: PBDS is useful in sealing TAAA and preventing visceral branches, providing an option for patients unsuited for open surgical repair. A larger sample size of patients is required to confirm the safety and effectiveness of this technique.
