Physician-Modified Branched Double-Trunk Stent-Graft (PBDS) for Thoracoabdominal Aortic Aneurysm.

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.
