The neo-modified Cabrol technique demonstrated favorable perioperative and mid-term outcomes for patients with root-involved type A aortic dissection. This surgical approach ensures safe coronary artery reconstruction and effective long-term perfusion.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Surgery
Background:
- Stanford type A aortic dissection involving the aortic root presents challenges in coronary artery reconstruction, impacting perioperative safety and long-term perfusion.
- Evaluating the outcomes of the neo-modified Cabrol technique against the original Bentall procedure is crucial for root-involved dissections.
Purpose of the Study:
- To assess the efficacy and safety of the neo-modified Cabrol technique in patients with type A aortic dissection and aortic root involvement.
- To compare the outcomes of the neo-modified Cabrol technique with the original Bentall procedure.
Main Methods:
- A retrospective single-center cohort study included 398 patients (December 2012-June 2023) undergoing either neo-modified Cabrol (349 patients) or original Bentall (49 patients) repair.
- Propensity score analysis with overlap weighting was used to balance baseline characteristics.
- Primary endpoint was 30-day all-cause mortality; secondary endpoints included overall survival and coronary interposition graft complications.
Main Results:
- Thirty-day mortality was comparable: 7.2% for neo-modified Cabrol and 8.2% for original Bentall.
- Median follow-up was 4.23 years for neo-modified Cabrol and 11.48 years for original Bentall, with 100% follow-up.
- Survival rates at 1, 5, and 10 years were favorable for neo-modified Cabrol (89.4/85.7/82.5%) compared to original Bentall (87.8/81.2/73.7%). Graft-related events were rare.
Conclusions:
- The neo-modified Cabrol technique is a safe and effective option for managing type A aortic dissection with aortic root involvement.
- This approach offers favorable perioperative and mid-term results, supporting its use in complex aortic dissections.
