Introduction to Aortic Dissection and the Need for Improved Surgical Techniques

• Background: Li Jing discusses the severity of Type A aortic dissection and its high early mortality rate, underscoring the need for improved surgical techniques.

• Mortality Rates: Without treatment, the mortality rate for acute Type A aortic dissection can increase by 1-2% every hour within the first 24-48 hours.

XJ-Procedure: Technical Details

• Innovative Approach: The XJ-Procedure involves using an artificial graft reinforcement at the aortic root to enhance the stability of the anastomosis site.

• Surgical Steps: Li describes how the “skirt” of the artificial graft is internally positioned at the reinforced aortic root and how interrupted mattress sutures with pledgets are used to minimize the risk of tearing, which can occur with continuous suturing.

Clinical Outcomes and Case Analysis

• Effectiveness: Through specific case studies, Li demonstrates the XJ-Procedure’s effectiveness in reducing intraoperative bleeding, shortening recovery times, and improving long-term survival rates.

• Case Presentations: Detailed pre- and post-operative comparisons highlight the significant benefits of this technique.

Surgical Innovations and Future Outlook

• Innovative Features: Li summarizes the innovative aspects of the XJ-Procedure, detailing how it achieves a safer and more effective treatment for aortic dissection.

• Future Prospects: The potential for further technological improvements and broader clinical applications is discussed, aiming for widespread adoption in cardiovascular surgery.
