The Second Tianfu Great Vessel Conference (TFS 2024) was successfully held on May 17-18, 2024, in Chengdu. Standing at the pinnacle of medical excellence, we gaze into the future of the vascular discipline, fully aware of the heavy responsibility and honorable mission we carry. As part of this discipline, we are committed to advancing the field and enhancing diagnostic and treatment levels. In the future, we will decode the TFS lecture content piece by piece to provide you with the latest insights into vascular treatment.
During this conference, Professor Tang Jingdong from Fudan University Affiliated Pudong Hospital shared innovative techniques and applications for treating the three branches of the aortic arch without bypass. This technology not only enhances the safety and efficacy of treatments but also simplifies the surgical process and reduces patient recovery time.
01 Research Background and Current Treatment Status
Treatment options for aortic arch pathologies include hemi-arch replacement with open distal anastomosis, total arch replacement, frozen elephant trunk prosthesis, and thoracic endovascular aortic repair (TEVAR). Complications of thoracic endovascular repair include stroke, spinal ischemia, endoleaks, and stent collapse, with stroke incidence rates ranging from 1.2% to 8.2%.
02 Left Subclavian Artery Reconstruction
Without the use of bypass, reconstruction of the left subclavian artery using chimney and window/branch stent techniques effectively reduces the incidence of post-TEVAR stroke from 5.6%-8.0% to 3.1%-5.3%.
03 Technique for ‘Type I Endoleak’ Induced by Balloon Dilation
Simultaneous balloon dilation and thoracic aortic stent deployment create a gap between the stent and the aortic wall, temporarily forming a Type I endoleak that helps maintain smooth blood flow through the branches of the aortic arch.
04 Intraoperative In Situ Fenestration for Reconstructing Aortic Arch Branches
Intraoperative in situ fenestration allows for precise reconstruction of aortic arch branches without the need for traditional open surgery, ensuring normal blood flow.
05 Postoperative Results and Technological Advantages
This technique is applicable to various types of aortic arch pathologies, boasting a high technical success rate and no early (≤30 days) complications, providing a safer and more effective treatment option.
06 Updated Treatment Guidelines
While the research shows promising early results, it remains retrospective with a small patient sample, lacking mid to long-term follow-up data and a control group.

Update from TFS 2024
Prof. Tang Jingdong from Fudan University presented groundbreaking intraluminal treatments for the aortic arch at #TFS2024, Chengdu.
Innovative Approach:
• No Bypass Needed: Techniques such as chimney and window/branch stent have revolutionized the way we treat the three branches of the aortic arch, enhancing safety and reducing recovery times.
• Reduced Stroke Risk: Post-TEVAR stroke incidence has decreased from up to 8.0% to as low as 3.1% thanks to these innovative methods.
Technical Highlights:
• Type I Endoleak Management: Balloon dilation during stent deployment can temporarily allow a controlled Type I endoleak, ensuring unimpeded blood flow.
• In Situ Fenestration: This technique permits precise, real-time reconstruction of aortic arch branches during surgery.
Successful Outcomes:
Early results indicate high success rates without major complications, promising a significant improvement in treating aortic arch pathologies.
Ongoing Research:
These techniques are under continuous evaluation to confirm long-term benefits and effectiveness.
