Insights
This study introduces a novel transaxillary technique for cannulating all supra-aortic vessels during triple-branch arch repair. The method uses minimal access points, reducing complications and potentially changing vascular access standards.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Medical Device Technology
Background:
- Triple-branch arch repair is a complex procedure requiring access to multiple supra-aortic vessels.
- Current techniques may involve multiple access sites and manipulation of carotid arteries, increasing complication risks.
Purpose of the Study:
- To describe the transaxillary branch-to-branch-to-branch carotid catheterization technique (3BRA-CCE IT).
- To demonstrate its utility for cannulating all supra-aortic vessels during triple-branch arch repair using limited access.
Main Methods:
- The transaxillary 3BRA-CCE IT utilizes one femoral and one axillary artery access.
- It involves sequential catheterization and bridging of the innominate artery, left subclavian artery, and left common carotid artery branches.
- A unique guidewire technique creates a "branch-to-branch-to-branch" pathway for sheath advancement.
Main Results:
- The technique was successfully applied in a series of 5 patients undergoing triple-branch arch repair.
- Catheterization of all supra-aortic vessels was achieved without direct manipulation of the carotid arteries.
- The procedure was performed using only two vascular access points: femoral and right axillary artery.
Conclusions:
- The transaxillary 3BRA-CCE IT enables comprehensive supra-aortic vessel access in triple-branch arch repair.
- This approach avoids carotid artery manipulation, reducing risks of bleeding, reintervention, cranial nerve injury, and operative time.
- The technique offers a potential new standard for vascular access in these procedures.
Purpose:
To describe the transaxillary branch-to-branch-to-branch carotid catheterization technique (tranaxillary 3BRA-CCE IT) for cannulation of all supra-aortic vessels using only 1 femoral and 1 axillary access during triple-branch arch repair.
Technique:
After deployment of the triple-branch arch device, catheterization and bridging of the innominate artery (IA) should be performed through a right axillary access (cutdown or percutaneous). Then, the retrograde left subclavian (LSA) branch should be catheterized (if not preloaded) from a percutaneous femoral access, and a 12×90Fr sheath should be advanced to the outside of the endograft. Subsequently, catheterization of the left common carotid artery (LCCA) antegrade branch should be performed, followed by snaring of a wire in the ascending aorta which was inserted through the axillary access, creating a branch-to-branch-to-branch through-and-through guidewire. Over the axillary access, a 12×45Fr sheath should be inserted into the IA branch and looped in the ascending aorta using a push-and-pull technique so that it faces the LCCA branch, allowing for stable catheterization of the LCCA. The retrograde LSA branch should then be bridged following the standard fashion.
Conclusions:
This series of 5 patients demonstrates that triple-branch arch repair can be performed with the transaxillary 3BRA-CCE IT, allowing catheterization of the supra-aortic vessels without manipulation of the carotid arteries.
Clinical Impact:
The transaxillary 3BRA-CCE IT allows catheterization and bridging of all supra-aortic vessels in triple-branch arch repair through only 2 vascular access points, the femoral artery and the right axillary artery. This technique avoids carotid surgical cutdown and manipulation during these procedures, reducing the risk of access site complications, including bleeding and reintervention, reintubation, cranial nerve lesions, increased operating time, and so on, and has the potential to change the current vascular access standard used during triple-branch arch repair.
