Quick Yielding Modified Short-Distance Fenestration Technique for the Treatment of Complex Aortic Arch Diseases: a Multicenter Single-Arm Objective Performance Criteria Trial(QYM-Tech Study)

"The intervention in this study involves the application of the Quick Yielding Modified (QYM) technique for the treatment of complex aortic arch diseases. This procedure consists of two main components:~1. Thoracic Endovascular Aortic Repair (TEVAR): This minimally invasive procedure utilizes a covered stent graft to exclude the diseased segment of the thoracic aorta, providing immediate protection against rupture and controlling blood flow.~2. In Situ Fenestration and Revascularization of Supra-Aortic Branches: Following TEVAR, the QYM technique includes creating fenestrations in the stent graft to allow for the revascularization of the supra-aortic branches (such as the brachiocephalic, left common carotid, and left subclavian arteries). This is achieved through direct puncture and reconstruction of the branch vessels, ensuring adequate blood flow to these critical arteries while preserving their function.~The combination of these techniques aims to achieve effective treatment out"
