Aortic arch pathologies, including aneurysms, dissections, and traumatic injuries, present challenges for open surgical repair due to the complexity of the anatomy and high morbidity. Thoracic endovascular aortic repair (TEVAR) has emerged as a transformative alternative, offering less invasive options, better outcomes, reduced recovery times, and fewer complications. However, maintaining branch vessel perfusion while securing landing zones can be complex. Advanced techniques such as parallel grafts, fenestrated grafts, and branched devices are essential tools for addressing these challenges.
Parallel grafts (chimney, snorkel, periscope) extend sealing zones while preserving branch vessel patency. Fenestrated grafts, particularly with laser fenestration, offer tailored solutions for individual anatomy, and branched devices like the Gore TAG Thoracic Branch Endoprosthesis and Nexus Triomphe provide specialized technology for aortic arch interventions.
Clinical Findings/Procedure Details:
Advanced endovascular techniques, including parallel grafts, fenestrated grafts, and branched devices, have revolutionized aortic arch repair. These minimally invasive methods preserve branch vessel perfusion and are essential for patients unsuitable for open surgery. Case examples offer practical insights into real-world applications, helping interventional radiologists refine their approaches. The continued advancement of device technology will expand possibilities for treating complex aortic arch pathologies.
