Experience with the Ankura Thoracic Stent Graft and In-situ Fenestration for the Left Subclavian Artery with the Fu-Through Needle - a Technical Overview and Comparison to Similar Endovascular Techniques.

Thoracic endovascular aortic repair (TEVAR) is a widespread minimally invasive procedure prevalently used to treat thoracic aortic pathologies. However, when the left subclavian artery (LSA) is involved in the pathology, a more complex surgical approach is required to guarantee the perfusion of the vertebral and brachial arteries. In fact, coverage of the LSA has been proven to be associated with a higher risk of stroke, spinal cord ischemia, and arm ischemia.
