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

Zentralbl Chir. 2023 Oct;148(5):425-428. doi: 10.1055/a-2166-2860. Epub 2023 Oct 16.ABSTRACTThoracic 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.Historically, carotid-subclavian bypass or subclavian transposition has been the only treatment options to restore the perfusion of the LSA. For the past 10 years, different endovascular techniques have been implemented in the endovascular armamentarium to reduce the risk of complications related to surgical treatment such as infection, bleeding, and chylothorax.Currently, physician-modified grafts, in situ fenestration, chimneys, and branched or fenestrated devices are available. The aim of this overview is to describe the technique with the Ankura thoracic stent graft and in situ fenestration with the Futhrough needle and thus to shed light on the different approaches by comparing their pros and cons.PMID:37846165 | DOI:10.1055/a-2166-2860
