Association Between Bovine Aortic Arch Anatomy and Stroke After Thoracic Endovascular Aortic Repair

BAA was correlated with an increased risk of early and overall stroke following TEVAR, particularly among older and type A BAA patients.Clinical ImpactIndividualized stroke prevention protocols and efficient neuroprotective measures should be developed for patients with BAA and adequate anticoagulation should be ensured to reduce the risk of embolism during TEVAR. This population should also ensure proper needle alignment. For instance, minimize the contact between the guide wire and the aortic arch wall. Temporal-occlusion of the carotid dynamic pulse during stent release might prevent solid fragments from entering into the craniocerebral artery. Additionally, thorough CO₂ or saline flushing technique can be utilized for all the stentgrafts. Furthermore, distal cerebral embolic protection devices should be conducted in patients with a BAA during TEVAR.
