Combined Axillary-Femoral Artery Cannulation Versus Conventional Femoral Artery Single Cannulation: Cerebral Protection Benefits in Stanford Type A Aortic Dissection Repair Surgery

Compared with conventional femoral artery single cannulation, combined axillary-femoral artery cannulation provides superior and independent cerebral protection during STAAD surgery. This approach reduces permanent and transient neurological deficits, mitigates early brain injury, enhances neurological and cognitive recovery, and lowers the incidence of postoperative limb ischemia. It holds promise as a safe and effective cerebral protective perfusion strategy in STAAD surgical management.
