Key result
Left axillary cannulation was successfully used for cardiopulmonary bypass in a patient with acute type A aortic dissection involving the right axillary and both femoral arteries, leading to uneventful recovery.
Why the study?
Selecting an arterial cannulation site for type A aortic dissection is extremely difficult when dissection involves the right axillary and both femoral arteries.

Left axillary cannulation is a safe and feasible alternative for cardiopulmonary bypass in acute type A aortic dissection when standard cannulation sites are compromised.
May support left axillary cannulation when standard sites are unavailable; hypothesis-generating and requires validation in larger cohorts.
The most commonly used arterial cannulation sites for type A aortic dissection are right axillary artery, femoral artery and both. Direct central aortic cannulation has also been reported. In rare cases, it is extremely difficult to choose an arterial cannulation site for type A aortic dissection due to involvement of the right axillary and both femoral arteries. Herein, we present a 39-year-old male with acute type A aortic dissection with involvement of the right axillary and both femoral arteries. Left axillary cannulation was made and selective cerebral perfusion was performed through direct left common carotid artery cannulation during circulatory arrest. Surgery was performed to replace the ascending aorta and total arch combined with a frozen elephant trunk implantation. The patient recovered uneventfully. To our knowledge, this is a rare case of total aortic arch replacement with frozen elephant trunk implantation through left axillary arterial cannulation for type A aortic dissection in the literature. Left axillary cannulation is a safe and useful choice for type A aortic dissection surgery when right axillary and femoral cannulation are not safe and reliable.

Sun et al. (2022) conducted a case report in Acute type A aortic dissection (n=1). Left axillary cannulation was evaluated on Surgical success and patient recovery. Left axillary cannulation was successfully used for cardiopulmonary bypass in a patient with acute type A aortic dissection involving the right axillary and both femoral arteries, leading to uneventful recovery.
