Multibranched Frozen Elephant Trunk with Left Subclavian Artery Cannulation.

Patients with aortic pathology involving the ascending aorta, the arch, and the descending aorta present a complex surgical challenge. A one-step hybrid procedure with ascending aorta repair, arch debranching, and frozen elephant trunk is reported in five patients. Left subclavian artery side graft cannulation is used to perfuse the spinal cord during circulatory arrest time.
