An Alternative Technique for Hemiarch Replacement Without Using Deep Hypothermic Circulatory Arrest.
We describe an alternate technique to perform a replacement of the aortic hemiarch without the need for hypothermic circulatory arrest by axillary cannulation and arch vessel isolation. In 2015, 3 patients underwent hemiarch reconstructions for ascending aortic aneurysms that extended into the arch. Each was performed using right axillary cannulation, isolation and clamping of the innominate artery with isolation, and tangential clamping of the aorta distal to the innominate. There were no neurologic events and no perioperative morbidity or mortality.
