Hypothermic Circulatory Arrest (HCA) In Adult Aortic Arch Surgery: A Review of HCA and its Anesthetic Implications

Diseases affecting the aortic arch often require surgical intervention. Hypothermic circulatory arrest (HCA) enables a safe approach during open aortic arch surgeries. Additionally, HCA provides neuroprotection by reducing cerebral metabolism and oxygen requirements. However, HCA comes with significant risk (e.g. neurologic dysfunction, stroke, and coagulopathy), and it is important for the cardiac anesthesiologist to have a complete understanding of the surgical techniques, possible complications, and management strategies.
