Abstract

Japanese guidelines on the diagnosis and treatment of aortic aneurysm and aortic dissection revised in 2020 recommends open surgical treatments for extensive chronic type B dissected aortic aneurysms (Class IIa) if the diameters of the aneurysms are over 60 mm. The current lecture demonstrates the practical surgical procedures including surgical approaches, settings of cardiopulmonary bypass, strategies of protections for spinal cord and visceral vital organs, and its short-term outcomes.
