Intraoperative Type B Aortic Dissection During Total Arch Replacement

Background: Intraoperative aortic dissection is an extremely serious complication that should be prevented whenever possible. When it does occur, it requires urgent clinical management. Case presentation: We report the case of a 78-year-old man with Marfan syndrome who developed an intraoperative complicated type B aortic dissection with a distal anastomosis entry site during total arch replacement for a chronic dissection. Conclusion: Performing immediate thoracic endovascular aortic repair, we were able to improve malperfusion to the lower extremities that occurred during total arch replacement.
