Endovascular aortic arch repair under monitored anaesthesia care: maximizing microinvasiveness

Abstract

Patients with aortic arch pathologies after surgery for type-A acute aortic dissection represent a challenging population since open surgery is associated with a non-negligible rate of mortality and complications. Microinvasive endovascular aortic arch repair Arch-Thoracic EndoVascular Aortic Repair (Ar-TEVAR) has shown promising results in high-risk patients. Ar-TEVAR is usually performed under general anaesthesia. We report the case of an 83-year-old man with a history of ascending aorta replacement for type-A acute aortic dissection who was referred for an anastomotic pseudoaneurysm. Ar-TEVAR using an off-the-shelf single-branch aortic arch stent graft was chosen. In order to further minimize procedural invasiveness, monitored anaesthesia care (local anaesthesia with sedation and analgesia) was performed since it provides less stress on the cardiovascular and respiratory systems and overall leads to a faster recovery especially in elderly patients.
