1 | INTRODUCTION
Diffuse aortic dissection or medial degenerative disease involving the entire aortic arch can lead to the formation of exceptionally large aneurysms[1]. Coarctation of the aorta affects individuals across all age groups and presents with a range of clinical symptoms, either in isolation or in conjunction with other cardiac defects[2]. The combination of an AAA and coarctation of the aorta is a uncommon and serious cardiac malformation, often associated with critical complications such as sepsis, dissection, and aneurysm rupture. Without surgical intervention, patients with coarctation of the aorta face a serious prognosis, with an average life expectancy of only 34 years and a mortality rate of 75% by the age of 43 [3]. Currently, there is a lack of extensive reports and no established consensus on managing this severe condition. In this report, we describe the management of a 45-year-old man with coarctation of the aorta and a significant aortic arch aneurysm.
