Giant Ascending Aorta Aneurysm (AAA) is a rare condition, because of early diagnosis incidence appears to be increasing as a result of routine screening, increased clinical awareness, and improved imaging modalities. The etiology of aneurysms involving the aortic root and ascending aorta can be genetically triggered, degenerative or atherosclerotic, inflammatory, or can result from infectious diseases. According to many studies for ascending aortic aneurysms larger than 6 cm the risk of rupture, dissection, or deaths was 15.6, making it a large life-threatening aneurysm.
We present the case of a Giant AAA of about 8,7 cm diameter in a 68 years old man who was successfully operated on for ascending aorta and aortic root replacement under modified Bentall technique using composite mechanical conduit with coronary reimplantation.
Conclusion; Ascending giant aortic aneurysm is a rare finding, varying from asymptomatic clinical presentation. Surgical treatment remains the standard treatment with very good results. The selection of the operating technique is very individual, depending on the case and the experience of the surgeon.
