Patients
Between January 2017 to January 2021, 60 cases of ATAAD patients were operated on with ascending aorta replacement, total arch replacement, and FET. 48 cases patients were divided into two groups, according to FET length. For example, 80mm and 100mm were divided into short FET groups, 120mm and 150mm were divided into long FET groups. The range of aortic dissection involves the celiac artery, or the renal artery, or the bifurcation at the level of the iliac artery. All patients had no history of cardiovascular surgery. CTA scans were performed preoperative and postoperative 1 to 3 months. Preoperative and postoperative analysis and three-dimension reconstruction were performed on each patient.
