Abstract:
Objective:To examine the outcome of endovascular treatment in patients of isolated abdominal aortic dissection.Methods:From February 2012 to June 2020, 61 patients (44 males, 17 females) with an age of (60.2±11.4) years (range: 43 to 87 years) of isolated abdominal aortic dissection who underwent the endovascular treatment, including bifurcated and straight aortic stent graft, in the Department of Vascular Surgery, the Second Xiangya Hospital, Central South University were enrolled. There were 47 patients treated with bifurcated aortic stent grafts and 14 patients with straight aortic stent grafts. Patient demographic, preoperative, intraoperative, perioperative data were collected. Clinical follow-up data, including mortality, relative complications and aortic remodeling, were obtained. Kaplan-Meier method and Log-rank test was used to calculate and compare the rates of survival and freedom from all adverse events.Results:The operative time was (142.4±47.9) minutes (range:70 to 310 minutes) and (95.7±23.7) minutes (range: 70 to 150 minutes) in bifurcated stent group and straight stent group, respectively. The perioperative mortality was 0. One patient had partial occlusion of the left renal artery, and 3 patients had type Ⅰa endoleak post-operation. The follow-up period was (37.1±22.1) months (range: 3 to 91 months). Three patents suffered from type B aortic dissection; one of them progressed into type A aortic dissection and died, another one was treated with secondary endovascular operation, and the remaining one was treated conservatively. One patient had type A aortic dissection and was treated conservatively for 57 months without any discomfort. Stent grafts in iliac artery occlusion happened in 2 patients treated with a bifurcated graft, one of them was treated with a secondary operation because of severe symptom. Aortic remodeling was well with the treatment of bifurcated and straight grafts. There was no difference in the cumulative survival ( P=0.584) and freedom from all adverse events ( P=0.309) between the two different endovascular treatment strategies. Conclusion:Endovascular aortic repair is an effective and safe treatment strategy for isolated abdominal aortic dissection with reliable mid-term result and excellent aortic remodeling.
