Effect of endovascular aneurysm repair in treatment of aortic pseudoaneurysms / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the effect of endovascular aneurysm repair (EVAR) in treatment of aortic pseudoaneurysms (AP). Methods: Date of 11 AP patients treated with EVAR were retrospectively reviewed, and the treatment effect and follow-up were analyzed. Results: Single breach of AP was found in all 11 patients, and the technical successful rate of EVAR was 100%. No complication such as endoleakage, bleeding, ischemia of important organs nor perioperative death occurred. The follow-up period was 2 to 24 months. During the follow-up period, 3 patients died and 1 was lost to follow-up. Two patients with infectious AP and 1 Behcet syndrome patient complicated with abdominal AP died of bleeding due to recurrent rupture of the aneurysm 2 months after operation. AP recurred 1 year after operation in 1 patient with Behcet syndrome, and another stent graft was implanted in the left common iliac artery. The stent grafts were unobstructed in the remaining 6 patients without displacement and endoleakage, and no thrombosis was found in the aneurysm. Conclusion: EVAR is an effective and safe method for treatment of AP, and the prognosis is related to the etiology of AP.
