Abstract:
Objective:To analyze the risk factors and prognosis of endoleak after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm.Methods:The clinical data of patients with infrarenal abdominal aortic aneurysms treated by endovascular repair at the Department of Vascular Surgery,the First Affiliated Hospital of Guangxi Medical University from Jun 2012 to Nov 2021 were retrospectively analyzed.Results:During the first follow-up CTA after surgery,136 out of 299 patients had endoleak.A total of 186 patients had at least one CTA reexamination after discharge. Statistical analysis showed that excessive neck angulation was an independent risk factor for type Ⅰa endoleak ( t=-6.108, P<0.001), wider common iliac artery diameter (left Z=-2.787, P=0.005, Right Z=-2.381, P=0.017) and iliac aneurysm ( χ2=6.398, P=0.011) were risk factors for type Ⅰb endoleak. The survival time of patients in endoleak group was similar to no endoleak group. Conclusions:Excessive neck angulation is an independent risk factor for type Ⅰa endoleak. Most leaks resolve spontaneously ,the prognosis is fair.
