Aim. The aim of this paper was to evaluate the midterm outcomes in 90 cases of infrarenal abdominal aortic aneurysm (AAA) treated with Anaconda™ endograft.
Methods. Preoperative, procedural and follow-up data of patients treated with Anaconda™ endograft between September 2005 and February 2008 were prospectively recorded. Severe proximal neck and iliac arteries angulation were not exclusion criteria. Main endpoints were survival, technical and clinical success. Univariate and multivariate Cox proportional hazards analyses were calculated in relation to proximal neck angulation and iliac arteries angulation.
Results. Ninety patients, with a mean age of 73.6±7.1 years, were considered suitable for treatment with Anaconda™ endograft. Mean aneurysm size was 55.6±10.8 mm. A severe angulation of the aortic neck (≥60°) was present in 19 cases (21.1%). The iliac arteries were severely angulated (≥90°) in 16 cases (17.8%). The mean follow-up was 18.1±9.6 months (range 1.1-30.2). Primary technical success was achieved in 100% of the patients. At 24 months follow-up survival, primary and assisted clinical success were respectively 86%, 78.5% and 92.7%. Angulation of the proximal neck and of the iliac arteries was not correlated with survival or technical and clinical success at univariate and multivariate analysis.
Conclusion. The data of this series demonstrate that Anaconda™ endograft has good midterm results in the treatment of infrarenal AAA. The presence of tortuose anatomy did not affect the outcome.
