title: Results of the endovascular abdominal aortic aneurysm repair using the Anaconda aortic endograft.
abstract: OBJECTIVE
  The objective of this study was to evaluate early and late results of the Anaconda aortic endograft (Vascutek, Terumo, Inchinnan, Scotland) in a single-center experience.
  
  
  METHODS
  From September 2005 to March 2012, patients underwent endovascular aortic repair for abdominal aortic aneurysm (AAA) with Anaconda endograft were prospectively enrolled in a dedicated database. Demographic and aortoiliac morphological data were considered. Preoperative planning was based on thoracoabdominal and pelvic computed tomography angiography. Follow-up included duplex ultrasound or computed tomography angiography at 1, 6, and 12 months and yearly thereafter. Primary end points were technical success, early and late primary and primary assisted clinical success (CS), overall and AAA-related survival and freedom from reinterventions. Secondary end points were endoleaks (ELs), steno-obstructive iliac leg complications, and AAA shrinkage.
  
  
  RESULTS
  An Anaconda endograft was implanted in 177 patients (male 94%; mean age, 73.3 ± 7.4 years; American Society of Anesthesiologists class III-IV, 85% and 9%, respectively). The mean AAA diameter, neck length, and diameter were 55 ± 9.7 mm, 26.7 ± 10 mm, and 23 ± 2.3 mm, respectively. There was an aortic neck angle >60° in 44 (25%) patients. Iliac angles >90° were observed in 152 (43%) iliac axes. Technical success was 98.9%. Early CS was 96%. Mean follow-up was 33 ± 23.3 months. Late assisted CS was 97.7%. Survival at 12, 24, and 36 months was 96.4%, 89%, and 86.2%, respectively. There was only one case of late AAA-related mortality. Freedom from reintervention was 94%, 92%, and 85% at 12, 24, and 36 months, respectively. Three (1.7%) conversions occurred during follow-up. There were 14.1% ELs at the completion angiography (EL Ia, 1.1%; EL II, 13%). Late ELs were 20.2% (EL Ia, 1.1%; EL Ib, 2.2%; EL II, 16.9%). Iliac leg complications occurred in 5.6% of the cases. An AAA shrinkage >5 mm was observed in 130 (73.4%) patients. In 7 (4%) cases there was an AAA enlargement >5 mm.
  
  
  CONCLUSIONS
  Data in our series demonstrate that the Anaconda endograft has good early and late results in the treatment of AAAs.
