title: Juxtarenal aortic aneurysm with hostile neck anatomy: midterm results of minilaparotomy versus f-EVAR.
abstract: OBJECTIVE
  The aim of this study was to compare the results of complex aneurysm (hostile neck anatomies) repair in high-risk patients with two minimally invasive techniques, fenestrated endografting (f-EVAR where EVAR stands for endovascular aneurysm repair) and minilaparotomy.
  
  
  METHODS
  All high-risk patients (N.=50, group 1) with hostile neck abdominal aortic aneurysms (AAAs) operated in the vascular surgery department of the "Policlinico Universitario G. Martino" of Messina (Italy) during a 5-year period (January 2006-December 2010) were cross-matched with 50 similar patients (group 2) treated in the Vascular Surgery Department of the "Hopital Cardiologique" University of Lille (France) with similar anatomies, comorbidities and risk factors. The patients in group 1 underwent open minilaparotomy surgery, and the patients in group 2 were treated with f-EVAR. The aim of our study was to compare perioperative complications, survival and reintervention rates.
  
  
  RESULTS
  Perioperative cardiac complications occurred in 5 patients (10%) in group 1, and 1 patient (2%) in group 2 (P<0.092). Renal impairment not requiring permanent hemodialysis was significantly higher in group 1 (14% vs. 2% P<0.027), as well as respiratory complications (32% vs. 2% P<0.0001). Five patients (10%) in group 1 underwent reintervention vs. 4 patients in group 2 (P<0.7268). There was no statistically significant difference for survival rates at 30 days (92% in group 1 and 96% in group 2; P=0.399); at six months (90% vs. 96%; P=0.239); at one year (90% vs. 96%; P=0.239); and at two years (84% vs. 94%; P=0.110). However, we observed statistically significant differences in survival rates at three years (74% vs. 94%; P<0.006); at four years (70% vs. 86%; P<0.005); and at five years (65% vs. 68%; P<0.003).
  
  
  CONCLUSIONS
  Our results showed that both techniques are effective in the treatment of AAA with hostile neck in high-risk patients. Although operative mortality rate was not statistically different, f-EVAR showed better results in terms of early complications and late survival.
