Conditions:

Complex Abdominal Aortic Aneurysm, ie. Juxtarenal or Suprarenal Aortic Aneurysms, Treated by Fenestrated Endovascular Aortic Aneurysm Repair or Open Repair

Eligibility:

Brief Summary

Introduction: Complex abdominal aortic aneurysms (CAA) are defined as abdominal aneurysms that are anatomically unsuitable for a standard endovascular repair because of a short infrarenal neck or no i...

Eligibility Criteria

Inclusion

  • Presence of an abdominal aortic aneurysm greater than 50 mm in diameter, anatomically unsuitable for a standard infrarenal stent graft because of an inadequate infrarenal neck and for which a treatment by FEVAR or OR is considered. The AAA can be identified as follows, according to preoperative imaging:
  • Short-neck or juxtarenal aneurysm: if treated by OR, would require an infrarenal proximal aortic suture, regardless of the level of clamping.
  • Suprarenal aneurysm: if treated by OR, would require a suprarenal/supramesenteric/ supraceliac aortic cross clamping, and a proximal bevelled suture and/or a separate revascularization of at least one renal artery.
  • Type IV thoracoabdominal aneurysm: aneurysm extending up to the level of the diaphragm pillars, requiring a supracoeliac clamping with a proximal bevelled suture and/or separate revascularization of at least one renal artery if treated by open surgery.
  • Patients aged 18 and over
  • Patient who expressed a non-opposition to participating in the study.
  • Patient affiliated to the French healyh care system

Exclusion

  • Presence of a type I, II, III or V thoracoabdominal aneurysm according to the modified Crawford Classification.
  • Patients for whom an alternative surgical technique is being considered and listes below: laparoscopic aortic repair, hybrid repair, CHIMPS, surgeon modified stent grafting, in situ fenestrations.
  • Patients deemed at prohibitive risk for OR :
  • uncompensated cardiac failure with LVEF \<40% (NYHA class III and IV)
  • Coronary revascularization \< 1 month
  • Large myocardial ischemia \>3 segments not revascularized or not revascularizable
  • Non-revascularized or non-revascularizable unstable angina
  • Non-operable tight aortic stenosis (mean gradient \> 40 mmHg, valve area \< 1 cm2, peak transvalvular velocity \> 4 m/s)
  • Non operable significant mitral shrinkage (area \<1.5cm²)
  • FEV1 \< 50% of the theoretical value
  • Home oxygen therapy
  • Chronic renal failure with clearance \< 30 ml/min
  • presence of a main renal artery less than 4 mm in diameter
  • Special anatomical configurations: horseshoe kidney, pelvic kidney.
  • Lesions of "shaggy" aorta at the visceral segment or at the lower thoracic aorta
  • History of abdominal aortic surgery (open or endovascular)
  • Dissecting, infected, ruptured or painful aneurysm
  • Life expectancy less than 2 years
  • Person under judicial protection
  • Person under tutorship or curatorship
  • Pregnant or breastfeeding woman
