title: Long-term results of surgical treatment of aneurysms of digestive arteries.
abstract: BACKGROUND
  The aim of this study was to document the long-term results of open surgical treatment of aneurysms of the digestive arteries.
  
  
  METHODS
  Between January 2000 and March 2010, 60 patients were operated on for 78 aneurysms of the digestive arteries at our institution. The mean age of patients was 61 years (31-84 years). The average lesion diameter was 33 mm (range 10-90 mm). Topographic distribution involved the coeliac trunk in 23 cases (30%), hepatic artery in 20 (26%), splenic artery in 19 (24%), superior mesenteric artery in 11 (14%), gastroduodenal artery in 3 (4%), and pancreaticoduodenal arteries in 2 (3%). Twenty patients (33%) were symptomatic, 1 of whom presented with aneurysmal rupture (1.7%). Follow-up was prospective and an actuarial analysis was carried out. Only 3 patients (5%) were lost to follow-up.
  
  
  RESULTS
  Hospital mortality was 1.7% (upper gastrointestinal bleeding from gastric metastases of a kidney cancer). Postoperative complications were mainly respiratory (18%), digestive (18%), and renal (13%). Five reintervention procedures (8%) were necessary: 2 for colonic ischemia; 1 for intestinal bleeding; 1 for secondary graft infection due to peritonitis; and 1 for drainage of an acute pancreatitis. The average follow-up was 42 months (range 1-120 months). The actuarial survival rates were 98% at 1 month and 1 year, and 97% at 5 and 10 years, respectively. One late death occurred at 22 months (bronchopulmonary cancer). Three late reinterventions were carried out: 2 re-establishments of digestive continuity and 1 embolization for a recurrent aneurysm 7 years after the initial operation. The primary patency rate of the revascularizations was 98% at 1 month and 1 year, and 95% at 5 and 10 years. The rates of indemnity of restenosis or thrombosis were 98% at 1 month and 1 year, and 95% and 93% to 5 and 10 years, respectively. The rates of freedom of reintervention on bypasses were 98% at 1 month and 1 and 5 years, and 97% at 10 years.
  
  
  CONCLUSIONS
  Open surgical treatment of aneurysms of the digestive arteries offers excellent long-term results in terms of patency. It is with these late results that endovascular techniques will have to be compared to define the best therapeutic strategy.
