title: Long-term results of endovascular treatment for splenic artery aneurysms.
abstract: OBJECTIVE
  The aim of this paper was to evaluate our single-center experience of the management of splenic artery aneurysm (SAA), with particular attention to the long-term results of endovascular treatment.
  
  
  METHODS
  Thirty-eight patients with the diagnosis of SAA at the Tokyo University Hospital during the past 23 years were retrospectively reviewed. Interventions were considered for patients with SAA>2 cm in diameter. Nine patients were treated by transcatheter embolization (TE), and 8 by open surgical repair (SR). Twenty-one patients were observed (OB). TE was performed with microcoils placed distal and proximal to the aneurysm in the afferent artery to isolate the aneurysm.
  
  
  RESULTS
  In the TE group, the primary technical success rate was 100%. No 30-day mortality or any catheter-related complication was observed. The median length of hospital stay after TE, excluding one patient who required further surgery, was shorter than that after SR (8 versus 16 days, P=0.001). During follow-up (median =45 months), no patient died and no recurrence of SAA was observed. In the SR group, all aneurysms were repaired successfully without any severe complication, and no aneurysm-related death occurred during follow-up (median =57 months). In the OB group, no aneurysm rupture or increase in aneurysm size was observed during follow-up (median =35 months).
  
  
  CONCLUSIONS
  TE provided good early and long-term results, comparable to those obtained with conventional SR. In addition, TE had several advantages associated with its minimal invasiveness. TE by the isolation technique could be the first-line strategy for all SAA requiring treatment.
