title: Long-term follow-up of intracranial aneurysms treated with endovascular coiling: experience from one institution.
abstract: BACKGROUND
  Our aim was to evaluate the long-term treatment results in patients with intracranial aneurysms treated with endovascular techniques.
  
  
  METHODS
  Forty-four patients treated due to intracranial aneurysms between 1996 and 2002 were investigated with a time-of-flight sequence magnetic resonance angiography (TOF MRA).
  
  
  RESULTS
  Depending on the assessment, 47% to 51% of the treated aneurysms had a residual neck at the last digital subtraction angiography follow-up. There was filling of the aneurysm base (2%) in only 1 patient, whereas the remaining aneurysms were totally occluded. A TOF MRA performed 6 to 14 (mean 9.68) years after the last procedure showed a stable result in 93.9% of the treated aneurysms. There were no de novo aneurysms and previously untreated aneurysms were unchanged in size.
  
  
  CONCLUSIONS
  Our long-term follow-up showed a stable result in previously coiled intracranial aneurysms.
