title: The endovascular management of pericallosal artery aneurysms.
abstract: OBJECTIVE
  to describe our experience with a series of 18 patients with pericallosal artery aneurysms, in whom endovascular coil insertion was attempted.
  
  
  METHODS
  the CT and angiographic appearances, coiling techniques and patient outcomes are discussed.
  
  
  RESULTS
  we encountered a higher than expected level of technical difficulty and procedure related complication than when coiling aneurysms in more common locations. In particular the distal position of the aneurysms lead to poorer control over the microcatheter position. Procedure related rupture occurred in three cases. Coiling was not possible in one case only. An association between an angulated bifurcation of the anterior cerebral artery and a sidewall aneurysm configuration was noted.
  
  
  CONCLUSIONS
  despite the technical difficulties and high procedure related rupture rate, coiling of pericallosal aneurysms is feasible and has good outcome.
