title: Angiographic and clinical result of endovascular treatment in paraclinoid aneurysms.
abstract: OBJECTIVE
  The purpose of this study was to analyze the results of an immediate and mid-term angiographic and clinical follow-up of endovascular treatment for paraclinoid aneurysms.
  
  
  METHODS
  From January 2002 to December 2012, a total of 113 consecutive patients (mean age: 56.2 years) with 116 paraclinoid saccular aneurysms (ruptured or unruptured) were treated with endovascular coiling procedures. Clinical and angiographic outcomes were retrospectively evaluated.
  
  
  RESULTS
  Ninety-three patients (82.3%) were female. The mean size of the aneurysm was 5.5 mm, and 101 aneurysms (87.1%) had a wide neck. Immediate catheter angiography showed complete occlusion in 40 aneurysms (34.5%), remnant sac in 51 (43.9%), and remnant neck in 25 (21.6%). Follow-up angiographic studies were performed on 80 aneurysms (69%) at a mean period of 20.4 months. Compared with immediate angiographic results, follow-up angiograms showed no change in 38 aneurysms, improvement in 37 (Fig. 2), and recanalization in 5. There were 6 procedure-related complications (5.2%), with permanent morbidity in one patient.
  
  
  CONCLUSIONS
  Out study suggests that properly selected patients with paraclinoid aneurysms can be successfully treated by endovascular means.
