title: [Only overlapping stents therapy for intracranial vertebral artery dissection aneurysms].
abstract: OBJECTIVE
  To evaluate the feasibility, safety, clinical, and angiographic follow-up of only overlapping stents therapy for intracranial vertebral artery dissection aneurysms (VADA).
  
  
  METHODS
  Eight consecutive patients (6 men, 2 women; mean age 46.8 years ranging from 34 to 62 years) with intracranial VADA admitted to Department of Neurology, Chinese People's Liberation Army General Hospital from June 2008 to June 2014 were retrospectively reviewed. All patients were diagnosed intracranial VADA by MRI or digital subtraction angiography (DSA). All patients were treated by only overlapping stents therapy under general anesthesia. In the endovascular treatment process 2 to 3 Solitaire, Neuroform or Wingspan self-expandable stents were overlapping implanted in the segment of the aneurysms. All patients received routine antiplatelet therapy before and after endovascular treatment.
  
  
  RESULTS
  The operative procedures were succeeded in all patients. Eight patients were implanted 18 stents (2 patients, 3 stents; 6 patients, 2 stents). The stents were located accurately and implanted smoothly, none perioperative complications occurred. All patients lived and worked normally and had no recurrent symptoms on follow-up of 6 to 48 months. All patients performed DSA reexamination on follow-up. The aneurysm blocked in 2 patients, the size lessened in 2 patients, and the size had no change in 3 patients.
  
  
  CONCLUSIONS
  Only overlapping stents therapy for treating intracranial VADA is feasible and has good operation safety. Preliminary follow-up results show that it can reduce the probability of thrombosis or hemorrhage and can improve the patients' life quality.
