Objective
To determine the recanalisation rate of GDC-treated aneurysms, and to reveal determinating factors.
Methods
We could include 89 aneurysms which were treated with GDC in our department and which had a follow-up of at least 18 months. The following criteria which might influence aneurysm recanalisation were evaluated: age, sex, location, rupture, size, neck.
Results
70 % were completely occluded,12 % had a neck remnant and 18% showed signs of recanalisation. Age, sex and localisation did not influence recanalisation. A bigger size, wider neck and rupture increased the risc of recanalisation.
Conclusions
Although recanalisation rate is low, the risk of re-bleeding in incompletely occluded aneurysms is higher than in completely occluded aneurysms. Thus new material, such as, hydrocoils or MATRIX will hopefully reduce the risk of recanalisation.
