COMPLICATIONS OF ENDOVASCULAR TREATMENT O F INTRACRANIAL ANEURYSMS WITH METALLIC MICROCOILS

Embolization of intracranial aneurisms with coils. The authors present the results and complications of microcoils embolization of intracran ial aneurysms in 28 patients. Fibers platinum microcoils were used (Ta rget Therapeutic) 28 patients (males : 6, females : 22; mean age : 51 years) were treated, 27 suffered from sub-arachnoid hemorrhage (SAH) a nd one presented with a pseudotumoral syndrome (giant aneurysm). All p atients were evaluated on the day of treatment, according to the World Federation of Neuro-Surgeon classification (W.F.N.S.) of SAH and afte r 4 months of follow-up. At a mean follow-up period of 4 months, accor ding to Glasgow Outcome Scale (G.O.S.) there were 13 cases of good res ults, 5 cases of ''moderate disability'', 2 cases of ''severe disabili ty'', 2 cases of ''vegetative state'' and 6 deaths. Complications were observed in 11/28 cases. Coils migration and malposition in the paren t artery were linked to the procedure (mechanical detachable coil) and resulted in severe deficit (one case), transient disability (one case ) or went unnoticed (4 cases). Primary or secondary complete occlusion was achieved in 8/28 patients (32%). A majority of cases (11 cases) e nded with stable residual aneurysmal sac lumen while rebleeding occurr ed in 3 patients and was responsible for 2 deaths. In the third case a favourable outcome was obtained after balloon occlusion of the parent artery.
