Endovascular treatment of incidental cerebral aneurysms. report on 115 cases treated with guglielmi detachable coils.

One hundred and fifteen patients with 120 intracranial incidental aneurysms were embolized using the GDC endovascular technique at UCLA Medical Center. Angiographic results showed complete or near complete aneurysm occlusion in 109 aneurysms (91%) and an incomplete occlusion in five aneurysms (4%). An unsuccessful GDC embolization was attempted in six aneurysms (5%). One hundred and nine patients (94.8%) remained neurologically intact or unchanged from initial clinical status. Five patients (4.3%) deteriorated due to immediate procedural complications. All these complications occurred in the first 50 patients. No clinical complications were observed in the last 65 patients .. In Groups 1 and 3, the average length of hospitalization was 3.3 days. The technical evolution of the GDC technology has proved to be safe for the treatment of incidental aneurysms (0% morbidity in the last 65 patients). The topography of the aneurysm/s and the clinical condition of the patient did not influence final anatomical or clinical outcomes. GDC technology also brings a positive economical impact by decreasing hospitalization time and eliminating postembolization ICU care.
