Embolization of cerebral aneurysms. A new therapeutic possibility]

Treatment of cerebral aneurysms with Guglielmi Detachable Coils (GDC) was performed for the first time in Scandinavia in 1992. The experience at Ullevål University Clinic from 1994 to 1996 comprises 27 surgically inoperable aneurysms. Successful embolization was performed in 20 patients. No complications were seen during the procedure. However, renewed bleeding with fatal outcome occurred in one patient. In accordance with other colleagues we consider this treatment to be unsuitable for wide neck aneurysms (> 5 mm). For this reason seven patients were not treated. We conclude that GDC embolization seems to be an effective therapy for selected inoperable aneurysms. In the near future the method will probably be used to treat some of the surgically operable aneurysms as well.
