Multidetector Computed Tomography Angiography in the Follow-up of Surgical Treated Patients with Multiple Intracranial Aneurysms

OBJECTIVE: The purpose of this study was to assess the usefulness of MDCT (multidetector computed tomography) angiography as a routine follow-up examination of surgically treated patients with multiple intracranial aneurysms.METHODS: Thirty seven patients with a total of 92 multiple intracranial aneurysms underwent MDCT angiography to evaluate residual aneurysm remnants and de novo aneurysm formation.The mean period between aneurysm surgery and MDCT angiography examination was 8.9 years.The investigations were assessed by an experienced radiologists and neurosurgeons.RESULTS: Eight patients (21.6%) showed abnormal findings on follow-up MDCT angiography: aneurysm remnants (5.4%) and de novo formed aneurysms (18.9%).Three of them were operated: one for reposition of the placed clips and two were treated by direct clipping of de novo formed aneurysm.Two patients were suitable for endovascular treatment.CONCLUSION: MDCT angiography is an useful routine examination for long-term follow-up of surgically treated patients with multiple intracranial aneurysms.
