Analysis of Clinical Outcome and Complications After Microsurgical Clipping of Unruptured Paraclinoid Aneurysms / 대한뇌혈관외과학회지

ABSTRACT

OBJECTIVE: The study reports the clinical outcomes and complication rates of microsurgical clipping of unruptured paraclinoid aneurysms. METHODS: From July 1997 to December 2008, 61 patients underwent microsurgical clipping for 61 unruptured paraclinoid aneurysms in our institute. Entire medical records, radiographic data, and operation records were reviewed retrospectively. RESULTS: After the microsurgical clipping, complete obstruction was achieved in 56 patients (91.8%). Visual disturbance (nine cases, 14.8%) was the most frequent complication. Overall, 59 patients (96.7%) had a good long-term outcome (Glasgow outcome scale score of 4-5 3 months post-operatively). CONCLUSION: For patients with paraclinoid aneurysms, satisfactory outcomes can be achieved by microneurosurgical management. These results will be useful when considering treatment of an unruptured paraclinoid aneurysm.
