Abstract
Objective To investigate the microsurgical strategy and efficacy of paraclinoid aneurysms. Methods The clinical data of 20 patients with paraclinoid aneurysms were retrospectively reviewed who underwent microsurgical clipping from November 2015 to March 2017 at Neurosurgery Department of the First Affiliated Hospital of Chongqing Medical University. The operative methods included simple clipping and clipping of aneurismal neck and parent artery reconstruction. After the operation, the aneurysm clipping was examined by CTA or DSA, and the Glasgow prognosis score (GOS) was used to evaluate the clinical effect. All patients were followed up by outpatient clinic or telephone, and the GOS scale was used to assess the patient's prognosis. Results All patients achieved satisfactory results. There was no aneurysm recurrence or rebleeding in this series detected by CTA or DSA. Only 1 case of unruptured aneurysm had a small residual neck after treatment. There was no death during the perioperative period. The GOS grade was Ⅴ in 13 cases, Ⅳ in 6 and Ⅲ in 1 at discharge. All patients were followed up for a period of 1-18 months, with an average of 10±6 months. The GOS grade was Ⅴ in 16 cases and Ⅳ in 4 cases. Conclusion Microsurgical clipping of paraclinoid aneurysm seems to be safe and feasible, which could have a favorable outcome. Key words: Intracranial aneurysm; Microsurgery; Treatment outcome
