Microsurgical one-stage treatment of intracranial mirror aneurysms via bilateral frontolateral approaches

<p><strong>Objective </strong> To investigate surgical strategies, clinical effects and complications of microsurgical one-stage treatment of intracranial mirror aneurysms via bilateral frontolateral approaches. <strong>Methods </strong> Review clinical data of 18 cases with anterior circulation mirror aneurysms who underwent one-stage clipping via bilateral frontolateral approaches from July 2010 to July 2015 admitted to Department of Neurosurgery in Tianjin Huanhu Hospital. The operative efficacy was evaluated according to postoperative Glasgow Outcome Scale (GOS). <strong>Results</strong> The 36 aneurysms in 18 patients were successfully clipped via bilateral frontolateral approaches at one-stage, including 18 posterior communicating artery (PCoA) mirror aneurysms in 9 cases and 18 middle cerebral artery (MCA) mirror aneurysms in 9 cases. GOS score of 5 was discovered in 16 cases, and 4 was discovered in 2 cases after operation. One case underwent ventriculoperitoneal shunting (VPS) due to communicating hydrocephalus, one case got postoperative pulmonary infection and no death occurred. Intracranial CTA at 6 months postoperatively showed aneurysms of 18 patients were clipped completely, the parent artery blood flow was smooth, and no recurrence was found. <strong>Conclusions</strong> Microsurgical one-stage clipping via bilateral frontolateral approaches for treating intracranial mirror aneurysms is a sugrical method with small incision, fitting surgical field, high safety, satisfactory effect and good prognosis, which is a new minimally invasive neurosurgical technique.</p><p> </p><p><strong>DOI: </strong>10.3969/j.issn.1672-6731.2016.08.012
