Application of multi-technology in intracranial giant aneurysm microsurgery / 中华显微外科杂志

ABSTRACT

ObjectiveTo discuss the application of neurophysiological monitoring (NEPM), intraoperative color Doppler ultrasonography, fluorescein angiography and neuroendoscope in clinical effects of intracranial giant aneurysm microsurgey. MethodsTo retrospectively review the clinical data of 17 intracranial giant aneurysm. Pre-operative imaging were used, including 3D- CTA, MRI and DSA, to make dectection and delineation of the aneurysm.The NEPM to evaluate the nerve function,assess the qualitative and quantitative flow rate of aneurysm and surrounding blood vessels by Doppler ultrasonography and fluorescein angiography,and reveal opography of aneurysm,protect the considerable perf.vessels and nerves by neuroendoscope.Operative techniques were used including parent artery control,aneurysm neck forming,aneurysm decompression and resection,obliteration of aneurysm with multiple clips and vasospasm protection.Results Seventeen cases of giant aneurysms were clipped successfully under muti-technology, follow-up demonstrated excellent neurological outcomes in 15 cases, one case had mild disability, one case had severe disability, no dead cases. DSA showed clipping completely, parent artery clear, and long-term follow-up was still in progress.Conclusion Multi-technology combined microsurgical techniques which can effective improve the outcomes of intracranial giant aneurysms.
