Intracranial aneurysms surgery assisted by rigid endoscope
2010
Objective To evaluate the usefulness of endoscope in the microsurgical treatment of intraeranial aneurysms and analyze its benefits.risksand disadvantages.Mehtods We retrospectively study 63 patients with 66 aneurysms,treated between Janurary 2007 and October 2007,for whom the endoscope were used to assist the mierosurgical treatment of lesions.63 aneurysms were ruptured.In most of the cases,the endoscope was used in addition to microsurgical dissection and clipping(before,during and after clipping).Observation of the anatomic features of necks,perforators and selection of optimal clip position were performed.Results In the majority of cases,the endoscope was used.The clip Was repositioned in five aneurysm operations.including incomplete neck obliteration in 1 case of intracarotidophathalmic aneurysm,incomplete neck obliteration in 1 ICA-PCoA aneurysms,involvement of perforating vessels with the clip in 1 ICA-PCoA aneurysms,involvement of perforating vessels with the clip in 2 ACoA aneurysms.One patient experienced a mild temporal lobe contusion during the application of endoscope.There Was no intra-operative aneurysm rapture due to endoscope manipulation.Conclusioas Endoscope is vary useful during cerebral aneurysm surgery.It can provide valuable information for the assessment of regional anatomic features around aneurysm and improve the quality of aneurysm surgery.
