经硬脑膜外-内入路治疗眼动脉段颈内动脉瘤的临床研究

目的探讨眼动脉段颈内动脉动脉瘤的手术入路及治疗方法。同时探索并介绍降低术后并发症的经验。方法采用硬脑膜外内入路直接夹闭眼动脉段动脉手术治疗眼动脉段颈内动脉瘤３１例,占同期４年全部动脉瘤的８３％。结果无手术死亡,术后合并症为１９％。术后造影证实动脉瘤全部被夹闭。结论硬脑膜外－内入路直接夹闭眼动脉段颈内动脉是眼动脉段颈内动脉瘤的最佳手术入路和治疗方法

Direct surgical clipping the carotid-ophthalmic aneurysms through a extradural-intradural approach

Objectives To exlore the approach for treating carotid ophthalmic aneurysms and introduce experience in reducing postoperative complications. Methods We treated 31 patients with carotid ophthalmic aneurysms, which accounted for 8.3% of all intracranial aneurysms we encountered in 1994 and 1997, by direct surgical clipping. Results No operative death occurred and the rate of postoperative complications was 19%. All aneurysms were occluded and later confirmed by angiography. Conclusion The direct clipping of aneurysms involving the carotid ophthalmic artery is best treated by the extradural intradural approach.
