经翼点锁孔手术治疗前循环动脉瘤

目的 探讨经翼点锁孔入路治疗前循环动脉瘤的可行性和手术方法。方法 对18例彰循环动脉瘤采用经翼点锁孔入路进行夹闭术，其中后交通动脉脉瘤9例，大脑中动脉瘤3例，前交通动脉动脉瘤6例。患者Hunt-Hess临床分级均在Ⅲ级以内。结果 均获得成功夹闭，术后无面神经损伤表现，平均手术时间缩短1～2h。1例左后交通动脉瘤术中破裂，术后出现一过性感觉和运动性失语。结论 经过慎重的选择病例以及术前周密的手术设计，经翼点锁孔入路治疗前循环动脉瘤是一种较理想的术式。

Surgical treatment of anterior circulation aneurysm via pterion keyhole approach

OBJECTIVE: To investigate the feasibility of pterion keyhole approach with minimal invasion for treatment of the anterior circulation aneurysm. METHOD: Aneurysm clipping through the pterion keyhole approach was performed in patients with anterior circulation aneurysms, including 9 with posterior communication artery aneurysms, 3 with middle cerebral artery aneurysms and 6 with anterior communication artery aneurysms, who were in stages I to III according to Hunt-Hess scale. RESULT: All the aneurysms were clipped successfully. One patient with a left posterior communication artery aneurysm developed transient sensory aphasia and motor aphasia after surgery due to intraoperative aneurysm rupture. No facial paralysis occurred due to damage of the facial nerve. CONCLUSION: The pterion keyhole approach is a very useful surgical approach for treatment of anterior circulation aneurysms on the basis of cautious determination of indications and careful operation planning.
