【摘 要】Objective To explore the regional surgical anatomy, clinical
characteristics,neuroradiological manifestation, microsurgical skill and
clinical effectiveness of middle cerebral artery ( MCA) bifurcation
aneurysms. Methods The clinical data of 41 patients with MCA bifurcation
aneurysms treated by microsurgical operation in our hospital were
analyzed restrospectively , of whom 39 patients presented with clinical
manifestations of aneurysmal rupture.According to Hunt-Hess
classification, 5 belonged in grade 0 ~ Ⅰ , 15 in grade Ⅱ , 11 in grade
Ⅲ ,9 in grade Ⅳ and 1 in grade Ⅴ. All patients were made a definite
diagnosis by 64 rows helical CT angiography ( CTA). 41 patients were
performed micorsurgical management through operation of transpterional
approach or extended transpterional approach. The multiple intracranial
aneurysms were treated through the method of combining early-stage
with select-stage operation and one-stage with two-stage operation, the
operating principle was the ruptured aneurysm been treated firstly and the
unruptured aneurysm been treated secondly. Results Clipping was
carrying out in 36 cases, clipping plus wrapping in 4, clipping in one side
aneurysm and another side one did not treat in 1.Surgical outcome were good in 31 cases, light disability in 6, severe disability in 2 and 2 in
dead.Conclusion The surgical outcome are predominance that MCA
bifurcation aneurysms are performed microsurgical operation. The regional
surgical anatomy of MCA bifurcation aneurysms should be clearly borne in
mind in order to avoid the damage to the arteries and postoperative
neurological deficits. Emergency hematoma evacuation and aneurysms
clipping should be performed in the patients with intracerebral hematoma
due to aneurysm rupture.%目的 探讨大脑中动脉(MCA)分叉部动脉瘤的解剖特点、临床特征、影像学表现、显微手术技巧及临床疗效.方法 回顾分析41 例MCA
分叉部动脉瘤显微外科治疗患者的临床资料,39 例有动脉瘤破裂出血的临床表现,按Hunt-Hess 分级:0~Ⅰ级5 例,Ⅱ级15 例,Ⅲ级11 例,Ⅳ级9 例,Ⅴ级1 例.64 排螺旋CT 血管造影(CTA)确诊.41 例均行显微手术治疗,手术入路为翼点入路或扩大翼点入路.对多发动脉瘤采取早期与择期、一期与分期相结合的方法处理动脉瘤,原则是先处理破裂动脉瘤,再处理未破裂动脉瘤.结果 动脉瘤夹闭38 例,动脉瘤夹闭+包裹2 例,夹闭一侧动脉瘤,另一侧动脉瘤未处理1 例.依据GOS 判断:优良31 例,轻残6 例,重残2 例,死亡2 例.结论 显微外科手术治疗MCA 分叉部动脉瘤效果显著.熟悉MCA 分叉部动脉瘤的解剖特征有助于减少术中血管损伤和术后神经功能障碍;对合并脑内血肿的MCA 分叉部动脉瘤,应急诊手术清除血肿并夹闭动脉瘤.
