Objective: To introduce the surgical techniques of aneurysmal sac excision and parent vessel reconstruction in treatment for giant aneurysms. 目的:介绍颅内巨大动脉瘤体切除和载瘤血管重建手术方法。
Methods Forty-one cases were treated with coils to block the aneurysmal sac via femoral artery approach. 方法对41例前交通动脉瘤患者采用经皮股动脉穿刺行全脑选择性血管造影术,应用微弹簧圈进行动脉瘤囊内栓塞;
The small or giant aneurysm, aneurysmal sac, wall, body, mass effect can be showed by the source images, its signals of aneurysmal neck and sac was higher than MRA. 原始图像可发现小的和巨大动脉瘤,显示瘤腔、瘤壁、瘤体、占位效应准确,其瘤颈、瘤腔的信号多高于MRA;
Microcatheters were introduced into the aneurysmal sac through stent mesh and GDC were used to embolize the aneurysms in 13 cases. Another 4 patients were treated only by the stent placement. 其中13例通过支架网孔将微导管送入动脉瘤腔,填塞电解可脱弹簧圈,4例仅放置支架治疗。
Aneurysmal sac excision and parent vessel reconstruction in treatment for giant aneurysms 动脉瘤体切除和载瘤血管重建治疗巨大动脉瘤
Result In the 16 cases treated by the proximal balloon occlusion, 13 were cured angiographically with complete obliteration of the aneurysmal sac and in 4 of them the aneurysms disappeared both on CT and MRI. 结果16例采用球囊闭塞近端载瘤动脉病例中13例动脉瘤完全闭塞,其中4例动脉瘤完全消失。
