微血管多普勒超声在颅内巨大动脉瘤手术中的应用

目的探讨在颅内巨大动脉瘤手术中微血管多普勒超声的应用。方法分别对23例颅内巨大动脉瘤患者进行手术直接夹闭或者动脉瘤孤立＋血管架桥手术,在动脉瘤夹闭前及夹闭后应用微血管多普勒对动脉瘤及邻近血管进行血流速度检测,在动脉瘤孤立后进行移植血管和吻合血管血流的检测。结果巨大动脉瘤内血流的多普勒波谱主要表现有4种。5例直接夹闭动脉瘤中,2例在夹闭后证实有载瘤动脉或邻近血管的狭窄。15例血管架桥手术中,多普勒检测移植血管均通畅。结论微血管多普勒超声在颅内巨大动脉瘤手术中,是一种简便、安全有效的监测技术。

Application of intraoperative microvascular Doppler ultrasonography in intracranial giant aneurysm surgery

Objective To study the application of intraoperative color Doppler ultrasonography in intracranial giant aneurysm surgery. Methods Twenty-three patients with intracranial giant aneurysm were treated by clipping or by trapping the aneurysm in combination with bypass surgery. Color Doppler ultrasonography was conducted to examine the blood flow velocity in the aneurysml sac and its adjacent vessels before and after the aneurysm was clipped, or to examine the blood flow velocity and direction in the grafted vessels after trapping and bypass surgery. Results Four kinds of Doppler ultrasonography waves were observed in giant aneurysms. Of the 5 patients with their aneurysm directly clipped, 2 had stricture of tumor-carrying artery and its adjacent vessels. The grafted blood vessels were patent in all the 15 patients after bypass surgery. Conclusion Color Doppler ultrasonography is a feasible, safe, and reliable monitoring technique in giant aneurysm surgery.
