Abstract: Objective To explore the value of the located needles guided by intraoperative ultrasound in resection of brain cavernous malformations. Methods Fourteen patients diagnosed as brain cavernous malformations confirmed by preoperative CT and MRI. Detected by the located needles under intraoperative ultrasound guidance, 14 lesions were excised. Results Intraoperative ultrasound-guided needles accurately located 14 cases of patients with brain cavernous malformations. Fourteen lesions were removed successfully. The distances between lesions and the dura mater were 1.5-2.9 cm,the sizes of lesions were 0.8-2.8 cm. Fourteen lesions by color Doppler flow imaging showed point-like blood flow. Conclusions Brain cavernous malformations can be accurately detected by the located needles under intraoperative ultrasound guidance.
