术中超声造影在脑动静脉畸形切除术中的应用

Objective To investigate the diagnosis potential of contrast agents imaging in AVM surgical treatment. Methods Twenty patients diagnosed as AVM comfirmed by preoperative CT, MRI and DSA were enrolled. The color Doppler flow imaging (CDFI), pulsed Doppler imaging and ultrasound contrast agents imaging in intraoperative guidance were used, the lesion location, depth, size and its relationship with the surrounding tissue were observed. The number of feeding arteries and draining veins by different methods were...
