作者用实时B型超声(频率5或7.5兆赫)于颅内占位病变16例(肿瘤12、血肿3、脓肿1和脊髓病变5例)。一般在手术开始后打开硬膜前即先行采用B超探测病灶,可对手术提供以下助益:1.选择硬膜切口的位置;2.活检前确定病灶的位置并选择活检或引流的进路(避开重要功能区);3.明确病灶的大小、范围、深度及其属性(实质性、囊性、坏死、多房性等);
The authors used real-time B-mode ultrasound (frequency 5 or 7.5 MHz) in intracranial space-occupying lesions of 16 (tumor 12, hematoma 3, abscess 1 and spinal cord lesions 5). Generally open the dural before surgery after the first use of B-probe ultrasound lesions, the surgery can provide the following benefits: 1. Choose the location of the dura incision; 2. Pre-biopsy to determine the location of the lesion and choose biopsy or drainage approach (To avoid the important functional area); 3 clear the size of the lesion, extent, depth and its attributes (substantive, cystic, necrotic, multilocular, etc.);
