Six cases demonstrating the utility of pulsed Doppler sonography as an aid in avoiding complications of aspiration and biopsy are presented. Duplex sonography combined with ultrasound needle guidance was helpful in identifying the vascular nature of masses in 3 cases and positively identifying and avoiding vascular structures within the needle path in 3 cases. The selective use of duplex sonography prior to aspiration biopsy provides information that should serve to minimize further the risks of hemorrhage associated with modern biopsy techniques.
本文介绍了6例病例，展示了脉冲多普勒超声在辅助避免抽吸和活检并发症方面的作用。双功超声结合超声针引导，在3例病例中有助于识别肿块的血管性质，在另外3例病例中能准确识别并避开针道内的血管结构。在抽吸活检前选择性使用双功超声可提供信息，应有助于进一步降低与现代活检技术相关的出血风险。
