众所周知肝动脉的栓塞化疗（TACE）对肝癌有很好的疗效[1]。但大的肝动静脉短路则是限制TACE施实的重要禁忌证之一，鉴别肝脏动静脉短路国内主要靠数字减影血管造影（DSA）来显示，由于设备昂贵而影响TACE的普及。我们自1995年11月至1997年4月应用声学造影技术显示肝动静脉短路
It is well known that transcatheter arterial chemoembolization (TACE) has a good effect on liver cancer [1]. However, large hepatic arteriovenous shunts are one of the important contraindications for restricting TACE. The identification of liver arteriovenous shunts in China is mainly based on digital subtraction angiography (DSA), which affects the popularity of TACE due to expensive equipment. We have applied ultrasound contrast angiography to show liver and vein short circuit from November 1995 to April 1997
