目前,肝动脉化疗栓塞术(TACE)对于失去手术机会的肝癌已成为首选方法,而异位栓塞所致的并发症已成为影响其疗效的重要因素之一。肝胃间存在许多侧支通路或一些变异的动脉血管交通,认清这些血管非常重要,可有效地提高TACE的疗效,预防和尽量减少胃肠道并发症的发生。 At present, transcatheter arterial chemoembolization (TACE) has become the first choice for patients with liver cancer who have lost their chance of surgery. Complications caused by ectopic embolization have become one of the important factors that affect their efficacy. There are many collateral channels in the liver and stomach or some variations of arterial traffic. Recognizing these blood vessels is very important, which can effectively improve the curative effect of TACE and prevent and minimize the occurrence of gastrointestinal complications.
