SYSTEM AND METHOD FOR TREATING HEPATIC AREA VEIN OCCLUSION

摘要

A system and a method are disclosed for treating hepatic area vein occlusion problem. There are five major techniques, used in combined manner or separately, showing effective cure rate. The first technique is to use multiple types of guiding wire through-to-through skills. The second technique is to use one or more accessory hepatic veins (AHV) to drain hepatic blood into inferior vena cava for decreasing pressure inside the liver. The third technique is to puncture through occlusion of veins. The fourth technique is reverse direction membrane puncture. The fifth technique is thrombosis handling.
