胃静脉曲张破裂出血死亡率达55％,内窥镜硬化/结扎、外科手术、经皮经肝消除及经颈肝内门体分流等疗法疗效欠佳且有较多并发症。1991年Kanagawa等报道采用逆行静脉球囊阻塞消除胃静脉曲张(BORTO),作者通过对一组14例肝硬化性胃静脉曲张患者接受这一新疗法的长期疗效研究来评估其临床可行性。14例中男5例、女9例,平均年龄62.6岁(52～74岁)。9例为预防性BORTO,其中5例胃静脉呈瘤样曲张,4例曲张静脉呈红色征
Gastric variceal bleeding mortality rate of 55%, endoscopic sclerosis / ligation, surgery, percutaneous transhepatic and transhepatic portosystemic shunts and other therapies are ineffective and have more complications. In 1991, Kanagawa et al. Reported retrograde venous balloon obstruction to eliminate gastric varices (BORTO). The authors evaluated the clinical feasibility of a long-term study of 14 patients with cirrhosis of the gastric varices who underwent this new therapy. There were 5 males and 9 females in 14 cases, with an average age of 62.6 years (52-74 years). 9 cases were prophylactic BORTO, of which 5 cases of gastric venous was tumor-like varicose, 4 cases of varicose veins showed red signs
