胃静脉曲张(GV)是门静脉高压症并发症之一,虽较食管静脉曲张发生率低,但GV出血不易控制,再出血及死亡率高。GV有着不同于食管静脉曲张的血管解剖和血流动力学特征,因此有着独特与之相对应的临床处理策略。为加深对GV血流动力学分型的认识,制定针对GV出血的个体化诊疗策略,中华医学会消化病学分会微创介入协作组邀请该领域部分专家制定本共识。

Gastric varices(GV), as one of the complications of portal hypertension, has a lower incidence than esophageal varices, but bleeding from GV is not easy to control and associated with a high rebleeding rate and high mortality.GV has different characteristics of vascular anatomy and hemodynamics from esophageal varices, with a unique corresponding clinical management strategy.In order to deepen the understanding of GV hemodynamic characteristics and formulate an individualized treatment strategy for GV bleeding, the Minimally Invasive Intervention Collaboration Group of the Gastroenterology Branch of the Chinese Medical Association invites some experts in this field to formulate this consensus.
