Portal hypertension is a major cause of morbidity and mortality in patients with liver cirrhosis. Intrahepatic vascular resistance due to architectural distortion and intrahepatic vasoconstriction, increased portal blood flow due to splanchnic vasodilatation, and development of collateral circulation have been considered as major factors for the development of portal hypertension. Recently, sinusoidal remodeling and angiogenesis have been focused as potential etiologic factors and various researchers have tried to improve portal hypertension by modulating these new targets. This article reviews potential new treatments in the context of portal hypertension pathophysiology concepts.
门静脉高压是肝硬化患者发病和死亡的主要原因。肝内结构扭曲和肝内血管收缩导致的肝内血管阻力增加、内脏血管扩张引起的门静脉血流增加以及侧支循环的形成被认为是门静脉高压发生的主要因素。最近,窦状隙重塑和血管生成已成为潜在的病因因素受到关注,并且各种研究人员试图通过调节这些新靶点来改善门静脉高压。本文在门静脉高压病理生理学概念的背景下综述了潜在的新治疗方法。
