肝硬化门脉高压患者,门体之间侧支血管扩张,形成多处门体循环;在这些扩张的侧支血管中,食管胃底静脉曲张常导致上消化道出血,危及患者健康和生命,具有重要临床意义。在实施手术或介入治疗时,术前了解侧支血管的情况尤为重要;近年来,随着多层螺旋CT技术的发展及多种图像后处理技术的开发,多层螺旋CT门静脉成像能全面准确地显示肝硬化患者门体循环之间侧支血管的部位和范围,为肝硬化门脉高压患者治疗方法的选择和术前评估提供了可靠依据。
In patients with cirrhosis and portal hypertension, the collateral vessels in the portal are dilated to form multiple portal circulation. In these dilated collateral vessels, esophageal and gastric varices often lead to upper gastrointestinal bleeding, endangering patients’ health and life, Important clinical significance. In the implementation of surgery or interventional therapy, preoperative understanding of collateral vessels is particularly important; in recent years, with the development of multi-slice spiral CT technology and a variety of image post-processing technology, multi-slice spiral CT portography can be fully and accurately To show the location and extent of collateral vessels between the portal circulation of patients with cirrhosis, which provides a reliable basis for the selection and preoperative evaluation of the treatment of patients with cirrhosis and portal hypertension.
